From Analysis:
VEGF Family GWAS Signals and Cerebrovascular-Neuronal Coupling in AD Hippocampus
How do VEGF family gene variants identified by single-cell GWAS analysis alter cerebrovascular-neuronal coupling specifically in the AD hippocampus, and can spatial transcriptomics resolve whether VEGF-driven vascular dysfunction precedes or follows amyloid deposition in vulnerable hippocampal subfields?
The debate supports treating this as a validation program before ranking it as a therapy. Perturbation should move a proximal molecular phenotype, then a disease-relevant phenotype, in that order.

Source basis: Association of ten VEGF family genes with Alzheimer's disease endophenotypes at single cell level (Alzheimer's & Dementia, 2025, DOI 10.1002/alz.14419). The stored gap context says: VEGF family single-cell GWAS analysis identified associations with AD endophenotypes; the causal mechanism linking VEGF variants to hippocampal vascular-neuronal coupling was highlighted as requiring investigation.
Primary hypothesis: VEGF-family genet
Skeptic critique for analysis a7f528aa-20c4-409d-a8c3-e2662850e63d: VEGF Family GWAS Signals and Cerebrovascular-Neuronal Coupling in AD Hippocampus
The source paper motivates the gap, but motivation is not causal evidence. The main threat is that the observed association in Association of ten VEGF family genes with Alzheimer's disease endophenotypes at single cell level could be downstream of disease stage, tissue composition, survival bias, or batch structure. The specific concern here is: vascular changes may be secondary to neurodegeneration rather than upstream drivers.

The practical path is feasible but should be staged. Stage 1 should reanalyze or collect human data at the needed resolution, preserving pathology, sex/genotype, region, and disease-stage covariates when relevant. Stage 2 should test VEGF-family genetic control of vascular-neuronal coupling in vulnerable hippocampal regions in a model where the proximal readout can be measured before overt toxicity. Stage 3 should connect the readout to a
