Influence of barium on rectification in rat neocortical neurons [PDF]

, 1993
The effect of low concentrations of barium on the membrane properties of rat neocortical neurons was studied in vitro. Potassium currents were examined using single-electrode current- and voltage-clamp techniques. Neurons responded to bath application of

Inwardly Rectifying Potassium Channels: Their Molecular Heterogeneity and Function.

The Japanese Journal of Physiology, 1997
A variety of cells including cardiac myocytes and neuronal cells possess inwardly rectifying K+ (Kir) channels through which currents flow more readily in the inward direction than outward. These K+ channels play pivotal roles in maintenance of the resting membrane potential, in regulation of the action potential duration, in receptor-dependent ...

Multiple PIP₂ binding sites in Kir2.1 inwardly rectifying potassium channels [PDF]

FEBS Letters, 2001
Inwardly rectifying potassium channels require binding of phosphatidylinositol‐4,5‐bisphosphate (PIP2) for channel activity. Three independent sites (aa 175–206, aa 207–246, aa 324–365) were located in the C‐terminal domain of Kir2.1 channels by assaying the binding of overlapping fragments to PIP2 containing liposomes.

Across species: A comparative perspective on red cell homeostasis and its influence on our understanding of human physiology and disease

British Journal of Haematology, EarlyView.
This review highlights how studies on animal red cells have enriched our understanding of the behaviour of those from humans. A comparative perspective has enhanced our knowledge of human red cell pathophysiology Summary This review emphasises how studies on animal red cells have enriched our understanding of the behaviour of those from humans.

Inhibition of Inwardly Rectifying Potassium (Kir) 4.1 Channels Facilitates Brain-Derived Neurotrophic Factor (BDNF) Expression in Astrocytes

Frontiers in Molecular Neuroscience, 2017
Inwardly rectifying potassium (Kir) 4.1 channels in astrocytes regulate neuronal excitability by mediating spatial potassium buffering. Although dysfunction of astrocytic Kir4.1 channels is implicated in the development of epileptic seizures, the ...

Feedback control of excitability and high K+ induced epileptiform bursts in male rat hippocampal slices with a photocaged adenosine A1 receptor agonist

British Journal of Pharmacology, EarlyView.
Background and Purpose Adenosine is a potent regulator of neurotransmission and neuronal excitability, through activation of Gi coupled adenosine A1 receptors (A1Rs). Adenosine has gained interest as an anticonvulsant because of its endogenous involvement in ending seizure activity, but peripheral side effects require local application.

Amyloid-β induces synaptic dysfunction through G protein-gated inwardly rectifying potassium channels in the fimbria-CA3 hippocampal synapse

Frontiers in Cellular Neuroscience, 2013
Last evidences suggest that, in Alzheimer's disease (AD) early stage, Amyloid-β (Aβ) peptide induces an imbalance between excitatory and inhibitory neurotransmission systems resulting in the functional impairment of neural networks.

Genetic risk factor identification for common epilepsies guided by integrative omics data analysis

Epilepsia, EarlyView.
Abstract Objective Genetic generalized epilepsies (GGEs) comprise the most common genetically determined epilepsy syndromes, following a complex mode of inheritance. Although many important common and rare genetic factors causing or contributing to these epilepsies have been identified in the past decades, many features of the genetic architecture are ...

Kir3 channel signaling complexes: Focus on opioid receptor signaling

Frontiers in Cellular Neuroscience, 2014
Opioids are among the most effective drugs to treat severe pain. They produce their analgesic actions by specifically activating opioid receptors located along the pain perception pathway where they inhibit the flow of nociceptive information.

Genetics update: monogenetics, polygene disorders and the quest for modifying genes [PDF]

, 2018
The genetic channelopathies are a broad collection of diseases. Many ion channel genes demonstrate wide phenotypic pleiotropy, but nonetheless concerted efforts have been made to characterise genotype-phenotype relationships.
