Facilitated diffusion through the perforin pore


Cytotoxic lymphocytes eliminate virally infected or neoplastic cells through the action of cytotoxic proteases (granzymes). The poreforming protein perforin is essential for delivery of granzymes into the cytoplasm of target cells, however the mechanism of this delivery is incompletely understood. Perforin contains a membrane attack complex / perforin… (More)
