Chagas disease (CD) is caused by Trypanosoma cruzi and has an acute phase that can progress to the indeterminate and chronic phases. If the infected individual is not treated during the first two phases, 20% to 40% will develop the chronic phase. Treatment is effective only for the acute phase. Specifically, when developing chronic chagasic cardiomyopathy (CCC), which causes the highest morbidity in CD, there is no drug that reverses the damage caused by the parasite at the myocardial level. Recent studies have linked the TGF-β induced signalling pathway to the progression of CD. However, the variation in the expression of protein biomarkers involved along this pathway associated with progression to CCC and serve as predictors of CCC is not yet known. To fill this gap, the TGF-β pathway-associated biomarkers LOXL2, CTGF, Angll, and P38MAPK will be used. Overexpression of these biomarkers amplifies the activation of cardiac myocardial fibroblasts in response to infection and is crucial for the development of CCC. We asked how the relative abundance levels of these biomarkers vary across CD. We hypothesise that the change in expression from the acute phase to the development of CCC of at least one of the molecules will allow it to be used as a potential specific biomarker predictor for CCC. For this purpose, Cavia porcellus, an animal model that develops CD in a similar way to humans, will be used, making it possible to analyse biomarkers at the level of cardiac tissue and serum at different post-infection times. This will be done with the aim that in the future they can be used as biomarkers for predicting the risk of progression to CCC in humans.
