摘要
支气管哮喘(以下简称哮喘)是一种在全球范围内发病率较高的慢性呼吸道疾病,近年来儿童哮喘发病率呈明显上升趋势.哮喘的发病机制极为复杂,目前未完全明确.研究表明,哮喘人群与健康人群的肠道菌群组成结构存在显著差异,肠道菌群可能通过调节T淋巴细胞亚群、树突状细胞、气道上皮细胞、黏膜免疫、相关信号通路等方式参与哮喘的发生和发展,而其代谢产物如短链脂肪酸、脂多糖、色氨酸、次级胆汁酸等也可能在哮喘发病中起着保护或促进的双重调控作用.本文就肠道菌群及其代谢产物在儿童哮喘发病机制中的研究进展进行综述.
Abstract
Bronchial asthma(hereinafter referred to as asthma)is a chronic respiratory disease with a high incidence rate worldwide.In recent years,the incidence rate of asthma in children has increased significantly.The pathogenesis of asthma is extremely complex,and it is not entirely clear.Studies have revealed that there is a significant difference in the composition structure of intestinal flora between asthma and healthy population,and intestinal flora may be involved in the occurrence and development of asthma through regulating T lymphocyte subsets,dendritic cells,airway epithelial cells,mucosal immune,related signaling pathways,and other approaches,whereas its metabolites such as short chain fatty acids,lipopolysaccharide,tryptophan,secondary bile acids may exert dual regulation effects of protection or promotion in the onset of asthma.In this review,research progress on intestinal flora and its metabolites in the pathogenesis of asthma in children is summarized.
