A joint study by the University Medical Center Göttingen (UMG) and the University Hospital Würzburg provides new insights into why heart muscle cells lose their rhythm in atrial fibrillation.

Northwestern Medicine scientists have discovered how calcium signaling channels in microglia—the primary immune cells of the brain—regulate neuroinflammation and promote the development of behaviors ...

Calcium (Ca 2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum (ER), a cellular organelle that synthesizes and transports proteins, is ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

Scientists have addressed a long-standing controversy behind the molecular players mediating calcium signaling, a biological process that coordinates a wide array of physiological responses, according ...

Calcium is widely known for its role in maintaining strong bones and teeth, but it is also one of the body's most important cellular messengers. Calcium signals help regulate muscle contraction, ...

A new method exposes key details of the mechanism behind calcium signaling in prokaryotes for the first time. Working in a Listeria monocytogenes model, researchers from Umeå University (Sweden) led ...

Mitochondria play a crucial role in maintaining energy balance and cellular health. Recent studies have shown that chronic stress in neuronal mitochondria can have far-reaching effects, not only ...

Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...

Summary: Researchers compiled emerging evidence to prove that astrocytes, traditionally dismissed as passive, structural ...
