R. Uddman et al., Expression of NPYY1 and CGRP1 receptors in human nasal mucosa: Implications in allergic rhinitis, ANN OTOL RH, 108(10), 1999, pp. 969-973
Numerous nerve fibers containing neuropeptide Y (NPY) and calcitonin gene-r
elated peptide (CGRP) have been found in the human nasal mucosa by means of
immunocytochemistry. We detected NPY Y1 and CGRP1 receptors at the same lo
cation using reverse transcriptase-polymerase chain reaction. The possibili
ty of local release in connection with specific target receptors suggests a
role for endogenous NPY and CGRP in the regulation of vascular tone, gland
ular secretion, and epithelial functions.
