Abstract:
PURPOSE: A composition containing an extracellular vesicle derived from Akkermansia muciniphila or Bacteroides acidifaciens is provided to suppress inflammatory diseases. CONSTITUTION: A composition for preventing or treating inflammatory diseases contains an extracellular vesicle derived from Akkermansia muciniphila or Bacteroides acidifaciens. The extracellular vesicle is naturally or artificially secreted from Akkermansia muciniphila or Bacteroides acidifaciens. The average diameter of the extracellular vesicle is 20-800 nm. The composition is a pharmaceutical composition.
Abstract:
PURPOSE: A method for treating or preventing Th17 inflammatory diseases and a pharmaceutical composition for the same are provided to treat non-eosinophilic or neutrophilc inflammatory diseases. CONSTITUTION: A pharmaceutical composition for preventing or treating Th17 inflammatory diseases contains VEGFR(vascular endothelial growth factor receptor) pathway inhibitor as an active ingredient. The Th17 inflammatory diseases are non-eosinophilic or neutrophilc inflammatory diseases. The inhibitor is semaxanib(SU5416). The Th17 inflammatory diseases are prevented or treated by administering the pharmaceutical composition containing VEFGR pathway inhibitor to an mammal.
Abstract:
PURPOSE: A combination formulation for effectively preventing or treating IL-17-mediated inflammatory diseases by combined administration of drugs is provided. CONSTITUTION: A combined formulation for preventing or treating IL-17-mediated inflammatory diseases contains: an adenosine generation promoter, Th2 cytokine inhibitor or signal transduction inhibitor thereof, and a drug which suppresses uric acid generation or promoting uric acid degradation. The adenosine generation promoter is aspirin, derivative or salt thereof. The Th2 cytokine is IL-4, IL-5, IL-9, or IL-13.
Abstract:
PURPOSE: A drug delivery system using hyaluronic acid - peptide conjugate micelle Is provided to be applied to human body by being filled in biodegradable derivative. CONSTITUTION: A drug delivery system is composed of a shell domain which includes hyaluronic acid or pharmaceutically acceptable salt and a core domain which includes water-immiscible peptides. The water-immiscible peptide comprises micelle combined with pharmaceutically acceptable salt or hyaluronic acid and water-immiscibility drug filled inside the micelle. The hyaluronic acid or the pharmaceutically-acceptable salt thereof has the molecular weight of 10,000-3,000,000 daltons(Da). The hyaluronic acid or the pharmaceutically-acceptable salt thereof is a compound represented by chemical formula 1. The water-immiscibility peptide is combined as the number of molecules corresponding to 4-15% of integers of monomer number per each molecule of the chemical formula 1.
Abstract:
PURPOSE: A method for treating and/or diagnosing cancer using bacteria-derived micro vesicles is provided to enhance anti-cancer efficiency and to reduce side effect to a therapeutic agent. CONSTITUTION: A pharmaceutical composition for treating or diagnosing cancer contains bacteria-derived microvesicles. The bacteria express a material for treating or diagnosing cancer and a material for targeting cancer cells or tissues. The composition additionally contains a drug for inhibiting toxicity by the micro vesicles. The drug is loaded to the micro vesicles. The drug is polymyxin B or aspirin. The membrane of the micro vesicle is modified chemically. A method for preparing the microvesicle comprises: a step of adding the drug to suspension containing the bacteria or transformed bacteria or mixture suspension containing the bacteria or transformed bacteria and drug; and a step of isolating loaded micro vesicles.
