TNFSF12

Tumor necrosis factor ligand superfamily member 12 also known as TNF-related weak inducer of apoptosis (TWEAK) is a protein that in humans is encoded by the TNFSF12 gene.[4][5][6]

Function

TWEAK was discovered in 1997.[4] The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This protein is a ligand for the FN14/TWEAKR receptor. This cytokine has overlapping signaling functions with TNF, but displays a much wider tissue distribution. Leukocytes are the main source of TWEAK including human resting and activated monocytes, dendritic cells and natural killer cells.[7] TWEAK can induce apoptosis via multiple pathways of cell death in a cell type-specific manner. This cytokine is also found to promote proliferation and migration of endothelial cells, and thus acts as a regulator of angiogenesis.[6]

Clinical significance

Excessive activation of the TWEAK pathway in chronic injury has been described to promote pathological tissue changes including chronic inflammation, fibrosis and angiogenesis.[8] In chronic liver disease, for example, TWEAK expression is enhanced and causes hepatic stellate cells, which are key regulators of liver fibrosis, to proliferate.[9]

gollark: You are to, however.
gollark: I fixed it. You need bracketoids around the pattern.
gollark: Oh yes, it needs brackets. It's valid in my Macron implementation.
gollark: It MIGHT be.
