Structure and function of voltage-gated sodium channels.
1. Sodium channels mediate fast depolarization and conduct electrical impulses throughout nerve, muscle and heart. This paper reviews the links between sodium channel structure and function. 2. Sodium channels have a modular architecture, with distinct regions for the pore and the gates. The separation is far from absolute, however, with extensive interaction among the various parts of the chan...
متن کاملVoltage-Gated Sodium Channels Modulation by Bothutous Schach Scorpion Venom
Buthotus schach is one of the dangers scorpion in Iran that belong to the Buthidae family. Toxins are existing in venom scorpion, modulate the ion channels by blocking or opening the pore of the channel or by altering the voltage gating and useful as pharmacological tools. In the present study, we investigated the effect of venom and its obtained fractions by gel filtrations on electrophysiolog...
متن کاملVOLTAGE-GATED ION CHANNELS Voltage-Gated Sodium Channels
Antiepileptic drugs (AEDs) protect against seizures through interactions with a variety of cellular targets. By affecting the functional activity of these targets, AEDs suppress abnormal hypersynchronous activity in brain circuits, leading to protection against seizures. The actions on these targets can be categorized into four broad groups: (i) modulation of voltage-gated ion channels, includi...
متن کاملVoltage-gated sodium channels and hyperalgesia.
Physiological and pharmacological evidence both have demonstrated a critical role for voltage-gated sodium channels (VGSCs) in many types of chronic pain syndromes because these channels play a fundamental role in the excitability of neurons in the central and peripheral nervous systems. Alterations in function of these channels appear to be intimately linked to hyperexcitability of neurons. Ma...
متن کاملNoncanonical Roles of Voltage-Gated Sodium Channels
The Hodgkin-Huxley formulation, at its 60th anniversary, remains a bastion of neuroscience. Sodium channels Nav1.1-Nav1.3 and Nav1.6-Nav1.9 support electrogenesis in neurons and are often considered "neuronal," whereas Nav1.4 and Nav1.5 drive electrogenesis in skeletal and cardiac muscle. These channels are, however, expressed in cell types that are not considered electrically excitable. Here, ...
