Protein Description

Tumor necrosis factor alpha (TNF-α) is an EGF- related polypeptide growth factor that signals through the TNFRSF1A/TNFR1 and TNFRSF1B/ TNFBR. It  is  mainly  secreted by macrophages and also produced by monocytes, keratinocytes, and  various  tumor  cells.  TNF-α   stimulates the proliferation of a wide range  of  epidermal and epithelial cells. TNF-α is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of  cachexia.  Under certain  conditions it can stimulate cell proliferation and induce cell differentiation, impair regulatory T cells (Treg) function in individuals with rheumatoid arthritis via FOXP3 dephosphorylation.
