Abstract:
The present invention relates to a composition containing coenzyme Q10 as an active ingredient for preventing or treating inflammatory diseases or immune rejection. More particularly, coenzyme Q10 suppresses or reduces the activity of Th17 and effectively promotes or enhances the activity of regulatory T cells (Treg), thereby being used as a composition for preventing or treating immune rejection such as graft rejection or inflammatory diseases. In addition, coenzyme Q10 does not cause cytotoxicity and the side effects to the drug is not toxic, thereby being safely administered in the long-term and being stable in the body.
Abstract:
PURPOSE: An antioxidant is provided to effectively enhance the expression of Rcan3 gene and to be used as an immunosuppressive agent for treating or preventing immune diseases because Rcan3 protein suppresses calcineurin pathway. CONSTITUTION: An antioxidant increases the expression of Rcan3 gene. The antioxidant is rebamipide or polyphenol compounds. The polyphenol compounds are proanthocyanidin. A method for increasing the expression of Rcan3 in vitro comprises the step of treating cells with the antioxidant. A composition for preventing or treating immune disease contains Rcan3 gene or protein as an active ingredient.
