Kinetics of surface NKp46 expression after influenza vaccination.

<p>(<b>A</b>) FACS analysis of surface NKp46⁺ NK cell percentages in total NK (black), CD56^bright NK (blue) and CD56^dim NK (red) cells from 8 donor PBMCs at the indicated time points. (<b>B</b>) Longitudinal and phenotypic analysis of NK cells. (CD27⁺, NKp44⁺, CXCR6⁺ and CCR7⁺ NK cell frequencies for subjects #1 and #2 were unavailable.)
