In cell-mediated response, helper T cells bind to presented antigens, divide, and release cytokines that can stimulate phagocytosis, activate cytotoxic T cells, or trigger B cells to produce antibodies.
- foreign or tumour antigens presented by cell - specific helper T cell with complementary receptor binds to antigen - T cell divides rapidly by mitosis - T cell releases cytokines Cloned T cells can: 1 - differentiate into memory cells - immunity 2 - stimulate phagocytosis 3 - activate cytotoxic T cells <div>4 - cytokines stimulate clonal selection - B cells divide by mitosis and differentiate into plasma cells which secrete antibodies</div>
