    Figure2. Beta-amyloid(1-42) antibodies (GMP-h-Aβ42-Ab02 and GMP-h-Aβ42-Ab01) established a standard curve by chemiluminescence method, and the detection range of Aβ42 was 100-1700 pg/mL.

    Understanding Beta Amyloid

    The 2023 Alzheimer's Association International Conference (AAIC) released a draft proposal for AD diagnostic standards, which introduces blood-based biomarker testing for the first time. AD can be diagnosed through plasma markers such as Aβ42, Aβ40, P-tau181, P-tau217, P-tau231, NFL, GFAP (as shown in the table above). These markers have not yet been subjected to large-scale clinical studies, and relevant groups need to be Do further analysis. For the diagnosis of AD, it is necessary to rely on comprehensive methods such as clinical manifestations and imaging.
    Aβ40 polypeptide and Aβ42 polypeptide are common forms found in human cerebrospinal fluid and serum. It is generally believed that Aβ42 peptide has stronger neurotoxicity and is more prone to aggregation. Changes in Aβ42 peptide concentration in human cerebrospinal fluid and blood are associated with Alzheimer's disease.
    Beta Amyloid is produced by the hydrolysis of amyloid precursor protein (APP) by β and γ secretases and is composed of 38-43 amino acids with toxic effects (as shown on the right ).

    Eli Lilly's new drug Donanemab is an investigational drug for the treatment of AD. It is a specific antibody targeting the N-terminal pyroglutamate Aβ epitope of amyloid plaques. Donanemab antibody can significantly reduce blood pTau217 levels. A significant decrease in plasma pTau217 levels was observed after 12 weeks of treatment with donanemab compared with placebo and was sustained throughout the 76 weeks of the study. Mean plasma pTau217 levels in the donanemab treatment group decreased by 23% from baseline. In contrast, mean plasma pTau217 levels in the placebo group continued to increase by 6% from baseline to the end of the study, as shown below [7]. pTau217 may become a companion diagnostic indicator in the treatment of AD by Donanemab

    Target/Biomarker 정보

    Easily accessible biomarkers are needed for the early identification of individuals at risk of developing Alzheimer's disease (AD) in large population screening strategies. Low plasma Aβ42/40 was associated with more pronounced decline in cognitive function (measured by multiple outcomes) over time. Findings suggest that plasma Aβ42/40 may be used to identify people at risk of cognitive decline, being an alternative to more complex and expensive measures, such as positron emission tomography imaging or cerebrospinal fluid measurement.
