Abstract: The role of vaccines to tuberculosis and leprosy is to induce a cellular immunity, and as a result to induce the differentiation of memory CD8+ cytotoxic T cells. 'Help' from CD4+ T cells is important for the differentiation of naive CD8+ T cells to effector and memory CD8+ cytotoxic T cells. However, how CD4+ T cell 'help' is involved in the steps instructing T helper (Th) polarization is not yet clear. Peptide-25, a major Th epitope of Ag85B from Mycobacterium tuberculosis, preferentially induced development…
