Neuroepithelial bodies in the lung of Basiliscus vittatus (Reptilia, Iguanidae)

Abstract

Beyond the confirmation that morphology, content of biologically active substances such as serotonin and calcitonin, and innervation are evolutionary well preserved features of NEB, the results reveal some intriguing features of B. vittatus NEB: strict separation of calcitonin and CGRP, reduced need for the de-ubiquitinating enzyme PGP 9.5, lack of luminal contact, and the basket-like innervation. The latter two properties possibly refer to a mechanoreceptor function of NEB in this species.
