Figure 4From: Dynamics of viral replication in blood and lymphoid tissues during SIVmac251 infection of macaquesViral transcription in the two examples of tissue, GALT and spleen, at 14, 21 and 28 days pi. In situ hybridization was performed with radiolabeled SIV-specific RNA and SIV RNA-positive cells appear black. Montage of large image (magnification ×10) of single section, among 4 or 2 sections examined from GALT and spleen, respectively. The encircled regions in the spleen were the most numerous for productive cells. The headed arrow points to a few SIV RNA positive cells founded at day 21 and 28 in the GALT.Back to article page
