Associated to the scholarship:13/00579-9 - Role of inflammasomes and IL-1 in experimental infection by Trypanosoma cruzi, BP.PD


The parasite Trypanosome cruzi is agent causative of Chagas disease. This pathogen causes robust innate immune responses in immunocompetent hosts, resulting in the recruitment of mononuclear cells to the heart. The pattern recognition receptors (PRRs), including TLR-2, -4, -7, and -9, as well as the cytosolic receptor Nod1 recognize pattern molecular pathogen associated to T. cruzi and trigger stronger immune response. Recently, we showed that inflammasomes and IL-1R are necessary for efficient control of this parasite. As both, IL-1a and IL-1b signal via the IL-1R, our goal is to elucidate the immune responses in mice lacking either of these cytokines, as to understand the mechanisms necessary to processing and release of IL-1a and IL-1b.
