Researchers have confirmed that mammalian BK ion channels regulate themselves using a “ball-and-chain” mechanism. A recent ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function ...

Certain cells, commonly called excitable cells, are unique because of their ability to generate electrical signals. Although several types of excitable cells exist — including neurons, muscle ...

An acetylcholine receptor (green) forms a gated ion channel in the plasma membrane. This receptor is ... to flow into the cell. An excitable cell converts chemical or mechanical signals into ...

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through ... these vesicles contain an ion channel—a protein that opens ...

Together, they measured the first Ach-activated single channel recording across a membrane patch of frog skeletal ... between biology using electricity. Every cell is like a battery and the ion ...

In response, a white blood cell arrives ... Study Establishes 'Ball and Chain' Mechanism Inactivates Key Mammalian Ion Channel Mar. 4, 2025 — A new study has unveiled a precise picture of how an ...

Some bacteria deploy tiny spearguns to retaliate against rival attacks. Researchers at the University of Basel have mimicked attacks by poking bacteria with an ultra-sharp tip. Using this approach ...

The BK ion channel pictured above forms a small pathway in the cell membrane (dark gray) that allows potassium ions (purple) to move in and out of the cell. This channel can stop the flow of ions ...
