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. [7] TNF signaling occurs through two receptors: TNFR1 and TNFR2. See more 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 See more The human TNF gene was cloned in 1985. It maps to chromosome 6p21.3, spans about 3 kilobases and contains 4 exons. The last exon shares similarity with lymphotoxin alpha (LTA, … See more TNF can bind two receptors, TNFR1 (TNF receptor type 1; CD120a; p55/60) and TNFR2 (TNF receptor type 2; CD120b; p75/80). TNFR1 is 55-kDa and TNFR2 is 75-kDa. TNFR1 is … See more TNF was thought to be produced primarily by macrophages, but it is produced also by a broad variety of cell types including lymphoid cells, mast cells, endothelial cells, cardiac myocytes See more The theory of an anti-tumoral response of the immune system in vivo was recognized by the physician Thomas G. Elliot. In 1964, Gale A Granger from the University of California, Irvine, reported a cytotoxic factor produced by lymphocytes and named it See more TNF is primarily produced as a 233-amino acid-long type II transmembrane protein arranged in stable homotrimers. From this membrane-integrated form the soluble homotrimeric cytokine (sTNF) is released via proteolytic cleavage by the metalloprotease … See more This protein may use the morpheein model of allosteric regulation.
