Scientists identify protein that spurs formation of Alzheimer's plaques

In Alzheimer's disease, the problem is beta-amyloid, a protein that accumulates in the brain and causes nerve cells to weaken and die. Drugs designed to eliminate plaques made of beta-amyloid have a fatal problem: they need to enter the brain and remove the plaques without attacking healthy brain cells.

The findings are reported in the Sept. 2 issue of the journal Nature.
