WebRepresenting the perforin/granzyme pathway of apoptosis. Granzyme B synthesize in CTLs and NK cells transport in target cell through the pore made by perforin protein. Inside the target cell GzmB recruit the caspase 3 and 7 and induce the apoptosis. At the same GzmB can also activate the apoptosis through the mitochondrial mediated pathway. WebThe close relations between them and the possibility of switching from one pathway to another are demonstrated. In most cases, the result of these pathways is mitochondrial membrane permeabilization and/or caspase activation. These two events are closely linked and serve as the central point of integration of the apoptotic cell death pathways.
