Figure 2. CMV reactivation induces a mature phenotype of NK cells (CD56^dim) expressing NKG2C and KIR after haplo-HSCT.

The percentages of CD56^dim NK cells A., as well as NK cells expressing NKG2C B., NKG2A C. and KIR D. in the CD56^dim subset were determined by flow cytometry in patients with (■, n = 19) without CMV reactivation (□, n = 10) at days 30, 60, 90, 120, 150, and 180 after haplo-HSCT. Values represent mean ± SEM. *P < 0 .05 and ns (not significant) P > 0.05 for comparisons between the CMV reactivation and no reactivation groups.
