  1. TNF

    Tumor necrosis factor (TNF, cachexin, or cachectin; formerly known as tumor necrosis factor alpha or TNF-α) is an adipokine and a cytokine. TNF is a member of the TNF superfamily, which consists of various transmembrane proteins with a homologous TNF domain. As an adipokine, TNF promotes insulin resistance, and is associated with obesity-induced type 2 diabetes. As a cytokine, TNF is used by the immune system for cell signaling. If macrophages (certain white blood cells) detect an infection, they release TNF to alert other immune system cells as part of an inflammatory response.TNF signaling occurs through two receptors: TNFR1 and TNFR2. TNFR1 is constituitively expressed on most cell types, whereas TNFR2 is restricted primarily to endothelial, epithelial, and subsets of immune cells. TNFR1 signaling tends to be pro-inflammatory and apoptotic, whereas TNFR2 signaling is anti-inflammatory and promotes cell proliferation. Suppression of TNFR1 signaling has been important for treatment of autoimmune disease, whereas TNFR2 signaling promotes wound healing.TNF-α exists as a transmembrane form (mTNF-α) and as a soluble form (sTNF-α). sTNF-α results from enzymatic cleavage of mTNF-α, by a process called substrate presentation. mTNF-α is mainly found on monocytes/macrophages where it interacts with tissue receptors by cell-to-cell contact. sTNF-α selectively binds to TNFR1, whereas mTNF-α binds to both TNFR1 and TNFR2. TNF-α binding to TNFR1 is irreversible, whereas binding to TNFR2 is reversible.The primary role of TNF is in the regulation of immune cells. TNF, as an endogenous pyrogen, is able to induce fever, apoptotic cell death, cachexia, and inflammation, inhibit tumorigenesis and viral replication, and respond to sepsis via IL-1 and IL-6-producing cells. Dysregulation of TNF production has been implicated in a variety of human diseases including Alzheimer's disease, cancer, major depression, psoriasis and inflammatory bowel disease (IBD). Though controversial, some studies have linked depression and IBD to increased levels of TNF.Under the name tasonermin, TNF is used as an immunostimulant drug in the treatment of certain cancers. Drugs that counter the action of TNF are used in the treatment of various inflammatory diseases, for instance rheumatoid arthritis. Certain cancers can cause overproduction of TNF. TNF parallels parathyroid hormone both in causing secondary hypercalcemia and in the cancers with which excessive production is associated.

  1. tnf

    TNF, or Tumor Necrosis Factor, is a cell signaling protein (cytokine) involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction. It is produced chiefly by activated macrophages, although it can be produced by other cell types as well.
