The relationship of soluble tau species with Alzheimer's disease amyloid plaque removal and tau pathology
BACKGROUND
Tau-derived cerebrospinal fluid (CSF) biomarkers correlate with amyloid-beta (Aβ) plaques or tau tangles in Alzheimer's disease (AD). This study assessed the effects of long-term anti-Aβ antibodies on amyloid plaques, tau tangles, and CSF tau species to determine the relationships between them.
METHODS
A post-hoc analysis of the DIAN-TU-001 trial (NCT01760005) examined 142 participants at risk for dominantly inherited AD randomized to solanezumab (n = 50), gantenerumab (n = 52), or placebo (n = 40). High-resolution mass spectrometry quantified CSF tau species over four years.
RESULTS
Phosphorylated tau (p-tau) species (153, 181, 217, 231) increased early in preclinical AD but were reduced with gantenerumab-mediated Aβ plaque reduction. Nearly a decade later, MTBR-tau243 and p-tau205 increased, showing no association with Aβ reduction, aligning with tau tangle pathology progression.
DISCUSSION
Initially changing soluble p-tau species track Aβ plaque reduction, while ptau205 and MTBR-243 reflect tau tangle pathology, informing different pathways of therapeutic strategies.
Highlights
p-tau217 and p-tau231 correlate with Aβ-PET and respond to Aβ-plaque lowering therapies.
Aβ immunotherapy trials support a direct link between p-tau changes and Aβ plaques
Gantenerumab reduces Aβ plaques but does not affect tau NFT-related biomarkers.
Blood-based p-tau217 assays may provide a non-invasive tool to monitor Aβ therapies.
MTBR-tau243 strongly correlates with tau PET and tracks NFT pathology progression.
Further studies are needed to validate tau biomarkers for tracking NFT-targeting therapies.
期刊介绍：
Alzheimer's & Dementia is a peer-reviewed journal that aims to bridge knowledge gaps in dementia research by covering the entire spectrum, from basic science to clinical trials to social and behavioral investigations. It provides a platform for rapid communication of new findings and ideas, optimal translation of research into practical applications, increasing knowledge across diverse disciplines for early detection, diagnosis, and intervention, and identifying promising new research directions. In July 2008, Alzheimer's & Dementia was accepted for indexing by MEDLINE, recognizing its scientific merit and contribution to Alzheimer's research.
