Differential susceptibility of human placental trophoblasts to Trypanosoma cruzi infection.

ABSTRACT: Congenital transmission is a key route for Trypanosoma cruzi infection, yet the cellular mechanisms enabling congenital transmission remains poorly understood. This study evaluated the susceptibility of different trophoblast cell line models to T. cruzi infection and compared infectivity patterns among TcI strains compared to Y strain (TcII). The BeWo cell line was used to model cytotrophoblast (CT) and syncytiotrophoblast (ST) cells, while the HTR-8/SVneo cells modeled extravillous trophoblasts (EVTs). Three Colombian TcI strains and one TcII strain were cultured and differentiated into infective trypomastigotes. Infection rates, intracellular parasite replication, trypomastigote release, cell viability, hormone secretion, apoptosis, and ultrastructural characteristics were studied. Signi
