Resistance of HIC CD4⁺ T cells to HIV-1 is associated with low total cell-associated HIV-1 DNA levels. Total cell-associated HIV-1 DNA levels were compared between HICs whose CD4⁺ T cells yielded ≤ 1 ng of p24/mL of culture supernatant on day 7 after infection with HIV-1 BaL and HICs whose CD4⁺ T cells yielded > 1 ng of p24/mL of culture supernatant. The samples used to calculate cell-associated HIV-1 DNA load and susceptibility to infection were obtained at the same time. Each symbol represents one person. Medians for each group are shown.
