Mitochondrial calcium signaling is crucial for energy metabolism and calcium homeostasis, but monitoring it accurately is challenging due to pH fluctuations. Existing GECIs are often sensitive to pH ...

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 ...

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 ...

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 ...

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 ...

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 ...

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

The cell's endoplasmic reticulum (ER) plays a central role in protein synthesis, folding, and calcium (Ca²⁺) storage. When ...

Emerging research suggests milk fever may be less about calcium deficiency and more about how inflammation and metabolism ...
