Reducing canonical Wingless/Wnt signaling pathway confers protection against mutant Huntingtin toxicity in Drosophila.

Huntington's disease (HD) is a genetic neurodegenerative disease characterized by movement disorders, cognitive decline and neuropsychiatric symptoms. HD is caused by expanded CAG tract within the coding region of Huntingtin protein. Despite major insights into the molecular mechanisms leading to HD, no effective cure is yet available.

Increased energy metabolism rescues glia-induced pathology in a Drosophila model of Huntington's disease.

Huntington's disease (HD) is a polyglutamine (polyQ) disease caused by an expanded CAG tract within the coding region of Huntingtin protein. Mutant Huntingtin (mHtt) is ubiquitously expressed, abundantly in neurons but also significantly in glial cells. Neuron-intrinsic mechanism and alterations in glia-to-neuron communication both contribute to the neuronal dysfunction and death in HD pathology.
