WebDec 14, 2024 · While tumor killing is ascribed to CD8 + T cell function, pre-clinical and clinical studies have identified intra-tumoral CD4 + T cells that possess cytotoxic programs and can directly kill cancer cells. Cytotoxic CD4 + T cells are found in other disease settings including infection and autoimmunity. WebCytotoxic T cells destroy virus-infected cells and some cancer cells. Once activated, a cytotoxic T cell divides rapidly and produces an “army” of cells identical to itself. These cells travel throughout the body “searching” for more cells to destroy.
