BACKGROUND: Propofol has been shown to attenuate airway hyperresponsiveness in asthma patients. Our previous study showed that it may alleviate lung inflammation in a mouse model of asthma. Given the critical role of T-helper cell type-2 (Th2) differentiation in asthma pathology and the immunomodulatory role of the gamma-aminobutyric acid type A (GABAA) receptor, we hypothesized that propofol could alleviate asthma inflammation by inhibiting Th2 cell differentiation via the GABA receptor...

Innate inflammations are dominant causes of poor health and high mortality. The pathogen-associated molecular pattern and lipopolysaccharide (LPS) are sensed by immune cells through activation of toll-like receptor 4 leading to mitogen-activated protein kinases (MAPKs) and NF-κB activations. Controlled MAPK and Nf-κB inhibitors have been proposed as potential antiinflammatory drugs. Withania somnifera is an important medicinal herb with known antiinflammatory activity. In this study, the selected Withania somnifera extracts and withanolides were analysed on LPS-induced macrophages comparatively...

Microglia are resident macrophage-like immune cells in the central nervous system (CNS) and play a vital role in both physiological and pathological conditions, including restoring the integrity of the CNS and promoting the progression of neurodegenerative disorders. Upon stimulation, microglia typically convert from a surveillant to an activated phenotype. The major function of microglia is to maintain homeostasis and normal function of the CNS, both during development and in response to CNS injury. Microglia regulate multiple aspects of inflammation, such as repair, cytotoxicity, regeneration, and immunosuppression due to their different kind of activation states or phenotypes...

Osteoarthritis (OA) is one of the major joint diseases, and the synovial inflammation is involved in the pathogenesis and progression of OA. Glucosamine (GlcN) is widely used as a dietary supplement for OA, and is expected to exert the antiinflammatory action in OA. However, the detailed mechanism for the antiinflammatory action of GlcN remains poorly understood. In this study, to elucidate the molecular mechanism involved in the GlcN-medicated regulation of synovial cell activation, we comprehensively analyzed the effect of GlcN on the gene expression using a human synovial cell line MH7A by DNA microarray...

BACKGROUND: Statins have antiinflammatory effects at the cardiovascular level because of inhibition of prenylation, which also probably underlies their therapeutic effects in preclinical models of inflammatory bowel disease. Another inhibitor of prenylation, namely alendronate, reduces colitis in rodents. In this study, we aim to explore the therapeutic potential of second-generation, nitrogen-containing bisphosphonates in 3 preclinical models of colitis. METHODS: The trinitrobenzenesulfonic acid and dextran sulfate sodium models of rat colitis and the adoptive lymphocyte transfer model of colitis in mice were used...

The effect of hyperlipidemia on the systemic production of cytokines was evaluated in the plasma of rats after anterior abdominal wall reconstruction with polypropylene (Esfil) and polytetrafluorethylene (Ecoflon) endoprostheses. The reference group was formed from animals without hyperlipidemia, in which anterior abdominal wall plasty was carried out with the use of the same endoprostheses. Intact rats without hyperlipidemia and intervention served as the control. Hypercytokinemia was detected on days 1-10 after reconstructive surgery on the anterior abdominal wall...

The kinetic participation of macrophages is critical for inflammatory resolution and recovery from myocardial infarction (MI), particularly with respect to the transition from the M1 to the M2 phenotype; however, the underlying mechanisms are poorly understood. In this study, we found that the deletion of prostaglandin (PG) D2 receptor subtype 1 (DP1) in macrophages retarded M2 polarization, antiinflammatory cytokine production, and resolution in different inflammatory models, including the MI model. DP1 deletion up-regulated proinflammatory genes expression via JAK2/STAT1 signaling in macrophages, whereas its activation facilitated binding of the separated PKA regulatory IIα subunit (PRKAR2A) to the transmembrane domain of IFN-γ receptor, suppressed JAK2-STAT1 axis-mediated M1 polarization, and promoted resolution...

Immunomodulatory drugs (IMiDs) are a family of compounds derived from thalidomide. Binding of the IMiD molecule to the Lon protease Cereblon initiates the degradation of substrates via the ubiquitin proteasome pathway. Here, we show that Cereblon forms a complex with Rabex-5, a regulator of immune homeostasis. Treatment with lenalidomide prevented the association of Cereblon with Rabex-5. Conversely, mutation of the IMiD binding site increased Cereblon-Rabex-5 coimmunoprecipitation. The thalidomide binding region of Cereblon therefore regulates the formation of this complex...

Chronic nonbacterial osteomyelitis (CNO) is an autoinflammatory bone disorder, covering a clinical spectrum with asymptomatic inflammation of single bones at the one end, and chronic recurrent multifocal osteomyelitis (CRMO) at the other end. The exact molecular pathophysiology of CNO remains largely unknown. Provided familial clusters and the association with inflammatory disorders of the skin and intestine suggest a genetic predisposition. Recently, profound dysregulation of cytokine responses was demonstrated in CRMO...
