Biochem/physiol Actions

胆囊收缩素片段 30-33 酰胺也称为 CCK-4 或 Trp-Met-Asp-Phe 酰胺是衍生自肽激素胆囊收缩素的肽片段。CCK-4 是引起人惊恐发作的惊恐试剂。化合物的这种性质可用于测试新抗焦虑药的科学研究。CCK-4 通过CCK-B受体选择性地起作用,其在情绪性行为调节中的作用得到广泛认可。 CCK 敲低小鼠研究表明其具有抗焦虑和抗抑郁作用。

General description

研究领域:神经科学

大脑中具有神经肽胆囊收缩素(CCK)的多个生物活性片段,它们在大脑中与CCK-A和 CCK-B受体相互作用。 在这些片段中,CCK-4在皮层和脑边缘系统中含量特别丰富。作为胆囊收缩素的生物活性形式,CCK-4是一种肽激素,通过结合肠道和脑中的CCK受体来调节食物摄入。

Packaging
