Delivery of ricin toxin a-chain by peptide-targeted mesoporous silica nanoparticle-supported lipid bilayers. Academic Article uri icon

abstract

  • Mesoporous silica nanoparticle-supported lipid bilayers, or "protocells", exhibit a high loading capacity, enhanced colloidal stability, and peptide-directed, cell-specific uptake, making them especially well-suited for targeted delivery of protein toxins to cancer. Protocells loaded with ricin toxin A-chain (RTA) and targeted to hepatocellular carcinoma cause complete cell death at 30 pM of RTA without affecting the viability of control hepatocytes.Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
