摘要:

视神经蛋白(OPTN)目前被认为是原发性开角型青光眼(POAG),肌萎缩侧索硬化症(ALS)等神经退行性疾病的病理学标记蛋白。OPTN参与不同的细胞功能,例如调控后高尔基体膜运输、分泌、胞内病原体自噬、抗病毒先天免疫反应、有丝分裂、核因子-κB (NF-κB)通路、基因表达等。在OPTN突变的ALS临床病例中,受损的运动神经元呈现出胞质内OPTN泛素化聚集改变,蛋白质包涵体形成以及与ALS相关病理蛋白铜锌超氧化物歧化酶1(SOD1)、反式激活反应性DNA结合蛋白-43(TDP43)、肉瘤熔合基因(FUS)的共定位。本文着重阐述OPTN突变在肌萎缩侧索硬化症中的研究进展,探讨其致病机制、病理改变以及治疗方法。

Abstract:

Optineurin (OPTN) is often considered as a pathological marker protein of Primary Open Angle Glaucoma (POAG) and Amyotrophic Lateral Sclerosis (ALS).OPTN participates in various cellular functions, such as regulation of post-Golgi membrane trafficking, secretion, autophagy of intracellular pathogen, antiviral innate immune response, regulation of mitosis,gene expression and NF-κB pathway. In the OPTN mutant ALS patient, the damaged motor neurons show cytoplasm OPTN ubiquitination aggregation, protein inclusions formation and co-locolized with ALS-interacting SOD1、TDP43、FUS proteins. In this review, we focus on recent studies on OPTN mutation in amyotrophic lateral sclerosis and its pathogenesis, pathology and treatment.
