Definition

Acetylcholine receptor antibody is an antibody found in the blood of people with myasthenia gravis.

The acetylcholine receptor antibody attacks receptors for the neurotransmitter acetylcholine, which sends signals from nerves to muscles and from nerve to nerve in the brain. The antibody prevents transmission of the signal and causes muscle weakness.
