مستخلص: The life cycle of Trypanosoma cruzi, the etiological agent of Chagas disease, involves different forms of the parasite, which alternates between insect and vertebrate hosts. One critical process in the parasite's life cycle is metacyclogenesis, in which the replicative non-infective forms present in the insect midgut differentiate into non-dividing vertebrate-infective forms. It is known that proline (Pro) is important for this process and that leucine (Leu) and isoleucine (Ile) can act as inhibitors of metacyclogenesis. In this study, we investigated further the role of branched-chain amino acids (BCAAs) as negative modulators of parasite differentiation and infection capability in vitro. We found that BCAAs can down-regulate metacyclogenesis, inhibiting Pro-dependent differentiation. Furthermore, we evaluated the ability of all three BCAAs to influence the differentiation of intracellular stages and found that they could modulate the release of trypomastigotes from infected host cells. These findings suggest that BCAAs may have an important role in the complex life cycle of T. cruzi. Thus, enzymes of their metabolism and other interacting proteins could be potential targets for the development of new therapeutic strategies for Chagas disease.
