nervous system
• amyloid beta deposition in the brains is higher than in controls with only Tg(PSEN1)5Dbo and Tg(APP69ff5)3Dbo at 13-14 months of age
• amyloid beta deposition is seen in the cortical parenchyma and in cortical vessels as cerebral amyloid angiopathy
• concentrations of insoluble amyloid beta40 and amyloid beta42 is higher than in controls at 13-14 months of age but not at 3 months
• despite the increase in amyloid beta deposition, APP processing and levels of amyloid beta degrading enzymes are normal, indicating that the increase is due to a disturbance of lysosomal-mediated amyloid beta clearance
• amyloid beta deposition is seen in cortical vessels as cerebral amyloid angiopathy
• activation of astrocytes is enhanced compared to controls with only Tg(PSEN1)5Dbo and Tg(APP69ff5)3Dbo at 1 year of age
