## Mechanistic Overview
TREM2-Dependent Microglial Phagocytosis Acts as a Strain Selection Filter starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "# TREM2-Dependent Microglial Phagocytosis Acts as a Strain Selection Filter in Tauopathy Progression ## A Comprehensive Mechanistic Hypothesis The triggering receptor expressed on myeloid cells 2 (TREM2) occupies a central position in m
**Molecular Mechanism and Rationale**
The molecular basis for GPC4/HSPG-mediated tau uptake involves a sophisticated multi-protein complex that functions as a conformational strain selector at the neuronal membrane. Glypican-4 (GPC4), a glycosylphosphatidylinositol (GPI)-anchored heparan sulfate proteoglycan, serves as the primary cell surface receptor through its highly sulfated heparan sulfate (HS) chains that directly interact with the microtubule-binding repeat (MTBR) domains of tau protein
