title: The effects of immunization against cholecystokinin fragment 30-33 in the behavior of white rats.
abstract: Active immunization of white rats with cholecystokinin-4 covalently linked to the antigen carrier BSA evoked long-lasting changes in the rats' behavior, which were in the opposite direction to the anxiogenic effects of cholecystokinin-4 itself, showing that immunization had anxiolytic effects. Immunoenzyme analysis demonstrated the presence of antibodies to cholecystokinin-4 in the serum of immunized rats. These data are interesting from the point of view of correcting pathological anxiety and fear states by inverse immunoregulation.
