This hypothesis proposes that C1q complement protein forms stable complexes with alectinib through electrostatic and hydrophobic interactions, creating a targeted delivery system that exploits microglial C1q receptor (C1qR) recognition mechanisms. Upon systemic administration, C1q-alectinib complexes cross the blood-brain barrier through established C1q transport pathways, likely involving megalin-mediated transcytosis at brain capillary endothelium. Once in the CNS parenchyma, activated microgl
**Background and Rationale**
Alzheimer's disease (AD) pathogenesis is intimately linked to apolipoprotein E (APOE) isoform-dependent differences in amyloid-beta (Aβ) clearance and lipid metabolism. The APOE4 allele, present in approximately 25% of the population and 65% of AD patients, confers the highest genetic risk for late-onset AD. Unlike APOE2 and APOE3, APOE4 exhibits significantly reduced lipidation capacity and impaired Aβ clearance efficiency. This stems from structural differences in
