NLRX1 but not NLRC5 controls the RIG-I/MDA5 agonist-induced type I IFN and pro-inflammatory responses in human moDCs. (A–D) moDCs transfected with the indicated siRNAs were stimulated with the RIG-I/MDA5 ligand polyI:C (1 μg/ml). The protein levels of IFN-α, IFN-β (A), TNF, IL-6, and IL-8 (B) were detected by ELISA after 24 h. (C,D) Kinetics of IκBα degradation was determined by western blotting. (C) A representative blot is shown. (D) Bar graphs show the relative density of IκBα measured at 60 min of stimulation. (A,B,D) Data are shown as mean ± SD from 4 independent experiments and analyzed using one-way ANOVA followed by Bonferroni's post-hoc test. **p < 0.01, ***p < 0.01 ****p < 0.0001 vs. untreated; #p < 0.05, ##p < 0.01, ####p < 0.0001, n.d., not determined.
