摘要
近年来的研究证实，上皮-间质转化(epithelial-mesenchymal transition, EMT)对呼吸系统发育和疾病有重要作用。细胞间的连接缺失是EMT的关键环节。各类黏附分子的平衡表达对于维持上皮细胞正常结构和功能稳态有重要意义。本文综述了EMT在肺发育、肺损伤修复以及肺部慢性疾病中的研究进展，并结合EMT分子事件的详细过程，就细胞连接结构和细胞黏附分子对EMT的影响作一概述。

Abstract
Epithelial-mesenchymal transition (EMT) plays an important role in the development and pathogenesis of respiratory system. Epithelial cells are characterized by well-developed, intercellular contacts, whereas EMT triggers the sequential destabilization of cell-cell adhesive junctions. The dynamic remodeling of the epithelial cell adhesion molecules is important for maintaining the integrity and normal function of epithelium. This paper reviews the research progress of EMT in lung development, lung injury repair and chronic lung diseases, and summarizes the effect of cell junctions and cell adhesion molecules on EMT molecular events.


Key words: epithelial-mesenchymal transition; lung; airway epithelium; cell junction; adhesion molecules
