Myasthenia gravis is an autoimmune disease, meaning the body's immune system attacks its own healthy tissues. In this case, the immune system attacks the receptors on the muscle cells that respond to acetylcholine, a neurotransmitter that controls muscle contraction. This leads to muscle weakness and fatigue.
