Confirming a critical role for death receptor 5 and caspase-8 in apoptosis induction by endoplasmic reticulum stress

Abstract

Several studies implicate specific death receptors (DRs) and caspase-8 in mediating apoptosis in response to endoplasmic reticulum (ER) stress; however, a recent paper challenges this conclusion. Here we validate the importance of DR5 and caspase-8 as critical signal conduits for apoptosis activation upon ER stress.
