Abstract Trypanosoma cruzi, a parasitic hemo-flagellate, is the causative agent of Chagas disease. This disease constitutes a major health hazard to humans in South and Central America. Thus far, no successful chemotherapeutic cure or immunological prevention has been developed. Since both humans and animals can develop acquired resistance to acute infections of Trypanosoma cruzi, an effective immunophrophylaxis for controlling this parasite should be practical with adequate knowledge. This will include an understanding of the anti-parasite immune responses and a clear distinction between those parasite antigens which do and do not provide immunity. Accordingly, a major emphasis of our research is to identify relevant antigens and to develop methods for acquiring these antigens in sufficient amounts to test their vaccination properties. Our laboratory has identified three parasite antigens which provide protective immunity to mice against an otherwise lethal challenge by Trypanosoma cruzi. The genes which encode these antigens have been cloned, and these proteins have been expressed in both eucaryotic and procaryotic systems in amounts sufficient for immunological testing. We are currently mapping the relevant T and B cell epitopes that elicit the protective responses, and studies to determine the immunological basis for protection are in progress. Future studies will include the development of new multiple antigen presenting systems using the selected T and B cell epitopes. Studies to define CD8+ cytolytic epitopes in specific Trypanosoma cruzi antigens are also in progress. |
