Dysbiosis (an impaired gut microbiota) is associated with a variety of diseases including not only gastrointestinal diseases but also cancer, metabolic diseases, autoimmune diseases and so on, although definition of dysbiosis has not been determined yet. Intestinal IgA is a candidate as gut microbial modulator. This project aims to improve or treat dysbiosis by intestinal IgA leading to health and longevity.
