Genetic ‘hotspots’ that speed up and slow down brain aging could provide new targets for Alzheimer’s drugs
Researchers from a USC-led consortium have discovered 15 “hotspots” in the genome that either speed up brain aging or slow it down — a finding that could provide new drug targets to resist Alzheimer’s disease and other degenerative brain disorders, as well as developmental delays. The research appears online today in Nature Neuroscience. “The big […]
