Comparison of cytokine production between the Behçet disease (BD)-recurrent uveitis and BD-remitted uveitis groups before and after infliximab infusion. Mean levels of IL-1β (A), IL-4 (B), IL-6 (C), IL-10 (D), IL-17A (E), IL-17F (F), IL-21 (G), IL-22 (H), IL-31 (I), IFN-γ (J), sCD40L (K), and TNFα (L) produced by PBMCs in the BD-recurrent uveitis group before (white bars) and after infliximab infusion (dotted bars) and in the BD-remitted uveitis group before (black bars) and after infliximab infusion (diagonal striped bars). PBMCs were stimulated with IRBP at concentrations of 0, 5, and 10 μg/mL. The line above each bar shows standard deviation. *p<0.05 by Wilcoxon signed-rank test.
