CD4+ T cell counts and SIV-specific antibody responses in tenofovir-treated and untreated macaques infected with SIVmac239Δnef. Tenofovir-treated (1488, 1514) and untreated (1494, 1512) macaques infected with SIVmac239Δnef were challenged intravenously with SIVmac055 and monitored for (A) CD4+ T cell counts, (B) SIV gp130 antibody responses, and (C) SIV p27 antibody responses for approximately one year. Tenofovir treatment was given on days 0–42. Intravenous inoculation of SIVmac055 occurred on day 28 (arrow).
