Resumen de: WO2022013286A1

A method for detecting p217+tau in blood-based samples from a subject with high sensitivity, accuracy, and precision. The assay comprises contacting a sample with a capture antibody directed against a p217+tau epitope to bind the capture antibody to p217+tau peptides in plasma to form antibody-peptide complexes, and separately contacting the antibody-peptide complexes with a detection antibody to bind the detection antibody to the antibody-peptide complexes. The amount of p217+tau is determined by detecting the detection antibody. The amount of p217+tau detected is used to determine whether the subject has tauopathy or is at risk of developing tauopathy, or whether the subject has amyloidogenic disease or is at risk of developing amyloidogenic disease when the amount of p217+tau peptides is above a predetermined threshold value. The method has improved sensitivity such that the predetermined threshold value is above a Lower Limit of Quantification and/or Lower Limit of Detection of the assay.

In order to identify a blood biomarker molecule that makes it possible to distinguish between a dementia patient and a healthy subject and provide a dementia testing method that uses the quantity of said molecule as an indicator, the ECRG4 positivity rate and concentration was detected in blood plasma of dementia patients, patients with mild cognitive impairment, and non-dementia patients or the like. As results, although ECRG4 was detected in the blood plasma of 50% of dementia patients and patients with mild cognitive impairment, ECRG4 was not detected in 95% of the non-dementia patients. It was also discovered that the blood plasma level of ECRG4 in dementia patients and MCI patients was far higher than in non-dementia patients, and ECRG4 is extremely effective as a blood biomarker molecule for dementia.
