The expression of cytotoxicity-related molecules, inhibitory receptors, and killing capacity of NK cells from poly(I:C)-treated mice. Splenocytes or purified NK cells from poly(I:C)-treated mice were stimulated with cytokines and then mixed with CFSE-labeled YAC-1 cells at different E:T ratios as indicated. (a) The killing activity of the splenocytes. (b) The killing activity of the purified NK cells. (c) FCM analyses of perforin, granzyme B, NKp46, NKG2D, NKG2A/C/E, and Ly49A expression gated on splenic DX5+ NK cells. Histograms show representative data from three independent experiments. (d) Histogram shows the statistical analysis of FCM data for the expression of perforin, granzyme B, NKp46, NKG2D, NKG2A/C/E, and Ly49A. Results are presented as . mice per group. Values of were considered statistically significant.
