Link between two key Alzheimer’s proteins explained

It’s a paradox of Alzheimer’s disease: Plaques of the sticky protein amyloid beta are the most characteristic sign in the brain of the deadly neurodegenerative disease. However, many older people have such plaques in their brains but do not have dementia.

The memory loss and confusion of Alzheimer’s instead is associated with tangles of a different brain protein – known as tau – that show up years after the plaques first form. The link between amyloid and tau has never been entirely clear. But now, researchers at Washington University School of Medicine in St. Louis have shown that people with more amyloid in their brains also produce more tau.

The findings, available March 21 in the journal Neuron, could lead to new treatments for Alzheimer’s, based on targeting the production of tau. Read more.
