(A) CD8+ T cells from EC and CP (freshly thawed or rested) were cocultured with Gag-pulsed autologous CD4s. Degranulation (CD107a) and 5 effector functions (production of IFN-γ, MIP-1β, TNFα, perforin, and granzyme B) were measured by polychromatic flow cytometry. Background levels (measured under no antigen stimulation) were subtracted. Granzyme B and perforin were quantified gating on HIV-specific CD8+ T cells (IFN-γ+). Fold difference: freshly thawed vs. rested. (B) Unstimulated CD8+ T cells from 7 ECs and 7 CPs were stained for CD45RA, CD27, and CCR7 for memory subset profiling. Fold difference: freshly thawed vs. rested CD8+ T cells.
