Frequency and kinetics of CD56⁻ NK cells. (A) Summary graphs of statistical dot plots with medians (horizontal black bars) showing the percentages of CD56⁻/CD16⁺ (CD56⁻) NK-cell subsets in healthy donors, chronic viremic, LTNP, and early viremic-infected patients. (B) Summary graph of statistical dot plots showing the kinetic of CD56⁻ NK-cell distribution in 33 chronic viremic HIV-1–infected patients having undergone ART (time 0 or baseline; ●) and followed longitudinally every 6 months for 2 years (times 6, 12, 18, and 24; ○).
