Branchial Chloride Cells in Larvae and Juveniles of Freshwater Tilapia 0re0chr0m1s Mossambicus

Acclimation responses of gill ionocytes of red tilapia (Oreochromis mossambicus × O. niloticus) to water salinity and alkalinity

To understand the acclimation strategies of red tilapia to different environments, this study aimed to evaluate different responses of red tilapia (O. mossambicus × O. niloticus) to salinity (10-30‰), alkalinity (1-3 gL-1 NaHCO3) and salinity and alkalinity (10/1-30/3 ‰/gL-1NaHCO3) environments. Localization, type, size, and numeration of gill ionocytes were investigated on the sa...

NaCl uptake by the branchial epithelium in freshwater teleost fish: an immunological approach to ion-transport protein localization.

Teleost fishes, living in fresh water, engage in active ion uptake to maintain ion homeostasis. Current models for NaCl uptake involve Na(+) uptake via an apical amiloride-sensitive epithelial Na(+) channel (ENaC), energized by an apical vacuolar-type proton pump (V-ATPase) or alternatively by an amiloride-sensitive Na(+)/H(+) exchange (NHE) protein, and apical Cl(-) uptake mediated by an elect...

Expression of the Na-K-2Cl Cotransporter in Branchial Mitochondrion- Rich Cells of Mozambique Tilapia (Oreochromis mossambicus) Subjected to Varying Chloride Conditions

733 T he Na-K-2Cl cotransporter (NKCC) mediates the coupled movements of Na, K, and Clacross plasma membranes of animal cells. The NKCC plays an important role in ion movements across polarized epithelia and is also known to be involved in regulating cell volume and intracellular Cllevels (Lytle and Forbush 1996, Haas and Forbush 1998). The NKCC is a member of the Na-coupled group of cation-chl...
