Abstract
A monoclonal anti-idiotypic antibody against an anti-acctylcholine receptor antibody from a patient with myasthenia gravis was shown to bind the cholinergie ligand α-bungarotoxin. This binding could be inhibited by other cholinergic ligands. boih antagonists und agonists. The anti-idioiype was also able to elicit the production of anti-receptor antibodies in mice Thus, the anti-idiotype had functional properties similar to those of the original antigen, the acetylcholine receptor.
