Evaluation 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 کاملExpression of tumor necrosis factor-alpha--converting enzyme and tumor necrosis factor-alpha in human myocarditis.
OBJECTIVES We determined whether tumor necrosis factor-alpha-converting enzyme (TACE) is expressed with tumor necrosis factor-alpha (TNF-alpha) in myocarditis. BACKGROUND Tumor necrosis factor-alpha-converting enzyme, which has recently been identified as belonging to the family of metalloproteinase disintegrin proteins, is responsible for the conversion of TNF-alpha precursor to its mature f...
متن کاملPriming of phospholipases A2 of human neutrophils by tumor necrosis factor.
99S macrophage represented at least one important source of BAL IL-8 in the patients who subsequently developed ARDS. In established ARDS, both neutrophil chemotaxins were elevated together with MCP-1, but not MIP-ia. These data suggest that different chemotactic cytokines are employed at different stages of the evolution of ARDS. BAL IL-8 may represent a very early marker of the inflammatory r...
متن کاملEffect of tumor necrosis factor-alpha on the metabolism of arachidonic acid in human neutrophils.
Although tumor necrosis factor-alpha (TNF-alpha) has been shown to induce marked changes in the physiology/pathophysiology of cells, little is known about the effects of this cytokine on cellular lipid metabolism. In this study we examined the effects of TNF-alpha on the metabolism of eicosatetraenoic acid (arachidonic acid, (20:4(n-6)) in human neutrophils. Pretreatment of neutrophils with TNF...
متن کاملDivergent effects of tumor necrosis factor alpha on apoptosis of human neutrophils.
Apoptosis of neutrophils is a key mechanism to control the intensity of the acute inflammatory response. Previously, the cytokine tumor necrosis factor alpha (TNF-alpha) was reported by some to have pro-apoptotic and by others to have antiapoptotic effects on neutrophils. The aim of this study was to explain these contradictory results. We found that TNF-alpha at low concentrations strongly dec...
