i.v. and IVAG infection of macaques. (A) i.v. infection of rhesus macaques with SHIV_SF162PC. (B) IVAG infection of rhesus macaques with SHIV_SF162PC. Filled symbols indicate viral loads expressed as RNA copies per milliliter, while empty symbols depict CD4/CD8 cell ratios. (C) Percentages of CD4⁺ lymphocytes from PBMCs, colonic lymph node mononuclear cells (LNMC), and lamina propria (LPL) during acute infection. The percentage of CD4⁺ lymphocytes in the intestinal tract of uninfected macaques has been shown to be in the range of 34 to 57% (75).
