支气管哮喘(简称哮喘)是一种气道的慢性炎症性疾病,许多类型的细胞起到了重要作用,特别是肥大细胞、嗜酸粒细胞和T淋巴细胞.气道高反应性、炎症和重塑是哮喘的主要特征.气道重塑的特点包括上皮下纤维化,成纤维细胞增生,肌细胞增生和肥大,连同上皮细胞损伤杯状细胞化生、水肿和血管增加.气道高反应性与气道重塑和气道炎症密切相关.整合素作为一类黏附分子的受体是多功能蛋白质,把细胞连接到细胞外基质和组织细胞边缘的整合素黏附复合物.它还控制着细胞的命运和功能,通过影响细胞的增殖、凋亡和分化.各种各样的整合素异二聚体是从9种β亚基和24种a亚基组合形成的.他们是异二聚体,作用是细胞外基质和肌动蛋白骨架的横跨膜的连接器.整合素还作为信号转换器,当矩阵绑定激活时激活各种细胞内信号转导通路.整合素和常规的信号受体经常合作,促进细胞生长,细胞存活,细胞增殖.而近年来对不同整合素与哮喘相关性的研究越来越多,以下就对不同整合素进行阐述.

Bronchial asthma (asthma) is a chronic inflammatory disease of the airways in which many cell types play a role,in particular mast cells,eosinophils and Tlymphocytes.Airway hyperresponsiveness,inflammation and remodeling are the key feature of asthma.The characteristics of airway remodelling include subepithelial fibrosis,myofibroblast hyperplasia,myocyte hyperplasia and hypertrophy,together with epithelial damage,goblet cell metaplasia,oedema and increased vascularity.Airway hyperresponsiveness is associated with features of both remodelling and airway inflammation.Integrins,which constitute one class of cell-adhesion receptor,are multifunctional proteins that link cells to the extracellular matrix and organise integrin adhesion complexes at the cell periphery.Integrins also control the fate and function of cells by influencing their proliferation,apoptosis and differentiation.A variety of human integrin heterodimers are formed from 9 types of β subunits and 24 types of α subunits.They are heterodimers and function as transmembrane linkers between the extracellular matrix and the actin cytoskeleton nction as signal transducers,activating various intracellular signaling pathways when activated by matrix binding.Integrins and conventional signaling receptors often cooperate to promote cell growth,cell survival,and cell proliferation.In recent years different integrin associated with asthma research more and more,the paper elaborated following different integrin.
