Researchers with the National Institute on Aging Intramural Research Program and Johns Hopkins University School of Medicine have discovered an enzyme that may protect mice brains against stresses believed to contribute to energy loss. This protective enzyme, called SIRT3, is located in the cells mitochondria. It is believed that as we age or develop neurodegenerative diseases such as Alzheimer's the brain cells may not produce sufficient energy to remain fully functional.
Using a new animal model, the researchers took a look at whether the...
