Cholecystokinin receptors

Cellular and Molecular Neurobiology, 1995
The cholecystokinin (CCK) and gastrin families of peptides act as hormones and neuropeptides on central and peripheral CCK receptors to mediate secretion and motility in the gastrointestinal (GI) tract in the physiological response to a normal meal. CCK and its receptors are also widely distributed in the central nervous system (CNS) and contribute to

Cholecystokinin, cholecystokinin-A receptor and cholecystokinin-B receptor gene polymorphisms in Parkinson's disease

Pharmacogenetics, 2003
Cholecystokinin modulates the release of dopamine and dopamine-related behaviours in the mesolimbic pathway, where cholecystokinin and dopamine coexist in dopaminergic neurones. Because cholecystokinin and its receptors (A and B) have a functional interaction with dopaminergic neurotransmission, alterations in them may constitute a predisposition for ...

Cholecystokinin and Gastrin Receptors

Physiological Reviews, 2006
Cholecystokinin and gastrin receptors (CCK1R and CCK2R) are G protein-coupled receptors that have been the subject of intensive research in the last 10 years with corresponding advances in the understanding of their functioning and physiology. In this review, we first describe general properties of the receptors, such as the different signaling ...

Cholecystokinin receptor antagonists

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1984
Since 1979 three classes of cholecystokinin receptor antagonists have been described: 1) derivatives of cyclic nucleotides, 2) derivatives of amino acids, and 3) C-terminal fragments or partial sequences of cholecystokinin. These various antagonists share a number of common features, such as their specific, reversible, and competitive actions, but ...

Role of cholecystokinin-A and cholecystokinin-B receptors in anxiety

Amino Acids, 2002
Evidence from several laboratories indicates that the anxiogenic effects of cholecystokinin (CCK) are mediated by CCKB receptors. However, it has been reported that CCKA receptors have been found in brain and CCKA antagonists have anxiolytic properties.

Dopamine receptor elevation by cholecystokinin

Peptides, 1984
High concentrations of cholecystokinin (CCK) in the striatum and limbic areas of the brain suggest that this peptide may influence dopaminergic transmission. Thus, the effect of CCK on dopamine D2 receptors in the striatum and nucleus accumbens of the rat brain both in vitro and in vivo (central and peripheral administration) was studied by determining
