T helper 17 (Th17) cells are a new type of CD4+ T helper cell. They participate in the immune and inflammatory response by secreting specific interleukin-17 (IL-17). In oral mucosal diseases, oral lichen planus (OLP), recurrent aphthous ulcer (RAU) and Behcet′s disease (BD) are associated with Th17 cells and IL-17. There were 17 kinds of proteins in the saliva of patients with OLP that could upregulate the expression of Th17 cells and induce the secretion of IL-17. IL-17 can stimulate epithelial cells, endothelial cells and fibroblasts to produce a variety of cytokines, such as IL-6, IL-8, granulocyte macrophage colony-stimulating factor and cell adhesion molecule-1, leading to the production and aggravation of inflammation. Th17/Tc17 cell-targeted therapy can significantly improve the clinical symptoms of OLP patients′ mucosa and skin. IL-17 can stimulate oral keratinocytes through the IL-17RA or IL-17RE receptor and produce proinflammatory effects in RAU. Th17 cells in the peripheral blood of BD patients are significantly increased, while Treg cells are significantly decreased.

辅助性T细胞17(T helper cells 17,Th17)细胞是一种新的CD4+T辅助细胞,其通过分泌特有的白细胞介素17(interleukin 17,IL-17)参与机体免疫及炎性反应。在口腔黏膜疾病中,口腔扁平苔藓(oral lichen planus,OLP)、复发性阿弗他溃疡(recurrent aphthous ulcer,RAU)、白塞病(Behcet′s disease,BD)的发病均与Th17细胞、IL-17相关。OLP患者唾液中有17种与OLP发生相关的、可上调Th17细胞的表达及诱导IL-17分泌的蛋白质;IL-17通过刺激上皮细胞、内皮细胞、成纤维细胞产生多种细胞因子,如IL-6、IL-8、粒细胞-巨噬细胞集落刺激因子及细胞黏附分子1,致使炎症的产生及加重;Th17/Tc17细胞的靶向治疗可使OLP患者黏膜和皮肤的临床症状得到明显改善。IL-17可通过IL-17RA或IL-17RE受体刺激口腔角质细胞,在RAU中产生促炎作用。BD患者外周血中Th17细胞明显增高,而Treg细胞显著降低。
