Site-specific glycosylation patterns on circulating TREM2 ectodomain fragments reflect the metabolic state and activation history of CNS microglia, serving as predictive biomarkers for anti-neuroinflammatory therapeutic responses. The hypothesis posits that microglial priming states differentially regulate glycosyltransferase expression (particularly ST6GAL1, MGAT5, and FUT8), leading to distinct N-linked and O-linked glycan signatures on TREM2 ectodomains shed into circulation. Unlike CSF fragm
This hypothesis proposes that incorporating Parent B's mechanistically precise site-specific TREM2 fragment ratio analysis (N-terminal vs C-terminal fragments reflecting ADAM10/17 protease activity) into Parent A's robust multi-analyte framework creates a superior biomarker panel for detecting microglial priming states. The approach combines TREM2 fragment ratios with YKL-40 (neuroinflammatory priming) and neurogranin (synaptic vulnerability) using a weighted algorithm that leverages the specifi
