- chronic diseases accompanied by immune function abnormalities caused by mismatch between humans and symbiotic microorganisms and aging related to major organs of the body
- the disease pattern has changed as chronic disease is a major disease that reduces the quality of life and determines the longevity of human beings.
- chronic disease intractable chronic disease characterized by abnormalities in immune and metabolic functions caused by various stresses, cancer, cardiovascular disease, chronic lung disease, metabolic disease, and neuro-psychiatric disease are the major factors that determine human lifespan and quality of life. As a disease, it has become a major problem in public health.
- Aging refers to a decline in the function of body organs over time, and the accumulation of cellular damage over time is regarded as a common cause of aging. It was found that the NLRP3 inflammasome, which is activated in response to various damage-associated molecular patterns (DAMPs), which increases with age, is particularly closely related to aging. Therefore, the NLRP3 inflammasome has been a target for the prevention and treatment of aging-related diseases, and aging-related chronic diseases are characterized by chronic inflammation and apoptosis accompanied by abnormalities in immune and metabolic functions. It is reported to be able to suppress the disease.
- DAMPs damage-associated molecular patterns
- Immunity is a defense mechanism of cells against biological, chemical, physical, and mental stress, and occurs through innate immunity and adaptive immunity.
- PAMP pathogen-associated molecular pattern

- Metabolism is the process of making energy for our body and making various substances to perform cell functions. Proteins and lipids are made in the endoplasmic reticulum (ER) through ATP made in mitochondria, and the substances are supplied to the required area. . Cells face various stresses from the moment they are created. Biological, chemical, physical, and mental stress induce ER stress, mitochondrial dysfunction, and lysosomal damage within the cell, thereby activating the NLRP3 inflammasome. It induces apoptosis and causes various diseases.

- the retina of the eye is an organ belonging to the central nervous system, and mature retinal cells do not divide under normal conditions like most neuronal cells in the brain. Therefore, when the function of the retinal cells is reduced, abnormalities in the visual function are likely to appear, and aging proceeds rapidly. Oxidative stress is the biggest cause of the deterioration of retinal cell function.

Regulates immune and inflammatory responses.
- vesicles derived from pathogenic Gram-negative bacteria such as Escherichia coli are pathogenic nanoparticles mimicking viruses and cause colitis locally, and when absorbed into blood vessels, systemic vesicles through vascular endothelial cell inflammatory response It promotes inflammatory response and blood clotting, and is absorbed into muscle cells where insulin acts, leading to insulin resistance and diabetes.
- vesicles derived from beneficial bacteria can control diseases by regulating abnormalities in immune and metabolic functions caused by pathogenic vesicles.
- Micrococcus luteus is a gram-positive bacterium belonging to the genus Micrococcus, and is a bacterium widely distributed in nature such as water, dust, soil, and the like. This bacterium is known to produce riboflavin when grown in toxic organic pollutants such as pyridine and to absorb ultraviolet light through lutein pigment.
