Again, the expression level of these receptors tended to be higher in the AML mature NK cells than in the control group, ranging from just a marginal difference for the expression of CD158b to statistical significance in the case of CD158e1 (p = 0.008) and CD159a (p = 0.02; Figures 5E–H). The gene discussed is KIR3DL1; the disease is acute myeloid leukemia.
