Abstract
Localization and gene expression of pituitary adenylate cyclase activating polypeptide receptor (PACAPR) in the rat retina were studied by immunocytochemistry and in situ hybridization, respectively. Antisera were raised against a synthetic peptide that corresponds to the carboxy-terminal cytoplasmic domain which is found in all subtypes of PACAPR. Strong PACAPR mRNA expression and PACAPR-like immunoreactivity (PACAPR-LI) were detected in ganglion cells, amacrine cells, and in the inner plexiform layer. PACAPR-LI appeared to be concentrated predominantly in the neuronal perikarya and processes. At the ultrastructural level, strong immunostaining for PACAPR was visible in the plasma membranes, rough endoplasmic reticulum and cytoplasmic matrix in neurons. This study provides the basis for a better understanding of the functions of PACAP in the rat retina.
