摘要
支气管哮喘是一种严重影响人们生活质量的呼吸系统疾病,多种因素介导该病的发生与发展,其中尤以E-钙粘蛋白(E-cadherin,E-cad)的异常表达最为关键。研究发现,Ecad是一种重要的细胞黏附分子,其主要功能在于维持细胞之间的结构完整性以及参与改善气道的重塑和免疫功能的修复。进一步研究表明,支气管哮喘患者的气道上皮细胞其粘膜屏障功能常常遭受破坏,且黏膜分子E-cad的表达明显降低,这表明E-cad的异常表达参与了支气管哮喘的发生。该文对近年来E-cad的异常表达与支气管哮喘研究进展进行综述,重点对E-cad异常表达介导支气管哮喘发生发展的分子机制进行概述,并对靶向E-cad治疗支气管哮喘的策略进行探讨,为临床的后续研究和治疗提供参考。
Bronchial asthma is a kind of respiratory disease which affects people 's life quality seriously. Many factors in-volved in the occurrence and development of such disease, of which the aberrant expression of E-cad plays a critical role in it. Research found that E-cad is an important cell adhesion molecu-lar, and its main function is to maintain the structural integrity of cells and participate in the improvement of airway remodeling as well as restoration of immune function. Further study showed that the role of mucosal barrier of airway epithelial cells in bronchial asthma patients was often damaged. Moreover, the protein ex-pression of E-cad decreased significantly in mucosal molecular, which suggested that the abnormal expression of E-cad was in-volved in the development of bronchial asthma. A review on the relations between the abnormal expression of E-cad protein and bronchial asthma has been discussed in this paper, also it in-cludes the discussion about the mechanisms of E-cad’ s disorder-induced bronchial asthma as well as explores the strategies of bronchial asthma treatment, which may provide references for the follow-up research and clinical treatment.
