Bioactive IL-12 (p70) is composed of two subunits, p35, which is only secreted as part of the p70 dimer, and p40, which can also be secreted by itself. The IL-12 subunits are encoded by two separate genes. Therefore, we studied to what extent the expression of each of the subunits contributes to the regulation of IL-12 production. We found that in LPS-stimulated whole blood and purified monocytes, p70 and p40 production are enhanced by IFN-gamma and inhibited by IL-10 and IL-4. However, IFN-gamma and IL-10 had stronger effects on p70 production than on p40 production, and IL-4 affected p40 production more strongly. Concomitantly, in all experimental conditions tested, p40 production greatly exceeded p70 production, suggesting that p35 expression was limiting. Analysis of p35 and p40 mRNA expression by PCR confirmed this notion. Resting purified monocytes expressed neither p40 nor p35 mRNA. The effects of IFN-gamma, IL-10, and IL-4 on the p35 mRNA expression in LPS-stimulated purified monocytes were similar to the effects of these cytokines on p70 protein production, and the p40 mRNA expression corresponded to p40 protein production. Our results imply that production of the two IL-12 subunits is differently regulated for each subunit, mainly at the level of mRNA expression, and that the level of bioactive IL-12 production in monocytes in response to LPS and cytokines is determined by the level of p35 expression."xsd:string |
