To test NK cell-mediated killing of cells coated with influenza, bulk primary human NK cell cultures were incubated with anti-NKp46 polyclonal antibodies and assayed against JEG-3 cells in the presence or absence of A/Puerto Rico/8/34 H1N1(PR8) (Figure 1A) or A/Brisbane/59/2007 H1N1 (BRI) (Figure 1B). The gene discussed is NCR1; the disease is influenza.
