New animal model gives insights into mechanisms of Parkinson's disease pathogenesis
In Parkinson's disease, the protein "alpha-synuclein" aggregates and accumulates within neurons. Specific areas of the brain become progressively affected as the disease develops and advances. The mechanism underlying this ...
