Abstract

Cell invasion by Trypanosoma cruzi extracellular amastigotes involves different signaling pathways to induce phagocytosis-like mechanisms. Previous works indicated that PI3K/Akt, Src and Erk might be involved in EA invasion; however, participation of these molecules in this process remains elusive. Here, we observed that EA activated Akt, Erk but not Src. Interference of EA invasion with specific inhibitors corroborated this observation. Our results show that EA is capable of selectively triggering complex signaling pathways. Activation of PI3K/Akt and Erk, kinases related to actin cytoskeleton rearrangement and phagocytosis, reinforces the idea that T. cruzi EA subverts the phagocytic machinery during invasion.
