IL-2–activated NK cells induce DC maturation. (A and B) DC were cultured for 18 h in medium only or in the presence of LPS, IL-2–activated [NK(IL-2)] or untreated [NK(medium)] NK cells. (A) Cells were washed and DC expression of CD86, CD83, CD80, HLA-DR, and CCR7 was analyzed by immunofluorescence. (B) DC, depleted of NK cells and irradiated, were cultured for 5 d with allogeneic naive CD4+ PBL, and 3H-TdR uptake was determined. (C) CD86 expression was determined on DC after an 18-h culture in the absence of any stimulus, or with PBL, or NK-depleted PBL (PBL–NK), either IL-2–activated or untreated.
