Description

This challenge targets the hypothesis: **Direct Toxicity Hypothesis: β-Amyloid Directly Impairs Cholinergic Signaling** **Hypothesis Summary:** ## Mechanistic Overview Direct Toxicity Hypothesis: β-Amyloid Directly Impairs Cholinergic Signaling starts from the claim that modulating CHRNA7, CHRM1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "# Direct Toxicity Hypothesis: β-Amyloid Directly Impairs Cholinergic Signaling ## Mechanistic Overview The Direct Toxicity Hypothesis proposes that soluble β-amyloid (Aβ) oligomers exert their pathogenic effects on cholinergi **Falsifiable Predictions:** 1. Pharmacological modulation of CHRNA7 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:** $126,900 USD (composite score 0.769) **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.
