Gene Therapy For Parkinson's Disease Moves Forward In Animals

...stitute and Genetics Institute who was part of the research team. The protein, called GDNF, short for glial cell line-derived neurotrophic factor, is believed to preserve brain cells and could provide protection against Parkinson's disease. But its use has been debated since trials in humans ended last year ...
