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.
