Mechanistic description

The debate supports carrying forward microglial priming as a partially upstream causal node rather than a pure disease-stage correlate only if a proximal endpoint changes before the late outcome. The decisive validation path is: triangulate cell-type-specific MR, scVelo trajectory direction, and longitudinal CSF cytokine Granger causality with disease-specific sensitivity analyses.

Mechanism / pathway

  1. TREM2
  2. neurodegeneration

Evidence for (1)

  • Analytic arms: cell-type-specific MR, scVelo trajectory, longitudinal CSF Granger causality. Exposure genes: TREM2, CX3CR1, C1QA, C1QB, C1QC. Diseases: AD, PD, ALS, MS.

    SDA-2026-04-28-microglial-priming-causal-nd

Evidence against (1)

  • microglial activation can be both cause and response; weak eQTL instruments, cell-state drift, and disease-stage confounding could inflate upstream causal estimates
