Multidrug resistance (MDR) is often characterized by the expression of P-glycoprotein (P-gp), a 170-KD ATP-dependent drug efflux protein. Functional P-gp can confer resistance to activate caspase-8 and -3 dependent …
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]. Intrinsic Pathway 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.
WebGranzyme B (GrB) is one of the serine protease granzymes most commonly found in the granules of natural killer cells (NK cells) and cytotoxic T cells.It is secreted by these cells along with the pore forming protein perforin to mediate apoptosis in target cells.. Granzyme B has also been found to be produced by a wide range of non-cytotoxic cells ranging …
