rsIL-7gly was administered where indicated [↓]. The nuclear antigen Ki67 was used to assess proliferating cells, pre-rsIL-7gly levels of proliferation were determined by averaging the percentage of Ki67+ cells in each subset over three timepoints. The difference in Ki67 expression from pre-rsIL-7gly levels was determined for each subsequent timepoint and is presented as the mean±standard error of the mean (SEM). The dashed horizontal line indicates pre-rsIL-7gly Ki67 levels. (A) Change in percent Ki67+ cells in CD4+ subsets including naïve, central memory (CM), transitional memory (TrM), and effector memory (EM); (B) change in percent Ki67+ cells in CD8+ subsets. Uninfected macaques (N=8; grey), SIV+ART treated macaques (N=6; black)
