Perforin and granzyme B expression in CD7⁺CD56⁺CD16⁺and CD7⁺CD56^negCD16⁺NK cells of healthy and chronically infected HIV-1 subjects. A, Granzyme B expression in healthy donors and chronically infected HIV-1 subjects. B, Perforin expression in healthy donors and chronically infected HIV-1 subjects. Healthy subjects n = 10; chronic HIV-1-infected subjects n = 17. The median and 25th and 75th percentile are indicated on each graph. ( = healthy; = HIV-1-infected).
