Abstract：
:Neuropeptide Y (NPY) and corticotropin-releasing factor (CRF) have opposing effects on stress-associated and consummatory behaviors in rodents. Recent studies also suggest that both peptides influence ethanol intake. In the present study, the effects of administration of CRF and NPY into the lateral ventricle on ethanol intake in naive and ethanol-vapor-exposed Wistar rats were examined. A limited access paradigm was used to measure intake of a 10% (v/v) ethanol solution in Wistar rats trained to drink using a sucrose fading procedure. Ethanol vapor exposure for 8 weeks significantly elevated ethanol intake in this limited access paradigm relative to pre-exposure levels. The effects of icv administration of CRF (1 microg), NPY (10 microg) or NPY/CRF combined (10 and 1 microg, respectively) on ethanol intake were then assessed. In non-vapor-exposed subjects, icv infusion of NPY had no effect on ethanol intake, while a significant suppression of drinking was seen following icv administration of CRF. Administration of NPY in combination with CRF had no effect on ethanol intake in non-ethanol-vapor-exposed rats. In vapor-exposed subjects, both NPY and CRF reduced ethanol intake, but when given in combination, no difference from vehicle was detected. Locomotor activity was measured during drinking sessions and was unaffected by peptide administration. These studies underscore the importance of a history of exposure to chronic ethanol vapor in the regulation of ethanol intake by NPY. Furthermore, the results presented here suggest that a balance between the stress-related peptides NPY and CRF may be involved in the regulation of ethanol intake.
