Sheng Zhang and colleagues report here the development of a Drosophila model for Huntington’s disease (HD), which recapitulates many of the symptoms seen in humans Deletion of the huntingtin gene in flies leads to progressively impaired mobility, an age-associated reduction in axonal termini complexity and a shortened life span. These neurological symptoms are exacerbated further by expression of the mutant huntingtin protein that is produced in HD patients. (see Journal Club article on page 199).
