Salk Scientists Reveal How Brain Cells in Alzheimer’s Go Awry, Lose their Identity

Stembook: Salk Scientists Reveal How Brain Cells in Alzheimer’s Go Awry, Lose their Identity
New technique models brain cells in older patients more accurately than ever before

San Diego, CA, USA – Despite the prevalence of Alzheimer’s, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists at the Salk Institute have uncovered new insights into what goes awry during Alzheimer’s by growing neurons that resemble—more accurately than ever before—brain cells in older patients. And like patients themselves, the afflicted neurons appear to lose their cellular identity.
