High risk. The Expert identifies a fatal flaw: CD38 is predominantly expressed in peripheral immune cells (B cells, T cells, NK cells), not microglia. The cited 3-4 fold increase in PD substantia nigra microglia may reflect perivascular macrophage infiltration rather than intrinsic microglial CD38. Multiple clinical-stage CD38 inhibitors exist (evobrutinib approved for MS), but none are being developed for neurodegeneration. This hypothesis should not proceed without microglial-specific CD38 val
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.
