The effect of calcitonin gene-related peptide (CGRP) on the smooth muscle of mammalian airways has been investigated in vitro. CGRP itself lacked contractile activity but reduced responses evoked by bronchoconstrictor agents via a post-junctional action. The inhibitory effect of CGRP was concentration-related and greatest in distal airways. The results suggest that CGRP may contribute to regulating muscular tone in the tracheobronchial tree.
降钙素基因相关肽(CGRP)对哺乳动物气道平滑肌的作用已在体外进行了研究。CGRP本身缺乏收缩活性,但通过接头后作用降低了支气管收缩剂引起的反应。CGRP的抑制作用与浓度相关,在远端气道中作用最强。结果表明,CGRP可能有助于调节气管支气管树的肌肉张力。
