New research identifies calcium as a key chemical signal within brain immune cells that regulates anxiety-related behaviors ...

Researchers had previously discovered a population of immune cells within the brain that can act as accelerators and brakes ...

Mitochondrial calcium signalling plays a fundamental role in cellular homeostasis by modulating energy production and activating key metabolic enzymes. Calcium ions (Ca2+) are dynamically exchanged ...

High calcium levels in brain microglia are linked to anxiety, suggesting new treatment possibilities for neuropsychiatric disorders. Research from the University of Utah highlights calcium as a key ...

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

In a sharp and pointy world, wound healing is a critical and marvelous process. Despite a tremendous amount of scientific study, many outstanding mysteries still surround the way in which cells in ...

Calcium signalling is a pivotal regulatory mechanism in ciliated protozoa, orchestrating a myriad of cellular processes from ciliary beating to membrane trafficking. Recent studies have illuminated ...

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

Background: Wnt signaling affects fundamental development pathways by regulating cell proliferation and differentiation. Aberrant activation of Wnt/ß-catenin signaling promotes the development of ...

A new method exposes key details of the mechanism behind calcium signaling in prokaryotes for the first time. Working in a Listeria monocytogenes model, researchers from Umeå University (Sweden) led ...

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 ...
