FIG. 3.

Blocking NKG2A or NKG2D receptors does not affect binding of N. americanus ES products to NK cells. PBMCS from egg-negative donors from areas of nonendemicity in the United States (n = 3) were incubated with/without anti-NKG2A or -NKG2D, followed by incubation with bioES and then costaining with FITC-streptavidin and PE anti-CD56/CD16. Dot plots show representative distributions of ES binding relative to CD56/CD16 staining for cells with no blocking, anti-NKG2A blocking, and anti-NKG2D blocking. The percentage of NK cells (CD56⁺ CD16⁺) staining positive for bioES is shown for each group.
