From Analysis:
The debate noted clinical failures of TNF-α and IL-6 inhibitors in AD despite their cardiovascular success and shared inflammatory pathways. This paradox suggests unknown mechanistic differences that could inform therapeutic design. Source: Debate session sess_SDA-2026-04-04-gap-neuro-microglia-early-ad-20260404 (Analysis: SDA-2026-04-04-gap-neuro-microglia-early-ad-20260404)
In AD, blocking TNF-α/IL-6 triggers compensatory upregulation of alternative inflammatory cascades (IL-1β, NLRP3) that don't exist in cardiovascular disease. This creates therapeutic resistance unique to neuroinflammation.

Based on the clinical paradox of TNF-α and IL-6 inhibitor failures in Alzheimer's disease despite their cardiovascular success, I'll generate novel therapeutic hypotheses that could explain these mechanistic differences:
I'll critically evaluate each hypothesis, identifying specific weaknesses, counter-evidence, and suggesting experiments to test or falsify them.
Specific Weaknesses:
I'll assess the practical feasibility of each hypothesis, focusing on druggability, existing compounds, competitive landscape, and development practicalities.

Freshness score = exp(-age×ln2/5): halves every 5 years. Green >0.6, Amber 0.3–0.6, Red <0.3.
No citation freshness data yet. Export bibliography — run scripts/audit_citation_freshness.py to populate.
Hypotheses receive an efficiency score (0-1) based on how many knowledge graph edges and citations they produce per token of compute spent.
High-efficiency hypotheses (score >= 0.8) get a price premium in the market, pulling their price toward $0.580.
Low-efficiency hypotheses (score < 0.6) receive a discount, pulling their price toward $0.420.
Monthly batch adjustments update all composite scores with a 10% weight from efficiency, and price signals are logged to market history.
Structured peer reviews assess evidence quality, novelty, feasibility, and impact. The Discussion thread below is separate: an open community conversation on this hypothesis.
