Anti-APOE antibody removes amyloid plaques (IMAGE) Washington University School of Medicine Caption Amyloid deposits (blue) in mouse brain tissue and blood vessels are reduced after treatment with an antibody that targets the protein APOE (right), a minor component of amyloid deposits, compared to a placebo antibody (left). Amyloid deposits in the brain increase the risk of dementia and strokes. Researchers at Washington University School of Medicine in St. Louis have identified an antibody that clears amyloid deposits from the brain without raising the risk of brain bleeds.
