Localization of cholecystokinin A and cholecystokinin B-gastrin receptors in the human stomach

Gastroenterology, 1997
Gastrin and cholecystokinin (CCK) are gut-brain peptides, with multiple functions in the gastrointestinal tract mediated through CCK-B-gastrin and CCK-A receptors. The receptor localization is, however, not well established in humans. The aim of this study was to investigate the distribution and pharmacological characteristics of CCK-A and CCK-B ...

The cholecystokinin receptor antagonist CR1409 increases plasma cholecystokinin in rats

Regulatory Peptides, 1989
This study was undertaken to determine whether plasma cholecystokinin (CCK) levels are affected by the administration of the CCK-receptor antagonist CR1409 to rats. Infusion of 0.19, 0.94 and 4.75 mg/kg.h CR1409 for 30 min each into 6 conscious rats increased (P less than 0.05) plasma CCK from 1.3 +/- 0.5 to 6.0 +/- 1.2, 5.4 +/- 1.2, and 5.4 +/- 1.0 pM,

Purification of the Cholecystokinin Receptor

1990
Cholecystokinin (CCK) is a gastrointestinal and neural peptide hormone with physiological activities at multiple target tissues (Mutt, 1980). These include the classical targets of the gallbladder muscularis smooth muscle and the pancreatic acinar cell (for which this hormone was named “cholecystokinin-pancreozymin”) (Ivy and Oldberg, 1928; Jorpes and ...

Cholecystokinin-dopamine receptor interactions as studied with cholecystokinin receptor antagonists.

Progress in clinical and biological research, 1986
It has previously been shown that cholecystokinin octapeptide (CCK-8) can modulate the binding of dopaminergic agonists and antagonists to brain homogenates in vitro. The present study was designed to more carefully address the possibility that CCK-8 could modulate the number of affinity of rat striatal D2 receptors.

[Receptors for cholecystokinin and gastrin].

Zeitschrift fur Gastroenterologie, 1999
Cholecystokinin (CCK) and gastrin belong to one family of gastrointestinal peptides that regulate a variety of functions in the gastrointestinal tract and in the central nervous system. On the basis of pharmacological, physiological and molecular studies, receptors for these peptides can be divided into at least two different types: CCKA- and CCKB ...

Pyloric Cholecystokinin Receptors

1991
Central or peripheral administration of the brain gut peptide cholecystokinin (CCK) results in a range of biological actions. CCK binding sites at which these actions may be mediated have been identified in multiple brain regions and at various sites in the gastrointestinal tract.
