铁代谢在慢性牙周炎发生发展中的作用研究进展

Research progress on iron metabolism in the occurrence and development of periodontitis

铁代谢是铁元素在生物体内吸收、转运、排泄、储存的过程,包括铁离子和铁结合蛋白在细胞内的生物学活动。临床研究和动物实验表明铁代谢升高与慢性牙周炎进展有关。铁代谢能够增强牙周致病菌的增殖和毒性,激活巨噬细胞、中性粒细胞和淋巴细胞介导的宿主免疫炎症反应。此外,铁代谢还参与调控牙龈成纤维细胞和成骨细胞的死亡敏感性,促进破骨细胞分化,在牙周组织的再生修复中发挥调节作用。本文尝试从铁代谢视角解释慢性牙周炎的发病机制,以期为防治提供新思路。

Iron metabolism refers to the process of absorption,transport,excretion and storage of iron in organisms,including the biological activities of iron ions and ironbinding proteins in cells.Clinical research and animal experiments have shown that iron metabolism is associated with the progress of periodontitis.Iron metabolism not only enhances the proliferation and toxicity of periodontal pathogens,but also activate host immune-inflammatory response mediated by macrophages,neutrophils and lymphocytes.In addition,iron metabolism is also involved in regulating cellular death sensitivity of gingival fibroblasts and osteoblasts and promoting the differentiation of osteoclasts,which plays a regulatory role in the regeneration and repair of periodontal tissue.This article reviews the research progress on the pathogenesis of periodontitis from the perspective of iron metabolism,aiming to provide new ideas for the treatment of periodontitis.
