LukED targets mature CD56dim NK cells mostly independent of CCR5. (A) Representative flow cytometry plots and combined donor data of the percentage and absolute count of CD56bright and CD56dim NK cells on LukED treatment for 4 h (n = 6). LukED is used at 5 µg/ml throughout the figure. (B) Percentage of depletion of CD56bright and CD56dim NK cells on LukED treatment (n = 6). Representative flow cytometry plots (C) and combined data (D) of the expression of CXCR1, CXCR2, and CCR5 on CD56bright and CD56dim NK cells (n = 6). (E) Representative flow cytometry plots and combined data of the expression of CD27 and NKG2A on CD56bright and the expression of KIRD2L1, CD57, Perforin, and CD16 on CD56dim NK cells with or without LukED treatment (n = 6). (F) Combined data of the percentage of coexpression of the indicated markers on CD56bright (left) and CD56dim (right) NK cells with or without LukED exposure (n = 6). The Wilcoxon signed-rank test was performed to determine significance. The lines and error bars represent mean and SE. *p < 0.05.
