TNF-alpha, Tumor necrosis factor ligand superfamily member 2, TNF-a, Cachectin, DIF, TNFA, TNFSF2.

Tumor necrosis factor is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is involved in systemic inflammationand secreted mainly by macrophages.
TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesis and viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF’s primary role is in the regulation of immune cells.
Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer.

肿瘤坏死因子是所有刺激急性期反应的一组细胞因子中的一员。 TNF参与全身炎症反应，主要由巨噬细胞分泌。
TNF导致凋亡细胞死亡、细胞增殖、分化、炎症、肿瘤发生和病毒复制，TNF还参与脂质代谢和凝血。 TNF的主要作用是调节免疫细胞。
失调，特别是 TNF 的过度产生与多种人类疾病有关——自身免疫疾病、胰岛素抵抗和癌症。
