Site-specific glycosylation patterns on circulating TREM2 ectodomain fragments distinguish senescent from activated microglia states in neurodegeneration. Unlike proteolytic cleavage ratios, this approach leverages differential glycosyltransferase activity (ST6GAL1, MGAT5) that occurs during microglial senescence transitions. Senescent microglia exhibit altered N-linked glycan branching and sialylation on TREM2 before ectodomain shedding, creating distinct glycoform signatures detectable in plas
## 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.
