WebApr 13, 2024 · The major pathways of immune effector cells, including NK92-cells, to mediate cytotoxicity, are the perforin/granzyme and the death-receptor pathway. Detailed knowledge of CAR-effector cells’ cytotoxic mechanisms is essential to unravel resistance mechanisms, which potentially arise by resistance against apoptosis-inducing signaling. WebJan 1, 2002 · Perforin is believed to be principally responsible for the translocation of granzyme B from cytotoxic cells into target cells; the granzyme B then migrates to the target cell nucleus to participate in triggering apoptosis. 4 The roles of perforin in immune regulation still have not been well defined. offset box wrench trinidad

WebPerforin assembles on target membranes, allowing the delivery of granzymes into the target cell. Granzymes are a group of serine proteases that activate caspases, leading to cell death. Direct cell-to-cell contact is … WebPerforin's role in protecting the body against lymphoma was emphasized when scientists discovered that p53 did not have as big of a role in lymphoma surveillance as its counterpart perforin. Perforin and granzymes have been found to have a directly related ability to protect the body against the formation of different kinds of lymphomas.
