Abstract:
The present invention relates to a composition for preventing or treating arthritis or osteoporosis comprising extract of glehnia littoralis as an active ingredient. According to the present invention, the extract of glehnia littoralis has excellent activity to reduce or inhibit activity of inflammatory cytokines such as IL-17, IL-6, or TNF-, and has an improved effect of reducing osteoclast differentiation, thereby being used as a composition for preventing or treating arthritis or osteoporosis. Also, the extract of glehnia littoralis does not cause cytotoxicity, has no toxicity and side effects to the drug, thereby being safely used even in long-term use, and can be stable in vivo.
Abstract:
The present invention relates to a cell therapy composition for preventing or treating immune diseases comprising mesenchymal stem cells and immunoregulatory T-cells as active ingredients. By infusing the mesenchymal stem cells and the immunoregulatory T-cells, which are cellular therapeutic agents of the present invention, into bone marrow transplanted animals, rejection to a host is suppressed after an engraftment of the transplanted bone marrow, thereby obtaining an effect of reducing immune diseases, such as graft-versus-host disease (GVHD). Moreover, the effect of such GVHD reduction is significantly greater than that of a reduction level obtained from a sole infusion of mesenchymal stem cells. Accordingly, the cell therapy composition of the present invention having such effects can be useful in the prevention or treatment of immune diseases.

Abstract:
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.
Abstract:
The present invention relates to a monitoring kit for an immune status after transplantation, and more particularly, a monitoring kit for the immune status after the transplantation, containing materials for measuring Th17 cells, Treg cells, Th1 cells, CD8EM(CD8 effect memory) IFN-γ-positive cells, and CD8CM(CD8 central memory) IFN-γ-positive cells, and a monitoring method for the immune status of the individual receiving the transplantation including a step of measuring the cell number of Th17 cells, Treg cells, Th1 cells, CD8EM IFN-γ-positive cells, and CD8CM IFN-γ-positive cells against the peripheral blood of an object receiving the transplantation, and a step for calculating each cell number ratio of Treg cells, Th1 cells, CD8EM IFN-γ-positive cells, and CD8CM IFN-γ-positive cells against the number of Th17 cells by dividing the measured values of cell numbers of Treg cells, Th1 cells, CD8EM IFN-γ-positive cells, and CD8CM IFN-γ-positive cells with the measured value of the cell number of Th17 cells. The monitoring method and kit for the immune status of the individual receiving the transplantation provided by the present invention are capable of determining the immune status with ease and accuracy, thereby reducing the excessive use of an immunosuppressant prescribed after transplantation and managing the immune status of each patient.
