Compartmentalized and signal-selective gap junctional coupling in the hearing cochlea [PDF]
Gap junctional intercellular communication (GJIC) plays a major role in cochlear function. Recent evidence suggests that connexin 26 (Cx26) and Cx30 are the major constituent proteins of cochlear gap junction channels, possibly in a unique heteromeric ...

[Pathophysiological aspects of K+: Cl- cotransporters].
The K+:Cl- cotransporters or KCCs are membrane proteins that move K+ and Cl- ions across the membrane without changing the transmembrane potential. KCCs belong to the SLC12 (Solute Carrier Family 12) family of electroneutral cation-chloride cotransporters (CCC), and they are secondary active ion transporters because use the established gradients from ...

Spreading depolarization and its influence on epileptiform activity
Abstract Spreading depolarization (SD) is a transient disruption of electrographic activity that slowly propagates through the gray matter by chemical contiguity, and it is characterized by a large depolarization of neurons and glial cells. SD, which is associated with massive changes in ion homeostasis, including extreme increases in [K+]o, was shown ...

The essential roles of metal ions in insect homeostasis and physiology [PDF]
Metal ions play distinct roles in living organisms, including insects. Some, like sodium and potassium, are central players in osmoregulation and ‘blood and guts’ transport physiology, and have been implicated in cold adaptation.

Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Renal phosphaturia during metabolic acidosis revisited: molecular mechanisms for decreased renal phosphate reabsorption [PDF]
During metabolic acidosis (MA), urinary phosphate excretion increases and contributes to acid removal. Two Na+-dependent phosphate transporters, NaPi-IIa (Slc34a1) and NaPi-IIc (Slc34a3), are located in the brush border membrane (BBM) of the proximal ...

This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Functionally Important Residues in the Predicted 3rd Transmembrane Domain of the Type IIa Sodium-phosphate Cotransporter (NaPi-IIa) [PDF]
The type IIa Na+/Pi, cotransporter (NaPi-IIa) mediates electrogenic transport of three Na+ and one divalent Pi ion (and one net positive charge) across the cell membrane.

Na/K/Cl cotransport in cultured human fibroblasts.
The transport characteristics and regulation of the Na/K/Cl cotransport system were investigated in cultured human fibroblasts (HSWP cells). The existence of the system was documented by the finding that digitoxin-insensitive K+ influx was dependent upon the presence of both Na+ and Cl- in the extracellular milieu.
