WebStudy with Quizlet and memorize flashcards containing terms like Saliva and lacrimal fluid contain __________, an enzyme that destroys bacteria., Important in recruiting other … 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…

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.
