Parkinson's

Discovery provides a tool to track brain cell metabolic changes related to aging and diseases such as Alzheimer's, Parkinson's and Huntington's

A protein that causes coral to glow is helping researchers to light up brain cells that are critical for the proper functioning of the central nervous system. This fluorescent marker protein may shed light on brain cell defects believed to play a role in various neurological diseases. The researchers describe how this marker works in mice. The marker gives scientists the first-ever opportunity to distinguish between energy-producing structures, called mitochondria, in neurons, from mitochondria in other brain cells, called glia. Defects in mitochondria may be part of the process that leads to Alzheimer's and Parkinson's disease.
