摘要：
Caspase activation is the 'point of no return' commitment to cell death. Synthesized as inactive zymogens, it is essential that the caspases remain inactive until the death signal is received. It is known for the downstream executioner caspases-3 and -7 that the activation event is proteolytic cleavage, and this had been assumed to apply to the initiator caspases as well. However, recent studies conducted on caspases-2, -8 and -9 have challenged this tenet of caspase activation. In this review we focus on the molecular details of caspase activation, with emphasis on recent work that provides a pleasing explanation for the differential requirements for the activation of executioner and initiator caspases.
