近年来积累的信息已经开始揭示以前未被怀疑的肺神经支配的复杂性。我们现在知道,传导性气道接受高度冗余的迷走神经运动和感觉纤维的供应;这些纤维中的许多纤维从大脑的对侧穿过到达肺的远侧部分,从而确保支气管反应的对称性和稳定性;并且,可能认识到近端和远端气道的不同功能和特性,迷走运动纤维具有独特的节段性分布。感觉神经元和运动神经元作为复杂脑干神经元网络的输入和输出元件,其将气道平滑肌张力的调节整合到通气的控制中。该网络在气道壁中具有局部对应物,其中异质性固有神经元群体不仅可以作为胆碱能刺激的中继,而且还可以作为炎症调节的局部机制。对肺的神经供应的中断(例如在肺移植后)消除了支气管扩张和呼吸活动的整合,并且通过增加气道变形,可能引发气道壁中的纤维增生反应。此外,迷走神经运动和感觉纤维的破坏留下了失神经支配的内源性神经元的存活群体,这可能是炎症放大的失调机制。
Information accumulated in recent years has begun to unveil a previously unsuspected complexity in the innervation of the lungs. We know now that the conducting airways receive a highly redundant supply of vagal motor and sensory fibers; that many of these fibers cross over from the contralateral side of the brain to reach distant portions of the lung, thereby assuring the symmetry and simultaneity of the bronchomotor responses; and that, perhaps in recognition of the different functions and properties of proximal and distal airways, vagal motor fibers have a distinctive segmental distribution. Both sensory and motor neurons serve as the input and output elements of a complex brain stem neuronal network, which integrates the regulation of airway smooth muscle tone into the control of ventilation. This network has a local counterpart in the airway walls, where a heterogeneous population of intrinsic neurons may act not only as a relay for cholinergic stimuli, but also as a local mechanism of inflammatory modulation. The interruption of the nerve supply to the lungs (for instance after lung transplantation) abolishes the integration of bronchomotor and ventilatory activities, and, by increasing airway deformation, may initiate fibroproliferative responses in the airway walls. In addition, the destruction of vagal motor and sensory fibers leaves behind a surviving population of denervated intrinsic neurons, which may act as a disregulated mechanism of inflammatory amplification.
