Differential Assembly of Inwardly Rectifying K+ Channel Subunits, Kir4.1 and Kir5.1, in Brain Astrocytes [PDF]
The inwardly rectifying K+ channel subunit Kir5.1 is expressed abundantly in the brain, but its precise distribution and function are still largely unknown. Because Kir5.1 is co-expressed with Kir4.1 in retinal glial Muller cells, we have compared the biochemical and immunological properties of Kir5.1 and Kir4.1 in the mouse brain.

The central role of aquaporins in the pathophysiology of ischemic stroke [PDF]
Stroke is a complex and devastating neurological condition with limited treatment options. Brain edema is a serious complication of stroke. Early edema formation can significantly contribute to infarct formation and thus represents a promising target ...

Structural basis of control of inward rectifier Kir2 channel gating by bulk anionic phospholipids [PDF]
Inward rectifier potassium (Kir) channel activity is controlled by plasma membrane lipids. Phosphatidylinositol-4,5-bisphosphate (PIP(2)) binding to a primary site is required for opening of classic inward rectifier Kir2.1 and Kir2.2 channels, but ...

EAST syndrome: Clinical, pathophysiological, and genetic aspects of mutations in KCNJ10 [PDF]
EAST syndrome is a recently described autosomal recessive disorder secondary to mutations in KCNJ10 (Kir4.1), a gene encoding a potassium channel expressed in the brain, eye, ear and kidney.

An in vivo protein landscape of the mouse DCT during high dietary K+ or low dietary Na+ intake [PDF]
The hormone aldosterone is essential for maintaining K+ and Na+ balance and controlling blood pressure. Aldosterone has different effects if it is secreted due to hypovolemia or hyperkalemia.

High dietary potassium causes ubiquitin-dependent degradation of the kidney sodium-chloride cotransporter [PDF]
The thiazide-sensitive sodium-chloride cotransporter (NCC) in the renal distal convoluted tubule (DCT) plays a critical role in regulating blood pressure (BP) and K+ homeostasis.

Kir4.1 Potassium Channel Subunit Is Crucial for Oligodendrocyte Development and In Vivo Myelination [PDF]
To understand the cellular and in vivo functions of specific K^+ channels in glia, we have studied mice with a null mutation in the weakly inwardly rectifying K^+ channel subunit Kir4.1.

Altered Expression of Ion Channels in White Matter Lesions of Progressive Multiple Sclerosis: What Do We Know About Their Function? [PDF]
Despite significant advances in our understanding of the pathophysiology of multiple sclerosis (MS), knowledge about contribution of individual ion channels to axonal impairment and remyelination failure in progressive MS remains incomplete.

Functional interaction between aquaporins and Kir4.1/Kir4.1‐Kir5.1 channels
In the CNS glial cells, Kir4.1 and Kir4.1‐Kir5.1 channels are involved in clearance of K + during neuronal activity. A number of studies have shown that Kir channels are co‐localized with aquaporins (AQP4) in the glial cells, and coupled water and K ...
