Abstract: Provided herein are compositions, kits, methods and systems related to administering a structure that crosses the blood brain barrier (BBB) along with a monosaccharide, either simultaneously or consecutively. The structure may be, for example an antibody or fusion antibody that binds to an insulin receptor.

Abstract: A humanized murine antibody is provided that binds to the human insulin receptor (HIR). The humanized murine antibody is suitable for use as a Trojan horse to deliver pharmaceutical agents to human organs and tissue that express the HIR. The humanized murine antibody is especially well suited for delivering neuropharmaceutical agents from the blood stream to the brain across the blood brain barrier (BBB). The humanized murine antibody may be genetically fused to the pharmaceutical agent or it may be linked to the pharmaceutical agent using an avidin-biotin conjugation system.

Abstract: The invention provides compositions, methods, and kits for increasing transport of agents across the blood brain barrier while allowing their activity once across the barrier to remain substantially intact. The agents are transported across the blood brain barrier via one or more endogenous receptor-mediated transport systems. In some embodiments the agents are therapeutic, diagnostic, or research agents.

Abstract: Receptor-specific nanocontainers are used to deliver a gene that encodes short hairpin RNA to cells having a given receptor. Once inside the cell, the gene expresses short hairpin RNA that includes a nucleotide sequence that is antisense to at least a portion of an oncogene, such as human epidermal growth factor receptor (EGFR) mRNA, or other disease causing nucleotide sequence. The short hairpin RNA is converted, in the cellular cytoplasm, into short RNA duplexes that are effective in deactivating (knocking down) the oncogenic or disease causing gene.
