Viral RNA levels in plasma and lymph nodes. (A) Virus levels in plasma of the macaques treated with ART alone (top panel) or ART plus anti–CTLA-4 (bottom panel). (B) SIVmac251 RNA quantified on 1 μg total RNA extracted from macaque lymph nodes before initiation of ART (pre-ART), and after 6 weeks of treatment (ART) and MDX-010 (ART and anti–CTLA-4). Horizontal bars within boxes correspond to the median; box limits correspond to the 25th and 75th percentiles; and vertical lines extend to the 10th and 90th percentiles. (C) Changes in SIVmac251 RNA induced by ART and ART plus MDX-010 (ART and anti–CTLA-4) after 6 weeks of treatment. Mean values plus standard error are shown. (D-E) CD4+ (D) and CD8+ (E) absolute counts per cubic millimeter in blood of the macaques over time.
