Antillatoxin is a sodium channel activator that displays unique efficacy in heterologously expressed rNav1.2, rNav1.4 and rNav1.5 alpha subunits

open access: yesBMC Neuroscience, 2010
Background Antillatoxin (ATX) is a structurally unique lipopeptide produced by the marine cyanobacterium Lyngbya majuscula. ATX activates voltage-gated sodium channel α-subunits at an undefined recognition site and stimulates sodium influx in neurons ...

A model of sodium channels

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2005
We have explored the permeation and blockage of ions in sodium channels, relating the channel structure to function using electrostatic profiles and Brownian dynamics simulations. The model used resembles the KcsA potassium channel with an added external vestibule and a shorter selectivity filter.

Recent developments regarding voltage-gated sodium channel blockers for the treatment of inherited and acquired neuropathic pain syndromes

open access: yesFrontiers in Pharmacology, 2011
Chronic and neuropathic pain constitute significant health problems affecting millions of individuals each year. Pain sensations typically originate in sensory neurons of the peripheral nervous system (PNS) which relay information to the central nervous

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.

Cannabidiol interactions with voltage-gated sodium channels

open access: yeseLife, 2020
Voltage-gated sodium channels are targets for a range of pharmaceutical drugs developed for the treatment of neurological diseases. Cannabidiol (CBD), the non-psychoactive compound isolated from cannabis plants, was recently approved for treatment of two

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 ...

Electrocardiographic Biomarkers for Detection of Drug-Induced Late Sodium Current Block. [PDF]

open access: yesPLoS ONE, 2016
Drugs that prolong the heart rate corrected QT interval (QTc) on the electrocardiogram (ECG) by blocking the hERG potassium channel and also block inward currents (late sodium or L-type calcium) are not associated with torsade de pointes (e.g. ranolazine

Role of the C-terminal domain in the structure and function of tetrameric sodium channels [PDF]

open access: yes, 2013
Voltage-gated sodium channels have essential roles in electrical signalling. Prokaryotic sodium channels are tetramers consisting of transmembrane (TM) voltage-sensing and pore domains, and a cytoplasmic carboxy-terminal domain.

Pumilio binds para mRNA and requires nanos and brat to regulate sodium current in drosophila motoneurons [PDF]

open access: yes, 2008
Homeostatic regulation of ionic currents is of paramount importance during periods of synaptic growth or remodeling. Our previous work has identified the translational repressor Pumilio (Pum) as a regulator of sodium current (INa) and excitability in ...

Regulation of neuronal excitability through pumilio-dependent control of a sodium channel gene [PDF]

open access: yes, 2004
Dynamic changes in synaptic connectivity and strength, which occur during both embryonic development and learning, have the tendency to destabilize neural circuits.
