Figure 2. Flow cytometry analyses showing the distribution of total CD3⁺ T cells along with subsets CD4⁺ CD8⁻ (CD4⁺ T cells) and CD4⁻ CD8⁺ (CD8⁺ T cells).

Panel A: data from a representative animal from each of the three groups of macaques with different viral loads: Long-term non-progressors (LTNP), chronic viremia (Chronic), and highly viremic (Viremic). Panel B: comparison of the average values for the numbers of total CD3⁺ T cells as well as CD4⁺ CD8⁻ and CD4⁻ CD8⁺ T cells subsets in all the animals studied in the LTNP, Chronic and Viremic groups of monkeys. The data are shown as the mean ± SEM. The Horizontal bars represent the group mean, error bars represent SEM. Statistical differences between groups are indicated by the p values.
