Biomarkers are playing an increasingly important role in the diagnosis of Alzheimer’s disease.
The FDA has recently published guidelines that endorse their use5, and the National Institute on Aging—Alzheimer’s Association (NIA-AA) has created a research framework that defines Alzheimer’s disease as a biological process characterized by associated biomarkers6. These steps have the potential to evolve Alzheimer’s Disease (AD) diagnostics from a clinically based diagnosis of exclusion to a biological basis that relies on biomarkers in a context of supporting clinical evidence.
In AD, tau protein, contained within neurons, is abnormally phosphorylated and aggregated into bundles of filaments. There are pathological hallmarks, specifically the presence of intracellular neurofibrillary tangles2, which are formed by the abnormal accumulation of hyperphosphorylated tau protein and can be detected 10-15 years before symptom onset3,4. Threonine 181 is one of the phosphorylation sites of human tau protein (pTau181) and is a specific biomarker for AD. pTau181 has been found to be more strongly associated with markers of AD than total tau and can be detected in both the CSF and plasma of patients.
Quanterix currently offers several options for screening pTau biomarkers in samples.
