Huntington's Disease Model 

Transgenic R6/2 mice [B6CBA-Tg(HDexon1)62Gpb/1J] with CAG repeat expansion (~125 repeats) in huntington gene exon 1 is the most commonly used model to assess compound efficacy for alleviating the deficits of the phenotype in short and longitudinal studies. Charles River’s Behavioral and Cognitive Test Panel can be supplemented with tests modeling psychiatric symptoms of the disease. In vivo profiling of striatal metabolites with Magnetic Resonance Spectroscopy provides data for metabolic changes by compound, and Magnetic Resonance Imaging of brain volumetry indications for effects on atrophy. All studies can be customized according to client needs.
