Current Challenges of Mitochondrial Potassium Channel Research

open access: yesFrontiers in Physiology, 2022
In this paper, the current challenges of mitochondrial potassium channels research were critically reviewed. Even though recent progress in understanding K+ traffic in mitochondria has been substantial, some basic issues of this process remain unresolved.

Involvement of Potassium Channel Signalling in Migraine Pathophysiology

open access: yesPharmaceuticals, 2023
Migraine is a primary headache disorder ranked as the leading cause of years lived with disability among individuals younger than 50 years. The aetiology of migraine is complex and might involve several molecules of different signalling pathways ...

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.

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 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 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 ...
