Missing link in Parkinson’s disease found | The Source | Washington University in St. Louis
School of Medicine researchers have described a missing link in understanding how damage to the body’s cellular power plants leads to Parkinson’s disease and some forms of heart failure. A mouse heart, in gray, shows signs of heart failure because it is missing a newly discovered key molecule in the process that culls unhealthy mitochondria from cells. Superimposed on the heart is a fruit fly heart tube, shown in color. It shows signs of failure because it is missing another key molecule in mitochondrial quality control.
