          Myasthenia gravis (MG) is an autoimmune disease, which means the body’s defense mechanism, the immune system, begins to attack the body’s own tissues instead of foreign invaders, such as viruses.  It is a chronic (long-lasting) and rare disease that affects the way muscles respond to signals from nerves, leading to muscle weakness.  In myasthenia gravis, the immune system attacks the Read more…
