Background
In addition to functioning as a key initiator caspase for extrinsic apoptosis, more recent studies have identified caspase-8 as a regulator of inflammatory necrotic cell death pathways such as necroptosis and pyroptosis (4,5). Activation of caspase-8 leads to cleavage of RIPK1 and RIPK3 to inhibit necroptosis (6,7). As a result, caspase-8 deficiency in mice, which is embryonic lethal, can be rescued by deletion of the necroptosis proteins RIPK3 or MLKL (8-11). Additionally, in some circumstances, caspase-8 is recruited to the inflammasome to trigger pyroptosis (12,13). Studies have also found that expression of an enzymatically inactive form of caspase-8 (C362S) causes embryonic lethality by inducing necroptosis and pyroptosis (14).
