COMPOSITION FOR PREVENTING OR TREATING IMMUNE DISEASE COMPRISING METFORMIN

摘要

The present invention relates to a pharmaceutical use of a metformin compound used to prevent or treat immune diseases caused by abnormal immune responses, and more particularly, to a composition for preventing or treating immune diseases comprising a metformin compound as an active gradient. The metformin compound has excellent effects of inhibiting the differentiation into cytotoxic Th17 cells that generate and secrete inflammatory cytokine; enhancing activity of immunoregulatory T cells (Treg) that inhibit functions of abnormally activated immune cells and regulate inflammatory responses; and effectively maintaining and enhancing functions of the immunoregulatory T cells (Treg) through inhibition of plasticity of differentiation of the immunoregulatory T cells (Treg) into Th17 cells. Therefore, the metformin compound is useful as a pharmaceutical composition or an immune inhibitor capable of preventing or treating immune diseases caused by abnormal regulations of various immune responses, such as autoimmune diseases, inflammatory diseases, and transplant rejection disorders.
