Diversity in frequency of KIR2DL1+ and KIR2DS1+ NK cells according to allele typing in 230 healthy blood donors. (A) KIR2DL1 allele/copy number and frequency of KIR2DL1+ NK cells. (B) KIR2DS1 allele and copy number and frequency of KIR2DS1+ NK cells. (C) HLA-C KIR ligands and frequency of KIR2DL1+ NK cells. (D) HLA-C KIR ligands and frequency of KIR2DS1+ NK cells. N represents absence of a KIR2DL1 allele on the KIR haplotype. Unpaired Mann-Whitney test was used. Symbols represent individual samples (mean ± SEM). *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001.
