TUMOR NECROSIS FACTOR ALPHA (TNF-a)
Tumor necrosis factor alpha (TNF, TNFSF2) is an important multifunctional cytokine that regulates inflammation, host defense, immune responses, and apoptosis. TNF exists as a membrane-bound 26kDa, type II integral membrane protein, and a 17kDa soluble homotrimeric TNF that is generated via proteolytic cleavage by TNF-a converting enzyme (TACE, ADAM17). Both the membrane-bound and soluble forms ...
متن کاملEvaluation of Tumor Necrosis Factor Alpha Polymorphism Frequencies in Endometriosis
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...
متن کاملThe Effect of Aerobic Training on Tumor Necrosis Factor alpha, Hypoxia-Inducible Factor-1 alpha & Vascular Endothelial Growth Factor Gene Expression in Cardiac Tissue of Diabetic Rats
Objective: The goal of this research was to determine the influence of 4 weeks aerobic training on gene expression of tumor necrosis factor alpha (TNF-α), hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in the cardiac tissue of diabetic rats. Materials and Methods: In an experimental study, 30 male wistar rats were partitioned into three groups (n=10), d...
متن کاملTumor necrosis factor (TNF)-alpha induces leptin production through the p55 TNF receptor.
Tumor necrosis factor (TNF)-alpha acts directly on adipocytes to increase production of the lipostatic factor, leptin. However, which TNF receptor (TNFR) mediates this response is not known. To answer this question, leptin was measured in plasma of wild-type (WT), p55, and p75 TNFR knockout (KO) mice injected intraperitoneally with murine TNF-alpha and in supernatants from cultured WT, p55, and...
متن کاملThe paradoxical effect of tumor necrosis factor alpha (TNF-alpha) in endotoxin-induced uveitis.
PURPOSE To investigate the role of TNF-alpha in endotoxin-induced uveitis (EIU) in mice. METHODS To neutralize TNF-alpha activity, mice were pretreated with either repeated injections of this cytokine or a single injection of antibody against it. The mice were then injected intraperitoneally with 500 micrograms endotoxin, to induce lethal septic shock, or into the footpad with 200 micrograms ...
