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 ...

Researchers from the University of Utah have identified calcium as a key chemical signal that triggers microglia during ...

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 had previously discovered a population of immune cells within the brain that can act as accelerators and brakes for anxiety in mice. Now, new research from the lab of Mario Capecchi, Ph.D.

The single-celled Stentor coeruleus learns through CaMKII-driven protein modification, mirroring mechanisms found in the human brain.

When the electrical signal reaches the end of one nerve cell it is converted into a biochemical signal, in the form of calcium. In turn, an increase in calcium triggers the release of signalling ...

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 ...
