Expression of the NKG2D and 2B4 coactivation receptors on NK cell subsets from Nandi, Kisumu, and eBL children. NK cell subsets, including CD56brightCD16neg (1), CD56brightCD16pos (2), CD56dimCD16pos (3), and CD56negCD16pos (4), were evaluated for each group of children: Nandi (EBVlow/malarialow), Kisumu (EBVhigh/malariahigh), and BL with low EBV and BL with high EBV. NKG2D expression by (A) NK cell subset representation (A) and by linear representation (B) across study groups (Nandi, n = 8; Kisumu, n = 6; and BL, n = 11). 2B4 expression by NK cells subset representation (C) and by linear representation (D) across study groups (Nandi, n = 6; Kisumu, n = 4; and BL, n = 10). Data are mean ± SD. *P < .05, **P < .01, ***P < .001.
