- Respiratory illness occurs when inhaling harmful substances present in the room air. Allergic reactions are characterized by immunological hypersensitivity and induce immune tolerance when protein is inhaled alone.However, innate immune reactions induce immune responses instead of protein to protein An acquired immune response (sensitization) occurs that is characterized by the memory of. If sensitization to the protein is induced, even inhalation of low concentrations of the protein can cause inflammation in the immune response to the protein. In the case of the gas among the harmful substances present in the indoor air, inflammation is induced by the toxicity of the gas itself, but does not induce inflammation by the acquired immune response. On the other hand, biological contaminants present in indoor air have both a substance and a protein that induce an innate immune response, which induces both an innate and an acquired immune response.
- Inflammation can be classified into eosinophilic and non-eosinophilic (or neutrophil) inflammation depending on whether eosinophils are infiltrated.
- Chronic inflammation is usually caused by an immune dysfunction characterized by hypersensitivity to the protein (acquired immune response), eosinophilic inflammation results in Th2 immune response to protein, neutrophil inflammation results from Th17 and / or Th1 immune response Occurs.
- the present inventors induce neutrophil inflammation upon inhalation of indoor dust, and the extracellular vesicles are the main cause of neutrophil inflammation among the components present in the indoor dust, and the activity of the extracellular vesicles is derived from Gram-negative bacteria.
- Gram-negative bacterial-derived extracellular vesicles present in indoor air are characterized by a neutrophil inflammatory response based on the fact that they are inhibited when treated with a drug (polymyxin B) that antagonizes the activity of toxins (endotoxin or lipopolysaccharide (LPS)). It was the first to identify the causative agent of respiratory diseases.
- Neutrophil pulmonary inflammation is an important pathophysiology for the development of severe asthma and chronic obstructive pulmonary disease with irreversible airway obstruction.

- E. coli-derived extracellular vesicles isolated according to the method of Example 8 was injected into the abdominal cavity of C57BL / 6 (male, 6 weeks, 10 per group) three times for three weeks at weekly intervals. Six hours, 24 hours, and 7 days after each injection, mouse blood was obtained to measure extracellular vesicle specific antibodies present in the blood. 200 ng of E. coli-derived endoplasmic reticulum was added to the mouse serum diluted 1: 500 with 1% BSA / PBS in a 96-well plate and incubated for 2 hours at room temperature, and observed through a peroxidase-coupled mouse antibody.
- E. coli-derived extracellular vesicles (EC_EV) specific antibodies in mouse blood over time.

The highest degree of antibody formation was seen after 7 days.
- splenocytes were isolated from mice 7 days after three E. coli-derived extracellular vesicles (EC_EV) inoculation was completed. 100 ng of E. coli-derived extracellular endoplasmic reticulum was added to the isolated splenocytes (2 x 10 4 ), and cultured for 72 hours, followed by the immune response-related cytokines IFN-g, IL-17 and IL-4. The amounts were each measured by ELISA method.
