Balance of memory CD8+ T cell populations in HIV-positive individuals with low or high viral set point at 12 mo postinfection. Representation of the proportion of CD8+ T cells memory subpopulations (TCM, TEM, TTM, TInt, and TEff) in total memory and HIV-specific CD8+ T cells at 6–9 mo postinfection in HIV-infected individuals with low (n = 4) or high (n = 4) viral set point. Asterisks indicate significant differences between low and high viral set point individuals (*, p < 0.05; **, p < 0.005).
