亨廷顿氏病(HD)是一种复杂而严重的疾病,其特征是神经元的逐渐和进行性丧失,主要发生在纹状体中,导致与该病理相关的典型运动和认知障碍。亨廷顿舞蹈症是由编码亨廷顿蛋白的基因外显子1上高度多态性CAG三核苷酸重复扩增引起的。自从第一次发现亨廷顿蛋白基因以来,对大量体外和体内模型的研究已经深入了解了与突变蛋白表达相关的毒性事件。在这篇综述中,我们将总结在表征HD神经元变性的信号通路方面取得的进展。我们将强调在HD患者中观察到的主要负责形成聚集体的年龄依赖性蛋白质平衡丧失。还将讨论最有希望的分子靶点,以发展药物干预。
Huntington's disease (HD) is a complex and severe disorder characterized by the gradual and the progressive loss of neurons, predominantly in the striatum, which leads to the typical motor and cognitive impairments associated with this pathology. HD is caused by a highly polymorphic CAG trinucleotide repeat expansion in the exon-1 of the gene encoding for huntingtin protein. Since the first discovery of the huntingtin gene, investigations with a consistent number of in-vitro and in-vivo models have provided insights into the toxic events related to the expression of the mutant protein. In this review, we will summarize the progress made in characterizing the signaling pathways that contribute to neuronal degeneration in HD. We will highlight the age-dependent loss of proteostasis that is primarily responsible for the formation of aggregates observed in HD patients. The most promising molecular targets for the development of pharmacological interventions will also be discussed.
