甘丙肽是一种属于神经肽家族的肽,存在于内分泌系统、中枢和外周神经系统中。它已被证明可以抑制中枢神经系统中乙酰胆碱的释放,有趣的是,在阿尔茨海默病患者中,已经发现甘丙肽纤维的神经支配过度。

Endogenous galanin receptor 激动剂。
Galanin (1-30), human 是由 30 个氨基酸构成的神经肽,为甘丙肽 GalR1 和 GalR2 受体的有效激动剂,Ki 值均为 1 nM。
Galanin (1-30), human is a 30-amino acid neuropeptide, and acts as an agonist of GalR1 and GalR2 receptors, with Kis of both 1 nM.
Galanin (1-30) (human)是具有多种内分泌,代谢和行为作用的内源肽。
甘丙肽是一种29或30个(人类)氨基酸的神经肽,存在于中枢和外周神经系统中,并显示出几种重要的生理活动。这些作用是通过不同的G蛋白偶联受体介导的。它涉及食物行为、睡眠和情绪调节、血压控制和伤害感受等。
Galanin, a 29 or 30 (in human) amino acid neuropeptide, is found in the central and peripheral nervous systems and displays several important physiological activities. These actions are mediated through distinct G protein-coupled receptors. It has been involved in food behavior, regulation of sleep and mood, control of blood pression and nociception, among others.
甘丙肽是一种属于神经肽家族的肽,存在于内分泌系统、中枢和外周神经系统中。它已被证明可以抑制中枢神经系统中乙酰胆碱的释放,有趣的是,在阿尔茨海默病患者中,已经发现甘丙肽纤维的神经支配过度。众所周知,甘丙肽具有多种生理作用,包括抑制胰岛素释放、刺激催乳素和生长激素分泌,在进食、情绪、认知、神经内分泌调节和影响胃肠运动方面也发挥作用。甘丙肽通过与G蛋白偶联受体结合来发挥其作用。
Galanin is a peptide that belongs to the family of neuropeptides and is found in the endocrine system, the central and peripheral nervous systems. It has been shown to inhibit the release of acetylcholine in the central nervous system and interestingly in Alzheimer’s disease patients, hyperinervation of galanin fibres has been found. Galanin is also known to have a variety of physiological effects including inhibition of insulin release, stimulation of prolactin and growth hormone secretion and it also plays a role in feeding, mood, cognition, neuroendocrine regulation and affects gastrointestinal motility. Galanin asserts its effects through associated with G-protein coupled receptors.
人甘丙肽最初是从结肠和垂体中分离出来的,它激活大鼠甘丙肽受体,抑制海马中乙酰胆碱的释放、谷氨酸的释放和卡巴胆碱刺激的磷脂酰肌醇水解。最近的研究表明,甘丙肽也与阿尔茨海默病的行为和认知缺陷有关。
Human galanin, originally been isolated from colon and pituitary, that activates the rat galanin receptor and inhibits acetylcholine release, glutamate release and carbachol-stimulated phosphatidylinositol hydrolysis in the hippocampus. Recent studies indicated that galanin is also linked to behavioral and cognitive deficits in Alzheimer’s disease.
