ANXA5 and parasitic infectious disease: Interestingly, in this model, T. gondii infection did not prevent the onset of apoptosis (annexin V+ 7-AAD– cells); however, parasite infection significantly delayed the progression to late apoptosis: on average, 3.3% of cells in the infected culture were 7-AAD+ compared to 11.5% in the mock-infected culture at 24 h postinfection (hpi) (Fig. 3A and B).
