Recovery of CD4⁺ and CD8⁺ naïve to memory T cell ratios in HIV-infected patients with controlled viremia on ART.

<p>Frequencies of naïve (N, CD28^IntCD95^LoCD45RA^HiCCR7^Hi) CD4⁺ T cells (A), and CD8⁺ T cells (B) plotted with increasing CD4 T cell counts in HIV+ and UNC. Frequencies of CD31⁺ and CD31^- cells on naïve CD4⁺ T cells (C), and naïve CD8⁺ T cells (D) in HIV+ and UNC. Frequencies of CD31⁺ and CD31^- cells on naïve CD4⁺ T cells (E), and naïve CD8⁺ T cells (F) plotted with increasing CD4 T cell counts in HIV+ and UNC. (n = 100 HIV⁺, n = 75 UNC) (*p<0.05, **p<0.01, ***p<0.001, ****p<0.0001).
