We observed a reduced NKG2A expression on NK cells of CLL subjects (36.63 ± 3.41 vs. 54.12 ± 3.45 in healthy controls; p < 0.01), while no difference was revealed in the level of NKG2C expression between CLL subjects and healthy individuals (Figure 11C). The gene discussed is KLRC1; the disease is B-cell chronic lymphocytic leukemia.
