Latest Sodium channel Stories
Using spider toxins to study the proteins that let nerve cells send out electrical signals, Johns Hopkins researchers say they have stumbled upon a biological tactic that may offer a new way to protect crops from insect plagues in a safe and environmentally responsible way.
Researchers at Johns Hopkins have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they say.
Take a muscle cell, modify it over millions of years, and you end up with an exciting and literally shocking evolutionary result: the electric fish.
Scientists have figured out how calcium channels – the infinitesimal cell membrane pores that generate electrical signals by gating a charged-particle influx – have solved a "needle in a haystack" problem.
The painful, potentially deadly stings of bark scorpions are nothing more than a slight nuisance to grasshopper mice, which voraciously kill and consume their prey with ease.
That flutter in your heart may have more to do with the movement of sodium ions than the glance of a certain someone across a crowded room.
Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch have found out why the African naked mole-rat (Heterocephalus glaber), one of the world’s most unusual mammals, feels no pain when exposed to acid.
Drawing on X-ray crystallography and experimental data, as well as a software suite for predicting and designing protein structures, a UC Davis School of Medicine researcher has developed an algorithm that predicts what has been impossible to generate in the laboratory: the conformational changes in voltage-gated sodium channels when they are at rest or actively transmitting a signal in muscle and nerve cells.
Researchers at the University of California, Riverside have made a discovery in the lab that could help drug manufacturers develop new antiepileptic drugs and explore novel strategies for treating seizures associated with epilepsy â€“ a disease affecting about two million Americans.
An essential component of animal nervous systemsâ€”sodium channelsâ€”evolved prior to the evolution of those systems.
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
