This challenge targets the hypothesis: **Test: TREM2 enhances amyloid clearance** **Hypothesis Summary:** ## Mechanistic Overview Test: TREM2 enhances amyloid clearance starts from the claim that modulating not yet specified within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Test: TREM2 enhances amyloid clearance starts from the claim that modulating not yet specified within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "TREM2 (Triggering **Falsifiable Predictions:** 1. Pharmacological modulation of TREM2 will alter neurodegeneration markers in validated models by ≥20% 2. Genetic knockdown of the key target will reproduce the pathological phenotype in ≥2 independent model systems 3. Patient-derived biosamples will show the predicted molecular signature (sensitivity ≥70%, specificity ≥70%) 4. Mechanistic intervention at the proposed node will rescue neuronal viability in vitro by ≥30% **Bounty Tier:** $125,500 USD (composite score 0.755) **Challenge Type:** Open — any team may submit experimental evidence supporting or refuting this hypothesis **Success Criteria:** Peer-reviewed evidence demonstrating mechanistic validation of ≥2 of the 4 predictions, with independent replication.
