In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

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 ...

“This article illuminates the biology behind EDG-5506, demonstrating that modulation of fast skeletal muscle contraction protects against muscle injury, degeneration and fibrosis in models of DMD,” ...

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.

Skeletal muscle is the type of muscle that controls movement. Problems with these muscles can be minor, life-threatening, or ongoing problems that make it hard to perform basic daily activities.

From arthritis and heart failure to diabetes and menopause, many conditions are associated with muscle weakness and increased fat deposits. Now a multidisciplinary team of researchers at the ...

Background: Delayed onset muscle soreness (DOMS) occurs after unaccustomed exercise and has been suggested to be attributable to reactive oxygen species (ROS). Previous studies have shown increased ...

Scientists have established a link between gut microbes and muscle growth and function -- a finding that could open new doors to interventions for age-related skeletal muscle loss. The microorganisms ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...
