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 might have finally found out how this strange gene protects the brain.
Using human and mouse brain samples and engineered cells, they discovered that the parkin protein operates in 2 ways. Initially, it imitates a powerful anti-oxidant that disarms potentially harmful oxidants in the brain, consisting of dopamine radicals. Second, as the brain ages and dopamine radicals continue to build up, parkin sequesters these hazardous particles in an unique storage website within susceptible afferent neuron, so they can continue to work usually throughout our lifespan.
In individuals with mutations in both copies of the parkin gene, these protective results are missing, and as a result Parkinson’s establishes prior to the age of 40 years. If verified, the results could point the method towards the advancement of brand-new treatments.
“If we might deliver antioxidants or a healthy copy of the parkin gene into the brains of people with these mutations, this might help slow down or perhaps stop early-onset Parkinson’s,” stated co-corresponding author and scientific job manager Dr. Julianna Tomlinson.
“What we do not understand yet is whether such a technique might also benefit people with late-onset Parkinson’s that is not connected to the parkin gene,” added co-corresponding author Dr. Michael Schlossmacher, neurologist and Director of Neuroscience at The Ottawa Medical facility. “We aspire to examine this.”
