Descrição: Extracellular vesicles released from pathogens may alter host cell functions. We previously demonstrated the involvement of host cell‐derived microvesicles (MVs) during early interaction between Trypanosoma cruzi metacyclic trypomastigote (META) stage and THP‐1 cells. Here, we aim to understand the contribution of different parasite stages and their extracellular vesicles in the interaction with host cells. First, we observed that infective host cell‐derived trypomastigote (tissue culture‐derived trypomastigote [TCT]), META, and noninfective epimastigote (EPI) stages were able to induce different levels of MV release from THP‐1 cells; however, only META and TCT could increase host cell invasion. Fluorescence resonance energy transfer microscopy revealed that THP‐1‐derived MVs can fuse with parasite‐derived MVs. Furthermore, MVs derived from the TCT–THP‐1 interaction showed a higher fusogenic capacity than those from META– or EPI–THP‐1 interaction. However, a higher presence of proteins from META (25%) than TCT (12%) or EPI (5%) was observed in MVs from parasite–THP‐1 interaction, as determined by proteomics. Finally, sera from patients with chronic Chagas disease at the indeterminate or cardiac phase differentially recognized antigens in THP‐1‐derived MVs resulting only from interaction with infective stages. The understanding of intracellular trafficking and the effect of MVs modulating the immune system may provide important clues about Chagas disease pathophysiology.
