The products of biotechnology, recombinant proteins, monoclonal antibodies, antisense, RNA interference, or non-viral gene transfer, cannot be developed as pharmaceuticals for the brain, unless these molecules are re-formulated to enable transport across the blood-brain barrier (BBB). Large molecule drugs, and plasmid DNA, can be delivered across the BBB with receptor-specific molecular Trojan horses. Trojan horse BBB delivery systems, coupled with one of 3 different technology platforms (fusion proteins, avidin-biotin, or Trojan horse liposomes), can enable the BBB transport of virtually any large molecule drug or plasmid DNA.
生物技术产品,如重组蛋白、单克隆抗体、反义核酸、RNA干扰剂或非病毒基因转移载体,除非重新配制以使其能够穿越血脑屏障(BBB),否则无法开发成脑部用药。大分子药物和质粒DNA可通过受体特异性分子“特洛伊木马”穿越血脑屏障。“特洛伊木马”血脑屏障递送系统与三种不同技术平台(融合蛋白、抗生物素蛋白-生物素或“特洛伊木马”脂质体)之一相结合,几乎可以实现任何大分子药物或质粒DNA的血脑屏障转运。
