Which senescent cell types in the brain contribute most to neurodegeneration (microglia, astrocytes, oligodendrocyte precursors)?\n2. What senolytic compounds (dasatinib+quercetin, navitoclax, fisetin) show BBB penetration and CNS efficacy?\n3. What is the evidence from animal models linking cellular senescence to Alzheimer's, Parkinson's, and other neurodegenerative diseases?\n4. What are the risks of removing senescent cells in the aging brain (e.g., loss of SASP-mediated repair signals)?\n5. What clinical trials exist or are planned for senolytics in neurodegeneration?","hypotheses":[{"id":"SDA-2026-04-16-hyp-e5bf6e0d","score":0.79,"title":"Metabolic Reprogramming to Reverse Senescence"},{"id":"SDA-2026-04-16-hyp-daadc5c6","score":0.71,"title":"SASP Modulation Rather Than Cell Elimination"},{"id":"SDA-2026-04-16-hyp-4a6e22aa","score":0.7,"title":"Autophagy-Senescence Axis Therapeutic Window"},{"id":"SDA-2026-04-16-hyp-b29129dc","score":0.6,"title":"Oligodendrocyte Precursor Cell Senescence in White Matter Disease"},{"id":"SDA-2026-04-16-hyp-a44afba2","score":0.48,"title":"Apoptosis-Senescence Decision Point Intervention"},{"id":"SDA-2026-04-16-hyp-96ec73b3","score":0.46,"title":"APOE4-Driven Astrocyte Senescence as Primary Target"},{"id":"SDA-2026-04-16-hyp-f460e747","score":0.29,"title":"Selective Microglial Senescence Targeting via TREM2 Modulation"}],"analysis_id":"SDA-2026-04-04-gap-senescent-clearance-neuro","debate_type":"4-persona gap analysis","num_hypotheses":7,"_schema_version":1},"created_at":"2026-04-16T05:54:06.698791-07:00","updated_at":"2026-04-16T05:54:06.698791-07:00","version_number":4,"parent_version_id":null,"version_tag":null,"changelog":null,"is_latest":1,"lifecycle_state":"validated","superseded_by":null,"deprecated_at":null,"deprecated_reason":null,"dependencies":null,"market_price":0.5,"origin_type":"analysis","origin_url":"/analyses/sda-2026-04-04-gap-senescent-clearance-neuro.html","lifecycle_changed_at":"2026-04-16T05:54:06.698791-07:00","citation_count":0,"embed_count":0,"derivation_count":0,"support_count":0,"contradiction_count":0,"total_usage":0.0,"usage_score":0.5,"usage_computed_at":null,"quality_status":"ok","contributors":[],"answers_question_ids":null,"deprecated_reason_detail":null,"deprecated_reason_code":null,"commit_sha":null,"commit_submodule":null,"last_mutated_at":"2026-05-16T14:51:34.657673-07:00","disputed_at":null,"gap_id":null,"mission_id":null,"intrinsic_priority":null,"effective_priority":null,"artifact_id":"70d1a204-c36a-45bd-ace3-f36200986b6d","artifact_dir":null,"primary_filename":null,"accessory_filenames":null,"folder_layout_version":1,"migrated_to_folder_at":null,"hypothesis_id":null,"authorship":{"kind":"human","contributors":[{"role":"author","actor_ref":"SciDEX-Agora-Agent"}]},"epistemic_tier":"T3_provisional","created_by_agent_id":null},"outgoing_links":[],"incoming_links":[],"current_artifact_id":"ART-2026-04-16-b191e481","is_canonical":true,"supersede_chain":["ART-2026-04-16-b191e481"]}
