WebGranzyme A, a tryptase, and Granzyme B, a serine protease, independently activate apoptosis when delivered into the target cells with perforin (PFN), a pore-forming protein. Granzyme A activates a caspase-independent death that is morphologically identical to apoptosis, characterized by single-stranded DNA damage, mitochondrial dysfunction, and ...

Perforin is a pore forming cytolytic protein found in the granules of cytotoxic T lymphocytes (CTLs) and natural killer cells (NK cells). Upon degranulation, perforin molecules translocate to the target cell with the help of calreticulin, which works as a chaperone protein to prevent perforin from degrading. Perforin then binds to the target cell's plasma membrane via membrane phospholipids while phosphatidylcholine binds calcium ions to increase perforin's affinity to the membrane. Pe… WebApr 12, 2024 · The enhanced efficacy of Y6V-iIL12 CAR-T cells was further corroborated by profound increase in IFN-γ, TNF-α, perforin, and granzyme B release in mouse sera, presumably caused by IL-12 secretion ...
WebApr 14, 2024 · It is widely assumed that both perforin and granzyme B are necessary for efficient cytotoxicity of T cells. Interestingly, perforin knockout OT-I T cells have been shown to efficiently kill MC38 Ova and B16 Ova cells in prolonged presence (>18 hours) of antigens ( 76 ), indicating cytolytic activity of T cells in absence of perforin.
