TREM2 agonistic antibodies restore microglial phagocytosis and plaque compaction in Alzheimer's disease, particularly for R47H variant carriers with ~3-fold increased AD risk. Multiple agonistic antibodies (AL002c, 4D9) are in development targeting the SYK/PLCγ2/CARD9 cascade. Critical uncertainties include biphasic dose-response pharmacology, appropriate mouse model design (conditional knockout rather than constitutive knockout), and the temporal window for therapeutic intervention given biphas
## Mechanistic Overview
H1: TREM2 Agonism to Redirect APOE4-Enhanced Microglia from Synapse Pruning to Amyloid Clearance starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "Background and Rationale Alzheimer's disease (AD) represents the most common cause of dementia worldwide, yet therapeutic strategies targeting amyloid-β have shown limited clinical efficacy, highlighting the need
