Description

The debate aimed to identify mechanisms of differential cellular vulnerability in Alzheimer’s disease but failed to generate any mechanistic hypotheses. Understanding these mechanisms is essential for developing targeted neuroprotective strategies.

Resolution criteria

Resolution requires: (1) spatial transcriptomics (MERFISH or 10x Visium) of AD brains (n>=15) mapping cell-type-specific vulnerability signatures (CUX2+, RORB+ excitatory neurons) with spatial coordinates and pixel-level quantitative cell death markers; (2) functional perturbation experiments (CRISPRi/CRISPRa of candidate vulnerability genes) in iPSC-derived neurons showing >=50% difference in AD pathology susceptibility between vulnerable and resistant subtypes; (3) proteomic or phosphoproteomic comparison of isolated vulnerable vs resistant neuronal populations identifying >=3 discriminating pathway hubs. Transcriptomic correlation without functional validation is insufficient.
