A key approach to understanding the brain is to observe the behavioral effects of turning on specific populations of neurons. One of the most popular approaches to controlling neuronal activity in ...

Kv7.2/7.3 channels are voltage-gated potassium channels involved in regulating membrane potential and neuronal excitability.

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 ...

Potassium (K +) channels are small, highly specialized conduits within every living cell that are responsible for the extremely selective and rapid transport of K + ions across cell membranes. Voltage ...

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 ...

(Nanowerk Spotlight) Biological potassium channels are marvels of selective permeability, allowing rapid transport of potassium ions (ionic radius of 1.3 Å) while blocking the smaller sodium ions (1.0 ...

Intrigued by the properties of ion channel proteins commonly observed in cells, researchers have developed the first synthetic mechanosensitive potassium channel using a newly developed aromatic ...

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 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 ...

A study conducted by researchers at the Center for Redox Processes in Biomedicine (Redoxoma) has shown that ATP-sensitive mitochondrial potassium channels (MitoK ATP) are involved in both the ...
