This hypothesis proposes that age-related TREM2 signaling dysfunction drives microglia into a senescent state that fundamentally rewires astrocyte-microglia communication networks, creating a pathological feedback loop in neurodegeneration. Under normal conditions, TREM2/TYROBP signaling maintains microglial homeostasis and supports neuroprotective astrocyte-microglia cross-talk through regulated release of IL-33, lactate, and ATP. However, during aging, accumulated DNA damage and metabolic stre
Bayesian fine-mapping of the top 25 AD GWAS loci will identify credible sets significantly enriched for variants disrupting microglia-specific regulatory elements, reflecting microglial dysfunction as a central AD pathogenic mechanism. Credible sets at loci with known effector genes (APOE, TREM2, PLCG2) will be smaller (<10 variants) due to stronger functional constraints, while novel loci will have larger sets requiring integration with epigenomic data to prioritize causal variants.
