A large number of studies have demonstrated that Trypanosoma cruzi can be controlled by vaccines in animal models, but the identification of effective vaccine antigens represents one of the most critical steps in vaccine development. Thus, only a limited diversity of parasite antigens has been empirically tested as vaccine candidates. More recently, genome-to-vaccine approaches, based principally on T-cell epitope prediction, have emerged as powerful strategies to accelerate vaccine development. In parallel, the increased availability of extensive genomic information on multiple T. cruzi strains offers a major resource for data mining and antigen identification. We present here some of the key strategies for T. cruzi genome mining for antigen discovery and vaccine development.
