Choosing an animal model for the study of Huntington’s disease.

Pouladi MA, Morton AJ, Hayden MR.

Since the identification of the causative gene in Huntington’s disease (HD), a number of animal models of this disorder have been developed. A frequently asked question is: which of these models most closely recapitulates the human disease? In this Review, we provide an overview of the currently available animal models of HD in the context of the clinical features of the disease. In doing so, we highlight their strengths and limitations for modelling specific symptoms of the disease. This should highlight the animal model that is best suited to address a particular question of interest and, ultimately, to expedite the discovery of treatments that will prevent or slow the progression of HD.
