NOT RECOMMENDED. Critical safety contraindications: PU.1 knockout is embryonic lethal in mice; PU.1 haploinsufficiency in humans causes neutropenia and immunodeficiency. The hypothesis contains a mechanistic paradox: Keren-Shaul et al. (PMID:29445926) demonstrates PU.1 directly regulates TREM2 expression and is REQUIRED for DAM formation. Degrading PU.1 would eliminate the protective DAM state entirely, contradicting therapeutic intent. PROTAC chemistry is validated (ARV-471, ARV-110), but this
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.
Convergent vs Divergent Predictions
