Can the Thermodynamic Hodgkin-Huxley Model of Voltage-Dependent Conductance Extrapolate for Temperature? [PDF]

open access: yes, 2014
Hodgkin and Huxley (H-H) fitted their model of voltage-dependent conductances to experimental data using empirical functions of voltage. The thermodynamic H-H model of voltage dependent conductances is more physically plausible, as it constrains and ...

Activity of Palythoa caribaeorum Venom on Voltage-Gated Ion Channels in Mammalian Superior Cervical Ganglion Neurons

open access: yesToxins, 2016
The Zoanthids are an order of cnidarians whose venoms and toxins have been poorly studied. Palythoa caribaeorum is a zoanthid commonly found around the Mexican coastline. In this study, we tested the activity of P.

Cellular hyper-excitability caused by mutations that alter the activation process of voltage-gated sodium channels

open access: yesFrontiers in Physiology, 2015
Voltage-gated sodium channels (Nav) are widely expressed as macro-molecular complexes in both excitable and non-excitable tissues. In excitable tissues, the upstroke of the action potential is the result of the passage of a large and rapid influx of ...

Sodium channel inactivation kinetics of rat sensory and motor nerve fibres and their modulation by glutathione [PDF]

open access: yes, 1993
Na+ channel currents of rat motor and sensory nerve fibres were studied with the patch-clamp technique on enzymatically demyelinated axons. Differences between motor and sensory fibres in multi-channel inactivation kinetics and the gating of late single ...

Mutations in the voltage-gated sodium channel gene associated with deltamethrin resistance in commercially sourced Phytoseiulus persimilis [PDF]

open access: yes, 2020
The implementation of Integrated Pest Management (IPM) in current agricultural practice is a convenient and very effective strategy to maintain pest populations under control. The use of Biological Control Agents, like Phytoseiulus persimilis, is key for

Structure-guided unlocking of NaX reveals a non-selective tetrodotoxin-sensitive cation channel

open access: yesNature Communications, 2022
NaX is an atypical member of the voltage-gated sodium channel family that may contribute to Na+ homeostasis. Here, the authors describe the structural and functional attributes of the human NaX channel to reveal new insights into its physiology.

Voltage‐gated Sodium Channels in Epilepsy [PDF]

open access: yesEpilepsia, 2002
Summary: Animal experiments, and particularly functional investigations on human chronically epileptic tissue as well as genetic studies in epilepsy patients and their families strongly suggest that some forms of epilepsy may share a pathogenetic mechanism: an alteration of voltage‐gated sodium channels. This review summarizes recent data on changes of

Structural Advances in Voltage-Gated Sodium Channels

open access: yesFrontiers in Pharmacology, 2022
Voltage-gated sodium (NaV) channels are responsible for the rapid rising-phase of action potentials in excitable cells. Over 1,000 mutations in NaV channels are associated with human diseases including epilepsy, periodic paralysis, arrhythmias and pain disorders.

The actions of chloride channel blockers, barbiturates and a benzodiazepine on Caenorhabditis elegans glutamate- and ivermectin-gated chloride channel subunits expressed in Xenopus oocytes [PDF]

open access: yes, 2009
The pharmacology of Caenorhabditis elegans glutamate-gated chloride (GluCl) channels was determined by making intracellular voltage-clamp recordings from Xenopus oocytes expressing GluCl subunits. As previously reported (Cully et al.

Ion channel clustering at the axon initial segment and node of Ranvier evolved sequentially in early chordates. [PDF]

open access: yesPLoS Genetics, 2008
In many mammalian neurons, dense clusters of ion channels at the axonal initial segment and nodes of Ranvier underlie action potential generation and rapid conduction.
