摘要
自然杀伤(natural killer,NK)T细胞是一种同时具有自然杀伤细胞和T细胞部分表型及功能的细胞亚群,能将先天性免疫应答和获得性免疫应答连接起来,限制性识别CD1d-糖脂抗原,并通过调节细胞因子的分泌,影响辅助性T细胞1型(T help cell type1,Th1)/Th2平衡,广泛参与免疫调节。近年研究发现,自然杀伤T细胞对哮喘Th1/Th2失衡及气管高反应(airway hyper responsiveness,AHR)产生起重要作用。本研究就自然杀伤T细胞的特征及其与支气管哮喘关系的最新研究进展,综述如下。
Natural killer I(NIX 1 )cells are a umque subset oI tympnocytes,wmcn express botn T and natural killer (NK) cell surface markers as well as functional characteristics. They connect innate and acquired immunity,restrictedly recognize glycolipid antigens presented by CD1d molecule and influence the balance between T helper cell type 1 (Thl)and Th2 by regulating the secretion of cytokines. Natural killer T cells participate in the immune regulation generally. Focus on recent years found that natural killer T cells played important roles in Thl/Th2 imbalance and airway hyper responsiveness (AHR) of asthma. This paper reviewed the progress of the characteristics of natural killer T ceils and the association with bronchial asthma.
