  • 功能:
    This peptide hormone induces gall bladder contraction and the release of pancreatic enzymes in the gut. Its function in the brain is not clear. Binding to CCK-A receptors stimulates amylase release from the pancreas, binding to CCK-B receptors stimulates gastric acid secretion.
  • 基因功能参考文献:
    1. Study provides the first direct comparative and quantitative data showing that presynaptic GABAB receptors exert differential inhibition at cholecystokinin (CCK) and parvalbumin (PV) basket cell (BC) synapses, resulting from a higher surface expression of the receptor at all CCK BC terminals and a lower protein density present in a subpopulation of boutons of PV BCs. PMID: 28466358
    2. The two projections from CCK(NTS) neurons reduce food intake through opposite motivational states; one pathway signals positive valence (CCK(NTS)-->paraventricular nucleus of the hypothalamus ) and the other signals negative valence (CCK(NTS)-->parabrachial nucleus). PMID: 28684275
    3. Taken together, these results demonstrate that DMH NPY descending signals affect CCK-induced satiety, at least in part, via modulation of NTS catecholaminergic neuronal signaling. PMID: 27534875
    4. We conclude that only a small fraction of neuronal CCK is nonsulfated. The intracellular distribution of nonsulfated CCK in neurons suggests that they contribute only modestly to the CCK transmitter activity. PMID: 27535680
    5. The favorable treatment strategy for acute pancreatitis is to keep the pancreas at rest during an early stage followed by pancreatic stimulation by promoting endogenous CCK release. PMID: 26167074
    6. Cardiac expression of pro-cholecystokinin is cell-specific, which differentiates the expression from that of intestinal endocrine cells and cerebral neurons. PMID: 25627687

    12. Data suggest that Apo AIV (apolipoprotein AIV) in NTS (nucleus of the solitary tract) or/and peripheral Cck require vagal Cck1r (cholecystokinin receptor 1) signaling to elicit satiation; high-fat diet reduces satiating capacity of these signals. PMID: 24564397

    16. Rats on a medium high-fat diet had significantly higher plasma leptin but lower cholecystokinin levels than rats on a low-fat diet. This corresponded to attenuated or reversed splanchnic nerve responses to cholecystokinin and leptin. PMID: 21239630
    17. Unlike in the dorsal vagal complex (DVC), CCK-8 was only able to activate the myenteric neurons in older rats. This delayed activation compared to the DVC may reflect a delayed role for these neurons in CCK-related functions. PMID: 21093507
