Myasthenia gravis (MG) is the archetype of B-cell–mediated autoimmune disorders. The pathology of MG sets it apart from the bulk of autoimmune diseases because it is caused by autoantibodies with clear pathogenic effects. Symptoms range from a purely ocular form to weakness of the limb, bulbar and respiratory muscles, which are attributed to the unique pathophysiology of impaired neuromuscular transmission, which produces a dynamic disorder governed by the cycle of neuromuscular junction (NMJ) repair.
