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.

The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood ...

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 ...

Researchers at NYU College of Dentistry have uncovered what may be biologically driving oral health issues unique to Down ...

Calcium ions serve as versatile second messengers that underpin a diverse range of cellular processes during embryonic and organ development. In developmental systems, the precise spatiotemporal ...

To acquire an image of calcium signaling, Reto Fiolka, a cell biologist at the University of Texas Southwestern Medical Center, illuminated primary cortical neurons from embryonic rats with three ...

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 ...
