Amyloid-beta (Aβ) with 40 (Aβ40) and 42 (Aβ42) amino acids, the main components of
amyloid plaques in the Alzheimer's disease (AD) brain, can be measured in human …

Various C‐terminally truncated amyloid β peptides (Aβ) are linked to Alzheimer's disease
(AD) pathogenesis. Cerebrospinal fluid (CSF) concentrations of Aβ38, Aβ40, and Aβ42 were …

Background Amyloid pathology, which is one of the characteristics of Alzheimer's disease
(AD), results from altered metabolism of the beta-amyloid (Aβ) peptide in terms of synthesis …

Amyloid β (Aβ) peptides are important components of plaques in Alzheimer's disease (AD).
A decrease in the CSF concentration of Aβ40 and Aβ42 is a potential biomarker for incident …

Plasma β-amyloid protein (Aβ) isoforms are considered potential biomarkers for Alzheimer's
disease (AD) and dementia. The relation between plasma and cerebrospinal fluid (CSF) …

We quantitated amyloid β proteins 1–40 (Aβ40) and 1–42 (Aβ42), and α1-antichymotrypsin
(ACT) in matched cerebrospinal fluid (CSF) and plasma of 50 patients with probable …

The 42 amino acid form of amyloid-ß (Aß42) plays a key role in the pathogenesis of
Alzheimer's disease (AD) and is a core biomarker for the diagnosis of AD. Numerous studies …

Background A reduced amyloid-β (Aβ) 42/40 peptide ratio in blood plasma represents a
peripheral biomarker of the cerebral amyloid pathology observed in Alzheimer's disease …

To better understand amyloid‐β (Aβ) metabolism in vivo, we assessed the concentration of
Aβ in the CSF and plasma of APPV717F (PDAPP) transgenic mice, a model that develops …

We quantitated amyloid β peptide (Aβ) 38, Aβ40 and Aβ42 levels in matched CSF and
plasma from Alzheimer disease (AD) patients and controls. CSF Aβ38 and Aβ40 levels were …
