Our laboratory is mainly interested in the study of the immune response developed in the infected subjects during the chronic phase of Chagas disease.

Our aim is to elucidate the mechanisms of pathogenesis that lead chronic asymptomatic patients to suffer cardiac disorders, as well as to identify new targets with projection to the development of vaccines and/or drugs.
