GranzymeAmediatedApoptosisPathway
One mechanism used by cytotoxic T cells to kill tumor cells and virus-infected cells is the release of perforin and granzyme proteins. Perforin proteins form pores in the membranes of the attacked cell, allowing the entry of Granzyme A and Granzyme B. Granzyme B induces caspase activation and cleavage of factors like ICAD, releasing DFF40 to fragment DNA, one of the hallmarks of apoptotic cell death (see Apoptotic DN......阅读全文
