On average, in lymphoid tissues treated with IL-7 25 ng/mL there was a decrease in the fraction of APO2.7-positive HIV-1-infected CD4+ (CD8− p24gag+) T cells from 10.9±1.0% to 5.8±0.6% and from 7.7±1.1% to 5.0±0.7% of CD8− p24gag+ T cells on day 6 and 9 post infection, respectively, for HIV-1LAI.04 (n = 8, p<0.001) (Figure 5A). Here, CD8A is linked to infection.
