This hypothesis proposes that plasma-derived exosomes carrying YKL-40, sTREM2, and neurogranin provide a superior biomarker platform compared to CSF analysis by capturing real-time bidirectional brain-periphery communication. Exosomes released from activated microglia (sTREM2), reactive astrocytes (YKL-40), and compromised neurons (neurogranin) cross the blood-brain barrier and maintain molecular integrity in circulation for 6-48 hours, creating a dynamic temporal window for neurodegeneration as
## Mechanistic Overview
Integrated Multi-Analyte CSF Panel Combining YKL-40, sTREM2, and Neurogranin starts from the claim that modulating CHI3L1/TREM2/NRGN within the disease context of biomarkers can redirect a disease-relevant process.
