Cytotoxic T cells (CD8 cells) directly recognize and destroy target cells that bear foreign antigens on their plasma membrane. They do so by releasing cytotoxic granules containing perforin and granzymes, which cause target cell lysis. Neutrophils are important for phagocytosing and killing bacteria, while NK cells are responsible for killing virus-infected and tumor cells. Helper T cells (CD4 cells) help activate and coordinate the immune response, and B cells produce antibodies against foreign antigens.
