Abstract

Autophagy is a homeostatic process by which misfolded proteins and damaged organelles are degraded. Autophagy also contibutes to degrade macromolecules under starvation. In infectious processes, autophagy helps to control microorganisms by deliverying them to degradation in autolysosomes. Pattern recognition receptors (PRRs) have been related to the regulation of autophagy. Toll-like receptors (TLRs) activate the process of autophagy, whereas the role inflammasomes is controversial and remains to be elucidated. Since both TLRs and inflammassomes are involved in the control of Trypanosoma cruzi (T. cruzi), the present proposal aims to elucidate the role of autophagy in host resistance against T. cruzi and to uncover molecular mechanisms mediated by PRRs to regulate this process.
