Mechanisms of (local) anaesthetics on voltage-gated sodium and other ion channels.
Local anaesthetics have been used clinically for well over a century, but the molecular mechanisms by which they alter speci®c functions of the peripheral nerve system remained unclear for a long time. Investigations during the last few decades presented evidence implicating the sodium (Na) channel protein as a target for speci®c, clinically important, local anaesthetic effects on mammalian neu...
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 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...

differentiated newt cells, but not in their mammalian counterparts. There has been some progress along these lines but not at the level of pinpointing the genetic differences. It is important to remember that there are examples, such as the axolotl lens, where a particular tissue does not regenerate even though the animal is capable of regenerating other structures. Such a context may be more f...
متن کاملMechanism of Ion Permeation in Mammalian Voltage-Gated Sodium Channels
Recent determination of the crystal structures of bacterial voltage-gated sodium (NaV) channels have raised hopes that modeling of the mammalian counterparts could soon be achieved. However, there are substantial differences between the pore domains of the bacterial and mammalian NaV channels, which necessitates careful validation of mammalian homology models constructed from the bacterial NaV ...
