Fig. 2 — Changes in peripheral CD4⁺ T-cell populations after intravenous SIVmac239 challenge. (A) % change in mean number of CD4⁺ T cells relative to levels on the day of challenge (P = 0.044 SHIV vs. SIV, one-tailed analyses), (B) mean CD4⁺/CD8⁺ ratios (P = 0.002 SHIV vs. SIV, one-tailed analyses). (•) SIV vaccine-naïve control macaques (n = 4); () SHIV macaques (n = 4) and () Depo-Provera SHIV macaques (n = 3).
