Non‐specific antibody‐dependent natural killer (NK) cell responses were correlated with the loss of CD16 on NK cells. the potency of the antibody‐dependent NK cell responses were calculated as the frequencies of CD107a⁺ (a) or interferon (IFN)‐γ⁺ (b) NK cells incubating with antibody‐bound P815 cells minus the percentage of these cells incubating with P815 cells alone. The Pearson's correlation test was used to evaluate correlations between groups. Loss of CD16⁺ cells on CD56⁺ NK cells indicated CD16 mean fluorescence intensity (MFI) of these cells stimulated with P815 cells alone minus CD16 MFI following stimulation with antibody‐bound P815 cells. All P‐values are two‐tailed and were considered significant when less than 0·05.
