Description
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.
Resolution criteria
Resolved when: an immune-atlas analysis maps microglia, astrocyte, and infiltrating immune-cell states across neurodegeneration datasets, anchors results to TREM2 and complement hypotheses, cites source datasets or papers, and creates KG edges connecting immune states, markers, pathways, diseases, and candidate interventions. The gap also needs three to five scored hypotheses or a debate synthesis explaining which inflammatory mechanisms are actionable.
