Interaction of IL-17 and TGF-β1 for synovial IgA production. Correlation of IL-17 (a) or TGF-β1 (b) levels with anti-LPS IgA response in SF from patients with RA and SpA (Spearman’s rank correlation). c TGF-β1 production in culture supernatants of SF mononuclear cells (SFMCs) (2 × 106 cells/well) following 96 h of stimulation with medium conditioned with different SF containing IL-17 (20 pg/ml). d Total IgA concentrations in SF with IL-17 and TGF-β1 in detectable (+) or undetectable (-) levels. Bars show the mean.*P < 0.05
