Activated microglia, involved in the occurrence and improvement of sepsis-associated encephalopathy, can induce the expression of pro-inflammatory cytokines and pro-inflammatory enzymes, resulting in inflammation-mediated neuronal cell death. It was reported that propofol could inhibit lipopolysaccharide (LPS) induced pro-inflammatory cytokine and pro-inflammatory enzyme expression in BV2 and p...

Influenza virus infection of the respiratory tract is characterized by a neutrophil infiltrate accompanied by inflammatory cytokine and chemokine production. We and others have reported that Toll-like receptor (TLR) proteins are present on human neutrophils and that granulocyte-macrophage colony-stimulating factor (GM-CSF) treatment enhances IL-8 (CXCL8) secretion in response to stimulation wit...

Infection with the protozoan parasite Entamoeba histolytica results in a high mortality worldwide. To initiate infection, E. histolytica trophozoites in the bowel lumen penetrate the epithelium, and cause extensive lysis of host cells. The acute amebic lesions in animal models are characterized by infiltration with inflammatory cells, particularly neutrophils. The acute host response is likely ...

Cytokine production from peripheral blood mononuclear cells, T-cell subsets and Ia positive monocytes in patients with inflammatory bowel disease were investigated. 26 patients with Crohn's disease (CD), 7 patients with ulcerative colitis (UC) and age and sex matched healthy donors (HD) as controls were studied. No differences were seen between UC and HD in any of the parameters examined. Howev...

Microglial activation results in profound morphological, functional and gene expression changes that affect the pro- and anti-inflammatory mechanisms of these cells. Although statins have beneficial effects on inflammation, they have not been thoroughly investigated for their ability to affect microglial functions. Therefore the effects of rosuvastatin, one of the most commonly prescribed drugs...

Studies of the inflammatory process in the inflamed synovium from rheumatoid arthritis patients have shown an intricate network of molecules involved in its initiation, perpetuation and regulation trial balances the pro- and anti-inflammatory process. This system is self-regulating though the action of anti-inflammatory and pro-inflammatory cytokines cytokine receptor antagonists and naturally ...

Recent studies suggest that pro-inflammatory type M1 macrophages inhibit tumor progression and that anti-inflammatory M2 macrophages enhance it. The aim of this study was to examine the interaction of type M1 and M2 macrophages with pancreatic cancer cells. We studied the migration rate of fluorescein stained pancreatic cancer cells on Matrigel cultured alone or with Granulocyte-Macrophage Colo...

The Suppressors of Cytokine Signalling (SOCS) proteins are negative regulators of cytokine signalling required to prevent excess cellular responses. SOCS1 and SOCS3 are essential to prevent inflammatory disease, SOCS1 by attenuating responses to IFNγ and gamma-common (γc) cytokines, and SOCS3 via regulation of G-CSF and IL-6 signalling. SOCS1 and SOCS3 show significant sequence homology and are...

Lupus nephritis (LN) is a major clinical manifestation of systemic lupus erythematosus (SLE). Although numerous abnormalities of immune system have been proposed, cytokine overexpression plays an essential role in the pathogenesis of LN. In the initial phase of the disease, the immune deposits and/or autoantibodies induce cytokine production in renal resident cells, leading to further inflammat...

Background: Macrophages activation is the important anti-leishmania immune response. Different signals could affect macrophages development and functional activation. Objectives: In the present study, we compared the effect of Leishmania Soluble Antigen (LSA)and Lipopolysaccharide (LPS) on peritoneal macrophage responses. Appropriate activation of macrophages depends on thesignals they receive ...
