Abstract

Several studies have described the relevance of the amino acids in the biology of several protozoa parasites such as Trypanosoma cruzi, the etiological agent of Chagas disease. Besides their role in protein synthesis and energy metabolism, amino acids are also involved in different biological processes in the parasite. Among them, it is worth mentioning the differentiation between stages, the energetic support to the host-cell invasion, the establishment of the infection and the resistance to different stresses the parasite faces during its life cycle, such as osmotic, thermal, oxidative and nutritional. Until now, different roles of several amino acids were evaluated individually, but an integrated and systematic view of the role of main amino acid metabolic pathways and their interactions is still lacking. Taking into account this gap, this project aims: (1) To develop a metabolic chart for the amino acids with focus on that having a role in the bioenergetic of T. cruzi, including the identification of auxothrophies for these metabolites. (2) To evaluate their intervention on: i) the induction of ATP synthesis, production of H2O2, respiratory burst and mitochondrial membrane potential, ii) differentiation, iii) support of the host-cells invasion, iv) resistance to osmotic, oxidative, thermal, nutritional, acidic stress as well as toxicity due to NH4+ accumulation, v) the modulation of cell cycle, autophagy and the programmed cell-death triggered by metabolic stress. (3) To evaluate the roles of enzymes participating of the metabolism of those amino acids having activities described in (2), as well as the effect of their chemical inhibition or overexpression, on different aspects of the biology of the parasite mentioned in (2). (4) To perform a comparative study of the different metabolic pathways activity among different stages by targeted metabolomics. (5) To develop knock-out lineages by CRISPR/Cas9 for the most relevant enzymes among those of the amino acids metabolism for different aspects of the biology of the parasite mentioned in (2) to evaluate their possible effects related to their therapeutic potential. To evaluate by metabolomics the effect of the gene suppression or the treatment of inhibitors on the metabolic profile of the cells. (6) To evaluate the impact of the amino acids metabolism on the management of the excess of NH4+ and the production of amino sugars and glycoconjugates. (AU)
