Myasthenia gravis (MG) and experimental autoimmune myasthenia gravis (EAMG) are caused by antibody-mediated autoimmune responses to muscle nicotinic acetylcholine receptors (AChRs) that impair neuromuscular transmission thereby causing muscle weakness. Previously, we discovered that i. p. injection of a therapeutic vaccine consisting of bacterially-expressed cytoplasmic domains of human AChR subunits reduced development of chronic EAMG in rats. Here we show that immunization with the therapeutic vaccine in adjuvant does not induce EAMG, thus is safe. Potency and efficacy of the therapeutic vaccine were greatly increased by administering repeated low doses subcutaneously in incomplete Freund’s adjuvant. Onset of chronic EAMG could be prevented. Established chronic EAMG could be rapidly reversed, modeling therapy of chronic MG. Therapy reduced pathological antibodies assayed by immune precipitation of a main immunogenic region chimera. Successfully treated rats exhibited long-term resistance to re-induction of EAMG, modeling a lasting cure of MG. A long-term effect of therapy was to change isotype of the pathogenic antibody response from IgG2b that fixes complement to IgG1 that does not. Prevention and reversal of chronic EAMG was not caused by the isotype switch, but the isotype switch may contribute to resistance to reinduction of EAMG. Immunization with AChR cytoplasmic domains in adjuvant is promising as a safe, antigen-specific, potent, effective, rapidly acting, and long lasting approach to therapy of MG.
