Ion trapping with fast-response ion-selective microelectrodes enhances detection of extracellular ion channel gradients [PDF]

open access: yes, 2008
Previously, functional mapping of channels has been achieved by measuring the passage of net charge and of specific ions with electrophysiological and intracellular fluorescence imaging techniques.

Photocontrol of Voltage-Gated Ion Channel Activity by Azobenzene Trimethylammonium Bromide in Neonatal Rat Cardiomyocytes. [PDF]

open access: yesPLoS ONE, 2016
The ability of azobenzene trimethylammonium bromide (azoTAB) to sensitize cardiac tissue excitability to light was recently reported. The dark, thermally relaxed trans- isomer of azoTAB suppressed spontaneous activity and excitation propagation speed ...

A Sea Anemone Lebrunia neglecta Venom Fraction Decreases Boar Sperm Cells Capacitation: Possible Involvement of HVA Calcium Channels

open access: yesToxins, 2022
Sea anemones produce venoms characterized by a complex mixture of low molecular weight compounds, proteins and peptides acting on voltage-gated ion channels. Mammal sperm cells, like neurons, are characterized by their ion channels. Calcium channels seem

Kv7 and Kv11 channels in myometrial regulation. [PDF]

open access: yes, 2013
Ion channels play a key role in defining myometrial contractility. Modulation of ion channel populations is proposed to underpin gestational changes in uterine contractility associated with the transition from uterine quiescence to active labour.

Cnidarian Toxins Acting on Voltage-Gated Ion Channels

open access: yesMarine Drugs, 2006
: Voltage-gated ion channels generate electrical activity in excitable cells. As such, they are essential components of neuromuscular and neuronal systems, and are targeted by toxins from a wide variety of phyla, including the cnidarians. Here, we review

Voltage-Gated Potassium Channels as Regulators of Cell Death

open access: yesFrontiers in Cell and Developmental Biology, 2020
Ion channels allow the flux of specific ions across biological membranes, thereby determining ion homeostasis within the cells. Voltage-gated potassium-selective ion channels crucially contribute to the setting of the plasma membrane potential, to volume

The influence of lipids on voltage-gated ion channels [PDF]

open access: yesCurrent Opinion in Structural Biology, 2012
Voltage-gated ion channels are responsible for transmitting electrochemical signals in both excitable and non-excitable cells. Structural studies of voltage-gated potassium and sodium channels by X-ray crystallography have revealed atomic details on their voltage-sensor domains (VSDs) and pore domains, and were put in context of disparate mechanistic ...

Potential roles of voltage-gated ion channel disruption in Tuberous Sclerosis Complex

open access: yesFrontiers in Molecular Neuroscience
Tuberous Sclerosis Complex (TSC) is a lynchpin disorder, as it results in overactive mammalian target of rapamycin (mTOR) signaling, which has been implicated in a multitude of disease states.

Optical electrophysiology for probing function and pharmacology of voltage-gated ion channels

open access: yeseLife, 2016
Voltage-gated ion channels mediate electrical dynamics in excitable tissues and are an important class of drug targets. Channels can gate in sub-millisecond timescales, show complex manifolds of conformational states, and often show state-dependent ...
