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 ...

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 ...

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

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 ...

Azetukalner, a Kv7 potassium channel opener, reduced the frequency of focal onset seizures by a placebo-adjusted rate of 42.7 ...

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.

Potassium KCNQ2/3 channels are crucial for suppressing the excitability of brain cells, or neurons. When these channels don't ...

Researchers find blocking the KCNB2 gene can slow tumor growth, paving the way for next-gen treatments for childhood brain cancer. Scientists at The Hospital for Sick Children (SickKids) have ...

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 ...
