Fig. 1 The organization of voltage-gated sodium channels. Voltage-gated Na+Channel Inhibitor Brevetoxins derivatives (PbTx-1 to PbTx-10) are potent lipid-soluble polyether neurotoxins produced by the marine dinoflagellate Karina brevis. Two skeletal types are known, and each type has a number of...
Voltage-gated sodium channels (VGSCs) are transmembrane proteins that increase the permeability of sodium ions across membranes. The permeability of these channels depends on the voltage drop across the membrane. In a typical neuronal action potential, VGSCs remain closed until the membrane potential ...
Sodium ChannelsSignal TransductionIon Channel GatingVoltage-gated sodium channels subserve regenerative excitation throughout the nervous system, as well as in skeletal and cardiac muscle. This excitation results from a voltage-dependent mechanism that increases regeneratively and selectively the sodium ...
Voltage-gated sodium channels are proteins found in mammalian neurons that are responsible for generating electrical signals known as action potentials. When the membrane of a neuron becomes depolarized, these channels briefly open, allowing sodium ions to enter the cell. Sodium channels are composed ...
The basis of epilepsy is an increase in neuronal excitability that, in some cases, may be caused by functional defects in neuronal voltage gated sodium channels, Nav1.1 and Nav1.2. The effects of antiepileptic drugs (AEDs) as effective therapies for epilepsy have been characterized by extensive ...
Voltage-gated sodium channels subserve regenerative excitation throughout the nervous system, as well as in skeletal and cardiac muscle. This excitation results from a voltage-dependent mechanism that increases regeneratively and selectively the sodium conductance of the channel e-fold for a 4–7 mV...
These structures, along with those from other channels, give unprecedented insight into the structural basis of sodium channel function. This volume of the Handbook of Experimental Pharmacology will explore sodium channels from the perspectives of their biophysical behavior, their structure, the drugs ...
Voltage-gated sodium channels (VGSCs) initiate action potentials in electrically excitable cells and tissues. Surprisingly, some VGSC genes are aberrantly expressed in a variety of cancers, derived from "non-excitable" tissues that do not generate classic action potentials, showing potential as a prom...
