Mass spectrometric characterization of brain amyloid beta isoform signatures in familial and sporadic Alzheimer’s disease
Open accessAbstract
A proposed key event in the pathogenesis of Alzheimer's disease (AD) is the formation of neurotoxic amyloid beta (Abeta) oligomers and amyloid plaques in specific brain regions that are affected by the disease. The main plaque component is the 42 amino acid isoform of Alphabeta (Abeta1-42), which is thought to initiate plaque formation and AD pathogenesis. Numerous isoforms of Abeta, e.g., Abeta1-42, Abeta1-40 and the 3-pyroglutamate derivate of Abeta3-42 (pGluAbeta3-42), have been detected in the brains of sporadic AD (SAD) and familial AD (FAD) subjects. However, the relative importance of these isoforms in the pathogenesis of AD is not fully understood. Here, we report a detailed study using immunoprecipitation in combination with mass spectrometric analysis to determine the Abeta isoform pattern in the cerebellum, cortex and hippocampus in AD, including subjects with a mutation in the presenilin (M146V) or amyloid precursor protein (KM670/671NL) genes, SAD subjects and non-demented controls. We show that the dominating Abeta isoforms in the three different brain regions analyzed from control, SAD, and FAD are Abeta1-42, pGluAbeta3-42, Abeta4-42 and Abeta1-40 of which Abeta1-42 and Abeta4-42 are the dominant isoforms in the hippocampus and the cortex in all groups analyzed, controls included. No prominent differences in Abeta isoform patterns between FAD and SAD patients were seen, underscoring the similarity in the amyloid pathology of these two disease entities.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
