Abstract
INTRODUCTION
We systematically characterized plasma protein profiles in cerebral amyloid angiopathy (CAA) using proteomics and identified a hub protein panel for disease diagnosis and risk stratification.
METHODS
A total of 146 patients with probable CAA and 128 community-dwelling controls were prospectively enrolled. Plasma samples underwent proteomic analysis, and the hub proteins were validated in two validation cohorts. Machine learning algorithms were applied to construct and validate the performance of the circulating panel.
RESULTS
We identified 166 differentially expressed proteins in patients with CAA. Six hub proteins were selected to form the circulating panel, demonstrating excellent performance to distinguish patients from controls in all cohorts. Additionally, the risk stratification system derived from the hub protein panel accurately identified patients at high risk for new-onset lobar intracerebral hemorrhage.
DISCUSSION
Our findings revealed distinctive circulating protein signatures in CAA and established a validated hub protein panel aiding in CAA screening and risk stratification.
Highlights
We identified plasma protein signatures in CAA using proteomics.
A circulating hub protein panel was developed and validated, demonstrating high accuracy for disease screening.
The hub protein panel effectively stratified CAA patients according to risk of future intracerebral hemorrhage.
The circulating panel offers potential for CAA screening and risk stratification.
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.
