Abstract
Na+/H+ exchange has been implicated in models of ion transport across the branchial epithelium of marine and freshwater fishes. In this preliminary study, we present immunohistochemical data using a polyclonal antibody raised against NHE3 which show NHE3-like immunoreactivity (IR) in the gills from a freshwater and a marine teleost species. In both species, branchial epithelial cells demonstrating NHE3-like IR were localised predominantly to the junction between the filament and the secondary lamellae. However, there was a marked difference in the morphology of the NHE3-like immunoreactive epithelial cells between the species. This morphological difference between the species suggests functional differences in the exchanger, which may be related to marine versus freshwater environments.
