Abstract

The present invention relates to compositions and methods for restoring hearing loss. In particular aspects, the invention relates to the administration of compositions that encode an inflammatory response control element. The compositions are prepared and administered in such a manner that the inflammatory response control element coding sequence is expressed in the subject to which the composition is administered. The compositions include expression systems, delivery systems, and certain inflammatory response control genes.

Claims

1. A method of treating or ameliorating hearing loss, said method comprising administering a composition comprising nucleic acid that reduces inflammation,

wherein said nucleic acid comprises a sequence encoding IL-10.

2. The method of claim 1, wherein said nucleic acid comprises one or more selected from the group consisting of a polynucleotide, DNA, RNA.

3. The method of claim 1, wherein said polynucleotide is a plasmid comprising a promoter/enhancer transcriptionally linked to said sequence encoding an inflammatory response control polypeptide.

4. The method of claim 1, wherein said nucleic acid is administered with a transfection facilitating material.

5. The method of claim 1, wherein said administering comprises one or more methods selected from the group consisting of intravenous injection, intramuscular injection, intraperitoneal injection, subcutaneous injection, inhalation, and gene gun.

6. The method of claim 1, wherein said hearing loss is caused by an autoimmune disease.

7. The method of claim 6, wherein said autoimmune disease is an autoimmune inner ear disease.

8. The method of claim 7, wherein said autoimmune inner ear disease is Menier'"'"'s disease.

9. The method of claim 1, wherein said administering increases expression of a gene that decreases inflammation.

10. The method of claim 1, wherein said nucleic acid further comprises one or more sequences selected from SEQ ID NOs:

1-15.
