Abstract
Much recent Alzheimer disease research has focused on the mechanism by which amyloid precursor protein is processed to form amyloid β-peptide. Now, a new study suggests that improper clearance of amyloid β-peptide may play just as large a part as amyloid β-peptide production in amyloid deposition (143–150).
