Bioinspired artificial nanodecoys for hepatitis B virus


Researchers from Xiamen University present a facile route for fabricating a new class of nanomimics that overexpress hepatitis B virus (HBV) receptor by a natural biosynthetic procedure against HBV infection. A nine-transmembrane HBV-specific receptor, human sodium taurocholate co-transporting polypeptide (hNTCP), was engineered to naturally immobilize it onto the cellular surface and subsequently trigger the budding of hNTCP-anchoring membrane vesicles (hNTCP-MVs) that favor the HBV virion. hNTCP-MVs could rapidly block HBV infection in cell models. Furthermore, hNTCP-MVs treatment could effectively prevent viral infection, spreading, and replication in a human-liver-chimeric mouse model of HBV infection. These findings demonstrate the receptor-mediated antiviral effect of hNTCP-MVs to trick HBV and offer novel opportunities for further development of antiviral strategies in nanomedicine.
