(A) Antibody titers against the SHIVSF162P3 gp140 trimer were measured before week 10 p.i. and after week 17 p.i. in the bNAbs-only and bNAbs–Rh-α4β7 treatment groups. Results are compared by two-way ANOVA with Sidak’s multiple comparisons test. (B) Shown is the frequency of CD4+ T cells (left) and CD8+ T cells (right) secreting IFN-γ, TNF-α, or both, after PBMC stimulation for 6 hours with CD28/CD49d and a HIV consensus B envelope peptide pool, a gag pool, or a pool of 15-mer overlapping peptides from the V2 loop of the SHIVSF162P3 Env. Data from the two treatment groups are compared by Kruskal-Wallis test and the results of the Dunn’s multiple comparisons post hoc test. *P < 0.05. Bars represent means ± SD.
