| Outline of Final Research Achievements |
Galanin-like peptide (GALP) plays an important role of feeding regulation and energy metabolism. We have reported on neuronal circuits involving GALP in the hypothalamus. To identify afferent neurons of GALP neurons, we used transgenic mice co-expressing retrogradely transpoted tracer and beta-galactosidase under the control of GALP gene regulatory region using Cre-loxP recombination. Afferent neurons are present in the medial septal, medial habenular nucleus, anterodosal thalamic nucleus, medial preoptic nucleus, paraventricular hypothalamic nucleus, hypothalamic arcuate nucleus and Purkinje cells. These results suggest that GALP neurons function as a regulator of not only feeding and energy metabolism but also several physiological actions such as male-typical sexual behavior and reward system.
