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 ...

This article and associated images are based on a poster originally authored by Sivakumar, M, Smith, E, Shumate, J, Scampavia, L, Spicer, T, Hernandez, D and Peters, C and presented at ELRIG Drug ...

The field of neurotrauma and epilepsy research has increasingly highlighted the pivotal influence of ion channels in the transition from traumatic brain ...

Researchers from The University of Osaka find that potassium KCNQ2/3 channels, which are important for suppressing brain cell ...

Researchers have discovered a new mechanism for potassium channel inhibitor entry, which could improve the specificity of drugs targeting the channel. Upon binding to calcium ions, BK channels allow ...

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 ...

Voltage-gated potassium (Kv) channels play an important role in modulating the electrical activity of cells, opening in response to changes in membrane voltage and allowing potassium ions to escape.

Underlying every thought, heartbeat and movement are ion channels, busily conducting high-speed streams of ions into cells, like subway trains coursing through tunnels. Ion channels span the cellular ...
