Changes in blood pDC counts, plasma viral load, and blood CD4+ T-cell counts over time after inoculation with SIVmac251. Absolute counts of pDCs in the blood (A), plasma viral loads (B), proportion of CD4+ T cells with respect to baseline (C). Solid gray lines in panels A, B, and C: macaques infected with 50 AID50; solid black lines in panels A, B, and C: macaques infected with 5000 AID50; dotted gray lines in panels A and C: median plasma viral load of the 50 AID50 group; dotted black lines in panels A and C: median plasma viral load of the 5000 AID50 group.
