It involves T cells, the T cells exposed to certain antigens undergo division that generate cytotoxic t cells and memory. The cytotoxic T cells find and attack the bacteria, fungi, protozoa or foreign bodies or tissues that contain antigenic material. The cytotoxic Tcells can locate and rapture the antigenic cell membrane and can destroy the invader by secreting a poisonous lymphotoxic substance. Memory T cells remain on reserve ready to respond if the antigen returns at a later date.
