Redundant cell death mechanisms as relics and backups

Cell Death Differ. 2005 Nov:12 Suppl 2:1490-6. doi: 10.1038/sj.cdd.4401607.

Abstract

Here we review recent observations indicating the existence of redundant cell death mechanisms. We speculate that this redundancy reflects a particular evolutionary history for cellular demise. Autophagic or apoptotic elements might have been added to a primordial death mechanism, initially improving cell dismantling and later acquiring the ability to act themselves as death effectors. The resulting redundancy of cell death mechanisms has pathophysiological implications.
