胆囊收缩素（英语：cholecystokinin，简称CCK或CCK-PZ）是一种脑肠肽，主要功能是促进脂肪和蛋白质的消化。其名称源自希腊语，包含chole（胆汁）、cysto（囊状）和kinin（移动）三个部分，整体意为“移动胆汁之囊”。它不仅在消化系统中广泛存在，还在中枢及外周神经系统中发挥作用^[5]。

胆囊收缩素在此之前名为促胰酶素（pancreozymin），是由小肠的黏膜上皮细胞当中的I细胞所合成，并由十二指肠分泌。当胆囊收缩素被分泌出来后，会刺激胰脏和胆囊分别释放消化酶和胆汁，以帮助消化过程。

除了在消化过程中发挥作用，胆囊收缩素还是一种食欲抑制剂。当胆囊收缩素在体内水平升高时，可以抑制食欲，帮助控制食物的摄入量。最近的证据暗示，胆囊收缩素在促进鸦片类药物的药物容许量，如吗啡和海洛因，扮演著重要角色，并且在经历鸦片类药物停药后的疼痛过敏经历有著部份的关联性^[6]^[7]。

胆囊收缩素基因最早在狗（Canis lupus familiaris）的胃肠道中被发现^[8]，随后在人类（Homo sapiens）、小鼠（Mus musculus）、虹鳟（Oncorhynchus mykiss）、大西洋鲑（Salmo salar）和团头鲂（Megalobrama amblycephala）等多个物种中也有发现^[5]。研究表明，不同动物中的胆囊收缩素存在两种甚至三种不同的亚型，并且它们的功能存在差异^[5]。例如，在虹鳟中存在CCK-L、CCK-N和CCK-T三种胆囊收缩素亚型，其中CCK-L亚型作为饱腹因子调节摄食，而CCK-N亚型则无显著作用^[9]。在红鲷（Pagrus major）中发现CCK基因存在CCK1和CCK2亚型，其中CCK1亚型在消化过程中发挥重要作用，CCK2亚型则通过向脑发送信号调节食物摄入和控制饱腹感^[10]。而在白鲷（Diplodus sargus）中，CCK1基因的表达水平不受摄食影响，CCK2基因则参与消化过程的负反馈调节^[11]。

胆囊收缩素基因通过与胆囊收缩素受体基因（Cholecystokinin receptor，简称CCKR）相结合，调节动物的摄食、消化等生理过程^[12]。在多数动物中，CCKR基因存在CCK1R和CCK2R两种亚型^[13]。研究显示，CCK与CCK1R基因结合主要影响消化系统，而CCK与CCK2R基因结合则主要影响中枢神经系统，二者共同参与摄食活动的调节过程^[14]。
