More than 20 years after the discovery of the parkin gene linked to young-onset Parkinson’s disease, researchers at The Ottawa Hospital and the University of Ottawa may have finally figured out how this mysterious gene protects the brain.

Using human and mouse brain samples and engineered cells, they found that the parkin protein works in two ways. First, it acts like a powerful antioxidant that disarms potentially harmful oxidants in the brain, including dopamine radicals. Second, as the brain ages and dopamine radicals continue to build up, parkin sequesters these harmful molecules in a special storage site within vulnerable nerve cells, so they can continue to function normally throughout our lifespan.

In people with mutations in both copies of the parkin gene, these protective effects are missing, and as a result Parkinson’s develops before the age of 40 years. If confirmed, the results could point the way towards the development of new treatments.

“If we could deliver antioxidants or a healthy copy of the parkin gene into the brains of people with these mutations, this could help slow down or even halt early-onset Parkinson’s,” said co-corresponding author and scientific project manager Dr. Julianna Tomlinson.
