Importance of melanocortin signaling in refeeding-induced neuronal activation and satiety.


To identify regions in the hypothalamus involved in refeeding and their regulation by alpha-MSH, adult rats were subjected to a 3-d fast, and 2 h after refeeding, the distribution of c-Fos-immunoreactive neurons was elucidated. Compared with fed and fasted animals, a significant increase (P < 0.001) in the number of c-Fos-immunoreactive cells was identified… (More)
