Method of using abscisic acid to treat diseases and disorders
Methods and compositions for treating inflammatory bowel disease, gastrointestinal inflammation and maintaining normal gut health are described. These methods of the invention involve the administration of abscisic acid in amounts sufficient to alter the expression or activity of PPAR gamma in a cell. Also described are methods for suppressing the expression of cellular adhesion molecules in the gut and methods for increasing CTLA-4 expression on CD4+ T cells through administration of abscisic acid.
1. A method for treating inflammatory bowel disease in a mammal, the method comprising administering to the mammal a composition comprising:
a substantially pure preparation of one or more compounds selected from: abscisic acid (ABA) in its free acid form and pharmaceutically suitable salts thereof, in amounts that are sufficient to alter the expression or activity of PPAR γ in a cell of the mammal.
2. The method of claim 1 , wherein the composition further comprises a carrier that has substantially no effect on the expression or activity of PPAR γ in a cell of the mammal.
3. The method of claim 2 , wherein the carrier is a pharmaceutical carrier.
4. The method of claim 2 , wherein the carrier is a nutritional supplement, functional food, or dietary aid.
5. The method of claim 1 , wherein the purity of the substantially pure preparation is greater than about 95%.
6. The method of claim 1 , wherein the one or more compounds is abscisic acid in its free acid form.
7. The method of claim 1 , wherein the abcisic acid in its free acid form is chemically synthesized.
8. The method of claim 1 , wherein the amount that is sufficient to alter the expression or activity of PPAR γ in a cell of the mammal is between about 1 mg/day and about 5,000 mg/day.
