CD163 and AIDS: Similarly, ART reduces macrophages in the spleen and significantly (p<0.005) decreases macrophages in the DRG compared to animals with AIDS and SIVE (Spleen SIVE: 1190 ± 348 CD163+/mm2; ART: 1041 ± 40 CD163+/mm2) (DRG SIVE: 10 ± 0.89 CD163+/mm2; ART: 4.5 ± 0.45 CD163+/mm2) (Figure 2E&F).
