IgE高亲和力受体与哮喘的研究进展

Progress in the association of high affinity IgE receptor with asthma

儿童哮喘是Ⅰ型变态反应性疾病,IgE在其发病过程中具有极其重要的作用.IgE与其高亲和力受体（FcεR Ⅰ）结合,可以引起肥大细胞的脱颗粒、白三烯的合成和细胞因子的分泌,进而引起气道慢性炎症和气道平滑肌痉挛.目前的研究认为Src激酶家族对FeeR Ⅰ信号传导途径有重要作用.该文综述了关于FcεR Ⅰ的表达调节、信号传导、FcεR Ⅰ与哮喘发病之间的关系及如何应用FcεR εⅠ进行哮喘诊断和治疗.

Childhood asthma is one of type Ⅰ allergic diseases,and IgE is indispensable factor in development of asthma.IgE-antigen crosslinking of hish affinity IgE receptor（FcεRⅠ）leads to degranulation of mast cell,leukotriene synthesis and cytokine production.As a re8ult.such changes will bring about inflammation of airway and spasm of airway smooth muscle.Recent researches suggest that Src tyresine kinase play a vital role in their combination.This review discusses the regulation and signaling trannduction of FcεR Ⅰ and the relationship between FcεRⅠ and asthma.
