Methods and compositions for treating neuropathies
View Patent ↗Methods of treating or preventing axonal degradation in neuropathic diseases in mammals are disclosed. The methods can comprise administering to the mammal an effective amount of an agent that acts by increasing sirtuin activity in diseased and/or injured neurons. The methods can also comprise administering to the mammal an effective amount of an agent that acts by increasing NAD activity in diseased and/or injured neurons. Also disclosed are methods of screening agents for treating a neuropathies and recombinant vectors for treating or preventing neuropathies.
1. A method of treating an axonopathy in a mammal in need thereof, the method comprising administering to the mammal an agent that acts by increasing sirtuin activity in diseased and/or injured neurons and supporting cells in an amount effective to decrease axonal degeneration.
2. A method according to claim 1 , wherein the agent acts by increasing SIRT1 activity.
3. A method according to claim 1 , wherein the agent is NAD, NADH, an intermediate of a de novo pathway for synthesizing NAD, an intermediate of a NAD salvage pathway, an intermediate of a nicotinamide riboside kinase pathway or a combination thereof.
4. A method according to claim 1 , wherein the agent is NAD, nicotinamide mononucleotide, nicotinic acid mononucleotide or nicotinamide riboside.
5. A method according to claim 1 , wherein the mammal is a human.
6. A method in accordance with claim 4 wherein the agent is nicotinamide riboside.
