Pathophysiology of skeletal muscle disturbances in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS).
Wirth, Klaus J, Scheibenbogen, Carmen·Journal of translational medicine·2021
This study proposes that ME/CFS may be caused by a problem with how the body's nervous system controls blood vessels and muscle function. The researchers suggest that faulty beta-2 receptors (proteins that normally help regulate these systems) lead to poor blood flow in muscles, buildup of harmful substances, and damage to the energy-producing structures inside muscle cells. This creates a harmful cycle where even small amounts of activity can trigger the same problems again and again, explaining why patients experience crashes after exertion.
