Abstract/OtherAbstract:
|
Prolactin-releasing peptide (PrRP) was recently isolated from bovine hypothalamus. PrRP is the natural ligand for an orphan G-protein-coupled receptor, hGR3, and directly stimulates prolactin secretion from the anterior pituitary in vitro and in vivo. It has also been reported that PrRP plays an important role as a neurotransmitter and/or neuromodulator in the brain. Although much knowledge has been gained concerning PrRP in the adult rat brain, little attention has been paid to the fetal and postnatal stages. We therefore examined the development of PrRP neurons in the rat brain. In immunocytochemical and in situ hybridization experiments, we observed the transient appearance of PrRP-producing cells in the area postrema (AP), in which PrRP-producing cells do not exist in the normal adult rat. PrRP-producing cells in the AP were detected at P14, and many PrRP-producing cells were observed at P17, though none were detected at P19. This is the first report of the appearance of PrRP-producing cells in the postnatal AP. Our findings suggest that PrRP may play a previously unknown role in the AP of postnatal rats. |
