Myasthenia gravis is an autoimmune disease which results from antibodies that block acetylcholine receptors at the junction between the nerve and muscle. This prevents nerve impulses from triggering muscle contractions.
Acetylcholine[edit | edit source]
Autoantibodies to acetylcholine receptors, alpha subunit have been found in patients with myasthenia gravis. These cross react with herpesvirus glycoprotein D.  Antibodies to acetylcholine receptor and HSV-1 antigens crossreact.
B cells from myasthenia gravis patient stimulated in vitro by Epstein-Barr virus produced acetylcholine autoantibodies. Ongoing EBV infection of the thymus has been posited as a causative agent for the production of aceytlcholine receptor autoantibodies in myasthenia gravis.
