In this study, we report a detailed analysis of the different variants of amyloid-β (Aβ) peptides in the brains and the cerebrospinal fluid from APP23 transgenic mice, expressing amyloid precursor protein with the Swedish familial Alzheimer disease mutation, at different ages. Using one- and two-dimensional gel electrophoresis, immunoblotting, and mass(More)
An early role of amyloid-β peptide (Aβ) aggregation in Alzheimer's disease pathogenesis is well established. However, the contribution of intracellular or extracellular forms of Aβ to the neurodegenerative process is a subject of considerable debate. We here describe transgenic mice expressing Aβ1-40 (APP47) and Aβ1-42 (APP48) with a cleaved signal sequence(More)
Inhibition of β-secretase (BACE1) is a key therapeutic approach in Alzheimer's disease (AD), as BACE1 initiates amyloid-β (Aβ) cleavage from the β-amyloid precursor protein (APP). As Aβ reductions in mice lacking one BACE1 allele diverged considerably between studies we investigated the effect of BACE1 knock-out in more detail. With both BACE1 alleles the(More)
Heterologous expression of the functional amyloid beta (Aβ) antibody β1 in the central nervous system was engineered to maximize antibody exposure in the brain and assess the effects on Aβ production and accumulation in these conditions. A single open reading frame encoding the heavy and light chains of β1 linked by the mouth and foot virus peptide 2A was(More)
