title: Cytochemical study of prolactin-releasing peptide (PrRP) in the rat brain.
abstract: Strong positive signals for PrRP mRNA and PrRP-like immunoreactivity (PrRP-LI) were detected in the nucleus of the solitary tract and ventral and lateral reticular formation of the caudal medulla oblongata. Weak mRNA signals and immunoreactivity were seen scattered from the hypothalamic dorsomedial nucleus (DMH) to ventromedial nucleus (VMH). Nerve processes and terminals with PrRP-LI were detected from the septal region to the diencephalon. These nerve processes were also clearly visible around capillary walls and in the vicinity of the ependymal cells of the third and lateral ventricles. These observations suggested that PrRP might be secreted into the systemic circulation and cerebrospinal fluid and may play functional roles other than in the release of prolactin from the anterior pituitary.
