In teleosts, mitochondrion-rich (MR) cells, or chloride cells, are importantly involved in
freshwater and seawater adaptation and acid-base regulation. In this paper, we reviewed …

August Krogh made fundamental discoveries about both respiratory gas exchange and
osmo/iono-regulation in fish gills. Dave Randall and co-workers identified a tradeoff …

Uptake of Na+ from the environment is an indispensable strategy for the survival of
freshwater fish, as they easily lose Na+ from the plasma to a diluted environment …

The importance of salt and water absorption from the food by the gastrointestinal tract and its
impact on iono-and osmoregulation have been largely overlooked by fish physiologists. The …

Mitochondrion-rich cells (MRCs), or ionocytes, play a central role in aquatic species,
maintaining body fluid ionic homeostasis by actively taking up or excreting ions. Since their …

For most of the last century, the need to obtain sufficient oxygen to meet the respiratory
requirements of the tissues was viewed as the primary selective pressure driving gill …

This review assembles recent information on seawater-type chloride cells of marine teleost
fish and evaluates the secretion of Na+, Cl−, K+, H+ and NH4+ and the absorption of Ca2+ …

Publisher Summary This chapter describes the ion transport and gill ATPases in the fish
gills. The gill epithelium is located between two liquid compartments of very different ionic …

We have explored the molecular basis for differences in physiological function between the
gills and opercular epithelium of the euryhaline killifish Fundulus heteroclitus. These tissues …

Cation–chloride cotransporters, such as the Na+/K+/2Cl–cotransporter (NKCC) and Na+/Cl–
cotransporter (NCC), are localized to the apical or basolateral plasma membranes of …
