title: Mechanisms of neuronal cell death in Huntington's disease.
abstract: Huntington's disease (HD) is a genetically dominant neurodegenerative condition caused by an unique mutation in the disease gene huntingtin. Although the Huntington protein (Htt) is ubiquitously expressed, expansion of the polyglutamine tract in Htt leads to the progressive loss of specific neuronal subpopulations in HD brains. In this article, we will summarize the current understanding on mechanisms of how mutant Htt can elicit cytotoxicity, as well as how the selective sets of neuronal cell death occur in HD brains.
