Figure 1From: CD4+ T cells apoptosis in Plasmodium vivax infection is mediated by activation of both intrinsic and extrinsic pathways Flow cytometric analysis of apoptosis. Representative example of gating strategy used to characterize CD4+ T cells in apoptosis, using co-staining with Annexin-V and PI (A). Percentage of CD4+ T cells in early (B) and late (C) apoptosis from malaria-naive donors (n = 11) and P. vivax-infected donors (n = 20). An unpaired t-test was used for comparison and the results were expressed as the mean ± SEM.Back to article page
