概述

Tumor necrosis factor alpha(TNF-α),also called cachectin,is the best-know member of the TNF-family,which can cause cell death.This protein is produced by neutrophils,activated lymphocytes,macrophages,NK cells,LAK cells,astrocytes endothelial cells,smooth muscle cells and some transformed cells.TNF-α occurs as a secreted,soluble form and as a membrane-anchored form,both of which are biologically active.The naturally-occurring form of TNF-α is glycosylated,but non-glycosylated recombinant TNF-α has comparable biological activity.The biologically active native form of TNF-α is reportedly a trimer.Human and murine TNF-α show approximately 79%homology at the amino acid level and cross-reactivity between the two species.Two types of receptors for TNF-α have been described and virtually all cell types studied show the presence of one or both of these receptor types.
