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.

Glutathione accelerates sodium channel inactivation in excised rat axonal membrane patches [PDF]

open access: yes, 1992
The effects of glutathione were studied on the gating behaviour of sodium channels in membrane patches of rat axons. Depolarizing pulses from –120 to –40 mV elicited sodium currents of up to 500 pA, indicating the simultaneous activation of up to 250 ...

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

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

Sodium Current Measurements in HEK293 Cells

open access: yesBio-Protocol, 2013
This protocol is used to measure sodium currents from heterologously transfected cells lines, such as HEK293 cells. Standard whole cell patch clamp technique is used to assess ion channel function. This protocol has been used to study cardiac type Nav1.5

Energetics of discrete selectivity bands and mutation-induced transitions in the calcium-sodium ion channels family [PDF]

open access: yes, 2013
We use Brownian dynamics (BD) simulations to study the ionic conduction and valence selectivity of a generic electrostatic model of a biological ion channel as functions of the fixed charge Qf at its selectivity filter.

Rate-dependent effects of lidocaine on cardiac dynamics: Development and analysis of a low-dimensional drug-channel interaction model.

open access: yesPLoS Computational Biology, 2021
State-dependent sodium channel blockers are often prescribed to treat cardiac arrhythmias, but many sodium channel blockers are known to have pro-arrhythmic side effects.

Modeled channel distributions explain extracellular recordings from cultured neurons sealed to microelectrodes [PDF]

open access: yes, 2002
Amplitudes and shapes of extracellular recordings from single neurons cultured on a substrate embedded microelectrode depend not only on the volume conducting properties of the neuron-electrode interface, but might also depend on the distribution of ...

SUMOylation of NaV1.2 channels mediates the early response to acute hypoxia in central neurons. [PDF]

open access: yes, 2016
The mechanism for the earliest response of central neurons to hypoxia-an increase in voltage-gated sodium current (INa)-has been unknown. Here, we show that hypoxia activates the Small Ubiquitin-like Modifier (SUMO) pathway in rat cerebellar granule ...
