Table 1. Kinetics of the parasites' death under H2O2 treatment.
AnV (+) 7-AAD (−) | AnV (+) 7-AAD (+) | AnV (−) 7-AAD (+) | |
---|---|---|---|
Wild-type (−) H2O2 | 0.033 | 0.007 | 0.004 |
Wild-type (+) H2O2 | 0.14 | 0.42 | 0.79 |
CPC KO (−) H2O2 | 0.29 | 0.07 | 0.02 |
CPC KO (+) H2O2 | 0.29 | 0.28 | 0.18 |
CPC KO/+ (−) H2O2 | 0.16 | 0.04 | 0.02 |
CPC KO/+ (+) H2O2 | 0.32 | 0.45 | 0.53 |
Wild-type parasites (WT), cathepsin B-deficient parasites (cpc KO) and cpc KO complemented strain (cpc KO/+) that contain an episomal copy of cpc were not treated (−) or treated (+) with 1 mM H2O2 for 1 h. Cells were stained with fluorescein isothiocyanate (FITC)-labeled Annexin V and 7-AAD to distinguish between live (AnV−/7AAD−), apoptotic (AnV+/7AAD−, early apoptotic cells; AnV+/7AAD+, late apoptotic/necrotic) and necrotic cells (AnV−/7AAD+) as depicted in Figure 6. Values correspond to ratios of percentage of AnV+/7-AAD−, AnV+/7-AAD+ and AnV−/7-AAD+ cells to percentage of AnV−/7-AAD−
