摘要

IgM单克隆伽玛病在一些运动神经元疾病患者中有报道。部分患者的单克隆IgMs与神经系统中神经节苷GM1、GD1b和糖蛋白共有的碳水化合物表位Gal (β 1-3) GalNAc结合,并与Gal (β 1-3) GlcNAc发生交叉反应。他们也免疫染色脊髓和灰质以及神经肌肉连接处运动神经元的突触前终末。这些抗体在运动神经元疾病中的作用和作用机制正在研究中。

Antibodies to glycoconjugates in human motor neuron disease.

IgM monoclonal gammopathy has been reported in some patients with motor neuron disease. The monoclonal IgMs in several of the patients bind to the carbohydrate epitope Gal (beta 1-3) GalNAc, which is shared by gangliosides GM1 and GD1b and glycoproteins in the nervous system and crossreacted with Gal (beta 1-3) GlcNAc. They also immunostain spinal cord and gray matter and presynaptic terminals of motor neurons at the neuromuscular junction. The role and mechanisms of action of these antibodies in motor neuron disease is under investigation.
