Cholecystokinin (CCK) peptides are involved in the control of multiple functions both in the central nervous system (CNS) and in the gastrointestinal tract where they act as neurotransmitters and regulate digestive functions. This review deals with the role of CCK peptides as vasoactive mediators. Recent work from our group demonstrates that CCK peptides induce neurogenic vasodilatation both in cerebral and mesenteric vessels. Such an effect is mediated by nitric oxide and seems to be presynaptic. These findings suggest that endogenous CCK peptides could be relevant vasodilatory agents involved in regulating both cerebral and splanchnic blood flow. We hypothesize here how such an effect could be useful in the interpretation of, in a new conceptual frame, the eventual contribution of CCK to some physiological and physiopathological events, such as splanchnic postprandial hyperaemia, panic attack or migraine.
