Abstract

The present invention provides a novel CXCL12-α 2 locked dimer polypeptide, pharmaceutical compositions thereof, and methods of using said dimer in the treatment of cancer, inflammatory disorders, autoimmune disease, and HIV/AIDS.

Claims (7)

1. A method of treating blood cancer in a subject comprising administering to the subject a therapeutically effective amount of a composition comprising a CXCL12α 2 locked dimer polypeptide, wherein the blood cancer cells express CXCR4.

2. The method of claim 1 wherein the subject is human.

3. A method of treating leukemia in a subject comprising administering to the subject a therapeutically effective amount of a composition comprising a CXCL12α 2 locked dimer polypeptide, wherein the leukemia cells express CXCR4.

4. A method of inhibiting migration of cancer cells in a subject comprising administering to the subject a therapeutically effective amount of a composition comprising a CXCL12α 2 locked dimer polypeptide, wherein the cancer cells express CXCR4.

5. The method of claim 4 wherein the cancer cells are selected from the group consisting of leukemia, lymphoma and myeloma.

6. A method of inhibiting migration of leukemia cells in a subject comprising administering to the subject a therapeutically effective amount of a composition comprising a CXCL12α 2 locked dimer polypeptide, wherein the leukemia cells express CXCR4.

7. The method of claim 1 wherein the blood cancer is selected from the group consisting of leukemia, lymphoma and myeloma.
