Comparing 2 hypotheses side-by-side
APOE (Apolipoprotein E) shows significant upregulation (log2FC = +1.8) in the SEA-AD dataset, with expression patterns varying dramatically across astrocyte and microglial subtypes in the middle temporal gyrus. The APOE4 allele is the strongest genetic risk factor for late-onset Alzheimer's disease, carried by approximately 25% of the population and present in over 60% of AD patients. The SEA-AD single-cell data enables dissecting APOE isoform-specific effects at unprecedented cellular resolutio
## Molecular Mechanism and Rationale APOE4-Specific Lipidation Enhancement Therapy targets the fundamental molecular deficiency that distinguishes the APOE4 isoform from its neuroprotective counterparts, APOE2 and APOE3. The apolipoprotein E (APOE) protein exists in three major human isoforms, differing by only two amino acids: APOE2 (Cys112, Cys158), APOE3 (Cys112, Arg158), and APOE4 (Arg112, Arg158). These seemingly minor variations have profound structural and functional consequences, partic
