Scientists have made a significant advance in understanding how potassium channels, which permit the flow of electric currents central to many of the body's biological processes, control the flow of ...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes various symptoms that go beyond respiratory problems. Neurological, cardiac, and other issues can emerge during infection and after ...

Potassium channels are essential membrane proteins that enable the selective and rapid transport of K⁺ ions, a process fundamental to cellular excitability and signal transduction. Recent research has ...

Biohaven didn't receive the clinical readout it was hoping for over the festive period. | As the biopharma wound down for the ...

Potassium channels are openings that allow charged potassium atoms to cross the cell membrane. Voltage-gated potassium channels — which open only when a specific voltage is reached across the cell ...

Previous studies report that mice lacking BACE1 have seizures, but disagree about why. Now, German scientists led by Christian Alzheimer and Tobias Huth of Friedrich-Alexander-Universität ...

Potassium channels are critical structures in biology; they selectively allow potassium ions to pass through the membrane surrounding cells. The precise gating of that channel is essential to its ...

Ion selectivity is an important property of cell membrane ion channels. For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready ...

Defying one of biology’s more persistent dogmas, a potassium channel combines functions once thought to be invariably asunder. This channel, which is found in common bacteria, incorporates a subunit ...

For decades it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers have now elucidated the transport path ...

Following this design principle, the researchers create angstrom-scale pores in bi-layer graphene sheets, and decorate the two pore edges with twisted rings of carbonyl groups. The artificial ion ...
