Autoimmune myasthenia gravis (MG) is the prototypic, antibody-mediated neuromuscular disease and is characterized by a decrease in the number of functional acetylcholine receptors (AChR) within the muscle end plate zone of the neuromuscular junction (NMJ). Although the pathophysiology of AChR-mediated myasthenia gravis has been extensively studied over the last 40 years since its original description by Patrick and Lindstrom (Science 180:871-872, 1973), less is known about the much more recently described muscle-specific kinase (MuSK) antibody-mediated MG. MuSK-MG has features clinically distinct from Ach-R MG, as well as a different pattern of response to treatment and a unique immunopathogenesis.
自身免疫性重症肌无力 (MG) 是一种典型的抗体介导的神经肌肉疾病,其特征是在神经肌肉接头 (NMJ) 的肌肉终板区域内功能性乙酰胆碱受体 (AChR) 的数量减少。尽管自 Patrick 和 Lindstrom(Science 180:871-872, 1973)最初描述以来,在过去的 40 年中已经对 AChR 介导的重症肌无力的病理生理学进行了广泛研究,但对于最近描述的肌肉特异性激酶 (MuSK) 抗体介导的 MG 知之甚少。MuSK-MG 在临床上与 Ach-R MG 不同,对治疗的反应模式也不同,免疫发病机制也独特。
