Human TNF alpha ELISpot Pair

Target data

The TNF protein, primarily secreted by macrophages, binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It induces cell death in specific tumor cell lines and acts as a potent pyrogen, causing fever directly or by stimulating interleukin-1 secretion. TNF is implicated in cachexia induction and can stimulate cell proliferation and differentiation under certain conditions. It impairs regulatory T-cells (Treg) function in rheumatoid arthritis patients through FOXP3 dephosphorylation, upregulating protein phosphatase 1 (PP1), which dephosphorylates 'Ser-418' of FOXP3, inactivating FOXP3 and leading to defective Treg cells. TNF is a key mediator of cell death in the anticancer effect of BCG-stimulated neutrophils with DIABLO/SMAC mimetic in the RT4v6 bladder cancer cell line. It induces insulin resistance in adipocytes by inhibiting insulin-induced IRS1 tyrosine phosphorylation and glucose uptake. TNF plays a role in angiogenesis by inducing VEGF production with IL1B and IL6. Additionally, the TNF intracellular domain (ICD) form stimulates IL12 production in dendritic cells.
