Scientists reverse Parkinson’s symptoms in mice — Could humans be next?


Scientists at the University of Sydney have uncovered a malfunctioning version of the SOD1 protein that clumps inside brain cells and fuels Parkinson’s disease. In mouse models, restoring the protein’s function with a targeted copper supplement dramatically rescued movement, hinting at a future therapy that could slow or halt the disease in people.

In mouse models, restoring the protein’s function with a targeted copper supplement dramatically rescued movement, hinting at a future therapy that could slow or halt the disease in people. The research team, led by Professor Kay Double from the Brain and Mind Centre, has spent more than a decade studying the biological mechanisms underpinning the condition, with the aim of finding new treatments to slow or stop its progression. Parkinson's disease is a degenerative neurological disorder in which dopamine-producing cells in the brain die, leading to a range of symptoms including tremors, muscle stiffness, slow movement and impaired balance.
