InductionofapoptosisthroughDR3andDR4／5DeathReceptors
Apoptosis is specifically induced via signaling through a family of receptors known collectively as 'death receptors' including Fas, TNFR, DR3, -4 and -5. Death receptor ligands characteristically initiate signaling via receptor oligomerization, recruitment of specialized adaptor proteins and activation of caspase cascades. Apo3L recruits initiator caspase 8 via the adapter protein FADD. Caspase 8 then oligom......阅读全文
