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 ...

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 ...

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 ...

The Importance of Gliotransmitters for Brain Function, Plus Cognitive and Motor Efficiencies Gliotransmitters are neurochemicals released by glial cells. They support communication between neurons and ...

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 ...

While calcium is most often thought of in the context of building strong bones and teeth, its role in the body extends far ...
