Comparing 2 hypotheses side-by-side
This hypothesis proposes that TREM2 signaling in microglia directly regulates astrocytic calcium dynamics to control glymphatic tau clearance efficiency. The mechanism begins with TREM2/DAP12 signaling in perivascular microglia, where functional TREM2 receptors detect tau oligomers and activate the Syk-PI3K cascade. Critically, activated microglia release ATP and complement factors that bind to P2Y1 and C3aR receptors on adjacent astrocyte endfeet, triggering robust calcium oscillations through
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. The highest
