Mice deficient in caspase-8, FADD, or cFLIP, present defects in yolk sac vascularization and embryonic lethality at E10.5. Ablation of RIPK3, a kinase that promotes a form of necrotic cell death, has recently been shown to rescue embryonic lethality in caspase-8 deficient animals. Here we show that while FADD, RIPK3 double knockouts develop normally, the lethal effects of cFLIP deletion are not rescued by RIPK3 deficiency. Remarkably, embryos lacking FADD, cFLIP, and RIPK3 develop normally. Distinct regions of apoptosis were observed in E9.5 FLIP, RIPK3 double knockout embryos, but not in caspase-8−/− or FADD−/− embryos. In vitro studies using death receptor stimulation show that the FADD-caspase-8-cFLIPL complex blocks RIPK3-dependent necrosis, while cFLIPL blocks RIPK3-independent apoptosis promoted by the FADD-caspase-8 complex. Together, these results suggest the cross-regulation of two distinct processes in development and death-receptor signaling: RIPK3-dependent signaling (including necrosis) controlled by the enzymatic activity of the FADD-caspase-8-cFLIPL complex, and cFLIPL control of RIPK3-independent apoptosis by FADD-caspase-8.
