Mechanisms of CD95 (APO-1/Fas)-mediated apoptosis

This review covers recent advances of CD95 signaling. It focuses on CD95-interacting molecules, formation of the death inducing signaling complex and the role of caspases, particularly caspase-B, and their death substrates. We also discuss the relevance of mitochondria in the CD95-mediated apoptotic process and how viral proteins interfere with crucial steps of this signaling pathway.
