DCs stimulate IFN-γ secretion and proliferation mainly by CD56^bright NK cells. (A) Splenic CD56⁺CD3^– NK cells were analyzed for their CD56^brightCD16^– and CD56^dimCD16⁺ subsets. (B) IFN-γ secretion by purified splenic CD56⁺CD3^– NK cells upon monocyte-derived DC stimulation was analyzed. (C) Proliferation of purified splenic CD56⁺CD3^– NK cells upon monocyte-derived DC stimulation. The numbers in the blots indicate the percentages of the responding NK populations. One of two experiments is shown.
