Novel cAMP signalling paradigms: therapeutic implications for airway disease.

abstract：BACKGROUND AND PURPOSE:Pituitary adenylate cyclase-activating polypeptide (PACAP) is an excitatory neuropeptide with central and peripheral cardiovascular actions. Intrathecal PACAP increases splanchnic sympathetic nerve activity and heart rate, but not mean arterial pressure (MAP). We hypothesize that the three PACAP ...
