WebBackground: The cholecystokinin (CCK) system has long been hypothesised to have a role in the pathogenesis of panic attacks. Previous research into genetic variation within the CCK gene and the genes for its two receptors, CCKAR and CCKBR, has produced mixed results. We aimed to clarify this association by investigating multiple variants within ... CCK plays important physiological roles both as a neuropeptide in the central nervous system and as a peptide hormone in the gut. It is the most abundant neuropeptide in the central nervous system. CCK has been researched thoroughly for its role in digestion and it participates in a number of processes such as digestion, satiety and anxiety. CCK is synthesized and released by enteroendocrine cells in the mucosal lining of the small int…
