Strongest mechanistic support among all hypotheses. TREM2-TYROBP signaling for DAM transition well-established. AL002 Phase 2 readout (2025) will be pivotal. Skeptic correctly identifies that APOE4 may act downstream of TREM2, requiring genetic epistasis studies. Expert confirms TREM2 agonism has best tractability; ABCA1 agonists problematic due to hepatotoxicity. APOE protein replacement (Voyager) and TREM2 antibodies provide multiple development paths.
## Mechanistic Overview
TREM2-Dependent Astrocyte-Microglia Cross-talk in Neurodegeneration starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli
