Unraveling a key junction underlying muscle contraction Date: July 31, 2024 Source: University of California - San Diego Summary: Using powerful new visualization technologies, researchers have ...

All skeletal muscle contractions originate at the junction between motor neurons, which originate in the spinal cord and brainstem, and muscle fibers. It's here that neurons release a transmitter ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

Importantly, the study revealed that non-VDCC channels—particularly a protein called Orai1 that forms SOCCs—are the main drivers of PAF-induced muscle contraction in the esophagus.

The discovery that some muscle proteins act as a temperature sensor may lead to a new hyperthermia strategy, in which skeletal muscle performance is improved by warming up the muscle.

Real-time imaging of sub-cellular reactive oxygen species, Ca2+ signaling, and excitation-contraction coupling in skeletal muscle under physiological and pathophysiological conditions. The research in ...
