Research released today provides evidence that a cure for Parkinson's disease could lie just inside the nose of patients themselves. The Griffith University study published today (Thursday 9am US East Coast) in the journal Stem Cells found that adult stem cells harvested from the noses of Parkinson's patients gave rise to dopamine-producing brain cells when transplanted into the brain of a rat.
The debilitating symptoms of Parkinson's such as loss of muscle control are caused by degeneration of cells that produce the essential chemical dopamine in the brain. Current drug therapies replace dopamine in the brain, but these often become less effective after prolonged use. The discovery is the work of the National Centre for Adult Stem Cell Research, part of Griffith's Eskitis Institute for Cell and Molecular Therapies.
