The Domains of Apoptosis and Inflammation

Abstract

The tumor necrosis factor receptors (TNFRs) play essential roles in innate and adaptive immunity. Depending on conditions, TNFR induces multiple cell fates including cell survival, cell apoptosis, and cell programmed necrosis. Here, we review recent progress in structural studies of the TNFR signaling pathway. The structural basis for the high order signal complexes, including the DISC, ripoptosome, necrosome, and RIP3/MLKL complex, may provide novel insights for understanding the biophysical principles of cell signaling cascades.
