Experts from the National Institute of environmental health and Duke University have discovered the ability of flagellin - bacterial protein contained in house dust can cause an allergic reaction, which can later be allergic asthma. As told to the author Donald cook, based on the development of allergic asthma, which affects the majority of asthmatics are allergic reactions to substances that are inhaled by humans. Flagellin is not related to allergens, but can cause allergic reactions to substances that are known to be allergens.
Participating in the study mice were exposed to household dust and later showed symptoms of allergic asthma. But, as stated by the experts, not all rodents differed same response to flagellin. And an experiment involving human subjects has shown that many asthmatics have high levels of antibodies to this protein. From this it follows that there is a causal link between the environment in which people are and allergic asthma.
According to scientists, regular home cleaning reduces the amount of dust that prevents the outbreak of allergies and reduces the number of such diseases.
