  • Title: Gastrointestinal satiety signals II. Cholecystokinin.
    Author: Moran TH, Kinzig KP.
    Journal: Am J Physiol Gastrointest Liver Physiol; 2004 Feb; 286(2):G183-8. PubMed ID: 14715515.
    Abstract:
    During a meal, ingested nutrients accumulate in the stomach, with a significant portion passing on to the small intestine. The gastrointestinal presence of ingested nutrients initiates a range of physiological responses that serve to facilitate the overall digestive process. Thus peptides and transmitters are released, and various neural elements are activated that coordinate gastrointestinal secretion and motility and can eventually lead to meal termination or satiety. Among the range of gastrointestinal peptides released by ingested nutrients is the brain/gut peptide CCK. CCK plays a variety of roles in coordinating gastrointestinal activity and has been demonstrated to be an important mediator for the control of meal size.
