Patent ID: 11554144

Abstract:
Provided are vesicles derived from Enhydrobacter bacteria and a use thereof, and the inventors experimentally confirmed that the vesicles were significantly reduced in clinical samples obtained from patients with pancreatic cancer, cholangiocarcinoma, breast cancer, ovarian cancer, lymphoma, myocardial infarction, cardiomyopathy, atrial fibrillation, variant angina, liver cirrhosis, and diabetes, compared with a normal individual, and that when vesicles isolated from the strain were administered, the secretion of inflammatory mediators caused by pathogenic vesicles, such as E. coli-derived vesicles, was significantly inhibited. Therefore, it is expected that the vesicles derived from Enhydrobacter bacteria according to the present invention can be effectively used for a method of diagnosing pancreatic cancer, cholangiocarcinoma, breast cancer, ovarian cancer, lymphoma, myocardial infarction, cardiomyopathy, atrial fibrillation, variant angina, liver cirrhosis, or diabetes, and for developing a composition for preventing, alleviating or treating the diseases.
