Abstract
The microbial composition and the functions of the respiratory tract and gut interact with each other, known as the " gut-lung" axis, which correlates with airway immune function.Airway epithelial barrier dysfunction and increased permeability contribute to antigen sensitization and progression of bronchial asthma (asthma) disease.At the same time, disrupted gut flora can increase the risk of asthma.Therefore, this review summarizes the normal structure and functions of the bronchial epithelial barrier and the role of the epithelial barrier damage in the pathogenesis of asthma.The regulation of airway epithelial barrier function by " gut-lung" axis imbalance reveals its relationship with asthma.Increased understanding of the changes in airway barrier and airway immune function caused by " gut-lung" axis imbalance will help clarify the close relationship between microecology and asthma.
Key words:
Asthma; Airway epithelialbarrier; Microbiome; "Gut-lung" axis
