WebPerforin 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. WebApr 9, 2024 · Figure 13.2 B. 1: (left) Cytolysis of Gram-Negative Bacteria, Step 1. The Fab portion of IgG or IgM binds to epitopes on the outer membrane of the gram-negative cell wall. This activates the complement pathway enabling the membrane attack complex (MAC) to insert through the outer membrane and cytoplasmic membrane causing the bacterium …
