Pulmonary calcitonin gene-related peptide immunoreactivity: nerve-endocrine cell interrelationships.

Respiratory epithelium has been reported to be supplied with sensory nerves and to contain irritant and other receptors. In this immunohistochemical study, we examined the incidence, morphology, and distribution of calcitonin gene-related peptide (CGRP) immunoreactivity in epithelial cells the rat respiratory tract, using peroxidase anti-peroxidase (PAP… CONTINUE READING
