Regulation of cholecystokinin release from central nerve terminals.
The high abundance of the cholecystokinin octapeptide in various brain regions is expressed by involvement of this neuropeptide in diverse brain functions. This peptide is mostly, if not always, co-localized with classic transmitters in central nerve terminals. Since the functions of the coexisting transmitters are often different, differential regulation of their release is obvious. This differentiation is realized by differences in presynaptic localization, release dynamics, and calcium regulation. In addition, CCK release is locally modulated by receptors, kinases and phosphatases. The regulatory mechanisms of CCK release are placed into physiological perspective.
