Selective GluN2A activation or GluN2B inhibition shifts balance from excitotoxic extrasynaptic signaling toward neuroprotective synaptic signaling. Deprioritized due to memantine's modest clinical efficacy and technical challenges in confirming in vivo compartmentalization.

Dimension Scores
How to read this chart:
Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential.
The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength),
green shows moderate-weight factors (safety, competition), and
yellow shows supporting dimensions (data availability, reproducibility).
Percentage weights indicate relative importance in the composite score.

Test Preregistration: Therapeutic Hypotheses in Neurodegeneration
Hypothesis 1: Microglial TREM2 Activation as Therapeutic Target in Alzheimer's Disease
Title: TREM2 agonism will reduce amyloid-associated neurotoxicity by promoting microglial phagocytosis and metabolic reprogramming
Mechanism: TREM2 (Triggering Receptor Expressed on Myeloid Cells 2) is a microglia-specific receptor essential for microglial response to amyloid plaques. Agonist-mediated activation enhances amyloid clearance, reduces dystrophic neurites, and shifts microglia from a disease-associated (DAM) to home
🔍SkepticIdentifies weaknesses, alternative explanations, and methodological concerns▼
Weakest link: R47H is a loss-of-function variant—agonism restores WT signaling, but does pharmacologic agonism recapitulate endogenous activation? The therapeutic window may be narrow.
Confounds:
5xFAD mice have aggressive amyloid deposition; microglial dynamics differ in human AD where plaques form over decades
TREM2 agonism may enhance phagocytosis of vulnerable synapses, not just plaques (PMID 30742032 showed microglial engulfment of excitatory terminals)
AL002c is hypothetica
🎯Domain ExpertAssesses practical feasibility, druggability, and clinical translation▼
The Theorist presented 7 mechanistically-plausible hypotheses; the Skeptic's critiques substantially weakened most. Below I assess feasibility across five dimensions for each surviving hypothesis.
H1: TREM2 Agonism in AD
| Dimension | Assessment | |-----------|------------| | Druggability | Tractable — antibody therapeutics suit cell-surface receptors. AL002c (from Alector) already in Phase II for AD. Fc-mediated agonism is a proven mechanism. | | Biomarkers/Models | Model concern: 5xFAD ha
