Fig 6. Nef9–19, Nef89–97, Nef193–203, and Vif114–124 epitope-specific CD8+ T-cell responses in SIV controllers.

Fig 6

(A) Frequencies of CD8+ T cells specific for SIV Nef9–19, Nef89–97, Nef193–203, and Vif114–124 epitopes in Group M (upper panels) and Group N (lower) at 4 months (4M), 1 year (1Y), and 2 years (2Y) post-infection. (B) Comparisons of the sum of Nef9–19-, Nef89–97-, Nef193–203-, and Vif114–124-specific CD8+ T-cell frequencies at 4M, 1Y, and 2Y between Groups M and N. The sum of CD8+ T-cell frequencies specific for these epitopes in Group M was significantly higher compared to Group N at 2Y post-infection (p = 0.0190 by Mann-Whitney U-test).
