Chagas disease is caused by Trypanosoma cruzi, which can be transmitted to the fetus via the transplacental route. Factors that may be involved in transplacental transmission include parasite strain and placental immunological competence. The aim of this work was to compare the biological differences between two subpopulations of T. cruzi with respect to(More)
The aim of the work was to analyze the susceptibility of the placental syncytiotrophoblast (STB) and cytotrophoblast (CTB) cells to infection by the causal agent of congenital Chagas' disease, Trypanosoma cruzi, and the possible parasite route for placental invasion. Monolayers of CTB and STB and VERO as control cells were used. The infection of STB was(More)
Dendritic cells (DC) have the potential to control the outcome of autoimmunity by modulating the immune response. In this study, we tested the ability of Fasciola hepatica total extract (TE) to induce tolerogenic properties in CpG-ODN (CpG) maturated DC, to then evaluate the therapeutic potential of these cells to diminish the inflammatory response in(More)
UNLABELLED We hypothesize that a sustained infection of Trypanosoma cruzi into placental tissue might be diminished. Human placental chorionic villi and VERO cells as controls were co-cultured with T. cruzi. Parasites occupied 0.0137% at 3h, 0.0224% (24h), and 0.0572% (72 h) of the total chorionic villi area analyzed and some few placental samples were(More)
Treatment of Chagas disease is a controversial issue because the available drugs are highly toxic. Clomipramine is a tricyclic antidepressant drug that inhibits Trypanosoma cruzi’s trypanothione reductase, provoking the death of the parasite and preventing the cardiac damage when used for the treatment of acutely infected mice. Here, we studied the(More)
American trypanosomiasis has long been a neglected disease endemic in LatinAmerica, but congenital transmission has now spread Chagas disease to cause a global health problem. As the early stages of the infection of placental tissue and the vertical transmission by Trypanosoma cruzi are still not well understood, it is important to investigate the relevance(More)
Placenta is a transitory organ which simultaneously separate and connect mother and fetus. It has the major importance in the nutrition of fetus, scavenger waste products from fetus, secretion of hormones and immunological factors, allowing fetus to grow in a sea of maternal immunologic environment and regulating mother metabolism. Also, placenta protects(More)
