# Prime Editing Precision Correction of APOE4 to APOE3 in Microglia
## Molecular Mechanism and Rationale
The apolipoprotein E4 (APOE4) variant represents the strongest genetic risk factor for late-onset Alzheimer's disease, conferring a 3-fold increased risk in heterozygotes and 12-fold risk in homozygotes compared to the protective APOE3 allele. The pathogenic C130R substitution in APOE4 fundamentally alters protein structure, reducing lipid binding affinity and promoting aberrant protein agg
## Multiplexed Base Editing for Simultaneous Neuroprotective Gene Activation
### Mechanistic Hypothesis Overview
The "Multiplexed Base Editing for Simultaneous Neuroprotective Gene Activation" hypothesis proposes that base editing technology — which enables precise single-nucleotide changes without double-strand DNA breaks — can be used to simultaneously activate multiple neuroprotective gene programs in neurons and glia affected in Alzheimer's disease. The central claim is that rather than co
