Abstract
Abstract The invention relates to a method of delivering exogenous DNA to a target cell of the mammalian central nervous system using an adeno-associated virus (AAV)-derived vector. Also included in the invention are the AAV-derived vectors containing exogenous DNA which encodes a protein or proteins which treat nervous system disease, and a method of treating such disease.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
108 words
A method for ameliorating a symptom of a central nervous system disorder in a mammal, the method comprising, direct administration of an adeno-associated virus-derived vector to a target cell in the brain of the mammal, said vector comprising a DNA sequence, wherein said DNA sequence is exogenous to an adeno-associated virus and comprises a sequence encoding a therapeutic protein in operable linkage with a promoter sequence, wherein said adeno-associated virus-derived vector is free of both wild-type and helper virus, and wherein the exogenous DNA sequence is expressed in the target cell for greater than 3 months such that the symptom of the central nervous system disorder is ameliorated.
Claim 2
Independent Claim
108 words
A method for ameliorating a symptom of a central nervous system disorder in a mammal, the method comprising, direct administration of an adeno-associated virus-derived vector to a target cell in the brain of the mammal, said vector comprising a DNA sequence, wherein said DNA sequence is exogenous to an adeno-associated virus and comprises a sequence encoding a therapeutic protein in operable linkage with a promoter sequence, wherein said adeno-associated virus-derived vector is free of both wild-type and helper virus, and wherein the exogenous DNA sequence is expressed in the target cell for greater than 3 months such that the symptom of the central nervous system disorder is ameliorated.
Claim 3
Dependent Claim
23 words
The method of claim 1 , wherein the exogenous DNA sequence is expressed in said target cell either constitutively or under regulatable conditions.
Claim 4
Dependent Claim
27 words
The method of claim 2 , wherein the exogenous DNA sequence encodes a protein selected from the group consisting of tyrosine hydroxylase and aromatic amino acid decarboxylase.
Claim 5
Dependent Claim
20 words
The method of claim 2 , wherein the exogenous DNA sequence encodes a specific neurotrophic factor for mesencephalic dopaminergic neurons.
Claim 6
Dependent Claim
35 words
The method of claim 4 , wherein the specific neurotrophic factor for mesencephalic dopaminergic neurons is selected from the group consisting of glial-derived neurotrophic factor (GDNF), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF).
Claim 7
Dependent Claim
19 words
The method of claim 1 , wherein all adeno-associated viral genes of the vector have been deleted or inactivated.
Claim 8
Dependent Claim
18 words
The method of claim 1 , wherein the vector comprises only the inverted terminal repeats of adeno-associated virus.
Claim 9
Dependent Claim
16 words
The method of claim 1 , wherein said promoter sequence is a central nervous system-specific promoter.
Claim 10
Dependent Claim
14 words
The method of claim 8 , wherein said promoter sequence is a neuron-specific promoter.
Claim 11
Dependent Claim
14 words
The method of claim 8 , wherein said promoter sequence is a glia-specific promoter.
Claim 12
Dependent Claim
29 words
The method of claim 1 , wherein the target cell is in a region of the brain selected from the group consisting of cerebellum, striatum, hippocampus, and substantia nigra.
Claim 13
Dependent Claim
20 words
The method of claim 1 , wherein the target cell is a primate target cell or a rat target cell.
Claim 14
Dependent Claim
16 words
The method of claim 12 , wherein the primate target cell is a human target cell.
Claim 15
Dependent Claim
13 words
The method of claim 1 , wherein direct administration is by stereotaxic injection.
Claim 16
Dependent Claim
39 words
An adeno-associated virus-derived vector comprising only the replication and packaging signals of adeno-associated virus, and further comprising a DNA molecule comprising a DNA sequence encoding tyrosine hydroxylase, a DNA sequence encoding aromatic amino acid decarboxylase, and a promoter sequence.
Claim 17
Dependent Claim
39 words
An adeno-associated virus-derived vector comprising only the replication and packaging signals of adeno-associated virus, and further comprising a DNA molecule comprising a DNA sequence encoding tyrosine hydroxylase, a DNA sequence encoding aromatic amino acid decarboxylase, and a promoter sequence.
