High impact information on CCKBR

  • The neurogenic vasodilatation induced by CCK-4 was blocked by the CCK2R antagonist, L-365,260, and antagonized by neuronal NO synthase (nNOS) inhibitors, but was independent of the endothelium [1].
  • The authors report that cholecystokinin (CCK), via its subtype 2 receptor (CCK2R) located presynaptically on cerebral arteries, mediates the release of nitric oxide (NO), which induces vasodilatation [1].
  • Pharmacological analysis using selective agonists and antagonists indicated the expression of the CCK-A receptor at birth, whereas the CCK-B receptor predominated at postnatal stages [2].
  • The effect of luminal gastrin on the secretion of pancreatic juice was studied in seven conscious preruminant calves employing luminal infusions of gastrin and cholecystokinin (CCK)-9 and pharmacological CCK1 and CCK2 receptor blocks with antagonists [3].
  • The effect of caerulein was antagonized by devazepide, a selective CCKA-receptor antagonist, but not by L-365.260, a selective CCKB-receptor antagonist [4].
