Abstract：Objective To investigate the mechanism of IL-17, the signature cytokine produced by Th17 cells, in OLP lesion. Methods 24 patients with reticular OLP, 19 patients with atrophic-erosive OLP and 13 healthy volunteers were enrolled in this study . Real-time quantitative PCR ( real-time qPCR ) was performed to analyze the expressions of the production of IL-17 and CCL20 mRNA. Results The expressions of IL-17 mRNA in reticular OLP and atrophic-erosive OLP were significant higher than that in healthy oral mucosa (P = 0.0095, P <0.0001, respectively), meanwhile, remarkable increased IL-17 expression in atrophic-erosive OLP group was found compared with reticular OLP group (P = 0.0012). Additionally, the expressions of CCL20 mRNA in reticular OLP and atrophic-erosive OLP were significant higher than that in control group (P=0.0357, P<0.0001, respectively), meanwhile, CCL20 expression in atrophic-erosive OLP was higher than that in reticular OLP. The expressions of CCL20 mRNA rises with the increased expression of IL-17, and were positive correlated with IL-17 expressions in OLP lesions (P=0.003). Conclusions IL-17 production can induce chemokine CCL20 expression in OLP lesion. The signal pathway may promote the migration and infiltration of inflammatory cells in OLP lesions.
