Cholecystokinin (CCK) is a neurotransmitter found in high density in the brains of mammals. Microiontophoretic studies showing that benzodiazepines selectively antagonized CCK-induced excitation of rat hippocampal neurons have led to the hypothesis that CCK is an anxiogenic peptide. The hypothesis was supported by demonstrations that CCK-tetrapeptide (CCK4) induces panic attacks in humans. This paper reviews phases of investigations which studied the validity of CCK4 as a panicogenic agent and research strategies for the study of panic disorder using CCK4 as an investigative tool.
胆囊收缩素(CCK)是一种在哺乳动物大脑中高密度存在的神经递质。微离子电泳研究表明,苯二氮䓬类药物可选择性拮抗CCK诱导的大鼠海马神经元兴奋,这导致了一种假说,即CCK是一种致焦虑肽。CCK四肽(CCK4)可诱发人类恐慌发作的证据支持了这一假说。本文回顾了研究CCK4作为致恐慌剂有效性的各个研究阶段,以及使用CCK4作为研究工具来研究恐慌症的研究策略。
