[THE ROLE OF AUTOANTIBODIES TO THE EXTRACELLULAR REGIONS OF IONOTROPIC RECEPTORS IN ETIOLOGY AND PATHOGENESIS OF AUTOIMMUNE DISEASES].

Abstract

In the last years it was shown that autoantibodies to the extracellular regions of the ionotropic receptors, such as glutamate AMPA- and NMDA-receptors, GABAA-receptors, glycine and nicotinic acetylcholine receptors, induce a wide spectrum of autoimmune diseases, including limbic encephalitis, Rasmussen's encephalitis, systemic lupus erythematosus, myasthenia gravis, encephalomyelitis, and stiff-man syndrome. In the review the literature data concerning the autoimmune processes provoking autoantibodies formation to the ionotropic receptors, the epitopes participating in the induction of pathogenic autoantibodies, and the effects of these antibodies on the functions of nervous cells and their role in the development of autoimmune diseases were analyzed and systematized. The possible role of oncology diseases in the generation of autoantibodies to the ionotropic receptors was discussed. Approaches that are currently being developed to inhibit the synthesis of pathogenic autoantibodies and to their neutralization were considered. These approaches may be subsequently used to treat the autoimmune diseases caused by the antibodies to ionotropic receptors.
