Fig. 3From: Immunosenescence of the CD8+ T cell compartment is associated with HIV-infection, but only weakly reflects age-related processes of adipose tissue, metabolism, and muscle in antiretroviral therapy-treated HIV-infected patients and controlsCD8+ T cell exhaustion and senescence in HIV+ and in Controls. a Proportions of PD-1+ cells in total CD8+ T cells and in CD8+ T cell subsets in HIV-infection and in Controls. HIV+ (N = 43) and Controls (N = 10). b Proportions of KLRG1+ cells in total CD8+ T cells and in CD8+ T cell subsets in HIV+ and in Controls. HIV+ (N = 30) and Controls (N = 9). Medians are shown as horizontal bars. P-values were determined using unpaired Student’s t-test or Wilcoxon two-sample testBack to article page
