Key protein found for brain's dopamine-producing neurons

Article Abstract:

Swedish researchers Thomas Perlmann and Lars Olson found that the gene Nurr1 and the protein it codes for are essential for development of dopamine- producing brain cells. The findings could lead to treatment or prevention of Parkinson's disease, which results from degeneration of the dopamine cells.
