Plaques of a brain protein called amyloid beta are a characteristic sign of Alzheimer’s disease. But nestled within the plaques are small amounts of another Alzheimer’s protein: APOE. Now, researchers at Washington University School of Medicine have shown that an antibody not only targets APOE for removal but sweeps away plaques in mice. The findings could lead to a way to halt the brain damage triggered by amyloid plaques while the disease is still in its early stages, perhaps before symptoms a…
