The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

Calcium ions orchestrate contraction and relaxation in airway smooth muscle by regulating excitation–contraction coupling. In quiescent cells, basal cytosolic Ca2+ is maintained at nanomolar levels by ...

Researchers have developed a novel method for simultaneously recording action potentials (APs)—temporary changes in electrical potential when cells become excited—and calcium transients—calcium ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...
