Figure 2.
Sequential PRR stimulation of BMDC enhances cytokine mRNA expression and NFκB and MAP kinase signaling. (A) Il-6, Il-12a, and Il-12b mRNA expression 4 and 8 h after the second stimulation in BMDC stimulated as in Fig. 1. Mean + SEM of four to eight independent experiments are shown. (B) Immunoblot analysis of p65 and MAPK in BMDC stimulated with combinations of poly(I:C) and R848, at 0, 20 and 40 min, after the second stimulation. Individual blots are indicated by rectangles and are representative of three independent experiments. *p < 0.05; **p < 0.01; ***p < 0.001, and ****p < 0.0001, compared to the sequential PRR stimulation; one-way ANOVA, Dunetts post-test.
