[특허 요약] The present invention relates to a yeast-derived polysaccharide inducing Treg cells and a use thereof and, more particularly, to a polysaccharide comprising mannan and β-glucan, an composition for immunomodulation comprising the polysaccharide as an active ingredient, a pharmaceutical composition or food comprising the polysaccharide as an active ingredient for prevention or treatment of immune disease or inflammatory disease, a method for preparation of regulatory T cells by using the polysaccharide, a cell therapeutic agent comprising the regulatory T cells prepared by the preparation method as an active ingredient, and a treatment method using same. Even at a low dose, the novel polysaccharide according to the present invention allows the production of tolerogenic antigen presenting cells through the β-glucan and mannan structure retained therein, whereby the novel polysaccharide can induce the differentiation or production of antigen-specific regulatory T cells (Treg cells) to modulate the target immune system with low adverse effects. Therefore, MGCP and the Treg cells induced by the polysaccharide are effective for preventing or treating immune disease or inflammatory disease.
