Molecular Steps of Tumor Necrosis Factor Receptor-Mediated Apoptosis

[ Vol. 1 , Issue. 3 ]


S. Gupta   Pages 317 - 324 ( 8 )


Until recently it was believed that TNF-induced apoptosis is mediated exclusively by TNF-RI because TNF-RII lacks death domain. However, it has been demonstrated that TNF-RII enhances TNF-RI-mediated apoptosis. In this review, I have discussed the evidence and mechanisms by which TNF-RII regulates TNF-alpha-induced apoptosis. A role of RIP is emphasized and novel mechanisms of FLIP-mediated inhibition of apoptosis are discussed. In addition, various mechanisms of TNF-induced activation of mitochondrial pathway of apoptosis have been reviewed.
