WebAbstract. In the last several years the major mechanisms by which both cytotoxic T lymphocytes (CTL) and natural killer (NK) cells mediate cell death and apoptosis have … WebPerforin pathway: Cytotoxic T–cells can induce apoptosis of target cells via exocytosis of the perforin/granzyme B system. Granzyme B can activate directly caspases-8 and -9 and effector caspases. Granzyme B induces truncation of Bid, [granzyme B-truncated Bid (gtBid)], which in turn triggers the mitochondrial pathway.
