1. NK activity in healthy donors (n=51) and patients with FRH upon recurrence (n=28) and remission (n=23).
NK activity in healthy donors (n=51) and patients with FRH upon recurrence (n=28) and remission (n=23). MNCs from patients and donors were incubated for 4 h with K562 target cells at the indicated effector/target (E:T) ratios, and the percentages of killed K565 cells were determined as described in Materials and Methods. Squares, diamonds, and triangles denote medians of respective groups; bars represent the 10th and 90th percentiles. *, P < 0.05 (comparison between healthy donors and FRH patients in remission at this E:T ratio).
