Brain-derived Tau in Neurodegenerative Diseases | Beckman Coulter

Brain-derived Tau in Neurodegenerative Diseases

About 80% of the Tau protein found in plasma originates from peripheral tissues, creating a critical need to selectively measure Tau that originates in the central nervous system (CNS). Brain-derived Tau (BD-Tau) is produced exclusively in the brain and can be detected in the CNS and peripheral blood.

Research shows that measuring BD-Tau can accurately identify Alzheimer’s disease (AD)-specific neurodegeneration, distinguishing it from non-AD diseases (i.e., frontotemporal dementia, traumatic brain injury, stroke, multiple sclerosis)1,2
