Huntington's disease (HD) is the most common inherited neurodegenerative disease and is characterized by uncontrolled excessive motor movements and cognitive and emotional deficits. The mutation responsible for HD leads to an abnormally long polyglutamine (polyQ) expansion in the huntingtin (Htt) protein, which confers one or more toxic functions to mutant Htt leading to neurodegeneration. The polyQ expansion makes Htt prone to aggregate and accumulate, and manipulations that mitigate protein misfolding or facilitate the clearance of misfolded proteins tend to slow disease progression in HD models. This article will focus on HD and the evidence that it is a conformational disease.
亨廷顿病（HD）是最常见的遗传性神经退行性疾病，其特征是运动不受控制地过度运动以及认知和情感缺陷。导致 HD 的突变导致亨廷顿蛋白（Htt）中的异常长聚谷氨酰胺（polyQ）扩展，该扩展赋予突变型 Htt 一种或多种毒性功能，导致神经退行性变。polyQ 扩展使 Htt 易于聚集和积累，并且减轻蛋白质错误折叠或促进错误折叠蛋白清除的操作往往会使 HD 模型中的疾病进展减缓。本文将重点介绍 HD 以及它是一种构象疾病的证据。
