Abstract

This disclosure provides methods and compositions for treating disorders or injuries that affect motor function and control in a subject. In one aspect, the invention provides a method to deliver a transgene to a subject's spinal cord by administering a recombinant neurotropic viral vector containing the transgene. The viral vector delivers the transgene to a region of the deep cerebellar nuclei region of the brain. Also provided are compositions and methods to deliver a transgene to a subject's spinal cord by administering a recombinant neurotropic viral vector containing the transgene to the motor cortex region of the subject's brain.

First claim

The invention claimed is:

1. A method to treat amyotrophic lateral sclerosis (ALS) in a subject, comprising administering a recombinant neurotropic viral vector comprising a therapeutic transgene to at least one region of the deep cerebellar nuclei region of the brain under conditions that favor expression of the transgene in a motor neuron distal to the site of administration, wherein the transgene product is delivered in a therapeutically effective amount to at least one subdivision of the spinal cord and/or at least one division of the brainstem, wherein said neurotropic viral vector is an adeno-associated viral vector comprising an AAV1 serotype capsid, and wherein the therapeutic transgene is insulin growth factor-1 (IGF-1).

2. The method of claim 1 , wherein said region of the deep cerebellar nuclei region of the brain is selected from the group consisting of the medial region, interposed region and the lateral region.

3. The method of claim 1 , wherein said delivery is bilateral.

4. The method of claim 1 , wherein said spinal cord subdivision is selected from the group consisting of the cervical subdivision, the thoracic subdivision, the lumbar subdivision, and the sacral subdivision.

5. The method of claim 1 , wherein said transgene product is delivered to all subdivisions of the spinal cord.

6. The method of claim 1 , wherein the administration comprises multiple administrations.

7. The method of claim 1 , wherein said subject is a human patient.

8. The method of claim 1 , wherein said transgene expresses a therapeutic amount of insulin growth factor-1 (IGF-1).

9. The method of claim 1 , wherein the AAV vector comprises an AAV2 ITR or an AAV1 ITR.

10. The method of claim 6 , wherein at least one of the multiple administrations is bilateral.
