Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal 'firing' in the central nervous system and for brain and heart function. These channels use a ' ...

Maintenance of cardiac rhythm and pain sensation require the flow of ions across the membranes of all cells. Ion channels, which facilitate this movement, are protein assemblies that penetrate the ...

They are literally channels for communication: Pore-forming proteins in living cells, termed ion channels, are embedded in the outer membrane of almost all cell types and play a crucial role in the ...

Ion channels enable passive ion flow towards equilibrium, which is driven by ion concentration differences across the membrane and the membrane potential (the difference electric potential between the ...

Cells send electrical impulses throughout the body, but electrophysiologists struggled to tune into these signals until the patch clamp technique was developed. Although biophysicist Bernard Katz from ...

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the ...

Researchers have discovered how an ion channel in the brain's neurons has a kind of 'molecular memory', which contributes to the formation and preservation of lifelong memories. The researchers have ...

Researchers decipher the function of an ion channel involved in cellular degradation processes and create new possibilities for Parkinson’s therapies. Washbowls, bathtubs, and sinks are all fitted ...
