Pig Tumor necrosis factor (TNF/TNFA/TNFSF2) ELISA kit

TNF，全称为肿瘤坏死因子（tumor necrosis factor），是一种由巨噬细胞、T细胞和其他免疫细胞分泌的细胞因子。最新的研究表明，TNF参与调节多种生理和病理过程，包括炎症、免疫调节、细胞凋亡、细胞增殖和肿瘤发生等。目前，TNF在治疗多种自身免疫性疾病和某些肿瘤中已得到广泛应用，并持续吸引着研究者们的关注和研究。

Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It 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. Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance. Plays a role in angiogenesis by inducing VEGF production synergistically with IL1B and IL6.; The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.

23. Survival in the setting of severe, acute trauma/hemorrhagic shock appears to be associated with an immediate increase in serum TNF-alpha. PMID: 20027315
24. These results suggest that TNF-alpha and IL-10, but not IL-6, are involved in the late reparatory phases of the experimental disk lesion. PMID: 19605905
25. Repression of TNF-alpha associated with moderate hypothermia during experimental cardiac surgery is due to inhibition of the mitogen-activated protein kinase p38/activating protein-1 pathway and not to inhibition of NF-kappa B. PMID: 16606437
