Extended Data Fig. 1. CD123NKCE promotes strong killing activity against AML cells that is not affected by the expression of CD64.

Extended Data Fig. 1

a, Phenotype of the 14 AML cell lines used in the study showing the expression of CD64 and CD123 at the cell surface by flow cytometry. Antibody binding capacity (ABC) values for CD123 are indicated. b, Maximum cytotoxic activities of the anti-CD123 antibody (CD123-IgG1+; black), NKp46-Fc null-CD123 NKCE (red), and IgG1 isotype control (IC-IgG1+; white) against AML cell lines. AML cell lines were used as targets and purified NK cells from 4 healthy donors were used as effectors. Data are presented as mean values ± s.d. c, Delta (Δ) maximum lysis, defined as percent maximum lysis of the compound minus percent background lysis of the isotype control molecule (IC-IgG1+) at the corresponding concentration, were monitored from the dose response of each compound, and were plotted separately for all couples of CD64positive and CD64-negative AML cell lines/NK donor. (ns P > 0.05; **** P ≤ 0.0001; two-sided Wilcoxon matched-pairs signed rank test).
