T cells are a critical component of host immune responses against bacterial pathogens. T cell activation relies on recognition of antigen(s) derived from the bacteria, and this activation triggers potent biological effector mechanisms. Therefore, the characterization of antigens that are stimulatory for T cells provides insight into host-pathogen interactions and advances rational Vaccine design. The adaptive immune response is defined by its ability to detect variable or unique single-gene products, whereas a 'transitional' immune system recognizes more conserved structures or products of multigene pathways. This transitional system functionally overlaps the canonical innate and adaptive immune responses. Antigen identification has relied upon biochemistry, genetics and expression cloning strategies. The development of computational approaches, fuelled by advances in immunology and genomic information, will facilitate the discovery of antigens and expand our understanding of both beneficial and pathological immune responses.
