Abstract

The autophagy is a homeostatic process cell, where misfolded proteins and damaged organelles are degraded. The autophagy can also be enabled when there is a lack of nutrients or lack of energy (ATP), degrading macromolecules to suppress the lack of these components. In infectious processes, the autophagy helps in the control of microorganisms, which are involved by autophagosomes that fuse to lysosomes, responsible for degradation of the captured microorganism. The molecular Pattern Recognition Receptors (PRRs) of innate immunity are being related to the regulation of autophagy. In this sense, the Toll-Like Receptors (TLRs) activate the process of autophagy, while the role of the cytosolic complexes, the inflammasomes, is still controversial and needs to be better elucidated. Since both the TLRs receptors as the inflammassomes are involved in activation of effector mechanisms for the control of Trypanosoma cruzi, the proposal of this project is to study the role of autophagy as possible effector mechanism for the control of the Trypanosoma cruzi and assess the influence of PRRs in regulation this process.
