Effects of gamma interferon on release of tumor necrosis factor alpha from lipopolysaccharide-tolerant human monocyte-derived macrophages.
After an initial stimulation of human monocyte-derived macrophages with bacterial lipopolysaccharide (LPS), which produces substantial release of tumor necrosis factor-alpha (TNF-alpha), a subsequent exposure to LPS results in about an order-of-magnitude reduction in the levels of TNF-alpha released. We have shown that macrophages which have been stimulated with LPS and then maintained in cultu...
متن کاملPriming of human monocytes for enhanced lipopolysaccharide responses: expression of alpha interferon, interferon regulatory factors, and tumor necrosis factor.
Culture of human monocytes with either granulocyte-macrophage colony-stimulating factor or gamma interferon (IFN-gamma) results in a primed state, during which these cells express heightened responses to bacterial lipopolysaccharide (LPS). The production of IFN-alpha in response to LPS by human monocytes has an absolute requirement for priming. Tumor necrosis factor (TNF) expression is also gre...
متن کاملAlterations in Gene Expression of Interferon and Tumor Necrosis Factor‐α in Human Blood Macrophage-Like Monocytes Induced by Clinical and Standard Salmonella typhi Strains in vitro
Background and Objective: Salmonella typhi as a human pathogen stimulates the human immune system and triggers gene expression changing its pathogenesis. Therefore, we aimed to investigate the expression levels of ifn-γ and tnf-α cytokines in human blood macrophage-like monocytes in dealing with clinical and standard samples of Salmonella typhi in vivo. Materials and Methods: In this cross-sec...
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 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...
