Abstract

Osmoregulation is a major challenge in aquatic animals involving a complex endocrine control. We investigated the potential role of calcitonin gene-related peptide (CGRP, a neuromediator in mammals) in the endocrine control of the gill in a teleost, the eel. Transfer from freshwater to seawater induced an hyperosmolality and a concomitant large increase in plasma CGRP levels. Specific CGRP binding sites were characterized in the gill and their number was up-regulated after seawater transfer. This study suggests that the endocrine control of gill function during osmoregulation may represent an ancient role of CGRP in vertebrates.
