Perforin Granzyme Apoptosis Pathway

Perforin/granzyme apoptosis pathway is the primary signaling pathway used by cytotoxic lymphocytes to eliminate virus-infected and/or transformed cells. Studies in gene-disrupted mice indicate that perforin, in combination with granzyme, could induce apoptosis. It is vital for cytotoxic effector function and has an indispensable, but an undefined role in granzyme-mediated apoptosis.
