Methods of treating diseases associated with PPARγ
View Patent ↗The invention relates to methods for modulating PPAR-γ activity using relaxin or agonists thereof. The result is wide range of new therapeutic regimens for treating, inhibiting the development of, or otherwise dealing with, a multitude of illnesses and conditions, including small vessel disorders of the brain and those associated with increased blood-brain barrier permeability, cognitive disorders such as Alzheimer's disease, vascular dementia, epilepsy, stroke, CADASIL and migraine.
1. A method for treating a small vessel disease of the brain, comprising
identifying a subject as having a small vessel disease of the brain and chronically administering to the subject having the small vessel disease of the brain a relaxin or agonist thereof, wherein the subject is not otherwise in need of treatment with relaxin or agonist thereof in an effective amount to promote outward remodeling of the small vessels of the brain, wherein the small vessel disease of the brain is due to hypertension and wherein the relaxin or agonist thereof crosses the blood brain barrier.
2. The method of claim 1 , wherein the subject has CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy).
3. The method of claim 1 , wherein the relaxin or agonist thereof is recombinant human relaxin.
4. The method of claim 1 , further comprising administering to the subject a PPAR-γ agonist.
5. The method of claim 4 , wherein the PPAR-γ agonist is a thiazolidinedione.
6. The method of claim 1 , wherein the relaxin or agonist thereof is administered to the subject orally.
7. The method of claim 1 , wherein the relaxin or agonist thereof is administered to the subject transdermally.
8. The method of claim 1 , wherein the relaxin or agonist thereof is administered to the subject subcutaneously.
9. The method of claim 1 , wherein the relaxin or agonist thereof is administered to the subject in a sustained release formulation.
10. The method of claim 1 , wherein the relaxin is administered to the subject at a predetermined rate so as to maintain a serum concentration of at least about 1 ng/ml.
11. A method for treating a small vessel disease of the brain, comprising
identifying a subject as having small vessel disease of the brain and administering to the subject a relaxin or agonist thereof, wherein the small vessel disease of the brain is due to hypertension and wherein the relaxin or agonist thereof crosses the blood brain barrier.
12. A method for treating a disease of the brain, comprising
identifying a subject as having a small vessel disease of the brain due to hypertension and administering to the subject a relaxin or agonist thereof, wherein the relaxin or agonist thereof has a neuroprotective effect in the brain.
