We performed FACS analysis of CD4(+) CD31(+) naïve T cells from PBMCs in a cross-sectional age-matched cohort, including 25 healthy controls (HC), 18 untreated HIV-1 infected viremic progressors (VP), 10 untreated HIV-1 infected viral controllers (VC), and 24 HIV-1 infected immune responders (IR) following ART.
