The uptake of calcium into and extrusion of calcium from the mitochondrial matrix is a
fundamental biological process that has critical effects on cellular metabolism, signaling …

Mitochondria play important roles in maintaining cellular homeostasis and skeletal muscle
health, and damage to mitochondria can lead to a series of pathophysiological changes …

Adult cardiomyocytes are postmitotic cells that undergo very limited cell division. Thus,
cardiomyocyte death as occurs during myocardial infarction has very detrimental …

In heart failure, alterations of Na+ and Ca2+ handling, energetic deficit, and oxidative stress
in cardiac myocytes are important pathophysiological hallmarks. Mitochondria are central to …

Ca 2+ is a ubiquitous intracellular messenger that controls diverse cellular functions but can
become toxic and cause cell death. Selective control of specific targets depends on …

The versatility of mitochondrial metabolism and its fine adjustments to specific physiological
or pathological conditions regulate fundamental cell pathways, ranging from proliferation to …

Synapses enable neurons to communicate with each other and are therefore a prerequisite
for normal brain function. Presynaptically, this communication requires energy and …

Calcium is used in many cellular processes and is maintained within the cell as free calcium
at low concentrations (approximately 100 nM), compared with extracellular (millimolar) …

Impairments in neuronal intracellular calcium (iCa2+) handling may contribute to
Alzheimer's disease (AD) development. Metabolic dysfunction and progressive neuronal …

Mitochondria take up Ca2+ through the mitochondrial calcium uniporter complex to regulate
energy production, cytosolic Ca2+ signalling and cell death,. In mammals, the uniporter …
