CCK2 receptor

The gastrin receptor, known as CCK receptor 2 (CCK2R), is a seven transmembrane GPCR. Human CCK2R is 447 aa residues in length. CCK, non-sulfated CCK, gastrin, and non-sulfated gastrin bind to CCK2R with similar affinity and potency [6] CCK 2 Receptors. The cholecystokinin 2 receptor (CCK 2 receptor, CCK-B receptor) is a member of the cholecystokinin receptor group of G-protein-coupled receptors that also includes CCK 1. They are located primarily in the brain, spinal cord and stomach and influence neurotransmission The CCK2 receptor antagonists YF476, YM022, RP73870, JB93182 and AG041R were found to cause prompt inhibition of ECL-cell histamine and pancreastatin secretion and synthesis. The circulating pancreastatin concentration is raised, was lowered when the action of gastrin on the ECL cells was blocked by the CCK2 receptor antagonists Cholecystokinin receptors or CCK receptors are a group of G-protein coupled receptors which bind the peptide hormones cholecystokinin (CCK) and gastrin. There are two different subtypes CCK A and CCK B which are ~50% homologous : [2] Various cholecystokinin antagonists have been developed and are used in research, although the only drug of this class that has been widely marketed to date is the anti-ulcer drug proglumide The CCK 2 receptor is more abundant and widely distributed in the brain than the CCK 1 receptor, although distinct populations of the CCK 1 receptor are present. The CCK 1 receptor is present on soma and fibers in the SN, VTA, nucleus accumbens (Acb), and dorsal striatum but not in the prefrontal Cx, Amy, or Hi

  6. Gastrin/cholecystokinin subtype 2 receptors (CCK-2Rs) are overexpressed in several tumor types and are, thus, a potential target for peptide receptor radionuclide therapy (PRRT) of cancer. To improve the in vivo performance of CCK-2R binding peptides, we have previously synthesized and screened a series of divalent gastrin peptides for improved biochemical and biologic characteristics
  7. Together, our data demonstrate that intra-CeA CCK infusion activated a descending CCK2 receptor-dependent pathway that inhibited spinal neuron discharge. Thus, persistent pain induces a functional switch to a newly identified analgesic capacity of CCK in the amygdala, indicating central emotion-related circuit controls pain transmission in spinal cord

Cholecystokinin (CCK) Stimulates Aldosterone Secretion

How was the CCK2 receptor antibody specificity verified, and which cell type in Barrett's mucosa expressed the receptor? The clinical importance of gastrin-induced migration and proliferation in a cell line with transfected CCK2 receptor depends entirely on whether mucosal cells in Barrett's oesophagus express this receptor. Directly relevant. For CCK+ basket cells, CCK2 receptors in neighboring pyramidal cells act through the Gq pathway to form endocannabinoids, which, through the cannabinoid receptor type 1 on the CCK+ basket cell, inhibit the release of the neurotransmitter GABA. In contrast, for PV+ basket cells, CCK2 receptors act through the pertussin-toxin sensitive Gi pathway.

  4. Radiolabeled cholecystokinin-8 (CCK8) peptide analogues can be used for peptide receptor radionuclide imaging and therapy for tumors expressing CCK2/gastrin receptors. Earlier findings indicated that sulfated CCK8 (sCCK8, Asp-Tyr(OSO3H)-Met-Gly-Trp-Met-Asp-Phe-NH2) may have better characteristics for peptide receptor radionuclide therapy (PRRT) than gastrin analogues. However, sCCK8 contains.
  5. The authors report that cholecystokinin (CCK), via its subtype 2 receptor (CCK 2 R) located presynaptically on cerebral arteries, mediates the release of nitric oxide (NO), which induces vasodilatation. Whereas CCK octapeptide and its fragment CCK tetrapeptide (CCK-4) lack a direct effect on the smooth muscle of pial vessels, the authors showed that both CCK peptides modulate the neurogenic.

Gastrin exerts an antiproliferative and proapoptotic effect on human colon cancer cells expressing the wild-type CCK2 receptor. PMID: 16143134; The expression rates of gastrin and gastrin receptor are high (about a half) in gastric carcinoma tissues, and there is an association between gastrin and gastrin receptor expression Two main types of receptors for gastrin and cholecystokinin (CCK) have been cloned and identified [1-4], the CCK1-receptor (formerly named CCK-A receptor) which is expressed in the pancreas, the gallbladder and parts of the brain, whereas the CCK2-receptor (formerly named CCK-B/gastrin receptors) is expressed in gastric glands and in most of the brain [1-5] The present study supports a role of CCK2 receptors in the regulation of dopamine neurones. In pharmacological studies conducted on male CCK2 receptor-deficient mice the changes in the activity of dopamine system were established. A low dose of dopamine agonist apomorphine (0.1 mg/kg), stimulating the pre-synaptic dopamine receptors, induced significantly stronger suppression of locomotor.

Rationale Evidence suggests that GABA and CCK have opposite roles in the regulation of anxiety. Objective The aim of the present work was to study diazepam-induced anxiolytic-like action and impairment of motor co-ordination, and the parameters of benzodiazepine receptors in mice lacking CCK2 receptors. Methods The action of diazepam (0.5-3 mg/kg IP) was studied in the elevated plus-maze. CCK2 receptor activation causes anxiogenic effects while the blockade of this receptor has anxiolytic effects.
