摘要: 牙周炎是由菌斑微生物引起的一种感染性疾病,其中宿主的免疫系统在应对细菌入侵的同时,也会引起牙周组织的炎症反应,从而产生相关的病理表现。在炎症反应中,组织蛋白酶发挥重要的作用。其中,组织蛋白酶B可促进巨噬细胞表达白细胞介素-1β(IL-1β)与肿瘤坏死因子-α(TNF-α);组织蛋白酶S参与T细胞向辅助性T细胞17(Th17)方向分化,并与组织蛋白酶B共同引起血管反应;组织蛋白酶C和G可促进中性粒细胞IL-1β的活化;组织蛋白酶K参与破骨细胞介导的骨吸收。文章将总结组织蛋白酶在牙周炎的炎症反应及临床病理中发挥的作用,从而对牙周炎发病机制的研究及临床诊疗起到一定的提示与指导作用。

Abstract: Periodontitis is an infectious disease caused by plaque microorganisms,in which the host immune system not only responds to bacterial invasion but also causes inflammatory response in the periodontal tissues,resulting in the associated pathological manifestations. Cathepsins play important roles in inflammatory response. Among them,cathepsin B promotes the expression of interleukin-1β(IL-1β)and tumor necrosis factor-α(TNF-α) of macrophages;cathepsin S is involved in the differentiation of T cells towards T helper cell 17(Th17)and causes vascular responses together with cathepsin B;cathepsin C and G promote the activation of IL-1β of neutrophils,and cathepsin K is involved in osteoclast-mediated bone resorption. In this paper,we will summarize the role of cathepsins in the inflammatory response and clinicopathology of periodontitis,thus providing suggestions and guidance for the study of the pathogenesis and clinical diagnosis and treatment of periodontitis.
