哮喘是一种慢性炎症性呼吸道疾病,其特征是对各种外源性刺激做出不同程度的气流阻塞。呼吸道上皮细胞是机体的第一道防线,在启动宿主防御和控制免疫反应中发挥着重要作用。事实上,越来越多的证据表明,哮喘上皮屏障功能的各个方面存在一系列异常。这种损害的核心部分是呼吸道上皮层的破坏,使吸入的物质更容易进入粘膜下层,在那里它们可能与免疫细胞相互作用。此外,许多已确定的哮喘易感基因在呼吸道上皮细胞中表达。本文就健康人的呼吸道上皮生物学及其在哮喘中的病理生物学作一综述。我们将专门讨论外部诱因,如过敏原、病毒和警报,以及2型炎症反应对哮喘气道上皮功能的影响。我们还将讨论在转录和转录后水平上对基因表达的转录和转录后调控做出反应的表观遗传学机制,以及作为哮喘潜在治疗靶点的呼吸道上皮细胞。
Asthma is a chronic inflammatory airway disease characterized by variable airflow obstruction in response to a wide range of exogenous stimuli. The airway epithelium is the first line of defense and plays an important role in initiating host defense and controlling immune responses. Indeed, increasing evidence indicates a range of abnormalities in various aspects of epithelial barrier function in asthma. A central part of this impairment is a disruption of the airway epithelial layer, allowing inhaled substances to pass more easily into the submucosa where they may interact with immune cells. Furthermore, many of the identified susceptibility genes for asthma are expressed in the airway epithelium. This review focuses on the biology of the airway epithelium in health and its pathobiology in asthma. We will specifically discuss external triggers such as allergens, viruses and alarmins and the effect of type 2 inflammatory responses on airway epithelial function in asthma. We will also discuss epigenetic mechanisms responding to external stimuli on the level of transcriptional and posttranscriptional regulation of gene expression, as well the airway epithelium as a potential treatment target in asthma.
