Chlorogenic acid (CGA), one of the most abundant dietary polyphenolic compounds, has been reported to exhibit anti-inflammatory ability. However, the hepatoprotective effects and molecular mechanisms of CGA on concanavalin A (Con A)-induced hepatitis have not been explored. In the present study, we found that pretreatment with CGA dose-dependently inhibited the elevation of plasma aminotransferases and alleviated hepatic pathological damage as well as hepatocyte apoptosis in Con A-exposed mice. Additionally, CGA markedly suppressed the production of serum tumor necrosis factor (TNF)-α and interferon (IFN)-γ, alleviated the infiltration of hepatic macrophages, neutrophils, and activated CD4(+) T lymphocytes in Con A-primed mice...

Procyanidins are widely found in plants and have anti-inflammatory activities. Procyanidin B2 (PCB2) inhibits production of proinflammatory cytokines in macrophages. However, there has been no study that has attempted to determine the effects of PCB2 gallates on T cell functions. In the present study, murine splenocytes were isolated and treated with PCB2 or PCB2 gallates in the presence of an anti-CD3 monoclonal antibody (mAb). PCB2 gallates, but not PCB2, inhibited proliferation and T cell activation of splenocytes after stimulation with the anti-CD3 mAb...

Systemic inflammation induces transient or permanent dysfunction in the brain by exposing it to soluble inflammatory mediators. The receptor for advanced glycation endproducts (RAGE) binds to distinct ligands mediating and increasing inflammatory processes. In this study we used an LPS-induced systemic inflammation model in rats to investigate the effect of blocking RAGE in serum, liver, cerebrospinal fluid (CSF) and brain (striatum, prefrontal cortex, ventral tegmental area and substantia nigra). Intraperitoneal injection of RAGE antibody (50 μg/kg) was followed after 1h by a single LPS (5 mg/kg) intraperitoneal injection...

Delirium is a frequent outcome for aged and demented patients that suffer a systemic inflammatory insult. Animal models that reconstruct these etiological processes have potential to provide a better understanding of the pathophysiology of delirium. Therefore, we systematically reviewed animal studies in which systemic inflammation was superimposed on aged or diseased animal models. In total, 77 studies were identified. Aged animals were challenged with a bacterial endotoxin in 29 studies, 25 studies superimposed surgery on aged animals, and in 6 studies a bacterial infection, Escherichia coli (E...

For a long time iodine has been used as an active dermal agent in the treatment of inflammatory, immune-mediated and infectious diseases. Moreover, topical iodine application has been reported to provide protection against sulfur-mustard-induced skin lesions, heat-induced and acid-induced skin burns in both haired guinea-pigs and mouse ear swelling models. However, the exact mechanism of action underlying these benefits of iodine has not yet been elucidated. In the current study, a novel mechanism of action by which iodine provides skin protection and relief, based on its electrophilic nature, is suggested...

The CCAAT/Enhancer Binding Protein β (C/EBPβ) transcription factor is activated by multiple inflammatory stimuli, including IL-17 and LPS, and C/EBPβ itself regulates numerous genes involved in inflammation. However, the role of C/EBPβ in driving autoimmunity is not well understood. Here, we demonstrate that Cebpb(-/-) mice are resistant to EAE. Cebpb(-/-) mice exhibited reduced lymphocyte and APC infiltration into CNS following EAE induction. Furthermore, MOG-induced Th17 cytokine production was impaired in draining LN, indicating defects in Th17 cell priming...

Inflammatory bowel disease (IBD) is assumed to be caused by genetic and environmental factors that interact together in promoting intestinal immune dysregulation where cytokines have validated role. However, the underlying intimate mechanisms in the human IBD involving cytokines still needs to be supplemented especially in the clinical context. The aim of this study was to investigate the expression of some inflammatory and regulatory cytokines (IL-17A, IL-23, IL-6, TGFβ1, and IL-10) as well as of the transcription factor FoxP3 in mucosal samples of IBD and non-IBD patients...

The application of the probiotic lactobacillus is suggested in the treatment of some inflammatory diseases of intestines due to its potential ability to attenuate inflammation. However, the mechanism is not completely understood. In PBMCs, Lactobacillus paracasei (L. Paracasei) down-regulated the LPS-induced production of TNF-α and IL-6. Using a macrophage-like differentiated THP-1 cell line induced by PMA, we investigated the effect of L. paracasei on the production of pro-inflammatory cytokines by monocyte-macrophages...

The health benefits of exercise and physical activity (PA) have been well researched and it is widely accepted that PA is crucial for maintaining health. One of the mechanisms by which exercise and PA exert their beneficial effects is through peripheral immune system adaptations. To date, very few studies have looked at the regulation of neuroimmune reactions in response to PA. We studied the effect of voluntary wheel running (VWR) on pro- and anti-inflammatory cytokine levels, patterns of glial cell activation and expression of immune receptors in the brains of female C57BL/6 mice...

Minipump infusions into visual cortex in vivo at the onset of the critical period have revealed that the proinflammatory cytokine leukemia inhibitory factor (LIF) delays the maturation of thalamocortical projection neurons of the lateral geniculate nucleus, and tecto-thalamic projection neurons of the superior colliculus, and cortical layer IV spiny stellates and layer VI pyramidal neurons. Here, we report that P12-20 LIF infusion inhibits somatic maturation of pyramidal neurons and of all interneuron types in vivo...

Nuclear factor κappa B (NF-κB) is an important transcription factor in the development and progression of coronary artery disease (CAD). Recent evidence suggests that -94 ATTG ins/del mutant in the promoter of NFKB1 gene is an essential functional mutant. The present study demonstrated the frequencies of the del/del (DD) genotype and del (D) allele were significantly higher in CAD patients than in controls. CAD patients carrying mutant DD genotype had worse stenosis of diseased coronary arteries compared to those carrying ins/ins (II) or ins/del (ID) genotype...

The surface localized Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) of Streptococcus pneumoniae is best known as housekeeping protein. Currently, GAPDH has been recognized as moonlighting protein and virulent factor. Therefore, we investigate whether GAPDH can act as a suitable vaccine candidate protein to prevent pneumococcal infection. In this study, mice received subcutaneous vaccination with recombinant GAPDH followed by challenge with D39 and 19F showing higher survival rate and lower bacterial loads in nasal washes and lung homogenates than control...

Leprosy triggers a complex relationship between the pathogen and host immune response. Endothelium plays an important role in this immune response by directly influencing cell migration to infected tissues. The objective of this work is to investigate the possible role of endothelium in M. leprae infection, correlating the characteristics of endothelial markers with the expression pattern of cytokines. Thirty-six skin biopsy samples were cut into 5-μm thick sections and stained with hematoxylin-eosin and Ziehl-Neelsen for morphological analysis and then submitted to immunohistochemical analysis using monoclonal antibodies against ICAM-1, ICAM-2, VCAM-1, and VLA-4...

Mastitis is the most common disease in dairy herds worldwide and is often caused by Staphylococcus aureus. Little is known about the effect of mastitis on transporters in the mammary gland and the effect on transporter-mediated secretion of drugs into milk. We studied gene expressions of ATP-binding cassette and solute carrier transporters in S. aureus-infected mammary glands of mice. On d 7 of lactation, NMRI mice were inoculated with 1,000 cfu of S. aureus in 2 mammary glands and with a saline vehicle in 2 control glands...

BACKGROUND: Oxaliplatin, a widely used anticancer drug against metastatic colorectal cancer, can induce acute peripheral neuropathy, which is characterized by cold and mechanical allodynia. Activation of glial cells (e.g. astrocytes and microglia) and increase of pro-inflammatory cytokines (e.g. IL-1β and TNF-α) in the spinal cord play a crucial role in the pathogenesis of neuropathic pain. Our previous study demonstrated that Gyejigachulbu-Tang (GBT), a herbal complex formula, alleviates oxaliplatin-induced neuropathic pain in rats by suppressing spinal glial activation...

Asthma is a phenotypically heterogeneous chronic disease of the airways. Studies have found that neutrophils are crucial to airway inflammation in acute asthma, persistent asthma, particularly in asthma of poor response to glucocorticoid treatment. The role of neutrophils in development of bronchial asthma is complex, as they can release a potent source of cytokines and inflammatory mediators participating in asthma. Differing from eosinophilic inflammatory asthma, neutrophilic inflammatory asthma is not depend on helper T (Th)2 cells, but may be related to Th1 and Th17 cells...
