α2-肾上腺素受体(α2-ARs)广泛分布于中枢神经系统,包括与心肺控制相关的脑干部位。1,2一些证据有力地表明α2-ARs在调节呼吸节律中的作用。我们最近证明,全身给药可乐定和其他α2-AR激动剂会引起山羊呼吸模式的严重紊乱,其特征是呼吸急促和呼吸抑制交替发作(延长和可变的呼气时间间隔)。α2-AR激动剂诱导的山羊呼吸紊乱与喉部呼气相关驱动的持续紧张性激活4,5和咽部运动神经元6,8相关,导致中心性呼吸暂停时气道主动关闭6,8
α2-adrenoceptors (α2-ARs) are widely distributed in the CNS including brainstem sites associated with cardiorespiratory control.1,2Several lines of evidence strongly suggest a role for α2-ARs in the regulation of respiratory rhythm. We have recently demonstrated that systemic administration of clonidine and other α2-AR agonists cause profound disturbances in respiratory pattern in the goat that are characterized by alternating episodes of tachypnea and respiratory depression (prolonged and variable expiratory time intervals).3-8Dysrhythmic breathing induced by α2-AR agonists in the goat is associated with continuous tonic activation of expiratory-related drive in laryngeal4,5and pharyngeal motoneurons6,8leading to active airway closure during central apnea.6,8
