title: Innervation of the chicken parathyroid glands: immunohistochemical study with the TuJ1, galanin, VIP, substance P, CGRP and tyrosine hydroxylase antibodies.
abstract: The innervation of the chicken parathyroid glands was studied by immunohistochemistry using various antibodies. The parathyroid glands, as well as the carotid body and ultimobranchial gland, received branches originating from the vagus nerve. Numerous nerve fibers immunolabeled with the monoclonal antibody (TuJ1) against neuron-specific class III beta-tubulin isotype were found in the connective tissue capsule and septa penetrating into the parathyroid parenchyma. They were also prominent in the wall of blood vessels. Peptidergic nerve fibers immunoreactive for galanin, vasoactive intestinal polypeptide (VIP), substance P and calcitonin gene-related peptide (CGRP) were densely distributed in the capsule, septa and blood vessel walls of the parathyroid glands. In addition, some TuJ1-, substance P- and CGRP-immunoreactive fibers were detected in close association with the parenchymal cells of parathyroid glands. Tyrosine hydroxylase-immunoreactive fibers were concentrated around blood vessels and also in connective tissue stroma.
