Intravenous administration of blood–brain barrier-crossing conjugates facilitate biomacromolecule transport into central nervous system
摘要
Delivery of biomacromolecules to the central nervous system (CNS) remains challenging because of the restrictive nature of the blood–brain barrier (BBB). We developed a BBB-crossing conjugate (BCC) system that facilitates delivery into the CNS through γ-secretase-mediated transcytosis. Intravenous administration of a BCC10–oligonucleotide conjugate demonstrated effective transportation of the oligonucleotide across the BBB and gene silencing in wild-type mice, human brain tissues and an amyotrophic lateral sclerosis mouse model.
