This hypothesis combines targeted miR-33 inhibition with complement-mediated brain delivery to overcome APOE4's inherent lipidation deficiency in Alzheimer's disease. The strategy involves conjugating miR-33 antisense oligonucleotides (ASOs) to C1q complement protein to achieve receptor-mediated transcytosis across the blood-brain barrier. C1q naturally crosses the BBB via complement receptor-mediated endocytosis and accumulates in microglial cells, the primary brain cell type expressing ABCA1.
This hypothesis proposes using C1q protein as a brain-penetrant delivery vehicle for miR-33 antisense oligonucleotides (ASOs) to achieve therapeutic hyper-lipidation of APOE4 particles in Alzheimer's disease. The strategy exploits C1q's natural ability to cross the blood-brain barrier through receptor-mediated transcytosis at brain endothelial cells, which express complement receptors including C1qR and gC1qR. By conjugating miR-33 ASOs to C1q, the therapeutic payload would be selectively delive
