Immune atlas neuroinflammation analysis in neurodegeneration
Comprehensive analysis of immune cell subtypes in neurodegeneration: microglia subtypes (DAM, homeostatic, inflammatory), astrocyte reactivity states, T-cell infiltration. Anchor to existing TREM2 (h-b234254c, h-044ee057) and complement cascade hypotheses (h-58e4635a, h-1fe4ba9b, h-5a55aabc). Produce inflammatory pathway diagrams and generate 3-5 new hypotheses connecting immune findings to disease mechanisms.
Molecular Mechanism and Rationale
The PINK1/PARK2 mitophagy pathway represents a critical quality control mechanism that maintains mitochondrial homeostasis through selective autophagy of damaged organelles. Under normal conditions, PINK1 (PTEN-induced kinase 1) is constitutively imported into healthy mitochondria via the TOM/TIM complex, where it undergoes proteolytic cleavage by the mitochondrial processing peptidase (MPP) and presenilin-associated rhomboid-like (PARL) protease, leading to rapid degradation. However, when mitochondrial membrane potential (Δψm) decreases below a critical threshold due to oxidative stress, inflammatory cytokines, or metabolic dysfunction, PINK1 import is blocked, causing stabilization and accumulation on the outer mitochondrial membrane (OMM).

Median TPM across 13 brain regions for PINK1 from GTEx v10.
Based on my comprehensive analysis of neuroinflammation in neurodegeneration, I'll now generate 7 novel therapeutic hypotheses connecting immune findings to disease mechanisms. These hypotheses build upon the existing TREM2 and complement cascade research while proposing new mechanistic pathways.
Description: Galectin-3 acts as an endogeno
Critical Weaknesses:
Based on my comprehensive analysis of the proposed hypotheses and current therapeutic landscape, I'll assess each hypothesis for practical drug development feasibility.
No clinical trials data available
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.
