PfVps32, PfVps60 and PfBro1 proteins are present in EVs produced by pRBCs. STORM detection by immunostaining of GPA, PfVps32, PfVps60 or PfBro1 in purified EVs derived from a 3% parasitemia, 3% hematocrit pRBC culture at 40 hpi. On the right column are shown images of individual EVs. Parasite proteins were observed in EVs purified from a 3% parasitemia pRBC culture at 40 hpi and were absent in EVs from non-infected RBCs , which confirmed our hypothesis and reflected ESCRT-III participation in Plasmodium EV biogenesis. To validate our approach, antibodies against GPA were used to detect EVs from RBC membrane origin.
