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 ...
Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.
By combining gene engineering, Ca²⁺ imaging, and detailed functional tests, the team shows with high precision that skeletal muscle contraction is mainly DICR-driven. This long-accepted mechanism is ...
