General description

Research area: Immunology & cytokines

Application

Pentagastrin has been used to bidirectionally modulate lateral nucleus of the amygdala (LA) activity. It has also been used as a cholecystokinin-2 receptor (CCK2R) agonist to block the receptor binding for Ga-DOTA-MGS5 in AR42J rat pancreatic cell lines during cell uptake and receptor binding studies.

Biochem/physiol Actions

Pentagastrin, a synthetic polypeptide is a gastrin analog. It contains the five C-terminal amino acids of gastrin. It acts as a cholecystokinin-2 (CCK2) receptor/ cholecystokinin-B (CCKB) receptor agonist. Pentagastrin stimulates the secretion of pepsin and gastric acid. It also aids in the evaluation of gastric acid secretory function. Pentagastrin exhibits panicogenic/ anxiogenic effects and thereby induces panic attacks in panic disorder (PD) patients.
