A selective defect in IL-12 p40 production in c-Rel−/− macrophages. (A) Cytokine expression by peritoneal (Left) or fetal-liver (Right) macrophages was monitored by ELISA. Error bars represent the range of results rather than the standard deviation. (B) The p40 ELISA data from each sample analyzed during this study are shown (○). The ● indicate the average. (C) Gel shift assays were performed with extracts from wild-type (lanes 1–5) and c-Rel−/− (lanes 6–10) peritoneal macrophages activated with LPS/IFN-γ for 4 h.
