Among the HIV(+) children, the total CD4+-cell counts (Figure 1A, p = 0.007), Th1/Th2/Th17-subset counts (Figure 1B–D, p = 0.040/0.012/0.024, respectively), CD4+-cell percentage in lymphocytes (Figure 1F, p = 0.033), and CD8+-cell counts (Figure 1G, p = 0.060) were inversely correlated with age (that is, nearly equal to their HIV-infection period). Here, CD8A is linked to infection.
