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.

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 ...

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 ...

Instead of blocking the calcium channel completely, which is a less refined method, future drugs can be designed to fine-tune calcium channel activity in pain signalling," says Antonios Pantazis. It ...

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 ...
