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 ...

In the budding yeast Saccharomyces cerevisiae, intracellular calcium acts as a versatile second messenger coordinating stress responses, ion balance and cell wall integrity. Under resting conditions, ...

Think calcium only matters for bone health? These overlooked signs could indicate your body needs more of this nutrient.

Carbon monoxide (CO) is a colorless, odorless, tasteless gas which, at high levels, is poisonous. It is formed during the incomplete combustion of fossil fuels and wood. Despite improvements in ...

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in memory. CaMKII alters the plasma membrane's biochemical properties, ...
