CD4+ and CD8+ T-cell subpopulations. A Absolute counts of CD8+ HLA-DR+ T cells/µl. B Absolute counts of CD4+CD45RA+ naïve T cells/µl. C absolute counts of CD8+CD28+ CD27− early effector T cells/µl. D Absolute counts CD8+CD28−CD27− late effector T cells/µl. E Absolute counts CD8+CD57+ terminally differentiated T cells/µl. F Absolute counts CD8+CD28−CD57+ terminally differentiated T cells/µl. Black horizontal lines correspond to the median and errors bars show the interquartile ranges. Red circles: HIV positive and CMV negative individual; Red squares: HIV positive and CMV positive individual; blue circles: HIV negative and CMV negative individual; blue squares: HIV negative and CMV positive individual
