膽囊收縮素

膽囊收縮素(英語:cholecystokinin,簡稱CCK或CCK-PZ;詞源來自於希臘語的chole,膽汁之意;cysto,囊狀之意;kinin,移動之意;組合起來的意義為「移動膽汁之囊」)是一種消化系統當中的肽類激素,可以促進脂肪與蛋白質的消化。膽囊收縮素在此之前名為促胰酶素(pancreozymin),是由小腸的黏膜上皮細胞當中的I細胞所合成,並由十二指腸分泌;這會導致從胰臟與膽囊,各自釋放消化酶與膽汁。膽囊收縮素也是一種食欲抑制劑。最近的證據暗示,膽囊收縮素在促進鴉片類藥物的藥物容許量,如嗎啡和海洛因,扮演著重要角色,並且在經歷鴉片類藥物停藥後的疼痛過敏經歷有著部份的關聯性[1][2]。
