摘要:
Sterically stabilized cationic liposomes (SSCL) encapsulating a K type oligodeoxynucleotide (ODN) including a CpG motif are disclosed. These SSCL encapuslating a K type ODN can be used to effectively deliver the ODN to a cell. A novel method is also disclosed for producing the SSCL encapsulating the K type ODN. Administration of the SSCL encapsulating a K type ODN and a chemotherapeutic agent, such as a chimeric molecule comprising a targeting molecule selected from the group consisting of an IL-13, and an anti-IL-13 receptor antibody; and an effector molecule selected from the group consisting of a Pseudomonas exotoxin, a Diphtheria toxin, and a radionuclide, can be used to dramatically reduce the growth of solid tumors.
摘要:
The present invention provides a method and compositions for specifically delivering an effector molecule to a tumor cell. The method involves providing a chimeric molecule comprising an effector molecule attached to a targeting molecule that specifically binds an IL-13 receptor and contacting a tumor cell with the chimeric molecule in the presence of an interleukin-4 receptor (IL-4R) blocker.
摘要:
This invention provides chimeric molecules useful for killing tumor cells bearing IL13 receptor(s) (IL-13R). The molecules comprise a cytotoxic molecule attached to a targeting molecule that specifically binds an IL-13 receptor. Preferred targeting molecules include IL-13 and anti-IL-13R antibodies.
摘要:
The present invention provides for circularly permuted ligands which possess specificity and binding affinity comparable to or greater than the specificity and binding affinity of the original (unpermuted) ligand. The invention further provides for novel chimeric molecules comprising a circularly permuted ligand joined to one or more molecules of interest.

摘要:
The invention provides uses and methods for alleviating respiratory tract symptoms of allergy, asthma, and of viral, bacterial, fungal and parasitic infections by shifting inappropriate TH2 responses to TH1 responses by administering IL-13 receptor-targeted immunotoxins to the respiratory tract.
摘要:
The present invention provides a method and compositions for specifically delivering an effector molecule to a tumor cell bearing an IL-13 receptor. The method involves providing a chimeric molecule that comprises an effector molecule attached to a circularly permuted IL-13 (“cpIL-13”) that specifically binds an IL-13 receptor and contacting the tumor cell with the chimeric molecule. The compositions include chimeric molecules comprising effector molecules such as modified Pseudomonas exotoxin attached to a cpIL-13. The invention further provides vectors encoding the chimeric molecules.
