## Molecular Mechanism and Rationale The apolipoprotein E4 (APOE4) allele represents the strongest genetic risk factor for late-onset Alzheimer's disease, conferring a 3-fold increased risk in heterozygotes and up to 15-fold increased risk in homozygotes. However, the mechanistic basis for APOE4's pathogenicity has remained enigmatic, particularly given that complete APOE deficiency does not recapitulate Alzheimer's pathology. Recent single-cell RNA sequencing and spatial transcriptomics studie
