From Analysis:

Systemic immune profiling in neurodegeneration: peripheral inflammation as driver and biomarker

How does chronic peripheral inflammation interact with CNS neuroimmune pathways to accelerate neurodegeneration? What are the systemic immune signatures that distinguish AD patients from healthy aging, and can peripheral immune biomarkers predict disease progression or treatment response? How does microglial priming by peripheral cytokines alter the brain's response to amyloid and tau pathology?

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.

Novel Therapeutic Hypotheses: Systemic Immune Profiling in Neurodegeneration

Hypothesis 1: Circulating hs-CRP as a Disease-Modifying Target via Microglial IL-1β Amplification

Description: Elevated peripheral C-reactive protein (hs-CRP) directly primes hippocampal microglia through IL-1β signaling, creating a feed-forward neuroinflammatory loop that accelerates tau hyperphosphorylation. Therapeutic lowering of hs-CRP may restore microglial surveillance and reduce tau pathology propagation.

Expert Evaluation: Systemic Immune Profiling in Neurodegeneration

Executive Summary

The seven hypotheses present a coherent framework linking peripheral immune dysregulation to CNS neurodegeneration, but face significant translational challenges. The fundamental tension is that neuroinflammation-targeting strategies have failed repeatedly in clinical trials (NSAIDs, IL-1 blockade, anti-TNF), suggesting either the wrong targets, wrong timing, or wrong patient populations. I will evaluate each hypothesis against practical criteria.

How Economics Pricing Works

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.
