No correlation between monocyte turnover and blood CD4 T-cell count in SIV- or SHIV-infected rhesus macaques. Peripheral blood samples were obtained from 21 chronically infected rhesus macaques at 24 hours after BrdU inoculation, and the percentage of BrdU-labeled monocytes and blood CD4 count were measured. The Spearman rank test was used to determine the correlation between the percentage of BrdU⁺CD14⁺ monocytes and CD4⁺ T-cell counts.
