WebThe Granzyme A and Granzyme B apoptosis pathways are mechanisms by which cell apoptosis is induced. Granzyme A, a tryptase, and Granzyme B, a serine protease, independently activate apoptosis when … WebGranzyme B is crucial for the rapid induction of target cell death by apoptosis, induced by interaction with cytotoxic T cells. The receptor involved in this process has been identified as mannose 6-phosphate receptor which functions as a death receptor for Granzyme B during cytotoxic T cell-induced apoptosis.
WebThe Perforin/Granzyme pathway is mediated by cytotoxic T cells. In this third pathway, apoptosis is induced via either Granzyme B or Granzyme A. All three initiation pathways (apart from Granzyme A) induce cell death through the Execution pathway that involves the activation of caspase-3 [1].
