Claims
- 1. A method for treating injury or degeneration of cells of the inner ear comprising administering to a subject a therapeutically effective amount of a neurturin protein product comprising an amino acid sequence set forth in SEQ ID NOs: 1, 2, 3, 4 or 5 wherein said neurturin protein product promotes the survival or function of cochlear hair cells and auditory neurons of the inner ear.
- 2. The method of claim 1, wherein the hearing loss is associated with injury or degeneration of neuroepithelial hair cells in the inner ear.
- 3. The method of claim 1, wherein the hearing loss is associated with injury or degeneration of spiral ganglion neurons.
- 4. The method of claim 1, wherein said auditory neurons are spiral ganglion neurons.
- 5. The method of claim 1, wherein the neurturin protein product has the amino acid sequence set forth in SEQ ID NO:1.
- 6. The method of claim 1, wherein the neurturin protein product has the amino acid sequence set forth in SEQ ID NOs:3 and 4.
- 7. The method of claim 1, wherein the neurturin protein product is (Met.sup.-1)neurturin.
- 8. The method of claim 1, wherein the neurturin protein product is administered at a dose of about 1 .mu.g/kg/day to about 100 mg/kg/day.
- 9. The method of claim 1, wherein the neurturin protein product is administered by cell therapy or gene therapy means wherein cells have been modified to produce and secrete the neurturin protein product.
- 10. The method of claim 8, wherein the cells have been modified ex vivo.
- 11. The method of claim 8, wherein the cells have been modified in vivo.
