Figure 2From: Differences in time of virus appearance in the blood and virus-specific immune responses in intravenous and intrarectal primary SIVmac251 infection of rhesus macaques; a pilot studyDepletion of CD4+ T-cells was not observed in tissues of either animal. The CD4+ T-cell population was defined by tricolor staining for CD3, CD4, and CD8. T-cells were defined by gating through CD3+ cells. An equivalent number of cells (1 × 104) was acquired through this gate for each analysis performed.Back to article page
