"synthesis_summary": "The synthesis reveals a critical need for precision in TREM2-targeted therapeutic development, with the splicing-based rescue therapy emerging as the most viable near-term approach due to its strong mechanistic foundation, established delivery platforms (ASOs), and clear patient stratification strategy. The stage-dependent modulation strategy, while conceptually appealing, faces significant challenges in biomarker development, safety validation, and regulatory complexity that currently limit its feasibility. The remaining hypotheses suffer from fundamental gaps in mechanistic understanding, technological limitations, or safety concerns that prevent clinical translation with current knowledge and capabilities.\n\nThe knowledge graph analysis illuminates TREM2's central role as a regulatory hub connecting microglial activation, neuroinflammation, and neurodegeneration, but also highlights the complexity of context-dependent functions that make therapeutic targeting challenging. Critical knowledge gaps include the temporal dynamics of TREM2 function across disease progression, tissue-specific requirements for different brain regions, and the long-term consequences of sustained TREM2 modulation. Future therapeutic development should prioritize biomarker discovery for patient stratification, safety validation in chronic treatment models, and mechanistic studies to understand TREM2's dual protective and pathological roles before advancing complex multi-stage or metabolic reprogramming approaches."
