Expression of T cell activation markers on CD4⁺and CD8⁺T cells in patients and healthy controls. Whisker plots were used to compare the antibody-binding capacity (ABC) of CD95⁺ CD4⁺ T cells (panel A and B) and CD38⁺ CD8⁺ T cells (panel C) between HIV-1 infected subjects and healthy controls from the different study sites using the Mann-Whitney U-test. Panel A shows data on the ABC of CD95^dim CD4⁺ CD3⁺ cells, panel B on the ABC of CD95^brightCD4⁺ CD3⁺ cells, and panel C shows the comparison of the ABC of CD38 CD8⁺ CD3⁺ cells between HIV-1 infected subjects and healthy controls from Nouna (rural) and Ouagadougou (urban). Symbols: (*) indicates statistically significant difference (p < 0.05) between healthy controls in Ouagadougou (urban) and healthy controls in Nouna (rural).
