Description
본 발명은 베일로넬라 속 세균 유래 나노소포 및 이의 용도에 관한 것으로, 보다 구체적으로 베일로넬라 속 세균에서 유래하는 나노소포를 이용한 위암, 간암, 췌장암, 폐암, 심근경색, 심방세동, 뇌졸중, 또는 당뇨병 등의 진단방법, 및 상기 소포를 포함하는 상기 질환의 예방, 개선 또는 치료용 조성물에 관한 것이다. The present invention relates to a nano-vesicle derived from bacteria of the genus Baylonella and uses thereof, more specifically gastric cancer, liver cancer, pancreatic cancer, lung cancer, myocardial infarction, atrial fibrillation, stroke, or It relates to a diagnostic method, such as diabetes, and a composition for preventing, improving or treating the disease, including the vesicle.
21세기에 들어서면서 과거 전염병으로 인식되던 급성 감염성질환의 중요성이 덜해지는 반면, 인간과 마이크로바이옴과의 부조화에 의해 발생하는 면역기능 이상을 동반한 만성질환이 삶의 질과 인간 수명을 결정하는 주요 질환으로 질병패턴이 바뀌었다. 21세기 난치성 만성질환으로서, 암, 심혈관질환, 만성폐질환, 대사질환, 및 신경-정신질환이 인간 수명과 삶의 질을 결정하는 주요 질환으로서 국민보건에 큰 문제가 되고 있다.In the 21st century, while the importance of acute infectious diseases, which were previously recognized as infectious diseases, has become less important, chronic diseases accompanied by immune dysfunction caused by mismatch between humans and microbiomes determine the quality of life and human life. The disease pattern has changed to a major disease. As a refractory chronic disease in the 21st century, cancer, cardiovascular disease, chronic lung disease, metabolic disease, and neuro-psychiatric disease are major diseases that determine human lifespan and quality of life, and have become a major problem in public health.
인체에 공생하는 미생물은 100조에 이르러 인간 세포보다 10배 많으며, 미생물의 유전자수는 인간 유전자수의 100배가 넘는 것으로 알려지고 있다. 미생물총(microbiota 혹은 microbiome)은 주어진 거주지에 존재하는 진정세균(bacteria), 고세균(archaea), 진핵생물(eukarya)을 포함한 미생물 군집(microbial community)을 말한다. It is known that the microorganisms that symbiotic with the human body reach 100 trillion times and are 10 times more than human cells, and the number of genes in the microorganism is more than 100 times that of the human gene. Microbiota (microbiota) refers to a microbial community (microbial community), including bacteria, archae, and eukarya.
우리 몸에 공생하는 세균 및 주변 환경에 존재하는 세균은 다른 세포로의 유전자, 저분자화합물, 단백질 등의 정보를 교환하기 위하여 나노미터 크기의 소포(vesicle)를 분비한다. 점막은 200 나노미터(nm) 크기 이상의 입자는 통과할 수 없는 물리적인 방어막을 형성하여 점막에 공생하는 세균인 경우에는 점막을 통과하지 못하지만, 세균 유래 소포는 크기가 100 나노미터 크기 이하라서 비교적 자유롭게 점막을 통하여 상피세포를 통과하여 우리 몸에 흡수된다. 국소적으로 분비된 세균 유래 소포는 점막의 상피세포를 통해 흡수되어 국소 염증반응을 유도할 뿐만 아니라, 상피세포를 통과한 소포는 림프관을 통해 전신적으로 흡수되어 각 장기로 분포하고, 분포된 장기에서 면역 및 염증반응을 조절한다. 예를 들어, 대장균(Eshcherichia coli)와 같은 병원성 그람음성세균에서 유래하는 소포는 국소적으로 대장염을 일으키고, 혈관으로 흡수된 경우에 혈관 내피세포 염증반응을 통해 전신적인 염증반응 및 혈액응고를 촉진시키고, 또한 인슐린이 작용하는 근육세포 등에 흡수되어선 인슐린저항성과 당뇨병을 유발한다. 반면, 유익한 세균에서 유래하는 소포는 병원성 소포에 의한 면역기능 및 대사기능 이상을 조절하여 질병을 조절할 수 있다. Bacteria that live in our bodies and bacteria that exist in the surrounding environment secrete nanometer-sized vesicles to exchange information such as genes, low-molecular compounds, and proteins into other cells. The mucous membrane forms a physical barrier that cannot pass particles over 200 nanometers (nm) in size, and in the case of bacteria that symbiotic with the mucous membrane, the mucosa cannot pass through the mucous membrane, but the bacterial-derived vesicles are less than 100 nanometers in size. It passes through epithelial cells through the mucous membrane and is absorbed by our body. Locally secreted bacterial-derived vesicles are absorbed through epithelial cells of the mucous membrane to induce a local inflammatory response. In addition, vesicles that have passed through the epithelial cells are absorbed systemically through the lymphatic vessels, distributed to each organ, and distributed organs. It regulates immune and inflammatory responses. For example, vesicles derived from pathogenic Gram-negative bacteria such as E. coli ( Eshcherichia coli ) locally develop colitis and, when absorbed into blood vessels, promote systemic inflammatory and blood coagulation through vascular endothelial inflammatory responses. In addition, insulin is absorbed by muscle cells, etc., which act, and causes insulin resistance and diabetes. On the other hand, vesicles derived from beneficial bacteria can control disease by controlling immune and metabolic abnormalities caused by pathogenic vesicles.
세균에서 유래하는 소포 등의 인자에 대한 면역반응은 인터루킨(Interleukin, 이하 IL)-17 사이토카인 분비를 특징으로 하는 Th17 면역반응이 발생하는데, 이는 세균 유래 소포에 노출 시 IL-6가 분비되고, 이는 Th17 면역반응을 유도한다. Th17 면역반응에 의한 염증은 호중구 침윤을 특징으로 하고, 염증이 발생하는 과정에서 호중구, 대식세포 등과 같은 염증세포에서 분비되는 종양괴사인자-알파(tumor necrosis factor-alpha, 이하 TNF-α)가 중요한 역할을 담당한다.The immune response to factors such as bacterial-derived vesicles produces a Th17 immune response characterized by the secretion of interleukin-17 cytokines, which secrete IL-6 upon exposure to bacterial-derived vesicles, This induces a Th17 immune response. Inflammation due to Th17 immune response is characterized by neutrophil infiltration, and tumor necrosis factor-alpha (hereinafter referred to as TNF-α) secreted from inflammatory cells such as neutrophils and macrophages in the process of inflammation is important. It plays a role.
