In Clinical Nutrition and Nutritional Immunology Laboratory, we mainly investigate the effects of nutrients, functional foods, and dietary intervention on immune and inflammatory responses, by using cell and animal experiments and human studies. Recently the role of immune cells is not only limited to protecting bodies from infectious diseases but also reported to participate in various biological processes and pathogenesis. Therefore, understanding the pathophysiology in aspects of the immune function and inflammatory response and modulating function of nutrients on it may help provide clues and strategies for the prevention and management of diseases.
