Voltage-gated sodium channels are expressed across excitable cells where they are crucial for sharp initiation dynamics and propagation of the action potential1. TheSCN5Agene encodes for the cardiac sodium channel α-subunit, Nav1.5.SCN5Amutations have been linked to cardiac arrhythmias such as Brugad...
voltage-gated sodium channel 1.7analgesicslappaconitinetetracainebupivacaineLappaconitine (LA) has been widely used for postoperative and cancer pain control. LA exhibits excellent analgesic activity with a longer effective time than common local anesthetics such as tetracaine and bupivacaine. However, the ...

Any change in the potential across the membrane (due to a propagating impulse or an experimentalist's stimulus) is sensed by the voltage-gated sodium channels carrying an inward sodium current, thus triggering a rapid sodium influx into the cardiomyocytes. This produces the typical rapid upstroke ...

Hodgkin-Huxley parameters were used to mimic the presence of voltage-gated sodium (NaV) channels in HEK-293 cells. Recombinant expression of either TREK-1 or TASK-3 channels was then used to generate a hyperpolarised resting membrane potential (RMP) leading to the characteristic non-linear ...
This strategy might be used for the large scale screening for target-specific interacting peptides of VGSCs or other ion channels. A mong various types of ion channels, voltage-gated sodium channels (VGSCs) are responsible for the genesis and propagation of action potential, by which the ...
