Analysis of the cytolytic activity of NK cells cocultured with macrophages. After coculture with autologous M0, M1, and M2 (with or without LPS), NK cells were analyzed for cytolytic activity against K562 or autologous iDCs either in the presence of cell-to-cell contacts or in transwell (white bars). Average of six independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001.
