Immunohistochemistry using whole section and whole mount preparation was applied
to establish the distribution of vasoactive intestinal polypeptide (VIP) nerve fibers in the
whole epithelial layers of the rat nasal mucosa. VIP nerve fibers run horizontally in the
basal region of the epithelial layers, sending off the branches toward the surface.
Intraepithelial VIP nerve fibers were predominantly found in some portions of the nasal
cavity, representing the region-specific distribution ; They were located in the mucosa
of nasal septum, the medial and Inferior surface of the maxilloturbinate and the superior
surface of the nasoturbinate. Interestingly, transepithelially extended fibers were
predominantly identified in the inferior surface of the maxilloturbinate and the superior
surface of the nasoturbinate. In addition, VIP immunoreactive perikarya was noted In the
small number of nerve cell bodies in trigeminal ganglion. Maxillary nerve section and
capsaicin treatment resulted in an disappearance of VIP nerve fibers from the epithelial
layers.
These findings Indicate that VIP nerves in the nasal epithelium of the rat are supplied
by trigeminal ganglion.
