"When exposed to infected/dysfunctional somatic cells, TC cells release the cytotoxins perforin, granzymes, and granulysin. Through the action of perforin, granzymes enter the cytoplasm of the target cell and their serine protease function triggers the caspase cascade, which is a series of cysteine proteases that eventually lead to apoptosis (programmed cell death). This is called a "lethal hit” and allows to observe a wave-like death of the target cells. Due to high lipid order an… " - Cytolytic effector t cells
