"They've produced a picture of what's going on that no one could have anticipated just a few years ago," saysA protein called Reelin keeps popping up in brains that resist aging and Alzheimer’s By comparing cells taken at different stages of Alzheimer's, scientists were able to create a timeline showing how the disease alters the brain.
"We were looking for vulnerable cell populations, for example particular types of neurons that might be specifically lost early in disease," Lein says.
