A new model of experimental auto-immune myasthenia gravis. 1985

M L Souan, and M Geffard

Experimental auto-immune myasthenia gravis (EAMG) was observed in rabbits during the time course of immunization with an acetylcholine (ACh) conjugate: choline-glutaryl-protein. This synthesized antigenic determinant mimics the molecular structure of ACh. The presence of both anti-ACh and auto-anti-idiotypic antibodies was demonstrated. These latter antibodies recognized the ACh receptor, and could have been the triggering agents in this auto-immune condition. Clinical and electromyographic investigations confirmed the myasthenic symptomatology observed after immunization with the ACh conjugate.

UI	MeSH Term	Description	Entries
D007130	Immunoglobulin Idiotypes	Unique genetically-controlled determinants present on ANTIBODIES whose specificity is limited to a single group of proteins (e.g., another antibody molecule or an individual myeloma protein). The idiotype appears to represent the antigenicity of the antigen-binding site of the antibody and to be genetically codetermined with it. The idiotypic determinants have been precisely located to the IMMUNOGLOBULIN VARIABLE REGION of both immunoglobin polypeptide chains.

D009157	Myasthenia Gravis	A disorder of neuromuscular transmission characterized by fatigable weakness of cranial and skeletal muscles with elevated titers of ACETYLCHOLINE RECEPTORS or muscle-specific receptor tyrosine kinase (MuSK) autoantibodies. Clinical manifestations may include ocular muscle weakness (fluctuating, asymmetric, external ophthalmoplegia; diplopia; ptosis; and weakness of eye closure) and extraocular fatigable weakness of facial, bulbar, respiratory, and proximal limb muscles. The disease may remain limited to the ocular muscles (ocular myasthenia). THYMOMA is commonly associated with this condition.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.
