Human MoDCs (104 DCs per 200 μl in experiments 1 and 2, 105 DCs per 200 μl in experiment 3) were incubated with CD40L (experiments 1 and 2) or a mix of stimuli containing LPS, poly I:C, CpG, and an mAb for CD40 (experiment 3), and cytokines as indicated for 2 d (experiments 1 and 2) or 1 d (experiment 3). The amount of IL-12 p70 and p40 produced was analyzed by ELISA.
