Correlation of fractional proliferation rate with viral load.
Proportion of Ki-67–expressing cells among CD4+ (A) and CD8+ (B) T cells in the sum of all organs investigated (see Figure 1) except thymus of uninfected (white bars) and SIV-infected macaques, stratified according to the cell-associated viral load in blood. *Significantly different compared with uninfected monkeys (P ≤ .05). #Significantly different compared with other infected groups (P ≤ .05).
