Expression of the NKG2D and 2B4 coactivation receptors on NK cell subsets from Nandi, Kisumu, and eBL children. NK cell subsets, including CD56^brightCD16^neg (1), CD56^brightCD16^pos (2), CD56^dimCD16^pos (3), and CD56^negCD16^pos (4), were evaluated for each group of children: Nandi (EBV^low/malaria^low), Kisumu (EBV^high/malaria^high), 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.
