Caspase-8 has two opposing biological functions - it promotes cell death by triggering the extrinsic pathway of apoptosis, but also has a survival activity, as it is required for embryonic development, T lymphocyte activation, and resistance to necrosis induced by Tumor Necrosis Factor-α (TNF) and related family ligands. Here we show that development of caspase-8-deficient mice is completely rescued by ablation of Receptor Interacting Protein Kinase-3 (RIPK3). Adult animals lacking both caspase-8 and RIPK3 display a progressive lymphoaccumulative disease resembling that seen with defects in CD95 or CD95-ligand, and resist the lethal effects of CD95 ligation in vivo. We have found that caspase-8 prevents RIPK3-dependent necrosis without inducing apoptosis by functioning in a proteolytically active complex with FLICE-Like Inhibitory Protein Long (FLIPL), and this complex is required for the protective function.
