The A-current: how ubiquitous a feature of excitable cells is it?

diversity

Rogawski MA.
GSID: TRQSOe9hZ40J
MA Rogawski - Trends in Neurosciences, 1985 - Elsevier

The membranes of most excitable cells contain a distinct set of potassium channels that rapidly open and close following depolarization, giving rise to a transient outward …

Complementary and synergistic therapeutic effects of compounds found in Kampo medicine: analysis of daikenchuto.

Frontiers in pharmacology

Kono T, Shimada M, Yamamoto M, Kaneko A, Oomiya Y, Kubota K, Kase Y, Lee K, Uezono Y.

Front Pharmacol. 2015 Aug 04;6:159. doi: 10.3389/fphar.2015.00159. eCollection 2015.

Herbal medicines have been used in Japan for more than 1500 years and traditional Japanese medicines (Kampo medicines) are now fully integrated into the modern healthcare system. In total, 148 Kampo formulae are officially approved as prescription drugs and...

The neurotoxic effects of hydrogen peroxide and copper in Retzius nerve cells of the leech Haemopis sanguisuga.

Biology open

Jovanovic ZD, Stanojevic MB, Nedeljkov VB.
PMID: 26935393
Biol Open. 2016 Apr 15;5(4):381-8. doi: 10.1242/bio.014936.

Oxidative stress and the generation of reactive oxygen species (ROS) play an important role in cellular damage. Electrophysiological analyses have shown that membrane transport proteins are susceptible to ROS. In the present study, oxidative stress was induced in Retzius...

The Impact of BK Channels on Cellular Excitability Depends on their Subcellular Location.

Frontiers in cellular neuroscience

Bock T, Stuart GJ.
PMID: 27630543
Front Cell Neurosci. 2016 Aug 31;10:206. doi: 10.3389/fncel.2016.00206. eCollection 2016.

Large conductance calcium-activated potassium channels (or BK channels) fulfil a multitude of roles in the central nervous system. At the soma of many neuronal cell types they control the speed of action potential (AP) repolarization and therefore they can...

Molecular dynamics simulations of membrane proteins.

Biophysical reviews

Baştuğ T, Kuyucak S.
PMID: 28510077
Biophys Rev. 2012 Sep;4(3):271-282. doi: 10.1007/s12551-012-0084-9. Epub 2012 Sep 01.

Membrane proteins control the traffic across cell membranes and thereby play an essential role in cell function from transport of various solutes to immune response via molecular recognition. Because it is very difficult to determine the structures of membrane...

Gain-of-function defects of astrocytic Kir4.1 channels in children with autism spectrum disorders and epilepsy.

Scientific reports

Sicca F, Ambrosini E, Marchese M, Sforna L, Servettini I, Valvo G, Brignone MS, Lanciotti A, Moro F, Grottesi A, Catacuzzeno L, Baldini S, Hasan S, D'Adamo MC, Franciolini F, Molinari P, Santorelli FM, Pessia M.
PMID: 27677466
Sci Rep. 2016 Sep 28;6:34325. doi: 10.1038/srep34325.

Dysfunction of the inwardly-rectifying potassium channels Kir4.1 (KCNJ10) represents a pathogenic mechanism contributing to Autism-Epilepsy comorbidity. To define the role of Kir4.1 variants in the disorder, we sequenced KCNJ10 in a sample of affected individuals, and performed genotype-phenotype correlations....

KCl Mediates K(+) Channel-Activated Mitogen-Activated Protein Kinases Signaling in Wound Healing.

Archives of plastic surgery

Shim JH, Lim JW, Kim BK, Park SJ, Kim SW, Choi TH.
PMID: 25606484
Arch Plast Surg. 2015 Jan;42(1):11-9. doi: 10.5999/aps.2015.42.1.11. Epub 2015 Jan 14.

BACKGROUND: Wound healing is an interaction of a complex signaling cascade of cellular events, including inflammation, proliferation, and maturation. K(+) channels modulate the mitogen-activated protein kinase (MAPK) signaling pathway. Here, we investigated whether K(+) channel-activated MAPK signaling directs collagen...

Autoimmune encephalopathy and drug refractory seizures with the presence of two autoantibodies specific for the neuronal cell surface.

Front Cell Neurosci. 2014 Jun 17;8:164. doi: 10.3389/fncel.2014.00164. eCollection 2014.

Synaptic communication requires constant adjustments of pre- and postsynaptic efficacies. In addition to synaptic long term plasticity, the presynaptic machinery underlies homeostatic regulations which prevent out of range transmitter release. In this minireview we will discuss the relevance of...
