The goal of our laboratory is to elucidate the pathogenic mechanism of allergies and to develop therapeutic agents. Allergy is a chronic condition involving an abnormal reaction to an ordinarily harmless substance called an allergen. What causes this over-reaction? Why are allergic diseases increasing in recent years? What kind of mechanism causes symptoms to occur due to abnormal immune response? There are still so many points to be clarified.
Therefore, we will try to establish a pathological model of allergic diseases using cells and animals, search for therapeutic targets by clarifying the cells and molecules involved in the pathogenesis of these chronic inflammatory diseases, and develop a therapeutic strategy.
Now, by conducting joint research with allergy specialists and pharmaceutical companies, we are searching for seeds of new therapeutic agents for allergic diseases and materials for functional foods.
