COL-3, a chemically modified tetracycline, inhibits lipopolysaccharide-induced microglia activation and cytokine expression in the brain. Full Text Available Microglia activation results in release of proinflammatory molecules including cytokines , which contribute to neuronal damage in the central nervous system CNS if not controlled.

Tetracycline antibiotics such as minocycline inhibit microglial activation and cytokine expression during CNS inflammation. COL-3 has been described to have no antibacterial activity. Our data show that COL-3 has some antibacterial activity against S. Hyperin is a flavonoid compound derived from Ericaceae, Guttifera, and Celastraceae that has been shown to have various biological effects, such as anti-inflammatory and anti-oxidant effects.

However, there is no evidence to show the protective effects of hyperin on lipopolysaccharide LPS -induced acute kidney injury AKI. The effects of hyperin on blood urea nitrogen BUN and serum creatinine were also detected. The levels of BUN and creatinine were also suppressed by hyperin. Hyperin has potential application prospects in the treatment of sepsis-induced AKI.

However, the regulation of translational elongation is poorly understood. Full Text Available Background. Tanshinone IIA sodium sulfonate TSS is known to possess anti-inflammatory effects and has exhibited protective effects in various inflammatory conditions; however, its role in lipopolysaccharide- LPS - induced intestinal injury is still unknown.

The intestinal tissue injury was analyzed by HE staining. A number of autophagosomes were also observed under electron microscopy. Furthermore, TSS treatment could effectively upregulate LPS-induced decrease of autophagy levels, as evidenced by the increased expression of LC3 and Beclin-1, and more autophagosomes.

The protective effect of TSS on LPS-induced small intestinal injury may be attributed to the inhibition of inflammatory factors and promotion of autophagy levels. The present study may provide novel insight into the molecular mechanisms of TSS on the treatment of intestinal injury. Cytokine and acute phase protein gene expression in liver biopsies from dairy cows with a lipopolysaccharide - induced mastitis.

A minimally invasive liver biopsy technique was tested for its applicability to study the hepatic acute phase response APR in dairy cows with Escherichia coli lipopolysaccharide LPS -induced mastitis. Lipopolysaccharide-induced mastitis resulted in a time-dependent production of inflammatory cytokines and SAA and Hp in the liver of dairy cows Glycolipids are the major constituent of the thylakoid membrane of higher plants and have a variety of biological and pharmacological activities.

However, anti-inflammatory effects of glycolipids on vascular endothelial cells have not been elucidated. Here, we investigated the effect of glycolipids extracted from spinach on lipopolysaccharides LPS -induced endothelial inflammation and evaluated the underlying molecular mechanisms.

These findings suggest that glycolipids from spinach may have a potential therapeutic use for inflammatory vascular diseases. In the present study, the chroman KL compound was found to inhibit lipopolysaccharide LPS -induced nitric oxide production in macrophages RAW Systemic administration of nt-pTMD showed a significant therapeutic effect on LPS-induced sepsis model by inhibiting pro-inflammatory cytokines secretion.

Therefore, nt-pTMD can be a novel therapeutics for the treatment of various inflammatory diseases, including sepsis, where a transcription factor has a key role in pathogenesis, and further allows us to discover new functions of p65 under normal physiological condition without genetic alteration.

Full Text Available Berberine hydrochloride is an isoquinoline type alkaloid extracted from Berberidaceae, Rutaceae, and other plants. Previous reports have shown that berberine hydrochloride has anti-inflammatory properties. However, the underlying molecular mechanisms remain unclear. In this study, a lipopolysaccharide- LPS - induced murine model of mastitis was established to explore the anti-inflammatory action of berberine hydrochloride. The pathological and histopathological changes of the mammary glands were observed.

Berberine hydrochloride is an isoquinoline type alkaloid extracted from Berberidaceae, Rutaceae, and other plants. Cytokine gene expression of peripheral blood lymphocytes Mar 20, Key words: Lipopolysaccharide, lymphocytes, TLRs, cytokines.

Ilexgenin A, a novel pentacyclic triterpenoid extracted from Aquifoliaceae shows reduction of LPS-induced peritonitis in mice. Ilexgenin A IA is a novel pentacyclic triterpenoid, which extracted from leaves of Ilex hainanensis Merr. In the present study, we aim to explore anti-inflammatory activity of IA on LPS-induced peritonitis and its underlying molecular mechanism. The results determined that IA was capable of suppressing peritonitis in mice induced by intraperitoneal i.

Furthermore, the results showed that IA dramatically inhibited levels of inflammatory cells infiltration in peritoneal cavity and serum in LPS-induced mice peritonitis model. These results demonstrated that IA might as an anti-inflammatory agent candidate for inflammatory disease therapy.

A central role for the mammalian target of rapamycin in LPS-induced anorexia in mice. Bacterial lipopolysaccharide LPS , also known as endotoxin, induces profound anorexia. However, the LPS-provoked pro-inflammatory signaling cascades and the neural mechanisms underlying the development of anorexia are not clear. Mammalian target of rapamycin mTOR is a key regulator of metabolism, cell growth, and protein synthesis.

These results suggest promising approaches for the prevention and treatment of LPS-induced anorexia. Full Text Available Stem cell therapy for tissue regeneration has several limitations in the fact that transplanted cells could not survive for a long time. For solving these limitations, many studies have focused on the antioxidants to increase survival rate of neural stem cells NSCs.

Melatonin, an antioxidant synthesized in the pineal gland, plays multiple roles in various physiological mechanisms. Melatonin exerts neuroprotective effects in the central nervous system. To determine the effect of melatonin on NSCs which is in LPS-induced inflammatory stress state, we first investigated nitric oxide NO production and cytotoxicity using Griess reagent assays, LDH assay, and neurosphere counting. Based on our results, we conclude that melatonin may be an important factor for the survival and proliferation of NSCs in neuroinflammatory diseases.

The main active component is alliin S-allyl cysteine sulfoxide, a potent antioxidant with cardioprotective and neuroprotective actions. In addition, it helps to decrease serum levels of glucose, insulin, triglycerides, and uric acid, as well as insulin resistance, and reduces cytokine levels. However its potential anti-inflammatory effect is unknown.

Furthermore, the gene expression profile by microarrays evidentiate an upregulation of genes involved in immune response and downregulation of genes related with cancer. The present results have shown that alliin is able to suppress the LPS inflammatory signals by generating an anti-inflammatory gene expression profile and by modifying adipocyte metabolic profile.

Xanthohumol Xn, a principal prenylflavonoid, possesses anti-inflammation and anti-oxidant activities. Accordingly, we focused on exploring the protective effect of Xn in the context of ALI and the involvement of underlying molecular mechanisms.

Keywords: Xanthohumol, Acute lung injury, Oxidative stress. DNA methylcytosine dioxygenase ten-eleven translocation 2 enhances lipopolysaccharide-induced cytokine expression in human dental pulp cells by regulating MyD88 hydroxymethylation. Ten-eleven translocation 2 TET2 is a recently discovered DNA methylcytosine dioxygenase that plays important roles in inflammatory disease.

However, its role in the inflammatory response of dental pulp is unknown. Thus, TET2-dependent DNA demethylation might play an important role in dental pulp inflammation as an epigenetic regulator. Post translational modifications, ubiquitination and its reversal by deubiquitination play an important role in regulating innate immune system. USP12 is a poorly studied deubiquitinase reported to regulate T-cell receptor signalling however the functional role of USP12 in macrophages, the principal architects of inflammation, is unknown.

Thus, in this study we probed the involvement of USP12 in macrophage mediated inflammatory responses using bacterial endotoxin, LPS, as the model system. The potent vasoconstrictor Endothelin-1 ET-1 is known to be upregulated in the setting of infection, and elicits its effect by binding to the ET A receptor. We hypothesize that the administration of BQ post LPS exposure will dismantle a positive feedback loop observed with pro-inflammatory cytokines upstream of ET On GD Changes at both the level of transcription and translation were observed in uterus and placenta in the ET-1 axis and in pro- and anti-inflammatory cytokines over the course of 12 h.

We discovered that BQ, when administered 10 h post LPS, is capable of increasing production of uterine and placental Interleukin, causing a shift away from the pro-inflammatory state. Our results reinforce the role of ET-1 at the maternal fetal interface and highlight the potential benefit of ET A receptor blockade via the suppression of ET-1, and induction of a Th2 cytokine dominant state.

However, no studies have examined whether andrographolide And reduces LPS-induced myocardial malfunction. Methods: Left ventricular systolic and diastolic functions were examined using echocardiography. NO oxidation products were determined using Griess reagent. Oxidative injury was determined by measuring myocardial lipid peroxidation and superoxide dismutase activity. Results: And blunted LPS-induced myocardial malfunctions in mice.

Cardiac apoptosis was attenuated via incubation with And, but the extent of oxidative injury remained unaffected. Full Text Available The iridoids of Hedyotis diffusa Willd play an important role in the anti-inflammatory process, but the specific iridoid with anti-inflammatory effect and its mechanism has not be thoroughly studied. An iridoid compound named scandoside SCA was isolated from H. Its anti-inflammatory mechanism was confirmed by in intro experiments and molecular docking analyses.

LPS-induced systemic inflammation is more severe in P2Y12 null mice. Thienopyridines are a class of antiplatelet drugs that are metabolized in the liver to several metabolites, of which only one active metabolite can irreversibly antagonize the platelet P2Y12 receptor. Possible effects of these drugs and the role of activated platelets in inflammatory responses have also been investigated in a variety of animal models, demonstrating that thienopyridines could alter inflammation.

However, it is not clear whether it is caused only by the P2Y12 antagonism or whether off-target effects of other metabolites also intervene. To address this question, we investigated P2Y12 KO mice during a LPS-induced model of systemic inflammation, and we treated these KO mice with a thienopyridine drug clopidogrel. Contrary to the reported effects of clopidogrel, numbers of circulating WBCs and plasma levels of cytokines were increased in LPS-exposed KO mice compared with WT in this inflammation model.

Moreover, both spleen and bone marrow show an increase in cell content, suggesting a role for P2Y12 in regulation of bone marrow and spleen cellular composition. Finally, the injury was more severe in the lungs of KO mice compared with WT. Interestingly, clopidogrel treatments also exerted protective effects in KO mice, suggesting off-target effects for this drug.

In conclusion, the P2Y12 receptor plays an important role during LPS-induced inflammation, and this signaling pathway may be involved in regulating cell content in spleen and bone marrow during LPS systemic inflammation. Furthermore, clopidogrel may have effects that are independent of P2Y12 receptor blockade. Full Text Available The ocean is a rich resource of flora, fauna, food, and biological products. We found a wild-type bacterial strain, Pseudoalteromonas sp.

M2, from marine water and isolated various secondary metabolites. Pseudane-VII is a compound isolated from the Pseudoalteromonas sp. M2 metabolite that possesses anti-melanogenic activity. Inflammation is a response of the innate immune system to microbial infections. Macrophages have a critical role in fighting microbial infections and inflammation. Recent studies reported that various compounds derived from natural products can regulate immune responses including inflammation.

However, the anti-inflammatory effects and mechanism of pseudane-VII in macrophages are still unknown. In this study, we investigated the anti-inflammatory effects of pseudane-VII. These findings may provide new approaches in the effort to develop anti-inflammatory therapeutics.

The ocean is a rich resource of flora, fauna, food, and biological products. Sepsis-induced cardiac apoptosis is one of the major pathogenic factors in myocardial dysfunction. As it enhances numerous proinflammatory factors, lipopolysaccharide LPS is considered the principal mediator in this pathological process. However, the detailed mechanisms involved are unclear.

In this study, we attempted to explore the mechanisms involved in LPS-induced cardiomyocyte apoptosis. Overexpression of miR protected the cardiomyocytes against LPS-induced apoptosis. The effect of tuna eyeball oil TEO on lipopolysaccharide LPS -induced inflammation in macrophage cells was investigated. The rate of formation of ear edema was reduced compared to that in the control at the highest dose tested.

These results suggested that TEO may have a significant effect on inflammatory factors and be a potential anti-inflammatory therapeutic. Synthesis and optimization of novel allylated mono-carbonyl analogs of curcumin MACs act as potent anti-inflammatory agents against LPS-induced acute lung injury ALI in rats. Most of the obtained compounds exhibited improved water solubility as a hydrochloride salt compared to lead molecule 8f.

These results suggest that 7a could be therapeutically beneficial for use as an anti-inflammatory agent in the clinical treatment of acute lung injury ALI. Human umbilical cord mesenchymal stem cells reduce systemic inflammation and attenuate LPS-induced acute lung injury in rats. Full Text Available Abstract Background Mesenchymal stem cells MSCs possess potent immunomodulatory properties and simultaneously lack the ability to illicit immune responses.

Hence, MSCs have emerged as a promising candidate for cellular therapeutics for inflammatory diseases. Within the context of this study, we investigated whether human umbilical cord-derived mesenchymal stem cells UC-MSCs could ameliorate lipopolysaccharide- LPS - induced acute lung injury ALI in a rat model. The rats were sacrificed at 6, 24, and 48 hours after injection.

Serum, bronchoalveolar lavage fluid BALF, and lungs were collected for cytokine concentration measurements, assessment of lung injury, and histology. Conclusion UC-MSCs noticeably increased the survival rate of rats suffering from LPS-induced lung injury and significantly reduced systemic and pulmonary inflammation.

Promoting anti-inflammatory homeostasis and reducing oxidative stress might be the therapeutic basis of UC-MSCs. Olgun, Nicole S. The purpose of our investigation was designed to reveal the effect of andrographolide on various aspects of LPS induced inflammation in vivo and in vitro. These results suggest andrographolide may be considered as an effective and safe drug for the potential treatment of ALI.

This study explored the effect of miRb on inflammatory injury in chondrogenic cells. Full Text Available The fruit hull of Gleditsia sinensis FGS has been prescribed as a traditional eastern Asian medicinal remedy for the treatment of various respiratory diseases, but the efficacy and underlying mechanisms remain poorly characterized. Here, we explored a potential usage of FGS for the treatment of acute lung injury ALI, a highly fatal inflammatory lung disease that urgently needs effective therapeutics, and investigated a mechanism for the anti-inflammatory activity of FGS.

These results suggest that FGS effectively suppresses neutrophilic lung inflammation, which can be associated with, at least in part, FGS-activating anti-inflammatory factor Nrf2. Full Text Available Background: Sickle cell anaemia is an inherited disease in which the red blood cells become rigid and sticky, and change from being disc-shaped to being crescent-shaped. The change in shape is due to the presence of an abnormal form of haemoglobin. This results in severe pain and damage to some organs.

Aim and Objective: The study was carried out to determine the levels of cytokine in sickle cell anemia. Material and Methods: Thirty confirmed sickle cell patients in steady state HbSS-SS and thirty persons with normal haemoglobin HbAA as well as sixteen sickle cell disease in crises HbSS-cr between the ages of 15 to 30 years were selected in this study. Also, cytokines could be used as an inflammatory marker as well as related marker in disease severity and hence therapeutic intervention.

Hence, MAT provides higher safety since it evidences an unwanted biological response, which is not completely controlled and is overlooked by the RPT. Sepsis, a clinical syndrome occurring in patients following infection or injury, is a leading cause of mortality worldwide.

It involves uncontrolled inflammatory response resulting in multi-organ failure and even death. Isoalantolactone IAL , a sesquiterpene lactone, is known for its anti-cancer effects. Taken together, our data suggest that IAL may represent a potentially new drug candidate for the treatment of sepsis. Caspase-8 regulates the expression of pro- and anti-inflammatory cytokines in human bone marrow-derived mesenchymal stromal cells.

Mesenchymal stem cells, also called mesenchymal stromal cells, MSCs, have great potential in stem cell therapy partly due to their immunosuppressive properties. How these cells respond to chronic inflammatory stimuli is therefore of importance. Toll-like receptors TLR s are innate immune receptors that mediate inflammatory signals in response to infection, stress, and damage.

Here we investigated the role of caspase-8 in regulating TLR-induced cytokine production from human bone marrow-derived mesenchymal stromal cells hBMSCs. Caspase-8 was also inhibited using a caspase-8 inhibitor, z-IEDT. Caspase-8 appears to modulate hBMSCs into gaining a pro-inflammatory phenotype. Therefore, inhibiting caspase-8 in hBMSCs might promote an immunosuppressive phenotype which could be useful in clinical applications to treat inflammatory disorders. Moen, Siv H. Abstract Introduction Mesenchymal stem cells, also called mesenchymal stromal cells, MSCs, have great potential in stem cell therapy partly due to their immunosuppressive properties.

Full Text Available The Chilean strawberry fruit has high content of antioxidants and polyphenols. Previous studies evidenced antioxidant properties by in vitro methods. However, the antioxidant effect and its impact as functional food on animal health have not been evaluated. Transaminases and histological studies revealed a reduction in liver injury in rats fed with strawberry aqueous extract compared with the control group.

Altogether, the evidence suggests that dietary supplementation of rats with a Chilean white strawberry aqueous extract favours the normalization of oxidative and inflammatory responses after a liver injury induced by LPS. The Chilean strawberry fruit has high content of antioxidants and polyphenols. Sepsis, the systemic inflammatory response syndrome SIRS with infection is one of the leading causes of death in critically ill patients in the developed world due to the lack of effective antisepsis treatments.

Full Text Available Abstract Background The resolution of inflammatory responses in the lung has not been described in detail and the role of specific cytokines influencing the resolution process is largely unknown. We documented the inflammatory cell types and cytokines found in the bronchoalveolar lavage fluid BALF, and epithelial changes in the axial airway and investigated whether IL may play a role in the resolution process by reducing its levels with anti-IL antibodies.

Results Three major stages of inflammation and resolution were observed in the BALF during the resolution. The first stage was characterized by PMNs that increased over 3 h to 1 d and decreased to background levels by d 6—8. The second stage of inflammation was characterized by macrophage influx reaching maximum numbers at d 6 and decreasing to background levels by d A third stage of inflammation was observed for lymphocytes which were elevated over d 3—6.

Interestingly, IL and IL-9 levels in the BALF showed a cyclic pattern with peak levels at d 4, 8, and 16 while decreasing to background levels at d 1—2, 6, and Depletion of IL caused decreased PMN numbers at d 2, but no changes in inflammatory cell number or type at later time points. Conclusion These data suggest that IL plays a role in enhancing the LPS-induced neutrophilic inflammation of the lung, but does not affect the resolution of inflammation.

Fisetin administration improves LPS-induced acute otitis media in mouse in vivo. Acute otitis media is one of the most common infectious diseases worldwide in spite of the widespread vaccination. The present study was conducted to explore the effects of fisetin on mouse acute otitis media models. The animal models were established by lipopolysaccharide LPS injection into the middle ear of mice via the tympanic membrane. Fisetin was administered to mice for ten days through intragastric administration immediate after LPS application.

Fisetin reduced mucosal thickness caused by LPS. Brain microvascular pericytes are immunoactive in culture: cytokine , chemokine, nitric oxide, and LRP-1 expression in response to lipopolysaccharide. Full Text Available Abstract Background Brain microvascular pericytes are important constituents of the neurovascular unit.

These cells are physically the closest cells to the microvascular endothelial cells in brain capillaries. They significantly contribute to the induction and maintenance of the barrier functions of the blood-brain barrier. However, very little is known about their immune activities or their roles in neuroinflammation. Here, we focused on the immunological profile of brain pericytes in culture in the quiescent and immune-challenged state by studying their production of immune mediators such as nitric oxide NO, cytokines , and chemokines.

Methods Supernatants were collected from primary cultures of mouse brain pericytes. Release of nitric oxide NO was measured by the Griess reaction and the level of S-nitrosylation of pericyte proteins measured with a modified "biotin-switch" method. Specific mitogen-activated protein kinase MAPK pathway inhibitors were used to determine involvement of these pathways on NO production.

Cytokines and chemokines were analyzed by multianalyte technology. The expression of both subunits of LRP-1 was analyzed by western blot. Nitrative stress resulted in S-nitrosylation of cellular proteins. Pericyte expressions of both subunits of. Diabetic retinopathy DR , an important complication of diabetes mellitus DM , is not well understood. This study explores changes in Th1 and Th2 cytokine expression during DR.

Cytokines such as tumor necrosis factor-alpha TNF-alpha and interleukin-1beta IL-1beta are assumed to mediate anorexia during bacterial infections. To improve our understanding of the role that these two cytokines serve in mediating infection during anorexia, we investigated the ability of pentoxifylline PTX , a potent inhibitor of TNF-alpha production, to block the anorectic effects of the bacterial products lipopolysaccharide LPS and muramyl dipeptide MDP in rats.

PTX administration also attenuated the tolerance that is normally observed with a second injection of LPS. This is consistent with the hypothesis that TNF-alpha plays a major role in the anorexia associated with bacterial infection. Protection against LPS-induced cartilage inflammation and degradation provided by a biological extract of Mentha spicata.

RA has demonstrated significant anti-inflammatory activity in vitro and in small rodents; thus it was hypothesized that this plant would demonstrate significant anti-inflammatory activity in vitro. The objectives of this study were: a to develop an in vitro extraction procedure which mimics digestion and hepatic metabolism, b to compare anti-inflammatory properties of High-Rosmarinic-Acid Mentha spicata HRAM with wild-type control M.

No anti-inflammatory or chondroprotective effects of RA metabolites on cartilage explants were identified. Conclusions Our biological extraction procedure produces. AbstractBackgroundCompelling evidence has implicated neuroinflammation in the pathogenesis of a number of neurodegenerative conditions. We sought to identify signaling kinases responsible for cytokine production and to delineate the complex interactions which govern time-related responses to lipopolysaccharide LPS.

MethodsWe examined the time-related changes in certain signaling events and the release of proinflammatory cytokines from LPS-stimulated co-cultures of astrocytes and microglia isolated from neonatal rats. Effects of prebiotics on immune system and cytokine expression.

Nowadays, use of prebiotics as feed and food additives has received increasing interest because of the beneficial effects of prebiotics on the health of animals and humans. One of the beneficial effects of prebiotics is stimulation of immune system, which can be direct or indirect through increasing population of beneficial microbes or probiotics, especially lactic acid bacteria and bifidobacteria, in the gut.

An important mechanism of action of probiotics and prebiotics, by which they can affect the immune system, is changing the expression of cytokines. The present review tried to summarize the findings of studies that investigated the effects of prebiotics on immune system with focusing on their effects on cytokine expression. Generally, most of reviewed studies indicated beneficial effects for prebiotics in terms of improving immune system, by increasing the expression of anti-inflammatory cytokines , while reducing the expressions of proinflammatory cytokines.

However, most of studies mainly considered the indirect effects of prebiotics on the immune system through changing the composition and population of gut microbiota , and their direct effects still need to be further studied using prebiotics with different degree of polymerization in different hosts. Full Text Available The unregulated activation of microglia following stroke results in the production of toxic factors that propagate secondary neuronal injury.

Salidroside has been shown to exhibit protective effects against neuronal death induced by different insults. However, the molecular mechanisms responsible for the anti-inflammatory activity of salidroside have not been elucidated clearly in microglia. In the present study, we investigated the molecular mechanism underlying inhibiting LPS-stimulated BV2 microglial cell mobility of salidroside.

The protective effect of salidroside was investigated in microglial BV2 cell, subjected to stretch injury. Moreover, transwell migration assay demonstrated that salidroside significantly reduced cell motility. Our results also indicated that salidroside suppressed LPS-induced chemokines production in a dose-dependent manner, without causing cytotoxicity in BV2 microglial cells. These results suggest that salidroside possesses a potent suppressive effect on cell migration of BV2 microglia and this compound may offer substantial therapeutic potential for treatment of ischemic strokes that are accompanied by microglial activation.

Adrenaline stimulates the proliferation and migration of mesenchymal stem cells towards the LPS-induced lung injury. Bone marrow-derived mesenchymal stem cells BMSCs could modulate inflammation in experimental lung injury. On the other hand, adrenergic receptor agonists could increase DNA synthesis of stem cells. BMSCs were cultured with adrenergic receptor agonists or antagonists. A preliminary animal experiment was conducted to validate the findings in ex vivo study.

Adrenaline-stimulated BMSCs decreased the inflammation of LPS-stimulated macrophages, probably through the expression and secretion of several paracrine factors. Adrenaline reduced the extent of injury in LPS-injured rats. Our data indicate that adrenaline-stimulated BMSCs might contribute to the prevention from acute lung injury through the activation of adrenergic receptors, promotion of proliferation and migration towards injured lung, and modulation of inflammation.

Plasma cytokine expression in adolescent chronic fatigue syndrome. Low-grade systemic inflammation does not appear to be a central part of adolescent CFS pathophysiology. LPS-induced lung inflammation in marmoset monkeys - an acute model for anti-inflammatory drug testing. Full Text Available Increasing incidence and substantial morbidity and mortality of respiratory diseases requires the development of new human-specific anti-inflammatory and disease-modifying therapeutics.

Therefore, new predictive animal models that closely reflect human lung pathology are needed. In the current study, a tiered acute lipopolysaccharide LPS-induced inflammation model was established in marmoset monkeys Callithrix jacchus to reflect crucial features of inflammatory lung diseases. Firstly, in an ex vivo approach marmoset and, for the purposes of comparison, human precision-cut lung slices PCLS were stimulated with LPS in the presence or absence of the phosphodiesterase-4 PDE4 inhibitor roflumilast.

The corticosteroid dexamethasone was used as treatment control. Secondly, in an in vivo approach marmosets were pre-treated with roflumilast or dexamethasone and unilaterally challenged with LPS. This inflammatory response was significantly suppressed by roflumilast and dexamethasone.

The close similarity of marmoset and human lungs regarding LPS-induced inflammation and the significant anti-inflammatory effect of approved pharmaceuticals assess the suitability of marmoset monkeys to serve as a promising model for studying anti-inflammatory drugs. However, administration of INH induces severe hepatic toxicity in some patients. Previously, we establish a rat model of INH hepatotoxicity utilizing the inflammatory stress theory, in which bacterial lipopolysaccharide LPS potentially enhanced INH toxicity.

These enhancing activities ranged between augmenting the inflammatory stress, oxidative stress, alteration of bile acid homeostasis, and CYP2E1 over- expression. Although pre-treatment with dexamethasone DEX helped overcome both inflammatory and oxidative stress which ended-up in alleviation of LPS augmenting effects, but still minor toxicities were being detected, alongside with CYP2E1 over expression. A wide range of anti-inflammatory chemicals have been used to treat such diseases while presenting high toxicity and numerous side effects.

Here, we report the anti-inflammatory effect of a non-toxic, cost-effective natural agent, polyphenolic extract from the Tunisian quince Cydonia oblonga Miller. Concomitantly, quince polyphenols enhanced the level of the anti-inflammatory cytokine IL secreted by LPS-treated macrophages. Overall, our data indicate that quince peel polyphenolic extract induces a potent anti-inflammatory effect that may prove useful for the treatment of inflammatory diseases and that a quince-rich regimen may help to prevent and improve the treatment of such diseases.

Niclosamide 5-chloro-salicyl- 2-chloronitro anilide is an oral anthelmintic drug used for treating intestinal infection of most tapeworms. Recently, niclosamide was shown to have considerable efficacy against some tumor cell lines, including colorectal, prostate, and breast cancers, and acute myelogenous leukemia.

Specifically, the drug was identified as a potent inhibitor of signal transducer and activator of transcription 3 STAT3 , which is associated with osteoclast differentiation and function. Taken together, our results show that niclosamide is effective in suppressing osteoclastogenesis and may be considered as a new and safe therapeutic candidate for the clinical treatment of osteoclast-related diseases such as osteoporosis.

Lipoxin A4 and platelet activating factor are involved in E. Full Text Available CFTR cystic fibrosis transmembrane conductance regulator is expressed by both neutrophils and platelets. Lack of functional CFTR could lead to severe lung infection and inflammation. Traditional medicines that stimulate or modulate the immune system can be used as innovative approaches to treat immunological diseases. The herbal medicine IMOD has been shown to strongly modulate immune responses in several animal studies as well as in clinical trials.

However, little is known. We evaluated the effects of TR6 on lipopolysaccharide-induced mastitis in mice. In vitro, primary mouse mammary epithelial cells and neutrophils were used to investigate the effects of TR6 on LPS-induced inflammatory responses.

TR6 may be a promising therapeutic reagent for mastitis treatment. Published by Elsevier B. The facts described above demonstrated that PWM-induced cells have the function of T-helper cells and play more important role in the synergy than LPS-induced cells. Modulation of LPS induced inflammatory response by Lawsonyl monocyclic terpene from the marine derived Streptomyces sp. Inhibition of LPS-induced splenocyte proliferation by ortho-substituted polychlorinated biphenyl congeners.

Polychlorinated biphenyls PCBs are persistent environmental contaminants, and their ubiquitous nature has prompted studies of their potential health hazards. As a result of their lipophilic nature, PCBs accumulate in breast milk and subsequently affect the health of offspring of exposed individuals. Biological effects of PCBs in animals have mostly been attributed to coplanar congeners, although effects of ortho congeners also have been demonstrated.

The immunotoxic endpoints investigated included splenocyte viability, lipopolysaccharide LPS -induced splenocyte proliferation, and LPS-induced antibody secretion. Congeners with multiple ortho chlorines preferentially inhibited splenocyte proliferation as compared with non- or mono-ortho-substituted congeners.

However, mixtures of non- and mono-ortho-substituted congeners and multi-ortho-substituted congeners inhibited LPS-induced splenocyte proliferation and antibody secretion at similar concentrations. Exposure of splenocytes to these mixtures did not activate the aryl hydrocarbon receptor AhR signal transduction pathway. These results suggest individual multi-ortho-substituted congeners preferentially inhibit LPS-induced splenocyte proliferation, while congeners not exhibiting an effect individually may have additive effects in a mixture to produce an immunotoxic response through an AhR-independent pathway.

Tropical Journal of Pharmaceutical Research August ; 10 4 : Therefore, we Sulforaphane SFN is a natural product with cytoprotective, anti-inflammatory, and antioxidant effects. In this study, we evaluated the mechanisms of its effects on lipopolysaccharide LPS -induced cell death, inflammation, oxidative stress, and polarization in murine microglia.

We found that SFN protects N9 microglial cells upon LPS-induced cell death and suppresses LPS-induced levels of secreted pro-inflammatory cytokines , tumor necrosis factor-alpha, interleukin-1 beta, and interleukin SFN is also a potent inducer of redox sensitive transcription factor, nuclear factor erythroid 2-related factor 2 Nrf2 , which is responsible for the transcription of antioxidant, cytoprotective, and anti-inflammatory genes.

Mox phenotype is a novel microglial phenotype that has roles in oxidative stress responses. Finally, SFN inhibits microglia-mediated neurotoxicity as demonstrated by conditioned medium and co-culture experiments.

In conclusion, SFN exerts protective effects on microglia and modulates the microglial activation state. Fetuin-A induces cytokine expression and suppresses adiponectin production. These states are strongly associated with low-grade inflammation and hypoadiponectinemia. We, therefore, hypothesized that fetuin-A may play a role in the regulation of cytokine expression , the modulation of adipose tissue expression and plasma concentration of the insulin-sensitizing and atheroprotective adipokine adiponectin.

In subjects, plasma levels of fetuin-A, adiponectin and, in a subgroup, the multimeric forms of adiponectin were determined. These effects were accompanied by a decrease in adipose tissue Adipoq mRNA expression and lower circulating adiponectin levels p expression of human in vitro differentiated adipocytes p cytokine expression. These data suggest an important role of fatty liver in the pathophysiology of insulin resistance and. Elias, Elias G. Cytokines and growth factors have biologic effects that could stimulate tumor growth, invasion and angiogenesis.

The incidence of 24 factors was investigated in 25 cultured human melanoma cell lines and in 62 fixed tissues at different stages of the disease. Illustrating the complexity of the milieu of the tumor microenvironment, some of these factors may have to be considered in targeted therapy. Full Text Available Cytokines and growth factors have biologic effects that could stimulate tumor growth, invasion and angiogenesis. Allium cepa L. Full Text Available Objectives. We evaluated the in vitro modulatory effects of Allium cepa L.

RAW Cell viability was determined by alamarBlue and protein assays. Nuclei morphology was analysed by DAPI staining. TRAP assays were performed as follows: p-nitrophenyl phosphate was used to determine the acid phosphatase activity of the osteoclasts and TRAP staining was used to evaluate the number and size of TRAP-positive multinucleated osteoclast cells.

Von Kossa staining was used to measure osteoclast resorptive activity. Cytokine levels were measured on osteoclast precursor cell culture supernatants. Both AcE and Qt did not affect cell viability and significantly reduced osteoclastogenesis compared to control. Tumor invasion is a critical first step in the organismic dissemination of cancer cells and the formation of metastasis in distant organs, the most important prognostic factor and the actual cause of death in most of the cancer patients.

Laser capture microscopy combined with gene expression profiling reveals that the expression of interferon-responsive genes is up-regulated in PDPN- expressing cells at the tumor invasive front, which are exposed to CDpositive inflammatory cells.

The results highlight the induction of tumor cell invasion by the inflammatory cytokine -stimulated expression of PDPN in the outermost cell layers of cervical SCC. The potent vasoconstrictor Endothelin-1 ET-1 is known to be upregulated in the setting of infection, and elicits its effect by binding to the ETA receptor.

Changes at both the level of transcription and translation were observed in uterus and placenta in the ET-1 axis and in pro- and anti-inflammatory cytokines over the course of 12h. We discovered that BQ, when administered 10h post LPS, is capable of increasing production of uterine and placental Interleukin, causing a shift away from the pro-inflammatory state. Our results reinforce the role of ET-1 at the maternal fetal interface and highlight the potential benefit of ETA receptor blockade via the suppression of ET-1, and induction of a Th2 cytokine dominant state.

Periodontitis is a chronic inflammatory disease that leads to destruction of tooth supporting tissues. Porphyromonas gingivalis P. Bee venom BV has been widely used as a traditional medicine for various diseases. Previous studies have demonstrated the anti-inflammatory, anti-bacterial effects of BV.

However, a direct role and cellular mechanism of BV on periodontitis-like human keratinocytes have not been explored. Therefore, we investigated the anti-inflammatory mechanism of BV against P. The anti-inflammatory effect of BV was demonstrated by various molecular biological methods. Furthermore, BV may be a useful treatment to anti-inflammatory therapy for periodontitis. Progesterone modulates the LPS-induced nitric oxide production by a progesterone-receptor independent mechanism.

Genital tract infections caused by Gram-negative bacteria induce miscarriage and are one of the most common complications of human pregnancy. LPS administration to 7-day pregnant mice induces embryo resorption after 24h, with nitric oxide playing a fundamental role in this process.

We have previously shown that progesterone exerts protective effects on the embryo by modulating the inflammatory reaction triggered by LPS. Here we sought to investigate whether the in vivo administration of progesterone modulated the LPS-induced nitric oxide production from peripheral blood mononuclear cells from pregnant and non-pregnant mice. We found that progesterone downregulated LPS-induced nitric oxide production by a progesterone receptor-independent mechanism.

Moreover, our results suggest a possible participation of glucocorticoid receptors in at least some of the anti-inflammatory effects of progesterone. Inflammation causes many diseases that are serious threats to human health. However, the molecular mechanisms underlying regulation of inflammation and inflammasome activation are not fully understood which has delayed the discovery of new anti-inflammatory drugs of urgent clinic need.

Here, we found that the natural compound Teuvincenone F, which was isolated and purified from the stems and leaves of Premna szemaoensis, could significantly inhibit lipopolysaccharide LPS? The present study was performed to investigate the effect of piracetam on neuroinflammation induced by lipopolysaccharide LPS and resulting changes in cognitive behavior.

On ninth day, the behavioral test for memory and anxiety was done followed by blood collection and microdissection of the hippocampus HIP and prefrontal cortex brain regions. Piracetam attenuated the LPS-induced decrease in coping strategy to novel environment indicating anxiolytic activity. It also reversed the LPS-induced changes in the known arm and novel arm entries in the Y-maze test indicating amelioration of spatial memory impairment.

It ameliorated changes in hippocampal lipid peroxidation and nitrite levels including the activity of superoxide dismutase. Therefore, the present study indicates preclinical evidence for the use of piracetam in the treatment of neuroinflammatory disorders.

Endogenous prostaglandin I 2 PGI 2 has inhibitory effects on immune responses against pathogens or allergens; however, the immunomodulatory activity of endogenous PGI 2 signaling in endotoxin-induced inflammation is unknown. These results indicated that endogenous PGI 2 signaling attenuated neutrophilic lung inflammation through the reduced inflammatory cytokine and chemokine and enhanced IL The effect of melatonin from slow-release implants on basic and TLRmediated gene expression of inflammatory cytokines and their receptors in the choroid plexus in ewes.

Under basal conditions, we observed weak expression of Tnf, low expression of Il1B, Il6 and Il1r2 and intermediate expression of other cytokines receptors. This indicates that melatonin from slow-release implants suppresses TLR4-mediated Il6 expression in the ovine CP via a mechanism likely involving clock genes. Mechanical ventilation with high tidal volumes attenuates myocardial dysfunction by decreasing cardiac edema in a rat model of LPS-induced peritonitis.

During sepsis, myocardial dysfunction is common and increased endothelial activation and permeability can cause myocardial edema, which may, among other factors, hamper myocardial function. We investigated the effects of MV with injuriously high tidal volumes on the myocardium in an animal model of sepsis. Methods Normal rats and intraperitoneal i. Non-ventilated animals served as controls. Ex vivo myocardial function was measured in isolated Langendorff-perfused hearts.

Cardiac expression of endothelial vascular cell adhesion molecule VCAM-1 and edema were measured to evaluate endothelial inflammation and leakage. LPS-induced peritonitis decreased myocardial function ex vivo but MV attenuated systolic dysfunction Vt-dependently. Cardiac edema was lowered Vt-dependently by MV, particularly after LPS, and correlated inversely with systolic myocardial function parameters ex vivo. This was associated with a reduction in cardiac edema following a lower transmural coronary venous outflow pressure during LPS-induced coronary inflammation.

To identify possible disease-specific characteristics of subjects with periodontitis relative to subjects with chronic There were a few similarities among disease groups Inhibition of LPS binding to MD-2 co-receptor for suppressing TLR4-mediated expression of inflammatory cytokine by 1-dehydrogingerdione from dietary ginger.

Here, we delineated a new mechanism of 1-dehydrogingerdione 1D10G , one of pungent isolates from ginger Zingiber officinale , in the suppression of lipopolysaccharide LPS -induced gene expression of inflammatory cytokines.

Taken together, MD-2 is a molecular target in the anti-inflammatory action of 1D10G. Full Text Available Zonulin protein is a newly discovered modulator which modulates the permeability of the intestinal epithelial barrier by disassembling intercellular tight junctions TJ. It has been shown bifidobacterium could protect the intestinal barrier function and prophylactical administration of bifidobacterium has beneficial effects in NEC patients and animals.

However, it is still unknown whether the zonulin is involved in the gut barrier dysfunction of NEC, and the protective mechanisms of bifidobacterium on intestinal barrier function are also not well understood. The present study aims to investigate the effects of bifidobacterium on intestinal barrier function, zonulin regulation, and TJ integrity both in LPS-induced enterocyte barrier injury of Caco-2 monolayers and in a rat NEC model.

Our results showed bifidobacterium markedly attenuated the decrease in transepithelial electrical resistance and the increase in paracellular permeability in the Caco-2 monolayers treated with LPS P expression P expression and localization of TJ proteins in the ileum compared with animals with NEC. We concluded that bifidobacterium may. Modulation of cytokine expression in human macrophages by endocrine-disrupting chemical Bisphenol-A. In the present study, the effects of BPA on the cytokines responses of human macrophages were investigated.

Our results indicated that BPA effected inflammatory responses of macrophages via modulating of cytokines expression , and provided a new insight into the link between exposure to BPA and human health. Overall, our data indicate that quince peel polyphenolic extract induces a potent anti-inflammatory effect that may prove useful for the treatment of inflammatory diseases and that a quince. Macrophages activated by microbial lipopolysaccharides LPS produce bursts of nitric oxide and reactive oxygen species ROS.

Redox protection systems are essential for the survival of the macrophages since the nitric oxide and ROS can be toxic to them as well as to pathogens. We propose that the induction of IDPc is one of the main self-protection mechanisms of macrophages against LPS-induced oxidative stress. Attenuated effects of chitosan-capped gold nanoparticles on LPS-induced toxicity in laboratory rats.

The impact of nanoparticles in medicine and biology has increased rapidly in recent years. Gold nanoparticles AuNP have advantageous properties such as chemical stability, high electron density and affinity to biomolecules. However, the effects of AuNP on human body after repeated administration are still unclear. Therefore, the purpose of the present study was to evaluate the effects of gold Our results suggest that the smaller size of chitosan-capped AuNP shows the protective effects against LPS-induced toxicity, suggesting a very high potential for biomedical applications.

HMGB in mollusk Crassostrea ariakensis Gould: structure, pro-inflammatory cytokine function characterization and anti-infection role of its antibody. Prevention and control of this disease is a priority for the development of oyster aquaculture. It has been proven that mammalian HMGB high mobility group box can be released extracellularly and acts as an important pro-inflammatory cytokine and late mediator of inflammatory reactions. Indirect immunofluorescence study revealed that Ca-HMGB localized both in the hemocyte nucleus and cytoplasm before RLO challenge, but mainly in the cytoplasm 12 h after challenge.

Lignans from Arctium lappa and their inhibition of LPS-induced nitric oxide production. A new butyrolactone sesquilignan, isolappaol C 1 , together with four known lignans, lappaol C 2 , lappaol D 3 , lappaol F 4 , and diarctigenin 5 , were isolated from the methanolic extract of the seeds from the Arctium lappa plant.

All the isolates were evaluated for their inhibitory effects on the LPS-induced nitric oxide production using murine macrophage RAW Caffeoyl glucosides from Nandina domestica inhibit LPS-induced endothelial inflammatory responses.

Endothelial dysfunction is a key pathological feature of many inflammatory diseases, including sepsis. In the present study, a new caffeoyl glucoside 1 and two known caffeoylated compounds 2 and 3 were isolated from the fruits of Nandina domestica Thunb. The compounds were investigated for their effects against lipopolysaccharide LPS -mediated endothelial inflammatory responses.

A number of autophagosomes were also observed under electron microscopy. Furthermore, TSS treatment could effectively upregulate LPS-induced decrease of autophagy levels, as evidenced by the increased expression of LC3 and Beclin-1, and more autophagosomes. The protective effect of TSS on LPS-induced small intestinal injury may be attributed to the inhibition of inflammatory factors and promotion of autophagy levels. The present study may provide novel insight into the molecular mechanisms of TSS on the treatment of intestinal injury.

Cytokine and acute phase protein gene expression in liver biopsies from dairy cows with a lipopolysaccharide - induced mastitis. A minimally invasive liver biopsy technique was tested for its applicability to study the hepatic acute phase response APR in dairy cows with Escherichia coli lipopolysaccharide LPS -induced mastitis.

Lipopolysaccharide-induced mastitis resulted in a time-dependent production of inflammatory cytokines and SAA and Hp in the liver of dairy cows Glycolipids are the major constituent of the thylakoid membrane of higher plants and have a variety of biological and pharmacological activities. However, anti-inflammatory effects of glycolipids on vascular endothelial cells have not been elucidated. Here, we investigated the effect of glycolipids extracted from spinach on lipopolysaccharides LPS -induced endothelial inflammation and evaluated the underlying molecular mechanisms.

These findings suggest that glycolipids from spinach may have a potential therapeutic use for inflammatory vascular diseases. In the present study, the chroman KL compound was found to inhibit lipopolysaccharide LPS -induced nitric oxide production in macrophages RAW Systemic administration of nt-pTMD showed a significant therapeutic effect on LPS-induced sepsis model by inhibiting pro-inflammatory cytokines secretion. Therefore, nt-pTMD can be a novel therapeutics for the treatment of various inflammatory diseases, including sepsis, where a transcription factor has a key role in pathogenesis, and further allows us to discover new functions of p65 under normal physiological condition without genetic alteration.

Full Text Available Berberine hydrochloride is an isoquinoline type alkaloid extracted from Berberidaceae, Rutaceae, and other plants. Previous reports have shown that berberine hydrochloride has anti-inflammatory properties. However, the underlying molecular mechanisms remain unclear. In this study, a lipopolysaccharide- LPS - induced murine model of mastitis was established to explore the anti-inflammatory action of berberine hydrochloride. The pathological and histopathological changes of the mammary glands were observed.

Berberine hydrochloride is an isoquinoline type alkaloid extracted from Berberidaceae, Rutaceae, and other plants. Cytokine gene expression of peripheral blood lymphocytes Mar 20, Key words: Lipopolysaccharide, lymphocytes, TLRs, cytokines.

Lipopolysaccharide LPS , a predominant glycolipid in the outer membranes of Gam-negative bacteria, stimulates monocyte, macrophages, and neutrophils and increase expression of cell adhesion molecules Trent et al. Ilexgenin A, a novel pentacyclic triterpenoid extracted from Aquifoliaceae shows reduction of LPS-induced peritonitis in mice. Ilexgenin A IA is a novel pentacyclic triterpenoid, which extracted from leaves of Ilex hainanensis Merr.

In the present study, we aim to explore anti-inflammatory activity of IA on LPS-induced peritonitis and its underlying molecular mechanism. The results determined that IA was capable of suppressing peritonitis in mice induced by intraperitoneal i.

Furthermore, the results showed that IA dramatically inhibited levels of inflammatory cells infiltration in peritoneal cavity and serum in LPS-induced mice peritonitis model. These results demonstrated that IA might as an anti-inflammatory agent candidate for inflammatory disease therapy. A central role for the mammalian target of rapamycin in LPS-induced anorexia in mice. Bacterial lipopolysaccharide LPS , also known as endotoxin, induces profound anorexia. However, the LPS-provoked pro-inflammatory signaling cascades and the neural mechanisms underlying the development of anorexia are not clear.

Mammalian target of rapamycin mTOR is a key regulator of metabolism, cell growth, and protein synthesis. These results suggest promising approaches for the prevention and treatment of LPS-induced anorexia. Full Text Available Stem cell therapy for tissue regeneration has several limitations in the fact that transplanted cells could not survive for a long time. For solving these limitations, many studies have focused on the antioxidants to increase survival rate of neural stem cells NSCs.

Melatonin, an antioxidant synthesized in the pineal gland, plays multiple roles in various physiological mechanisms. Melatonin exerts neuroprotective effects in the central nervous system. To determine the effect of melatonin on NSCs which is in LPS-induced inflammatory stress state, we first investigated nitric oxide NO production and cytotoxicity using Griess reagent assays, LDH assay, and neurosphere counting.

Based on our results, we conclude that melatonin may be an important factor for the survival and proliferation of NSCs in neuroinflammatory diseases. The main active component is alliin S-allyl cysteine sulfoxide, a potent antioxidant with cardioprotective and neuroprotective actions.

In addition, it helps to decrease serum levels of glucose, insulin, triglycerides, and uric acid, as well as insulin resistance, and reduces cytokine levels. However its potential anti-inflammatory effect is unknown. Furthermore, the gene expression profile by microarrays evidentiate an upregulation of genes involved in immune response and downregulation of genes related with cancer.

The present results have shown that alliin is able to suppress the LPS inflammatory signals by generating an anti-inflammatory gene expression profile and by modifying adipocyte metabolic profile. Xanthohumol Xn, a principal prenylflavonoid, possesses anti-inflammation and anti-oxidant activities. Accordingly, we focused on exploring the protective effect of Xn in the context of ALI and the involvement of underlying molecular mechanisms.

Keywords: Xanthohumol, Acute lung injury, Oxidative stress. DNA methylcytosine dioxygenase ten-eleven translocation 2 enhances lipopolysaccharide-induced cytokine expression in human dental pulp cells by regulating MyD88 hydroxymethylation. Ten-eleven translocation 2 TET2 is a recently discovered DNA methylcytosine dioxygenase that plays important roles in inflammatory disease.

However, its role in the inflammatory response of dental pulp is unknown. Thus, TET2-dependent DNA demethylation might play an important role in dental pulp inflammation as an epigenetic regulator. Post translational modifications, ubiquitination and its reversal by deubiquitination play an important role in regulating innate immune system.

USP12 is a poorly studied deubiquitinase reported to regulate T-cell receptor signalling however the functional role of USP12 in macrophages, the principal architects of inflammation, is unknown. Thus, in this study we probed the involvement of USP12 in macrophage mediated inflammatory responses using bacterial endotoxin, LPS, as the model system.

The potent vasoconstrictor Endothelin-1 ET-1 is known to be upregulated in the setting of infection, and elicits its effect by binding to the ET A receptor. We hypothesize that the administration of BQ post LPS exposure will dismantle a positive feedback loop observed with pro-inflammatory cytokines upstream of ET On GD Changes at both the level of transcription and translation were observed in uterus and placenta in the ET-1 axis and in pro- and anti-inflammatory cytokines over the course of 12 h.

We discovered that BQ, when administered 10 h post LPS, is capable of increasing production of uterine and placental Interleukin, causing a shift away from the pro-inflammatory state. Our results reinforce the role of ET-1 at the maternal fetal interface and highlight the potential benefit of ET A receptor blockade via the suppression of ET-1, and induction of a Th2 cytokine dominant state. However, no studies have examined whether andrographolide And reduces LPS-induced myocardial malfunction.

Methods: Left ventricular systolic and diastolic functions were examined using echocardiography. NO oxidation products were determined using Griess reagent. Oxidative injury was determined by measuring myocardial lipid peroxidation and superoxide dismutase activity. Results: And blunted LPS-induced myocardial malfunctions in mice. Cardiac apoptosis was attenuated via incubation with And, but the extent of oxidative injury remained unaffected. Full Text Available The iridoids of Hedyotis diffusa Willd play an important role in the anti-inflammatory process, but the specific iridoid with anti-inflammatory effect and its mechanism has not be thoroughly studied.

An iridoid compound named scandoside SCA was isolated from H. Its anti-inflammatory mechanism was confirmed by in intro experiments and molecular docking analyses. LPS-induced systemic inflammation is more severe in P2Y12 null mice. Thienopyridines are a class of antiplatelet drugs that are metabolized in the liver to several metabolites, of which only one active metabolite can irreversibly antagonize the platelet P2Y12 receptor.

Possible effects of these drugs and the role of activated platelets in inflammatory responses have also been investigated in a variety of animal models, demonstrating that thienopyridines could alter inflammation. However, it is not clear whether it is caused only by the P2Y12 antagonism or whether off-target effects of other metabolites also intervene. To address this question, we investigated P2Y12 KO mice during a LPS-induced model of systemic inflammation, and we treated these KO mice with a thienopyridine drug clopidogrel.

Contrary to the reported effects of clopidogrel, numbers of circulating WBCs and plasma levels of cytokines were increased in LPS-exposed KO mice compared with WT in this inflammation model. Moreover, both spleen and bone marrow show an increase in cell content, suggesting a role for P2Y12 in regulation of bone marrow and spleen cellular composition.

Finally, the injury was more severe in the lungs of KO mice compared with WT. Interestingly, clopidogrel treatments also exerted protective effects in KO mice, suggesting off-target effects for this drug. In conclusion, the P2Y12 receptor plays an important role during LPS-induced inflammation, and this signaling pathway may be involved in regulating cell content in spleen and bone marrow during LPS systemic inflammation.

Furthermore, clopidogrel may have effects that are independent of P2Y12 receptor blockade. Full Text Available The ocean is a rich resource of flora, fauna, food, and biological products. We found a wild-type bacterial strain, Pseudoalteromonas sp. M2, from marine water and isolated various secondary metabolites. Pseudane-VII is a compound isolated from the Pseudoalteromonas sp.

M2 metabolite that possesses anti-melanogenic activity. Inflammation is a response of the innate immune system to microbial infections. Macrophages have a critical role in fighting microbial infections and inflammation. Recent studies reported that various compounds derived from natural products can regulate immune responses including inflammation. However, the anti-inflammatory effects and mechanism of pseudane-VII in macrophages are still unknown.

In this study, we investigated the anti-inflammatory effects of pseudane-VII. These findings may provide new approaches in the effort to develop anti-inflammatory therapeutics. The ocean is a rich resource of flora, fauna, food, and biological products. Sepsis-induced cardiac apoptosis is one of the major pathogenic factors in myocardial dysfunction. As it enhances numerous proinflammatory factors, lipopolysaccharide LPS is considered the principal mediator in this pathological process.

However, the detailed mechanisms involved are unclear. In this study, we attempted to explore the mechanisms involved in LPS-induced cardiomyocyte apoptosis. Overexpression of miR protected the cardiomyocytes against LPS-induced apoptosis. The effect of tuna eyeball oil TEO on lipopolysaccharide LPS -induced inflammation in macrophage cells was investigated.

The rate of formation of ear edema was reduced compared to that in the control at the highest dose tested. These results suggested that TEO may have a significant effect on inflammatory factors and be a potential anti-inflammatory therapeutic. Synthesis and optimization of novel allylated mono-carbonyl analogs of curcumin MACs act as potent anti-inflammatory agents against LPS-induced acute lung injury ALI in rats.

Most of the obtained compounds exhibited improved water solubility as a hydrochloride salt compared to lead molecule 8f. These results suggest that 7a could be therapeutically beneficial for use as an anti-inflammatory agent in the clinical treatment of acute lung injury ALI. Human umbilical cord mesenchymal stem cells reduce systemic inflammation and attenuate LPS-induced acute lung injury in rats. Full Text Available Abstract Background Mesenchymal stem cells MSCs possess potent immunomodulatory properties and simultaneously lack the ability to illicit immune responses.

Hence, MSCs have emerged as a promising candidate for cellular therapeutics for inflammatory diseases. Within the context of this study, we investigated whether human umbilical cord-derived mesenchymal stem cells UC-MSCs could ameliorate lipopolysaccharide- LPS - induced acute lung injury ALI in a rat model. The rats were sacrificed at 6, 24, and 48 hours after injection.

Serum, bronchoalveolar lavage fluid BALF, and lungs were collected for cytokine concentration measurements, assessment of lung injury, and histology. Conclusion UC-MSCs noticeably increased the survival rate of rats suffering from LPS-induced lung injury and significantly reduced systemic and pulmonary inflammation.

Promoting anti-inflammatory homeostasis and reducing oxidative stress might be the therapeutic basis of UC-MSCs. Olgun, Nicole S. The purpose of our investigation was designed to reveal the effect of andrographolide on various aspects of LPS induced inflammation in vivo and in vitro. These results suggest andrographolide may be considered as an effective and safe drug for the potential treatment of ALI.

This study explored the effect of miRb on inflammatory injury in chondrogenic cells. Full Text Available The fruit hull of Gleditsia sinensis FGS has been prescribed as a traditional eastern Asian medicinal remedy for the treatment of various respiratory diseases, but the efficacy and underlying mechanisms remain poorly characterized.

Here, we explored a potential usage of FGS for the treatment of acute lung injury ALI, a highly fatal inflammatory lung disease that urgently needs effective therapeutics, and investigated a mechanism for the anti-inflammatory activity of FGS. These results suggest that FGS effectively suppresses neutrophilic lung inflammation, which can be associated with, at least in part, FGS-activating anti-inflammatory factor Nrf2.

Full Text Available Background: Sickle cell anaemia is an inherited disease in which the red blood cells become rigid and sticky, and change from being disc-shaped to being crescent-shaped. The change in shape is due to the presence of an abnormal form of haemoglobin. This results in severe pain and damage to some organs. Aim and Objective: The study was carried out to determine the levels of cytokine in sickle cell anemia. Material and Methods: Thirty confirmed sickle cell patients in steady state HbSS-SS and thirty persons with normal haemoglobin HbAA as well as sixteen sickle cell disease in crises HbSS-cr between the ages of 15 to 30 years were selected in this study.

Also, cytokines could be used as an inflammatory marker as well as related marker in disease severity and hence therapeutic intervention. Hence, MAT provides higher safety since it evidences an unwanted biological response, which is not completely controlled and is overlooked by the RPT. Sepsis, a clinical syndrome occurring in patients following infection or injury, is a leading cause of mortality worldwide.

It involves uncontrolled inflammatory response resulting in multi-organ failure and even death. Isoalantolactone IAL , a sesquiterpene lactone, is known for its anti-cancer effects. Taken together, our data suggest that IAL may represent a potentially new drug candidate for the treatment of sepsis.

Caspase-8 regulates the expression of pro- and anti-inflammatory cytokines in human bone marrow-derived mesenchymal stromal cells. Mesenchymal stem cells, also called mesenchymal stromal cells, MSCs, have great potential in stem cell therapy partly due to their immunosuppressive properties. How these cells respond to chronic inflammatory stimuli is therefore of importance. Toll-like receptors TLR s are innate immune receptors that mediate inflammatory signals in response to infection, stress, and damage.

Here we investigated the role of caspase-8 in regulating TLR-induced cytokine production from human bone marrow-derived mesenchymal stromal cells hBMSCs. Caspase-8 was also inhibited using a caspase-8 inhibitor, z-IEDT. Caspase-8 appears to modulate hBMSCs into gaining a pro-inflammatory phenotype.

Therefore, inhibiting caspase-8 in hBMSCs might promote an immunosuppressive phenotype which could be useful in clinical applications to treat inflammatory disorders. Moen, Siv H. Abstract Introduction Mesenchymal stem cells, also called mesenchymal stromal cells, MSCs, have great potential in stem cell therapy partly due to their immunosuppressive properties.

Full Text Available The Chilean strawberry fruit has high content of antioxidants and polyphenols. Previous studies evidenced antioxidant properties by in vitro methods. However, the antioxidant effect and its impact as functional food on animal health have not been evaluated. Transaminases and histological studies revealed a reduction in liver injury in rats fed with strawberry aqueous extract compared with the control group.

Altogether, the evidence suggests that dietary supplementation of rats with a Chilean white strawberry aqueous extract favours the normalization of oxidative and inflammatory responses after a liver injury induced by LPS. The Chilean strawberry fruit has high content of antioxidants and polyphenols.

Sepsis, the systemic inflammatory response syndrome SIRS with infection is one of the leading causes of death in critically ill patients in the developed world due to the lack of effective antisepsis treatments. Full Text Available Abstract Background The resolution of inflammatory responses in the lung has not been described in detail and the role of specific cytokines influencing the resolution process is largely unknown. We documented the inflammatory cell types and cytokines found in the bronchoalveolar lavage fluid BALF, and epithelial changes in the axial airway and investigated whether IL may play a role in the resolution process by reducing its levels with anti-IL antibodies.

Results Three major stages of inflammation and resolution were observed in the BALF during the resolution. The first stage was characterized by PMNs that increased over 3 h to 1 d and decreased to background levels by d 6—8. The second stage of inflammation was characterized by macrophage influx reaching maximum numbers at d 6 and decreasing to background levels by d A third stage of inflammation was observed for lymphocytes which were elevated over d 3—6.

Interestingly, IL and IL-9 levels in the BALF showed a cyclic pattern with peak levels at d 4, 8, and 16 while decreasing to background levels at d 1—2, 6, and Depletion of IL caused decreased PMN numbers at d 2, but no changes in inflammatory cell number or type at later time points. Conclusion These data suggest that IL plays a role in enhancing the LPS-induced neutrophilic inflammation of the lung, but does not affect the resolution of inflammation.

Fisetin administration improves LPS-induced acute otitis media in mouse in vivo. Acute otitis media is one of the most common infectious diseases worldwide in spite of the widespread vaccination. The present study was conducted to explore the effects of fisetin on mouse acute otitis media models. The animal models were established by lipopolysaccharide LPS injection into the middle ear of mice via the tympanic membrane. Fisetin was administered to mice for ten days through intragastric administration immediate after LPS application.

Fisetin reduced mucosal thickness caused by LPS. Brain microvascular pericytes are immunoactive in culture: cytokine , chemokine, nitric oxide, and LRP-1 expression in response to lipopolysaccharide. Full Text Available Abstract Background Brain microvascular pericytes are important constituents of the neurovascular unit.

These cells are physically the closest cells to the microvascular endothelial cells in brain capillaries. They significantly contribute to the induction and maintenance of the barrier functions of the blood-brain barrier. However, very little is known about their immune activities or their roles in neuroinflammation. Here, we focused on the immunological profile of brain pericytes in culture in the quiescent and immune-challenged state by studying their production of immune mediators such as nitric oxide NO, cytokines , and chemokines.

Methods Supernatants were collected from primary cultures of mouse brain pericytes. Release of nitric oxide NO was measured by the Griess reaction and the level of S-nitrosylation of pericyte proteins measured with a modified "biotin-switch" method. Specific mitogen-activated protein kinase MAPK pathway inhibitors were used to determine involvement of these pathways on NO production.

Cytokines and chemokines were analyzed by multianalyte technology. The expression of both subunits of LRP-1 was analyzed by western blot. Nitrative stress resulted in S-nitrosylation of cellular proteins. Pericyte expressions of both subunits of. Diabetic retinopathy DR , an important complication of diabetes mellitus DM , is not well understood.

This study explores changes in Th1 and Th2 cytokine expression during DR. Cytokines such as tumor necrosis factor-alpha TNF-alpha and interleukin-1beta IL-1beta are assumed to mediate anorexia during bacterial infections. To improve our understanding of the role that these two cytokines serve in mediating infection during anorexia, we investigated the ability of pentoxifylline PTX , a potent inhibitor of TNF-alpha production, to block the anorectic effects of the bacterial products lipopolysaccharide LPS and muramyl dipeptide MDP in rats.

PTX administration also attenuated the tolerance that is normally observed with a second injection of LPS. This is consistent with the hypothesis that TNF-alpha plays a major role in the anorexia associated with bacterial infection. Protection against LPS-induced cartilage inflammation and degradation provided by a biological extract of Mentha spicata. RA has demonstrated significant anti-inflammatory activity in vitro and in small rodents; thus it was hypothesized that this plant would demonstrate significant anti-inflammatory activity in vitro.

The objectives of this study were: a to develop an in vitro extraction procedure which mimics digestion and hepatic metabolism, b to compare anti-inflammatory properties of High-Rosmarinic-Acid Mentha spicata HRAM with wild-type control M. No anti-inflammatory or chondroprotective effects of RA metabolites on cartilage explants were identified. Conclusions Our biological extraction procedure produces. AbstractBackgroundCompelling evidence has implicated neuroinflammation in the pathogenesis of a number of neurodegenerative conditions.

We sought to identify signaling kinases responsible for cytokine production and to delineate the complex interactions which govern time-related responses to lipopolysaccharide LPS. MethodsWe examined the time-related changes in certain signaling events and the release of proinflammatory cytokines from LPS-stimulated co-cultures of astrocytes and microglia isolated from neonatal rats.

Effects of prebiotics on immune system and cytokine expression. Nowadays, use of prebiotics as feed and food additives has received increasing interest because of the beneficial effects of prebiotics on the health of animals and humans. One of the beneficial effects of prebiotics is stimulation of immune system, which can be direct or indirect through increasing population of beneficial microbes or probiotics, especially lactic acid bacteria and bifidobacteria, in the gut.

An important mechanism of action of probiotics and prebiotics, by which they can affect the immune system, is changing the expression of cytokines. The present review tried to summarize the findings of studies that investigated the effects of prebiotics on immune system with focusing on their effects on cytokine expression.

Generally, most of reviewed studies indicated beneficial effects for prebiotics in terms of improving immune system, by increasing the expression of anti-inflammatory cytokines , while reducing the expressions of proinflammatory cytokines. However, most of studies mainly considered the indirect effects of prebiotics on the immune system through changing the composition and population of gut microbiota , and their direct effects still need to be further studied using prebiotics with different degree of polymerization in different hosts.

Full Text Available The unregulated activation of microglia following stroke results in the production of toxic factors that propagate secondary neuronal injury. Salidroside has been shown to exhibit protective effects against neuronal death induced by different insults. However, the molecular mechanisms responsible for the anti-inflammatory activity of salidroside have not been elucidated clearly in microglia.

In the present study, we investigated the molecular mechanism underlying inhibiting LPS-stimulated BV2 microglial cell mobility of salidroside. The protective effect of salidroside was investigated in microglial BV2 cell, subjected to stretch injury. Moreover, transwell migration assay demonstrated that salidroside significantly reduced cell motility.

Our results also indicated that salidroside suppressed LPS-induced chemokines production in a dose-dependent manner, without causing cytotoxicity in BV2 microglial cells. These results suggest that salidroside possesses a potent suppressive effect on cell migration of BV2 microglia and this compound may offer substantial therapeutic potential for treatment of ischemic strokes that are accompanied by microglial activation.

Adrenaline stimulates the proliferation and migration of mesenchymal stem cells towards the LPS-induced lung injury. Bone marrow-derived mesenchymal stem cells BMSCs could modulate inflammation in experimental lung injury. On the other hand, adrenergic receptor agonists could increase DNA synthesis of stem cells. BMSCs were cultured with adrenergic receptor agonists or antagonists.

A preliminary animal experiment was conducted to validate the findings in ex vivo study. Adrenaline-stimulated BMSCs decreased the inflammation of LPS-stimulated macrophages, probably through the expression and secretion of several paracrine factors. Adrenaline reduced the extent of injury in LPS-injured rats. Our data indicate that adrenaline-stimulated BMSCs might contribute to the prevention from acute lung injury through the activation of adrenergic receptors, promotion of proliferation and migration towards injured lung, and modulation of inflammation.

Plasma cytokine expression in adolescent chronic fatigue syndrome. Low-grade systemic inflammation does not appear to be a central part of adolescent CFS pathophysiology. LPS-induced lung inflammation in marmoset monkeys - an acute model for anti-inflammatory drug testing.

Full Text Available Increasing incidence and substantial morbidity and mortality of respiratory diseases requires the development of new human-specific anti-inflammatory and disease-modifying therapeutics. Therefore, new predictive animal models that closely reflect human lung pathology are needed. In the current study, a tiered acute lipopolysaccharide LPS-induced inflammation model was established in marmoset monkeys Callithrix jacchus to reflect crucial features of inflammatory lung diseases.

Firstly, in an ex vivo approach marmoset and, for the purposes of comparison, human precision-cut lung slices PCLS were stimulated with LPS in the presence or absence of the phosphodiesterase-4 PDE4 inhibitor roflumilast. The corticosteroid dexamethasone was used as treatment control. Secondly, in an in vivo approach marmosets were pre-treated with roflumilast or dexamethasone and unilaterally challenged with LPS. This inflammatory response was significantly suppressed by roflumilast and dexamethasone.

The close similarity of marmoset and human lungs regarding LPS-induced inflammation and the significant anti-inflammatory effect of approved pharmaceuticals assess the suitability of marmoset monkeys to serve as a promising model for studying anti-inflammatory drugs. However, administration of INH induces severe hepatic toxicity in some patients. Previously, we establish a rat model of INH hepatotoxicity utilizing the inflammatory stress theory, in which bacterial lipopolysaccharide LPS potentially enhanced INH toxicity.

These enhancing activities ranged between augmenting the inflammatory stress, oxidative stress, alteration of bile acid homeostasis, and CYP2E1 over- expression. Although pre-treatment with dexamethasone DEX helped overcome both inflammatory and oxidative stress which ended-up in alleviation of LPS augmenting effects, but still minor toxicities were being detected, alongside with CYP2E1 over expression.

A wide range of anti-inflammatory chemicals have been used to treat such diseases while presenting high toxicity and numerous side effects. Here, we report the anti-inflammatory effect of a non-toxic, cost-effective natural agent, polyphenolic extract from the Tunisian quince Cydonia oblonga Miller. Concomitantly, quince polyphenols enhanced the level of the anti-inflammatory cytokine IL secreted by LPS-treated macrophages.

Overall, our data indicate that quince peel polyphenolic extract induces a potent anti-inflammatory effect that may prove useful for the treatment of inflammatory diseases and that a quince-rich regimen may help to prevent and improve the treatment of such diseases. Niclosamide 5-chloro-salicyl- 2-chloronitro anilide is an oral anthelmintic drug used for treating intestinal infection of most tapeworms.

Recently, niclosamide was shown to have considerable efficacy against some tumor cell lines, including colorectal, prostate, and breast cancers, and acute myelogenous leukemia. Specifically, the drug was identified as a potent inhibitor of signal transducer and activator of transcription 3 STAT3 , which is associated with osteoclast differentiation and function. Taken together, our results show that niclosamide is effective in suppressing osteoclastogenesis and may be considered as a new and safe therapeutic candidate for the clinical treatment of osteoclast-related diseases such as osteoporosis.

Lipoxin A4 and platelet activating factor are involved in E. Full Text Available CFTR cystic fibrosis transmembrane conductance regulator is expressed by both neutrophils and platelets. Lack of functional CFTR could lead to severe lung infection and inflammation. Traditional medicines that stimulate or modulate the immune system can be used as innovative approaches to treat immunological diseases.

The herbal medicine IMOD has been shown to strongly modulate immune responses in several animal studies as well as in clinical trials. However, little is known. We evaluated the effects of TR6 on lipopolysaccharide-induced mastitis in mice. In vitro, primary mouse mammary epithelial cells and neutrophils were used to investigate the effects of TR6 on LPS-induced inflammatory responses. TR6 may be a promising therapeutic reagent for mastitis treatment. Published by Elsevier B. The facts described above demonstrated that PWM-induced cells have the function of T-helper cells and play more important role in the synergy than LPS-induced cells.

Modulation of LPS induced inflammatory response by Lawsonyl monocyclic terpene from the marine derived Streptomyces sp. Inhibition of LPS-induced splenocyte proliferation by ortho-substituted polychlorinated biphenyl congeners. Polychlorinated biphenyls PCBs are persistent environmental contaminants, and their ubiquitous nature has prompted studies of their potential health hazards. As a result of their lipophilic nature, PCBs accumulate in breast milk and subsequently affect the health of offspring of exposed individuals.

Biological effects of PCBs in animals have mostly been attributed to coplanar congeners, although effects of ortho congeners also have been demonstrated. The immunotoxic endpoints investigated included splenocyte viability, lipopolysaccharide LPS -induced splenocyte proliferation, and LPS-induced antibody secretion. Congeners with multiple ortho chlorines preferentially inhibited splenocyte proliferation as compared with non- or mono-ortho-substituted congeners.

However, mixtures of non- and mono-ortho-substituted congeners and multi-ortho-substituted congeners inhibited LPS-induced splenocyte proliferation and antibody secretion at similar concentrations. Exposure of splenocytes to these mixtures did not activate the aryl hydrocarbon receptor AhR signal transduction pathway.

These results suggest individual multi-ortho-substituted congeners preferentially inhibit LPS-induced splenocyte proliferation, while congeners not exhibiting an effect individually may have additive effects in a mixture to produce an immunotoxic response through an AhR-independent pathway. Tropical Journal of Pharmaceutical Research August ; 10 4 : Therefore, we Sulforaphane SFN is a natural product with cytoprotective, anti-inflammatory, and antioxidant effects.

In this study, we evaluated the mechanisms of its effects on lipopolysaccharide LPS -induced cell death, inflammation, oxidative stress, and polarization in murine microglia. We found that SFN protects N9 microglial cells upon LPS-induced cell death and suppresses LPS-induced levels of secreted pro-inflammatory cytokines , tumor necrosis factor-alpha, interleukin-1 beta, and interleukin SFN is also a potent inducer of redox sensitive transcription factor, nuclear factor erythroid 2-related factor 2 Nrf2 , which is responsible for the transcription of antioxidant, cytoprotective, and anti-inflammatory genes.

Mox phenotype is a novel microglial phenotype that has roles in oxidative stress responses. Finally, SFN inhibits microglia-mediated neurotoxicity as demonstrated by conditioned medium and co-culture experiments. In conclusion, SFN exerts protective effects on microglia and modulates the microglial activation state. Fetuin-A induces cytokine expression and suppresses adiponectin production.

These states are strongly associated with low-grade inflammation and hypoadiponectinemia. We, therefore, hypothesized that fetuin-A may play a role in the regulation of cytokine expression , the modulation of adipose tissue expression and plasma concentration of the insulin-sensitizing and atheroprotective adipokine adiponectin.

In subjects, plasma levels of fetuin-A, adiponectin and, in a subgroup, the multimeric forms of adiponectin were determined. These effects were accompanied by a decrease in adipose tissue Adipoq mRNA expression and lower circulating adiponectin levels p expression of human in vitro differentiated adipocytes p cytokine expression. These data suggest an important role of fatty liver in the pathophysiology of insulin resistance and.

Elias, Elias G. Cytokines and growth factors have biologic effects that could stimulate tumor growth, invasion and angiogenesis. The incidence of 24 factors was investigated in 25 cultured human melanoma cell lines and in 62 fixed tissues at different stages of the disease. Illustrating the complexity of the milieu of the tumor microenvironment, some of these factors may have to be considered in targeted therapy. Full Text Available Cytokines and growth factors have biologic effects that could stimulate tumor growth, invasion and angiogenesis.

Allium cepa L. Full Text Available Objectives. We evaluated the in vitro modulatory effects of Allium cepa L. RAW Cell viability was determined by alamarBlue and protein assays. Nuclei morphology was analysed by DAPI staining. TRAP assays were performed as follows: p-nitrophenyl phosphate was used to determine the acid phosphatase activity of the osteoclasts and TRAP staining was used to evaluate the number and size of TRAP-positive multinucleated osteoclast cells.

Von Kossa staining was used to measure osteoclast resorptive activity. Cytokine levels were measured on osteoclast precursor cell culture supernatants. Both AcE and Qt did not affect cell viability and significantly reduced osteoclastogenesis compared to control.

Tumor invasion is a critical first step in the organismic dissemination of cancer cells and the formation of metastasis in distant organs, the most important prognostic factor and the actual cause of death in most of the cancer patients. Laser capture microscopy combined with gene expression profiling reveals that the expression of interferon-responsive genes is up-regulated in PDPN- expressing cells at the tumor invasive front, which are exposed to CDpositive inflammatory cells.

The results highlight the induction of tumor cell invasion by the inflammatory cytokine -stimulated expression of PDPN in the outermost cell layers of cervical SCC. The potent vasoconstrictor Endothelin-1 ET-1 is known to be upregulated in the setting of infection, and elicits its effect by binding to the ETA receptor.

Changes at both the level of transcription and translation were observed in uterus and placenta in the ET-1 axis and in pro- and anti-inflammatory cytokines over the course of 12h. We discovered that BQ, when administered 10h post LPS, is capable of increasing production of uterine and placental Interleukin, causing a shift away from the pro-inflammatory state. Our results reinforce the role of ET-1 at the maternal fetal interface and highlight the potential benefit of ETA receptor blockade via the suppression of ET-1, and induction of a Th2 cytokine dominant state.

Periodontitis is a chronic inflammatory disease that leads to destruction of tooth supporting tissues. Porphyromonas gingivalis P. Bee venom BV has been widely used as a traditional medicine for various diseases. Previous studies have demonstrated the anti-inflammatory, anti-bacterial effects of BV. However, a direct role and cellular mechanism of BV on periodontitis-like human keratinocytes have not been explored.

Therefore, we investigated the anti-inflammatory mechanism of BV against P. The anti-inflammatory effect of BV was demonstrated by various molecular biological methods. Furthermore, BV may be a useful treatment to anti-inflammatory therapy for periodontitis. Progesterone modulates the LPS-induced nitric oxide production by a progesterone-receptor independent mechanism. Genital tract infections caused by Gram-negative bacteria induce miscarriage and are one of the most common complications of human pregnancy.

LPS administration to 7-day pregnant mice induces embryo resorption after 24h, with nitric oxide playing a fundamental role in this process. We have previously shown that progesterone exerts protective effects on the embryo by modulating the inflammatory reaction triggered by LPS.

Here we sought to investigate whether the in vivo administration of progesterone modulated the LPS-induced nitric oxide production from peripheral blood mononuclear cells from pregnant and non-pregnant mice. We found that progesterone downregulated LPS-induced nitric oxide production by a progesterone receptor-independent mechanism. Moreover, our results suggest a possible participation of glucocorticoid receptors in at least some of the anti-inflammatory effects of progesterone.

Inflammation causes many diseases that are serious threats to human health. However, the molecular mechanisms underlying regulation of inflammation and inflammasome activation are not fully understood which has delayed the discovery of new anti-inflammatory drugs of urgent clinic need. Here, we found that the natural compound Teuvincenone F, which was isolated and purified from the stems and leaves of Premna szemaoensis, could significantly inhibit lipopolysaccharide LPS?

The present study was performed to investigate the effect of piracetam on neuroinflammation induced by lipopolysaccharide LPS and resulting changes in cognitive behavior. On ninth day, the behavioral test for memory and anxiety was done followed by blood collection and microdissection of the hippocampus HIP and prefrontal cortex brain regions. Piracetam attenuated the LPS-induced decrease in coping strategy to novel environment indicating anxiolytic activity.

It also reversed the LPS-induced changes in the known arm and novel arm entries in the Y-maze test indicating amelioration of spatial memory impairment. It ameliorated changes in hippocampal lipid peroxidation and nitrite levels including the activity of superoxide dismutase. Therefore, the present study indicates preclinical evidence for the use of piracetam in the treatment of neuroinflammatory disorders.

Endogenous prostaglandin I 2 PGI 2 has inhibitory effects on immune responses against pathogens or allergens; however, the immunomodulatory activity of endogenous PGI 2 signaling in endotoxin-induced inflammation is unknown. These results indicated that endogenous PGI 2 signaling attenuated neutrophilic lung inflammation through the reduced inflammatory cytokine and chemokine and enhanced IL The effect of melatonin from slow-release implants on basic and TLRmediated gene expression of inflammatory cytokines and their receptors in the choroid plexus in ewes.

Under basal conditions, we observed weak expression of Tnf, low expression of Il1B, Il6 and Il1r2 and intermediate expression of other cytokines receptors. This indicates that melatonin from slow-release implants suppresses TLR4-mediated Il6 expression in the ovine CP via a mechanism likely involving clock genes. Mechanical ventilation with high tidal volumes attenuates myocardial dysfunction by decreasing cardiac edema in a rat model of LPS-induced peritonitis.

During sepsis, myocardial dysfunction is common and increased endothelial activation and permeability can cause myocardial edema, which may, among other factors, hamper myocardial function. We investigated the effects of MV with injuriously high tidal volumes on the myocardium in an animal model of sepsis.

Methods Normal rats and intraperitoneal i. Non-ventilated animals served as controls. Ex vivo myocardial function was measured in isolated Langendorff-perfused hearts. Cardiac expression of endothelial vascular cell adhesion molecule VCAM-1 and edema were measured to evaluate endothelial inflammation and leakage.

LPS-induced peritonitis decreased myocardial function ex vivo but MV attenuated systolic dysfunction Vt-dependently. Cardiac edema was lowered Vt-dependently by MV, particularly after LPS, and correlated inversely with systolic myocardial function parameters ex vivo. This was associated with a reduction in cardiac edema following a lower transmural coronary venous outflow pressure during LPS-induced coronary inflammation.

To identify possible disease-specific characteristics of subjects with periodontitis relative to subjects with chronic There were a few similarities among disease groups Inhibition of LPS binding to MD-2 co-receptor for suppressing TLR4-mediated expression of inflammatory cytokine by 1-dehydrogingerdione from dietary ginger. Here, we delineated a new mechanism of 1-dehydrogingerdione 1D10G , one of pungent isolates from ginger Zingiber officinale , in the suppression of lipopolysaccharide LPS -induced gene expression of inflammatory cytokines.

Taken together, MD-2 is a molecular target in the anti-inflammatory action of 1D10G. Full Text Available Zonulin protein is a newly discovered modulator which modulates the permeability of the intestinal epithelial barrier by disassembling intercellular tight junctions TJ. It has been shown bifidobacterium could protect the intestinal barrier function and prophylactical administration of bifidobacterium has beneficial effects in NEC patients and animals.

However, it is still unknown whether the zonulin is involved in the gut barrier dysfunction of NEC, and the protective mechanisms of bifidobacterium on intestinal barrier function are also not well understood. The present study aims to investigate the effects of bifidobacterium on intestinal barrier function, zonulin regulation, and TJ integrity both in LPS-induced enterocyte barrier injury of Caco-2 monolayers and in a rat NEC model. Our results showed bifidobacterium markedly attenuated the decrease in transepithelial electrical resistance and the increase in paracellular permeability in the Caco-2 monolayers treated with LPS P expression P expression and localization of TJ proteins in the ileum compared with animals with NEC.

We concluded that bifidobacterium may. Modulation of cytokine expression in human macrophages by endocrine-disrupting chemical Bisphenol-A. In the present study, the effects of BPA on the cytokines responses of human macrophages were investigated. Our results indicated that BPA effected inflammatory responses of macrophages via modulating of cytokines expression , and provided a new insight into the link between exposure to BPA and human health.

Overall, our data indicate that quince peel polyphenolic extract induces a potent anti-inflammatory effect that may prove useful for the treatment of inflammatory diseases and that a quince. Macrophages activated by microbial lipopolysaccharides LPS produce bursts of nitric oxide and reactive oxygen species ROS.

Redox protection systems are essential for the survival of the macrophages since the nitric oxide and ROS can be toxic to them as well as to pathogens. We propose that the induction of IDPc is one of the main self-protection mechanisms of macrophages against LPS-induced oxidative stress. Attenuated effects of chitosan-capped gold nanoparticles on LPS-induced toxicity in laboratory rats.

The impact of nanoparticles in medicine and biology has increased rapidly in recent years. Gold nanoparticles AuNP have advantageous properties such as chemical stability, high electron density and affinity to biomolecules. However, the effects of AuNP on human body after repeated administration are still unclear. Therefore, the purpose of the present study was to evaluate the effects of gold Our results suggest that the smaller size of chitosan-capped AuNP shows the protective effects against LPS-induced toxicity, suggesting a very high potential for biomedical applications.

HMGB in mollusk Crassostrea ariakensis Gould: structure, pro-inflammatory cytokine function characterization and anti-infection role of its antibody. Prevention and control of this disease is a priority for the development of oyster aquaculture. It has been proven that mammalian HMGB high mobility group box can be released extracellularly and acts as an important pro-inflammatory cytokine and late mediator of inflammatory reactions.

Indirect immunofluorescence study revealed that Ca-HMGB localized both in the hemocyte nucleus and cytoplasm before RLO challenge, but mainly in the cytoplasm 12 h after challenge. Lignans from Arctium lappa and their inhibition of LPS-induced nitric oxide production. A new butyrolactone sesquilignan, isolappaol C 1 , together with four known lignans, lappaol C 2 , lappaol D 3 , lappaol F 4 , and diarctigenin 5 , were isolated from the methanolic extract of the seeds from the Arctium lappa plant.

All the isolates were evaluated for their inhibitory effects on the LPS-induced nitric oxide production using murine macrophage RAW Caffeoyl glucosides from Nandina domestica inhibit LPS-induced endothelial inflammatory responses. Endothelial dysfunction is a key pathological feature of many inflammatory diseases, including sepsis.

In the present study, a new caffeoyl glucoside 1 and two known caffeoylated compounds 2 and 3 were isolated from the fruits of Nandina domestica Thunb. The compounds were investigated for their effects against lipopolysaccharide LPS -mediated endothelial inflammatory responses. These mice grew normally but exhibited enhanced sensitivity to LPS-induced toxemia, notable for an increase in vascular permeability and apoptosis.

Tumor vasculature in transgenic mice was extensive and disorganized. Impact of training status on LPS-induced acute inflammation in humans. The aim of the present study was to examine the impact of training status on the ability to induce a lipopolysaccharide LPS -induced inflammatory response systemically as well as in skeletal muscle SkM and adipose tissue AT in human subjects.
