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 ...

A new study shows that prolonging cellular energy in brain cells helps transform fleeting experiences into lasting memories.

Spinal cord injury often triggers a cascade of secondary damage that severely limits functional recovery, largely driven by ...

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 represents a fundamental process in cellular communication, orchestrating diverse physiological responses from muscle contraction to neurotransmission and gene regulation. At the ...

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, ...

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 ...

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 ...

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 ...

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

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 ...
