生物活性
描述 Pituitary adenylate cyclase-activating polypeptide (PACAP), belonging to the neuropeptide family, functions as a hypophysiotropic hormone, neurotransmitter and neuromodulator and plays a critical role in neurogenesis[1]. As a fragment of pituitary adenylate cyclase activating polypeptide, PACAP (1-38), human, ovine, rat binds to PACAP type I receptor, PACAP type II receptor VIP1, and PACAP type II receptor VIP2 with IC50s of 4 nM, 2 nM, and 1 nM, respectively[2]. In vitro, PACAP (1-38) relaxed guinea-pig and rabbit tracheal smooth muscle precontracted by histamine and by acetylcholine[3]. In vivo, PACAP (1-38) dissolved in solutio ophthalmica cum benzalkonio led to significant protection in the retina in bilateral common carotid artery occlusion (BCCAO)-lesioned retinas; retinas treated with PACAP (1-38) eye drops had preserved structure compared to control retinas[4].
