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.
近年来研究表明,针对离子型受体细胞外区域的自身抗体,如谷氨酸AMPA受体和NMDA受体、GABAA受体、甘氨酸受体和烟碱型乙酰胆碱受体,可引发多种自身免疫性疾病,包括边缘性脑炎、拉斯穆森脑炎、系统性红斑狼疮、重症肌无力、脑脊髓炎和僵人综合征。本文综述了有关引发离子型受体自身抗体形成的自身免疫过程、参与致病性自身抗体诱导的表位,以及这些抗体对神经细胞功能的影响及其在自身免疫性疾病发生中的作用的文献数据,并进行了系统整理。讨论了肿瘤疾病在离子型受体自身抗体产生中的可能作用。还探讨了目前正在研发的抑制致病性自身抗体合成及其中和作用的方法。这些方法随后可能用于治疗由离子型受体抗体引起的自身免疫性疾病。
