Cytotoxic T cells use two basic mechanisms to destroy target cells: 1. Cytotoxic T cells release perforins which create pores on the target cells and granzymes which stimulate the apostosis of the target cells by exocytosis. 2. Cytotoxic T cells bind specific membrane receptors on the target cells and stimulate apostosis process which eliminate the target cells.
