Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

Abstract: The present invention relates to a pharmaceutical composition comprising a novel compound as an active ingredient for prevention or treatment of transplant rejection. The novel compound SD911 of the present invention was identified to repress the migration of immune cells, increase the engraftment and viability of a grafted tissue, and regulate immune cells. In addition, it was found in a kidney transplantation model that the compound restrained human PBMC from suppressing the engraftment and damaging renal tissues and downregulated the expression of the inflammatory cytokine IL-17, with the consequent effective prevention and treatment of transplant rejection.

Abstract: The present disclosure relates to a method for inhibiting a STAT3 activity comprising administering SSu72 protein.

Abstract: Provided is a novel compound and use thereof which has an excellent immunological regulation ability while not exhibiting toxicity in vivo, and has no nephrotoxicity and rather has a kidney protective effect, and thus can be used for the treatment of immune diseases such as autoimmune diseases caused by abnormal regulation of various immune responses, inflammatory diseases, and transplant rejection diseases. A transplant rejection avatar animal model was confirmed to be humanized, by confirming an increase in serum creatinine, an indicator of transplant rejection in a patient, an increase in human CD4-positive cells, and infiltration of inflammatory cytokine IL-17 into kidney tissue of the animal model. It was confirmed that, when an immunosuppressant is administered, the increased serum creatinine, human CD4-positive cells, and the infiltration of inflammatory cytokine IL-17 are reduced, and thus an animal model, in which the immune status of a patient is reflected, is effectively constructed.

Abstract: The present invention relates to a composition which is for preventing or treating bone diseases and includes CCR2 as an active ingredient. It was confirmed that a C—C chemokine receptor type 2 (CCR2) protein, a polynucleotide encoding the CCR2 protein, or a mesenchymal stem cell transduced with the CCR2 according to the present invention neutralize bone disease factor MCP-1, thereby reducing the collagen epitope (CTX-II) and collagen metabolism factors (MMP1 and MMP3) relating to collagen absorption in the body. In addition, it was confirmed that the expression of the SOX9 gene and anti-inflammatory cytokines (TGF-? and IL-10) related to cartilage differentiation was significantly increased. Thus, the present invention has excellent regenerative ability against osteoarthritis and excellent pain suppression and alleviation effects, and thus can be effectively used for preventing or treating bone diseases such as osteoarthritis.

Abstract: The present invention relates to: a recombinant peptide in which a Mitochondria Localization Sequence (MLS) peptide and the Signal Transducer and Activator of Transcription 3 (STAT3) are fused to each other; a recombinant vector carrying a polynucleotide coding for the recombinant peptide; and a composition comprising the recombinant peptide or the recombinant vector as an active ingredient for prevention or treatment of autoimmune disease or inflammatory disease, wherein the recombinant peptide or the recombinant vector allows STAT3 to be overexpressed in the mitochondria to enhance the mitochondrial function, resulting in inhibiting the expression of inflammatory cytokines including IL-17, whereby the composition may be advantageously used for preventing or treating autoimmune disease or inflammatory diseases.

Abstract: The present invention relates to a novel complex that is formed by linking p40 subunit and EBI3 subunit via a linker and has excellent anti-inflammatory effects and immunomodulatory effects.

Abstract: Disclosed are a novel Bifidobacterium longum RAPO (Accession No.: KCTC 13773BP) and a composition for alleviating, treating or preventing rheumatoid arthritis containing Bifidobacterium longum RAPO (Accession No.: KCTC 13773BP) selected herein.

Abstract: The present disclosure relates to a method for inhibiting a STAT3 activity, and a method for treating inflammatory bowel disease (IBD).

Abstract: Disclosed are a novel Bifidobacterium longum RAPO (Accession No.: KCTC 13773BP) and a composition for alleviating, treating or preventing rheumatoid arthritis containing Bifidobacterium longum RAPO (Accession No.: KCTC 13773BP) selected herein.

Abstract: The present disclosure relates to a method of preventing rheumatoid arthritis comprising administering a polynucleotide encoding Ssu72.

Abstract: The present invention relates to a mesenchymal stem cell having immunomodulatory activity and a preparation method therefor and, more specifically, to: a rapamycin-treated mesenchymal stem cell having immunomodulatory activity, which expresses any one or more cell surface factors selected from the group consisting of CCR1, CCR2, CCR3, CCR4, CCR7, CCR9 and CXCR4; a cell therapy composition comprising the mesenchymal stem cell, for preventing or treating immune disorders; and a preparation method for the mesenchymal stem cell having immunomodulatory activity. The rapamycin-treated mesenchymal stem cell having immunomodulatory activity, according to the present invention, has increased expression of IDO, TGF-? and IL-10 which are factors having immunomodulatory activity, has decreased expression of Phospho-mTOR, Rictor and Ractor which are signal transduction factors of mTOR, and has increased expression, in the cell, of autophagic inducer Beclin1, ATG5, ATG7, LC3I or LCII.

Abstract: The present invention relates to a cell therapy composition for preventing or treating immune disease comprising mesenchymal stem cells and immunoregulatory T-cells as an active ingredient. By infusing mesenchymal stem cells and immunoregulatory T-cells, which are the cellular therapeutic agent of the present invention, into bone marrow transplant animals, rejection to the host is suppressed after the engraftment of the transplanted bone-marrow to thus obtain the effect of reducing graft-versus-host disease and immune disease. Moreover, the effect of such GVHD reduction is much greater than the one obtained when only mesenchymal stem cells are infused. Accordingly, the cell therapy composition of the present invention having the above-mentioned effects can be useful in the prevention or treatment of immune disease.
