Transgenic Huntington’s disease monkeys display a full spectrum of symptoms resembling the human disease, ranging from motor problems and neurodegeneration to emotional dysregulation and immune system changes, scientists at Yerkes National Primate Research Center, Emory University report.

The results, published online in the journal Brain, Behavior and Immunity, strengthen the case that transgenic Huntington’s disease monkeys could be used to evaluate emerging treatments (such as this) before launching human clinical trials.

“Identifying emotional and immune symptoms in the HD monkeys, along with previous studies demonstrating their cognitive deficits and fine motor problems, suggest the HD monkey model embodies the full array of symptoms similar to human patients with the disease,” says Yerkes research associate Jessica Raper, PhD, lead author of the paper.
