Gene therapy for amyotrophic lateral sclerosis and other spinal cord disorders
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 a transgene product is delivered to a subject's spinal cord by administering a recombinant viral vector containing the transgene to the spinal cord. The viral vector delivers the transgene which expresses the encoded recombinant viral gene product. The viral gene product comprises HIF1-alpha. Also provided are compositions for delivery of a transgene product to a subject's spinal cord.
1. A recombinant gene delivery vector, comprising a recombinant AAV vector encoding a DNA binding domain of hypoxia-inducible factor 1-alpha (HIF 1-alpha) fused to a herpes simplex virus virion protein 16 (HSV VP 16) transcriptional activation domain, wherein the recombinant AAV vector comprises inverted terminal repeats of AAV-2 and an AAV-7 capsid or inverted terminal repeats of AAV-2 and an AAV-8 capsid, wherein the recombinant AAV vector is for treating patients with a motor neuron disorder, wherein the DNA binding domain of HIF 1-alpha fused to the HSV VP 16 transcriptional activation domain is encoded by the nucleotide sequence as shown in SEQ ID NO:1.
2. The vector of claim 1 , wherein the recombinant AAV vector comprises inverted terminal repeats of AAV-2 and an AAV-7 capsid.
3. The vector of claim 1 , wherein the recombinant AAV vector comprises inverted terminal repeats of AAV-2 and an AAV-8 capsid.
