Abstract

The presence and localization of nerve growth factor receptors (NGFr) in the choroid plexus of the adult rat has been investigated immunohistochemically using an anti-rat NGFr monoclonal antibody (192-IgG). A moderate to strong immunoreaction was observed in the epithelial cells of the choroid plexus, whereas the choroidal blood vessels and connective tissue remained unlabelled. Moreover, no sex-differences were encountered in the NGFr immunoreaction intensity and Bouin fixative was more effective than 10% formaldehyde evidenciating the NGFr immunostain. Occasionally, ependymal cells displaying NGFr immunoreactivity were observed. Present data demonstrate that the choroid plexus of the rat contain NGFr, probably low-affinity NGFr, and suggest an involvement of NGF in the regulation of cerebrospinal fluid secretion, but the importance of these findings, if any, must be investigated in future studies.
