Frequency and kinetics of Siglec-7⁺ NK cells. (A) Summary graphs of statistical dot plots with medians (horizontal black bars) showing the percentages of Siglec-7⁺ NK-cell subsets in healthy donors, chronic viremic, LTNP, and early viremic-infected patients. (B) Summary graph of statistical dot plots showing the kinetics of Siglec-7⁺ 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; ○).
