TREM2 signaling controls the spatial distribution of complement regulators CD55 and CD46 on synaptic membranes, determining which synapses are vulnerable to complement-mediated pruning. Under normal conditions, TREM2 activation promotes the expression and clustering of CD55/CD46 at perisomatic inhibitory synapses through DAM pathway signaling, while maintaining low regulator density at distal excitatory synapses. This creates a protective gradient where inhibitory circuits are preserved while al
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
