BMDCs were generated from Tlr7-/-, c-Junfl/fl or c-JunΔ/Δ Mx1-Cre BM and stimulated with IMQ for 4h and/or pre-treated with SP600125 (JNKi, 25µM) for 1h. Ccl2 mRNA was quantified by qRT-PCR. (n = 4-18; 2-4 experiments). Data information: Data are shown as mean ± SEM. P‐values were calculated by multiple t-test with Tukey multiple comparison test. Statistical significance: ns > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001, **** P < 0.0001. See Appendix Table S3 for exact P‐values.
