Granzyme-mediated apoptotic signaling pathway
WebJan 1, 2015 · Consequently, blocking p53-Bcl-2 interaction decreases GzmB-induced Bax activation, cytochrome c release from mitochondria, and subsequent effector caspases activation leading to a decreased sensitivity of target cells to both GzmB and CTL/NK-mediated cell death. Together, our results define p53 as a new important player in the … WebDec 23, 2004 · nisms. The apoptotic signaling pathways that lead to caspase zymo-gens processing can be subdivided into two major categories: death receptor-mediated and mitochondria-mediated pathways. These apoptotic signals trigger oligomerization of death adaptor proteins (e.g., Apaf-1 or FADD); death adaptor oligomers, in turn, induce
