Immunocytochemistry and radioimmunochemistry demonstrate the occurrence of the gastrointestinal hormone cholecystokinin (CCK) in both the central and peripheral nervous system of the guinea pig. CCK nerves are particularly numerous in the neocortex, the hippocampus, the amygdaloid nuclei, the hypothalamus, the spinal cord and in the colon. The nerves contain 5 molecular components of CCK, with gel chromatographical elution constants (Kav) of 0.05, 0.50, 0.90, 1.10 and 1.30, respectively. The 4 latter correspond to triacontatripeptide CCK and its COOH-terminal dodeca-, octa- and tetrapeptide portions, respectively. Cholecystokinins are widely distributed in the nervous system and occur in substantial quantities (.gtoreq. 0.2 nmol CCK-8-equiv./g) in several distinct regions.
