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.
