"Web(A) Direct CTL-mediated killing requires cell–cell contact and commonly results from the release of cytolytic enzymes such as granzyme B. Perforin, released by the CTL, forms pores in the membrane of a juxtaposed target cell allowing passive inward diffusion of granzyme B, which then triggers apoptosis of the targeted cell.

WebPerforin is a monomeric pore-forming protein that is inactive when located within granules, but undergoes a conformational activation, which is Ca2 + dependent. It is related both structurally and functionally to the complement component C9, which forms the membrane attack complex. WebHere is a brief account of how he discovered poly-C9, the pore-forming protein of complement in blood and interstitial fluids: Perforin-1, expressed by natural killer cells and cytotoxic T lymphocytes; and Perforin-2 (MPEG1), expressed by all cell types examined to date. All the three killing systems are crucial for our survival and health.
