Tetramer-positive CD8+ T-cells were higher in axillary (A) and mesenteric lymph nodes (C) of the macaque infected intravenously (A, C, D, E, F, and G)12 days postinfection. The CD8+ T-cell population was defined by gating on CD3+ CD8+ lymphocyte population (B). The same number of cells (1 × 10⁴), when possible, was acquired through this gate for every analysis performed.
