Trypanosoma cruzi PAN 4 exosomes LC-MS/MS

Here we report the proteome content of exosomes released by epimastigote and bloodstream trypomastigotes forms of T. cruzi, the aetiological agent of Chagas disease. The exosomes were isolated using the ultracentrifugation method and further processed for LC-MS/MS. The results showed differential proteomic profiles of this two forms with marked differences in surface molecules cargoes. Noteworthy, the trans-sialidase (TS) surface proteins, a family of polymorphic virulence factors were differentially expressed between insect and human stages of T. cruzi highlighting the different surface nature of this two parasite stages.
