    • Provided are isolated MOG isoforms generated in vivo by exon splicing and that contribute to phenotypic diversity in the peripheral and central nervous systems. Presented herein are transcriptomic analyses for a gene expressed only in mammalian nervous system, myelin oligodendrocyte glycoprotein (MOG). Complex splicing patterns were exclusively found in primates and not in mice. Primate-specific transcripts predicted the existence of multiple MOG isoforms including truncated intra-membranous and/or alternate cytoplasmic domains, and soluble secreted proteins with AIu motifs. The multitude of MOG isoforms is predictive of functions unique to primates, including humans, with regards to maintenance of myelin structure, intracellular signaling, and/or expression of CNS autoimmunity via exposure of specific epitope determinants. Differential expression of MOG isoforms along the neuroaxis is correlative of the broad variability of phenotypes that characteristic of the CNS demyelinating disorder multiple sclerosis. MOG splice variants, isoforms, antibodies, and methods presented herein may be suitably employed for the identification, characterization, and treatment of diseases including, but not limited to, demyelinating and other neurodegenerative, infectious, inflammatory, inherited, and metabolic disorders such as multiple sclerosis (MS) and Alexander's disease.
    • 提供的是通过外显子剪接在体内产生的分离的MOG同种型,并且促成外周和中枢神经系统中的表型多样性。 本文提供了仅在哺乳动物神经系统髓鞘少突胶质细胞糖蛋白(MOG)中表达的基因的转录组分析。 复杂的拼接模式只在灵长类动物中发现,而不是在小鼠中发现。 灵长类特异性转录物预测存在多种MOG同种型,包括截短的膜内和/或替代胞质结构域,以及具有AIu基序的可溶性分泌蛋白。 众多的MOG同种型对于灵长类动物(包括人类)来说独特的功能是关于维持髓磷脂结构,细胞内信号传导和/或通过暴露特定的表位决定簇而表达的CNS自身免疫性的预测。 沿着神经轴的MOG同种型的差异表达与CNS脱髓鞘疾病多发性硬化症的特征的表型广泛变异性相关。 本文提供的MOG剪接变体,同种型,抗体和方法可适用于鉴定,表征和治疗疾病,包括但不限于脱髓鞘和其它神经退行性疾病,传染性疾病,炎症性疾病,遗传性疾病和代谢疾病,例如多发性 硬化症(MS)和亚历山大病。
