This issue of Peptides was inspired by a gathering of CCK researchers at the first Neuronal Cholecsytokinin Gordon Conference. The papers in this issue reflect the diversity of CCK research and demonstrate how the field has matured. Reviews describe the regulation of CCK gene expression and CCK release, the nature of the hormone binding site of the CCK A receptor, interaction of CCK, dopamine and GABA, the role of CCK in thermoregulation, sexual behavior and satiety in rodents and humans. The research articles document features of cardiovascular regulation, reduced cocaine sensitization and decreased satiety in rats that lack the CCK A receptor. Pro CCK processing in neuroblastoma cells and the elevation of CCK levels in CSF in a model of chronic pain are detailed in other articles. Three articles using different behavioral paradigms in rat and sheep examine CCK in learning and memory. Two articles that examine CCK in different behaviors that have a dopaminergic component are included. Other articles describe the interaction between a 5HT 3 antagonist and CCK-induced satiety and c-fos activation and document secretion of oxytocin and vasopressin in female patients and controls in response to CCK 4 administration. There is good reason to believe that the future is bright for research on CCK. With the organization of national and international meetings, CCK researchers have a forum for communication. Opportunities for cooperation and collaboration have never been better. The easy integration of academic basic and clinical science with industrial science bodes very well for the advancement of our understanding of the multiple roles that CCK plays in the brain and for the future development of CCK-based therapies.
