Outline of Final Research Achievements

Deposition of amyloid β-peptide (Aβ) in the brain parenchyma and cerebral vessels is closely associated with Alzheimer’s disease (AD). Aβ is generated from the amyloid precursor protein (APP) by multiple proteases. Our previous analysis of endothelial APP770 has shown that its O-glycosylated form is preferentially processed to generate Ab. In this study, we have visualized O-glycan with GalNAz and observed the intracellular trafficking of O-glycosylated APP770 by super-resolution microscopic analysis.
