Abstract

Abstract Methods of preventing neural tissue damage caused by excitotoxicity due to increased release of excitatory amino acids by increasing extracellular concentrations of adenosine in and around the neural tissue are provided. These methods are especially useful in treating neurodegenerative diseases such as Parkinson's Disease, Alzheimer's Disease, Amyotrophic Lateral Sclerosis or Huntington's Disease.

Claims Analysis

Total Claims: 30
Claim 1
Independent Claim 47 words
A method of preventing neural tissue damage caused by excitotoxicity due to increased release of excitatory amino acids in an affected animal wherein said excitotoxicity is caused by or causes a neurodegenerative condition which comprises increasing the extracellular concentration of adenosine in and about said neural tissue.
Claim 2
Independent Claim 47 words
A method of preventing neural tissue damage caused by excitotoxicity due to increased release of excitatory amino acids in an affected animal wherein said excitotoxicity is caused by or causes a neurodegenerative condition which comprises increasing the extracellular concentration of adenosine in and about said neural tissue.
Claim 3
Dependent Claim 37 words
A method according to claim 1 wherein said adenosine concentrations are increased by administering to said individual a therapeutically effective amount of an agent which increases the extracellular concentration of adenosine in and about said neural tissue.
Claim 4
Dependent Claim 22 words
A method according to claim 2 wherein said agent comprises an adenosine regulating agent, an adenosine agonist, or an adenosine transport inhibitor.
Claim 5
Dependent Claim 13 words
A method according to claim 3 wherein said agent comprises an adenosine agonist.
Claim 6
Dependent Claim 14 words
A method according to claim 3 wherein said agent comprises an adenosine regulating agent.
Claim 7
Dependent Claim 15 words
A method according to claim 2 wherein said neural tissue is brain or spinal chord.
Claim 8
Dependent Claim 16 words
A method according to claim 6 wherein said excitotoxicity is caused by or causes brain trauma.
Claim 9
Dependent Claim 21 words
A method according to claim 2 wherein said neurodegenerative condition is Parkinson's Disease, Alzheimer's Disease, Amyotrophic Lateral Sclerosis or Huntington's Disease.
Claim 10
Dependent Claim 22 words
A method according to claim 8 wherein said agent comprises an adenosine regulating agent, an adenosine agonist, or an adenosine transport inhibitor.
Claim 11
Independent Claim 28 words
A method of decreasing neural tissue damage associated with a neurodegenerative disease in an affected individual which comprises increasing the extracellular concentration of adenosine in said neural tissue.
Claim 12
Independent Claim 28 words
A method of decreasing neural tissue damage associated with a neurodegenerative disease in an affected individual which comprises increasing the extracellular concentration of adenosine in said neural tissue.
Claim 13
Dependent Claim 26 words
A method according to claim 10 wherein said adenosine concentration are increased by administering to said individual a therapeutically effective amount of an adenosine-concentration increasing agent.
Claim 14
Dependent Claim 25 words
A method according to claim 11 wherein said adenosine consentration increasing agent comprises an adenosine regulating agent, an adenosine agonist, or an adenosine transport inhibitor.
Claim 15
Dependent Claim 17 words
A method according to claim 12 wherein said adenosine concentration increasing agent comprises an adenosine regulating agent.
Claim 16
Dependent Claim 20 words
A method according to claim 13 wherein said adenosine regulating agent comprises a purine nucleoside or analog or prodrug thereof.
Claim 17
Dependent Claim 21 words
A method according to claim 14 wherein said adenosine regulating agent comprises AICA riboside or an AICA riboside prodrug or analog.
Claim 18
Dependent Claim 16 words
