A British study found that chewing can activate an immune cell called Th17 in the mouth, which can resist common bacterial and fungal infections in the mouth. Researchers fed mice with hard food in the laboratory and increased the number of chewing times when they ate. As a result, the number of Th17 immune cells in mice increased successfully, Different from the immune cells in the skin and intestines, the activation mechanism of Th17 immune cells in the mouth is unique. It is not activated by bacteria, but activated by chewing behavior, which leads to the immune response in the gums.
the purpose of the above words?
Chewing behavior can evoke gingival immune response more than bacteria.
