The McBride Laboratory focuses on finding therapies for the neurodegenerative brain disorder, Huntington's disease (HD). HD is a fatal, genetic neurodegenerative disorder caused by a mutation on chromosome 4. The genetic mutation (CAG repeat) in the HTT gene encodes a mutant huntingtin protein (HTT) with an expanded polyglutamine stretch at the N-terminus of the protein. The characteristic hallmarks of HD neuropathology include mutant HTT-containing aggregates and robust cell loss in numerous regions throughout the brain, such as the striatum (comprised of the caudate nucleus and putamen) cortex, thalamus, hypothalamus and the substantia nigra. Clinically, the most obvious symptoms of HD involve involuntary hyperkinetic movements of the arms, legs, and face, known as chorea. Additionally, HD patients suffer from cognitive deficits, particularly those involving working (short-term) memory, and personality changes including emotional disturbances such as depression, anxiety, impulsivity and apathy.
Currently, projects in the McBride Laboratory focus on using a technique known as RNA interference to shut down expression of the disease causing gene:
RNA interference in the HD mouse and non-human primate striatum to improve motor and cognitive symptoms (direct brain injection)
RNA interference in the HD mouse cortex to improve anxiety and depressive symptoms (direct brain injection)
CNS wide delivery of RNA interference in the HD mouse brain (delivery into vasculature or CSF)
Another focus of the McBride Laboratory has been the creation of a non-human primate model of HD, which recapitulates several of the neuropathological changes and behavioral symptoms seen in human HD patients. Currently, the lab is investigating changes in brain connectivity in this new model using diffusion tensor imaging and resting state functional MRI.
The McBride Lab has recently been involved in a large effort at the ONPRC to characterize a new, genetic model of the neurodegenerative disorder, Batten Disease (BD) in the Japanese Macaque Colony. BD affected animals show key genetic, pathological and behavioral manifestations of disease that seen in human children suffering from BD.
The goal with both the HD and BD models will be to use them to better understand disease progression, to develop biomarkers of disease progression and to assess viable therapies that can translate into the clinic to help human patients suffering from these fatal diseases.
