APOE4 binds TREM2 with lower affinity than APOE3, driving microglia toward a neurodegenerative phenotype with failed DAM1→DAM2 transition. Anti-APOE4 antibodies (3H9) shift microglial phenotype to neuroprotective state. This hypothesis benefits from APOE4 being the strongest AD genetic risk factor after PSEN1/APP. However, the single-cell transcriptomics literature now identifies at least four microglial states beyond the binary DAM framework, suggesting the mechanism is oversimplified.
## Mechanistic Overview
Test: TREM2 enhances amyloid clearance starts from the claim that modulating not yet specified within the disease context of neurodegeneration can redirect a disease-relevant process.
