IL-12 acts directly on DC to promote nuclear localization of NF-kappaB and primes DC for IL-12 production.

We analyzed the expression of an IL-12 receptor by fresh dendritic cells (DC) and a DC line. Using RT-PCR, RNAse protection, and electrophoretic mobility shift assay analysis, we found that DC possess an IL-12 receptor with beta1 subunit (downstream box 1)-related differences from that on T cells. IL-12 signaling through this receptor involved members of the NF-KB but not STAT family. The unique properties of the IL-12 receptor on DC, characterized by a single class of binding sites with a Kd of about 325 pM, may underlie rather unique effects, such as IFNgamma-independent augmentation of class II antigen expression and priming for LPS-induced production of IL-12.
