Abstract:
PURPOSE: An antioxidant is provided to effectively enhance the expression of Rcan3 gene and to be used as an immunosuppressive agent for treating or preventing immune diseases because Rcan3 protein suppresses calcineurin pathway. CONSTITUTION: An antioxidant increases the expression of Rcan3 gene. The antioxidant is rebamipide or polyphenol compounds. The polyphenol compounds are proanthocyanidin. A method for increasing the expression of Rcan3 in vitro comprises the step of treating cells with the antioxidant. A composition for preventing or treating immune disease contains Rcan3 gene or protein as an active ingredient.
Abstract:
본 발명은 STA-21을 유효성분으로 포함하는 암 또는 면역질환의 예방 및 치료용 조성물에 관한 것으로서, 보다 구체적으로 본 발명은 STA-21을 화합물 또는 그의 약학적으로 허용 가능한 염을 유효성분으로 함유하는 암 또는 면역질환의 예방 및 치료용 조성물, 면역억제용 조성물, STA-21을 이용한 미분화 T 세포의 Th17 세포로의 분화를 감소 또는 억제하는 방법 및 조절 T 세포를 활성화시키는 방법에 관한 것이다. 본 발명에 따른 STA-21 화합물은 염증성 사이토카인을 생성 및 분비하는 세포 독성 Th17 세포의 분화를 억제하는 효과가 우수하고, 비정상적으로 활성화된 면역세포의 기능을 억제하고 염증 반응을 제어하는 특성을 갖는 면역조절 T 세포(Treg)를 활성화 시키는 효과가 우수하므로 면역반응의 조절 이상으로 유발되는 자가면역질환, 염증성질환 및 이식거부질환과 같은 면역질환을 예방 및 치료할 수 있는 약학적 조성물 또는 면역 억제제로 유용하게 사용될 수 있는 효과가 있다.
Abstract:
PURPOSE: A composition for preventing and treating immunization diseases including nutlin-3a compound is provided to suppress the expression of IL-17 through overexpression of p53. CONSTITUTION: A composition for preventing and treating immunization diseases includes nutlin-3a compound. The nutlin-3a compound suppresses the IL-17 production. The IL-17 production suppression is completed by the overexpression of p53. The immunization disease is autoimmune disease, inflammation disease, transplantation rejection disease of cell, tissue or organ. The autoimmune disease or inflammation disease is rheumatoid arthritis, asthma], dermatitis, psoriasis, cystic fibrosis, multiple sclerosis, systemic lupus erythematosus, sjogren syndrome, hashimoto thyroiditis, polymyositis, scleroderma, Addison disease, vitiligo, pernicious anemia, glomerulonephritis, pulmonary fibrosis, inflammatory Bowel dieseses, autoimmune diabetes, diabetic retinopathy, rhinitis, ischemia-reperfusion injury, post-angioplasty restenosis, chronic obstructive pulmonary diseases(COPD), Graves disease, gastrointestinal allergies, conjunctivitis, and atherosclerosis. [Reference numerals] (AA) Producing amount of IL-17(pg/ml)
Abstract:
PURPOSE: A composition containing AG490 compounds is provided to enhance regulatory T cell(Treg) activity and to prevent or treat immune diseases. CONSTITUTION: A composition for preventing or treating immune diseases contains AG490 compounds of chemical formula 1 or pharmaceutically acceptable salt thereof as an active ingredient. The immune diseases are autoimmune diseases, inflammatory diseases, and transplantation rejection. A method for reducing or suppressing differentiation of undifferentiated T cells in vitro into Th17 cells comprises a step of treating AG490 compounds or pharmaceutically acceptable salt thereof to the undifferentiated T cells.
Abstract:
PURPOSE: A TNFR2-IL21R fusion protein as a double antagonist to TNF-alpha and IL-21 is provided to reduce inflammatory cytokine secretion and to increase anti-inflammatory cytokine secretion. CONSTITUTION: A composition for preventing and treating autoimmune disease contains a fusion protein having a fragment with extracellular region of TNFR2(Tumor necrosis factor receptor type 2) or TNFR2 and a fragment with extracellular region of IL21R(Interleukin-21 receptor) protein or IL21R as an active ingredient. The fusion protein has an amino acid sequence of sequence number 1.
