Figure 5. LPS induced IL-12 expression requires JNK activity.
BMDC from wild-type (WT) or IL-10−/− mice were pre-treated with (A) SB203580, (B) SP600125, (C) U0126, or a corresponding quantity of vehicle control (DMSO) for 1 hour, and then stimulated with Jagged1-Fc or IgG1 in the presence or absence of 100 ng/ml LPS. Concentration of IL-12 in the supernatant after 8 (C) or 24 h (A and B) was measured by ELISA. Data are mean ± SD of triplicates and are representative of at least 3 independent experiments. Two-way ANOVA with Bonferroni post-test was used to statistically compare stimuli; P<0.05 was considered significant. *** = P<0.001, ns = not significant. ND = not detected.
