Drunk potassium channels [PDF]

open access: yesEuropace, 2011
We report the case of a 42-year-old woman who was admitted due to alcohol induced dehydration leading to cardiac symptoms. On physical examination severe hypokalaemia and long QT syndrome were apparent. During potassium (K+) supplementation we simultaneously observed QT interval recovery.

The role of axonal voltage-gated potassium channels in tDCS

open access: yesBrain Stimulation, 2022
Background: Transcranial direct current stimulation (tDCS) is a non-invasive sub-threshold stimulation, widely accepted for its amelioration of distinct neuropsychiatric disorders.

Potassium Channels in Epilepsy [PDF]

open access: yesCold Spring Harbor Perspectives in Medicine, 2016
This review attempts to give a concise and up-to-date overview on the role of potassium channels in epilepsies. Their role can be defined from a genetic perspective, focusing on variants and de novo mutations identified in genetic studies or animal models with targeted, specific mutations in genes coding for a member of the large potassium channel ...

Potassium channels [PDF]

open access: yesFEBS Letters, 2003
The atomic structures of K+ channels have added a new dimension to our understanding of K+ channel function. I will briefly review how structures have influenced our views on ion conduction, gating of the pore, and voltage sensing.

The neuroglial potassium cycle during neurotransmission: role of Kir4.1 channels. [PDF]

open access: yesPLoS Computational Biology, 2015
Neuronal excitability relies on inward sodium and outward potassium fluxes during action potentials. To prevent neuronal hyperexcitability, potassium ions have to be taken up quickly.

Potassium Ion Channels in Glioma: From Basic Knowledge into Therapeutic Applications

open access: yesMembranes, 2023
Ion channels, specifically those controlling the flux of potassium across cell membranes, have recently been shown to exhibit an important role in the pathophysiology of glioma, the most common primary central nervous system tumor with a poor prognosis ...

Structure of potassium channels [PDF]

open access: yesCellular and Molecular Life Sciences, 2015
Potassium channels ubiquitously exist in nearly all kingdoms of life and perform diverse but important functions. Since the first atomic structure of a prokaryotic potassium channel (KcsA, a channel from Streptomyces lividans) was determined, tremendous progress has been made in understanding the mechanism of potassium channels and channels conducting ...

The Natural Flavone Acacetin Blocks Small Conductance Ca2+-Activated K+ Channels Stably Expressed in HEK 293 Cells

open access: yesFrontiers in Pharmacology, 2017
The natural flavone acacetin inhibits several voltage-gated potassium currents in atrial myocytes, and has anti-atrial fibrillation (AF) effect in experimental AF models.

Role of Kv1 potassium channels in regulating dopamine release and presynaptic D2 receptor function. [PDF]

open access: yesPLoS ONE, 2011
Dopamine (DA) release in the CNS is critical for motor control and motivated behaviors. Dysfunction of its regulation is thought to be implicated in drug abuse and in diseases such as schizophrenia and Parkinson's.

Distinct Distribution Patterns of Potassium Channel Sub-Units in Somato-Dendritic Compartments of Neurons of the Medial Superior Olive

open access: yesFrontiers in Cellular Neuroscience, 2019
Coincidence detector neurons of the medial superior olive (MSO) are sensitive to interaural time differences in the range of a few tens of microseconds. The biophysical basis for this remarkable acuity is a short integration time constant of the membrane,
