he protozoan Trypanosoma cruzi is the causative agent of Chagas disease, endemic in Latin America but present worldwide. Research efforts have focused on the examination of immune mechanisms that mediate host-protection as well as immunopathology during this parasitic infection. The study of CD8+ T cell immunity emerges as a key aspect given the critical importance of parasite-specific CD8+ T cells for host resistance throughout the infection. In the last years, new research has shed light about novel pathways that modulate the induction, maintenance and regulation of CD8+ T cell responses to T. cruzi. This new knowledge is setting the ground for future vaccines and/or immunotherapies. Herein, we critically review and analyze the latest results published in the field.
