COMPOSITION COMPRISING EXTRACELLULAR VESICLES DERIVED FROM INSIDE A MAMMALIAN BODY AND A USE THEREFOR

摘要

The present invention relates to a method or the like for treating or preventing inflammatory diseases and cancers by using extracellular vesicles isolated from inside the body of a mammal. More specifically, provided are: a composition for preventing and/or treating an inflammatory disease, which contains extracellular vesicles isolated from inside the body of a mammal as an active ingredient; and a vaccine for treating and/or preventing an inflammatory disease, which contains the extracellular vesicles as an active ingredient. Also provided is a method or the like for diagnosing the causative substance of a disease or the occurrence or progress of a disease by using the extracellular vesicles. In addition, in the present invention, extracellular vesicles derived from H. pylori isolated from stomach-disease patients can be subjected to inflammatory mediator secretion ability, intravesicular genetic material or protein analysis, vesicle and particularly immune response measurement and the like, thereby diagnosing the causative substance of the stomach disease and the occurrence or progress of the stomach disease.
