Interaction of CCK with pancreatic acinar cells

Abstract

Recent studies demonstrate that cholecystokinin-like peptides are widely distributed in the CNS as well as in the peripheral nervous system and gastrointestinal tract. Studies with agonists have demonstrated multiple classes of receptors and recently potent receptor antagonists have been described which will distinguish these classes and should allow a better understanding of the role of CCK in various physiological processes. One of the known peripheral physiological functions of CCK is the stimulation of digestive enzymes from pancreatic acinar cells. In recent years the interaction of CCK with pancreatic acinar cells has been extensively studied and significant advances have been made in understanding its cellular basis of action. Robert Jensen and colleagues report on each of these areas.
