VIP(血管活性肠肽)是多种对动物呼吸道粘膜的粘液分泌和纤毛运动具有调节功能的神经肽类物质之一。以往的研究曾提示VIP对粘膜纤毛功能的影响是由于增加了气道分泌物和上皮细胞的离子转运、改变了纤毛摆动的环境而实现的。亦有人认为这种作用不是直接的,因为VIP与乙酰胆碱均贮存在蝶腭神经节中的神经细胞体内,在副交感神经节前纤维受到刺激后伴随着乙酰胆碱的释放而出现,动物实验曾表明在猫的颌下腺受到乙酰胆碱作用的 VIP (vasoactive intestinal peptide) is one of several neuropeptides that regulate the mucus secretion and ciliary motility of animal respiratory mucosa. Previous studies have suggested that the effects of VIP on mucociliary function are due to increased ion transport of airway secretions and epithelial cells, altering the ciliary wobble environment. Some people think that this effect is not direct, because VIP and acetylcholine are stored in the nerve cells in the sphenopalatine ganglion in parasympathetic preganglionic fibers stimulated with the release of acetylcholine appear, animal experiments have shown that cats The submandibular gland is affected by acetylcholine
