The pharmacology of voltage-gated sodium channel activators [PDF]

Neuropharmacology, 2017
Toxins and venom components that target voltage-gated sodium (NaV) channels have evolved numerous times due to the importance of this class of ion channels in the normal physiological function of peripheral and central neurons as well as cardiac and skeletal muscle.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Ca2+ entry through NaV channels generates submillisecond axonal Ca2+ signaling

eLife, 2020
Calcium ions (Ca2+) are essential for many cellular signaling mechanisms and enter the cytosol mostly through voltage-gated calcium channels. Here, using high-speed Ca2+ imaging up to 20 kHz in the rat layer five pyramidal neuron axon we found that ...

Inhibition by Pregnenolone Sulphate, a Metabolite of the Neurosteroid Pregnenolone, of Voltage-Gated Sodium Channels Expressed in Xenopus Oocytes

Journal of Pharmacological Sciences, 2012
Neurosteroids are known as allosteric modulators of the ligand-gated ion channel superfamily. Voltage-gated sodium channels (Nav) play an important role in mediating excitotoxic damages. Here we report the effects of neurosteroids on the function of Nav,
