Mediate and regulate immunity through signaling
After recognizing antigens on APCs, what do T helper (TH) cells secrete?
Cytokines for various immune responses
How do T cells recognize antigens on antigen presenting cells (APCs)?

Test your knowledge on Cell-Mediated Immunity (CMI) which is mediated by T cells including Helper T cells (TH) and Cytotoxic T cells (TC). Explore the activation, clonal expansion, differentiation of T cell subsets, and the formation of memory cells in the immune response.
