Figure 4. Improved killing of K562 cells by NK cells in the presence of DC when K562 cells are sensitized with poly(I:C).

Figure 4

Percentage killing of mock- and poly(I:C)-electroporated K562 cells by NK cells or by NK cells and DC. Cocultures were kept overnight at a 1∶1 NK:K562 or a 1∶1∶1 NK:DC:K562 cell ratio. Horizontal lines represent mean of 7 donors. Differences are statistically significant if p<0.05. Abbreviations: mock EP, electroporated without poly(I:C); pIC EP, electroporated with poly(I:C).
