Research Project

Our group is mainly focused to investigate the mechanisms involved in the development of effector and regulatory immune response during infections. In these projects, we work in close collaboration with groups led by Drs. Adriana Gruppi and Carolina Montes.

Using the experimental infection with Trypanosoma cruzi as a model, we study basic immune mechanisms involved in protective and pathogenic responses. At present, we are interested in expanding the study of immunological mechanisms discovered in our laboratory to other models of chronic diseases such as cancer and autoimmunity. While our laboratory has a strong imprinting in basic research, one of our ongoing goals is to translate our findings from animal models into clinical research.

Specifically, the projects currently underway are:

  • Study of the role of cytokines that signal via IL-17RA in the development of immunity CD8 + T cells against Trypanosoma cruzi
  • Study of the contribution of regulatory T cell response in the progression of the infection with Trypanosoma cruzi
  • Study of the role of cytokines IL-17 family in the induction of antitumor cytotoxic response and tumor progression
