## Molecular Mechanism and Rationale
The HSP70 chaperone system operates as a protein disaggregation machine through an ATP-dependent cycle involving multiple specialized co-factors. HSPA1A (inducible HSP70) and HSPA8 (constitutive HSC70) work in concert with HSP40 co-chaperones (DNAJA1, DNAJB1) and the nucleotide exchange factor HSP110 (HSPH1) to form a trimeric disaggregase complex capable of extracting individual polypeptide chains from amorphous aggregates and amyloid fibrils through a thre
**Background and Rationale**
The apolipoprotein E epsilon 4 allele (APOE4) represents the strongest genetic risk factor for late-onset Alzheimer's disease, increasing risk 3-fold in heterozygotes and 8-15-fold in homozygotes. While traditional research has focused on APOE4's effects on amyloid-β clearance and lipid transport, emerging evidence suggests that the structural instability of APOE4 itself creates a fundamental proteostasis crisis that drives neurodegeneration through multiple converg
