Abstract:
본 발명은 면역질환을 효과적으로 예방 및 치료할 수 있는 바이구아나이드(biguanide) 유도체 화합물에 관한 것이다. 본 발명의 바이구아나이드계 유도체 화합물은 염증성 사이토카인인 IL-17 및 TNF-α의 생성을 억제시키며, 면역조절 기능을 갖는 조절 T 세포의 활성을 증대시킬 뿐만 아니라, 면역질환 동물모델에 대해 우수한 치료 효과를 나타낸다. 따라서 각종 면역반응의 조절 이상으로 유발되는 자가면역질환, 염증성질환 및 이식거부질환과 같은 면역질환을 예방 또는 치료할 수 있는 약학적 조성물 또는 면역 억제제로 유용하게 사용될 수 있다.
Abstract:
The present invention relates to a composition for preventing or treating immune diseases by suppressing B cell activities which are induced by metformin and, more specifically, to a composition for preventing or treating immune diseases, which includes a metformin compound or pharmaceutically acceptable salts thereof. The composition suppresses or reduces activities of etiological B cells. According to the present invention, the composition for preventing or treating immune diseases can be used as an immune suppressor by suppressing or reducing the etiological B cells in various autoimmune diseases, suppressing or reducing activities of etiological Th17 cells, and promoting or increasing activities of regulatory T cells (Treg).
Abstract:
PURPOSE: A composition containing mesenchymal stem cells for treating autoimmune diseases is provided to improve immunity and to prevent dermatitis which is a side effect of a steroid formulation, thereby being used as a safety therapeutic agent for treating autoimmune diseases. CONSTITUTION: A composition for treating autoimmune diseases contains mesenchymal stem cells. The composition treats autoimmune diseases by promoting the generation or activation of regulatory B cells or suppressing the generation of antibody producing B cells. The regulatory B cells are B reg or B10 cells. The B cells are CD19+CD1d+CD5+ B cells or marginal zone B cells.
Abstract:
PURPOSE: A composition containing myeloid derived suppressor cells as active ingredients for preventing or treating transplant rejection or autoimmune diseases is provided to promote generation of regulatory B cells and activation of antibody-producing B cells, thereby treating immune diseases including autoimmune diseases. CONSTITUTION: A composition for preventing or treating transplant rejection or autoimmune diseases contains myeloid derived suppressor cells. Myeloid derived suppressor cells are isolated and differentiated from bone marrow of an individual with immune diseases. The composition promotes generation of regulatory B cells or suppresses activation of antibody-producing B cells. Myeloid derived suppressor cells are differentiated by GM-CSF or M-CSF. Myeloid derived suppressor cells have CD11b^+Gr-1^+ marker by induction of differentiation.
Abstract:
PURPOSE: A cell therapeutic composition is provided to effectively suppress immune rejection from a transplant process, and to prevent or treat graft-versus-host disease. CONSTITUTION: A pharmaceutical composition for preventing or treating graft-versus-host disease contains 1ug/ul-3ug/ul of genes which suppresses an IL-21 receptor and 2x10^5-2x10^7 mesenchymal stem cells as an active ingredient. The mesenchymal stem cells are derived from human.
Abstract:
PURPOSE: A composition containing retinal for preventing or treating cancer or immune diseases is provided to enhance immune-modulating T cell activity. CONSTITUTION: A composition for preventing or treating cancer or immune disease contains retinal compounds of pharmaceutically acceptable salt thereof as an active ingredient. The retinal promotes or enhances regulatory T cell activity or proliferation. A method for reducing or suppressing differentiation of immature T cell into Th17 cell in vitro comprises a step of treating retinal compound or pharmaceutically acceptable salt to the undifferentiated T cells.
Abstract:
PURPOSE: A mesenchymsal stem cells and a composition containing the same for treating autoimmune diseases are provided to enhance autoantigen-specific CD4+ CD25+ Foxp3+ regulatory T cells and to treat autoimmune diseases. CONSTITUTION: A composition for treating autoimmune diseases contains mesenchymal stem cells in which TFG-beta-encoding nucleotide sequence is introduced and pharmaceutically acceptable carrier. The TGF-beta-encoding nucleotide sequence is sequence number 2. The TGF-beta-encoding nucleotide sequence is introduced by adenovirus-associated vector. The mesenchymal stem cell is derived from bone marrow-derived mesenchymal stem cells or adipose-derived mesenchymal stem cells.
