哮喘的发病和治疗都与β肾上腺素受体(简称β受体)有密切关系。本文以呼吸道的β受体为主,介绍β受体与哮喘之间关系的研究进展。呼吸道内β受体特点及其功能呼吸道β受体亚型β_1与β_2受体在许多组织内同时并存,但在各器官或其不同部位中,β_1和β_2受体比率差异很大。两个亚型有时还可以互相转化。表1列出人及动物呼吸道β受体的亚型。呼吸道β受体功能呼吸道不同效应细胞的β受体功能归纳见 The pathogenesis and treatment of asthma and β-adrenergic receptor (referred to as β receptor) are closely related. In this paper, the respiratory receptor β-based, introduced the relationship between β-receptor and asthma research progress. Characteristics and Function of β Receptor in Respiratory Tract The β 1 and β 2 receptors of the β receptor subtype of the respiratory tract coexist in many tissues at the same time. However, the ratio of β 1 and β 2 receptors varies greatly in different organs or different parts. Two subtypes can sometimes transform each other. Table 1 lists the human and animal respiratory beta receptor subtypes. Respiratory β receptor function of different effector cells of the airway β receptor function see
