Is Myasthenia Gravis An Autoimmune Disease?

Q:
Is myasthenia gravis an autoimmune disease?

A:
Myasthenia gravis is an autoimmune disease. The immune system is supposed to protect you from foreign organisms, but in myasthenia gravis, it mistakenly attacks itself.

In myasthenia gravis, antibodies block the receptors for acetylcholine at the neuromuscular junction so as to prevent the muscle from contracting. Mostly, it is caused by antibodies to the acetylcholine receptor itself.

Besides, antibodies to other proteins, such as MuSK protein, can also lead to failed transmission at the neuromuscular junction.

These antibodies are produced by the body’s own immune system.

Moreover, people with myasthenia gravis may be more likely to have autoimmune conditions, including rheumatoid arthritis and lupus.
