Stopping Alzheimer’s: Antibody thwarts disease in mice

Amyloid beta, the waxy protein that litters the brains of Alzheimer’s patients, is like a criminal with many arrests but no convictions. Studies have implicated amyloid plaques in the disease, but nobody has proved that they cause it.

Now, scientists working with mice report that antibodies tailor-made to attack amyloid can wipe it out and reverse an experimental version of Alzheimer’s disease if the intervention begins early enough.
