title: Peptidergic innervation of the rat Harderian gland.
abstract: The immunohistochemical localization of vasoactive intestinal polypeptide (VIP), Neurotensin (NT), cholecystokinin (CCK), Neuropeptide Y (NPY), and calcitonin-gene-related peptide (CGRP) in rat Harderian glands was examined. Numerous VIP- and CCK-like immunoreactive nerves were found in close apposition to the acini. Sparse numbers of NT-, NPY-, and CGRP-like immunoreactive nerves were observed in close proximity to the acini and blood vessels. Some VIP-like immunoreactive nerves were shown to be co-localized with acetylcholinesterase-positive cholinergic nerves.
