Proteomic profiling of extracellular vesicles secreted fromToxoplasma gondii

Toxoplasma gondii infects a wide range of hosts worldwide, including humans and domesticated animals causing toxoplasmosis disease. Recently, exosomes, small extracellular vesicles (EV) that contain nucleic acids, proteins, and lipids derived from their original cells were linked with disease protection. The effect of EVs derived from T. gondii on the immune response and its relevance in a physiological context is unknown. Here we disclose the first proteomic profiling of T. gondii EVs compared to EVs isolated from a human foreskin fibroblast infected cell line cultured in a vesicle-free medium. Our results reveal a broad range of canonical exosomes proteins. Data are available via ProteomeXchange with the identifier PXD004895.
