WebDec 1, 2009 · The results indicate that there is a freshwater and a seawater isoform of NKA alpha-subunit in the gills of Atlantic salmon and that they are present in distinct chloride cells. Fig. 2. WebTransmission electron micrograph of the apical crypt of a chloride cell in a gill lamella of the sole, Solea solea. The crypt is bordered by pavement cells (pvc). An accessory cell (ac) beside the chloride cell sends out four processes (stars) which burrow into the protoplasm of the chloride cell. Junctions have formed between the pavement cell ...
WebAug 28, 2015 · The gills contain specialized pumping cells called chloride cells. The membranes of these cells contain molecular machines with the bulky name, Na+/K+ ATPase. We’ll call them NKA for short. As the … Webchloride cells Cells located in the gills of teleosts which pump sodium and chloride ions out into the sea against a concentration gradient. To reduce osmotic dehydration due to hyposmotic body fluid, teleosts drink large quantities of sea water, absorbing in the gut sodium and chloride ions which serve to raise the osmotic pressure in the blood and …
WebIn many chloride cells in seawater, NKA alpha1b was present in greater amounts in the subapical region than elsewhere in the cell. The combined patterns in abundance and immunolocalization of these two isoforms can explain the salinity-related changes in total NKA and chloride cell abundance. The results indicate that there is a freshwater and ... WebNov 1, 1993 · The apical membrane of the ionocytes – and there is general consensus that only these contribute to Ca 2+ transport in gills (Fenwick, 1989) – forms only a minor part of the total membrane surface facing the water (in the gills of freshwater tilapia the mature chloride cells in contact with the water make up less than 5% of the epithelial ...
WebIn the lateral half of the gill pouch, mitochondria-rich (MR) cells are intercalated between the pavement cells, which are characterized by an extensive amplification of the basolat-eral cell membrane and, in freeze-fracture replicas, by assemblies of linear arrays of particles and fibrils in the apical cell membrane.
