Method of inducing neuronal production in the caudate nucleus and putamen
The present invention relates to methods of inducing neuronal production in the brain, recruiting neurons to the brain, and treating a neurodegenerative condition by providing a nucleic acid construct encoding a neurotrophic factor, and injecting the nucleic acid construct intraventricularly into a subject's brain.
1. A method of inducing addition of medium spiny neurons in post-natal and adult brain comprising:
providing a neurotrophic factor selected from the group consisting of NT-4 and brain-derived neurotrophic factor;
providing an inhibitor of a bone morphogenetic protein which is not in the form of a nucleic acid; and
administering the neurotrophic factor and the inhibitor of the bone morphogenetic protein to a subject's lateral ventricles to induce addition of medium spiny neurons in any one or all of the caudate nucleus and the putamen of the subject.
2. The method according to claim 1 , wherein the neurotrophic factor is NT-4.
3. The method according to claim 1 , wherein the neurotrophic factor is brain-derived neurotrophic factor.
4. The method according to claim 1 , wherein the inhibitor of the bone morphogenetic protein is noggin.
5. A method of inducing addition of medium spiny neurons in a subject having Huntington's Disease comprising:
providing a neurotrophic factor selected from the group consisting of NT-4 and brain-derived neurotrophic factor;
providing an inhibitor of a bone morphogenetic protein which is not in the form of a nucleic acid; and
administering the neurotrophic factor and the inhibitor of the bone morphogenetic protein to the subject's lateral ventricles to induce addition of medium spiny neurons in any one or all of the caudate nucleus and the putamen of the subject.
6. The method according to claim 5 , wherein the neurotrophic factor is NT-4.
7. The method according to claim 5 , wherein the neurotrophic factor is brain-derived neurotrophic factor.
8. The method according to claim 5 , wherein the inhibitor of the bone morphogenetic protein is noggin.
9. The method according to claim 5 , wherein Huntington's Disease progression is delayed.
10. A method of treating Huntington's Disease comprising:
providing a neurotrophic factor selected from the group consisting of NT-4 and brain-derived neurotrophic factor;
providing an inhibitor of a bone morphogenetic protein which is not in the form of a nucleic acid; and
administering the neurotrophic factor and the inhibitor of the bone morphogenetic protein inhibitor to a subject's lateral ventricles to induce addition of medium spiny neurons in any one or all of the caudate nucleus and the putamen of the subject to treat Huntington's Disease.
11. The method according to claim 10 , wherein the neurotrophic factor is NT-4.
12. The method according to claim 10 , wherein the neurotrophic factor is brain-derived neurotrophic factor.
13. The method according to claim 10 , wherein the inhibitor of the bone morphogenetic protein is noggin.
14. The method according to claim 10 , wherein Huntington's Disease progression is delayed.
15. The method according to claim 1 , wherein the inhibitor of the bone morphogenetic protein is a protein.
16. The method according to claim 5 , wherein the inhibitor of the bone morphogenetic protein is a protein.
17. The method according to claim 10 , wherein the inhibitor of the bone morphogenetic protein is a protein.
