IL-7 increases the proliferation of HIV-1-infected CD4⁺ T cells.

<p>(<b>A</b>) Presented are dot plots for HIV-1-infected CD4⁺ (CD8⁻ p24_gag⁺) T cells isolated from lymphoid tissue blocks infected with HIV-1_LAI.04 or HIV-1_BaL treated or not treated with IL-7 25 ng/mL from a representative donor on day 9 post infection. The amount of Ki-67⁺ HIV-1-infected CD4⁺ T cells is expressed as percentage of total CD8⁻ p24_gag⁺ T cells. (<b>B</b>) Presented are the average fractions of HIV-1-infected CD4⁺ T cells expressing Ki-67 isolated from donor-matched lymphoid tissue blocks infected with HIV-1_LAI.04 or HIV-1_BaL treated or not treated with IL-7 25 ng/mL (means ± s.e.m., <i>n</i> = 6).
