Parkinson’s disease is a neurodegenerative disease that primarily affects dopamine-producing neurons in a certain part of the brain. It is a mobility disorder caused by a degenerative neural system dysfunction. Xinnan Wang, MD, PhD, and her lab, have done extensive research to find treatments for Parkinson's Disease, and have really focused on how Parkinson's creates defects in mitochondrial function. 

Below are articles highlighting their findings:

Scientists Find Potential Diagnostic Tool, Treatment for Parkinson’s Disease
Here, Dr. Wang and her colleagues pinpointed a molecular defect that seems almost universal among patients with Parkinson’s disease and those at a high risk of acquiring it.

When Miro Just Can’t Let Go
This article, published on scienceofparkinsons.com, details Dr. Wang's findings on Miro, a protein which is involved in the removal of old or faulty mitochondria. This relationship with Miro and patients with Parkinson's could be an important biomarker in finding consistent treatment of Parkinson's disease.
