多种细胞、细胞因子以及炎症介质通过多条信号途径参与了哮喘患者气道高反应性、慢性炎症以及重塑发生的过程,其中TGF-β/Smad信号通路是目前研究的热门之一。本文主要介绍TGF-β超家族,Smad蛋白家族,TGF-β/Smad信号通路,抑制性蛋白对TGF-β/Smad信号通路的调控以及其在哮喘气道重塑中的作用。
Many kinds of cells, cytokines, mediators of inflammation participate in the process of airway hyperreactivity, chronic inflammation, remodeling of asthma through many signal pathways, TGF-β/ Smad signal pathway is one of the most hot signal pathways in studying at present. This article mainly introduces TGF-β superfamily,Smad proteinnum family, TGF-β/Smad signal pathway, the role of I-Smad in TGF-β/Smad signal pathway and airway remodeling of asthma.
