Distribution of NK cell subsets. A, Frequency of classically defined NK cell subsets within the CD3^neg CD14^neg CD19^neg population of healthy donors ((•) N, n = 63) and early- ((☐) E, n = 9) and chronically- (() C, n = 19) HIV-1-infected subjects. B, Frequency of CD3^neg CD14^neg CD19^neg cells expressing CD7 within the CD56^brightCD16^neg, CD56⁺CD16⁺ and CD56^negCD16⁺ subsets in healthy ((•) N, n = 63) and early- ((☐) E, n = 9) and chronically- (() C, n = 19) HIV-1-infected subjects. C, Frequency of CD56^negCD16⁺ cells within the CD3^neg CD14^neg CD19^neg population (left axis) and of CD3^neg CD14^neg CD19^neg cells expressing CD7 within the CD56^negCD16⁺ subset (right axis) of CMV-negative (closed circles) and CMV-positive (open circles) healthy donors. The median and 25th and 75th percentile are indicated on each graph.
