Asthma, accompanied by lung inflammation, bronchoconstriction and airway hyper-responsiveness, is a significant public health burden. Here we report that Mas-related G protein-coupled receptors (Mrgprs) are expressed in a subset of vagal sensory neurons innervating the airway and mediates cholinergic bronchoconstriction and airway hyper-responsiveness. These findings provide insights into the neural mechanisms underlying the pathogenesis of asthma.
哮喘伴有肺部炎症、支气管收缩和气道高反应性，是一项重大的公共卫生负担。我们在此报告，Mas相关G蛋白偶联受体（Mrgprs）在支配气道的一部分迷走感觉神经元中表达，并介导胆碱能性支气管收缩和气道高反应性。这些发现为哮喘发病机制的神经机制提供了见解。
