Division of Cell Medicine

Outline
People tend to think of stress as a psychological phenomenon, but the cells that make up our bodies can also be exposed to various kinds of physical stress caused by internal and external factors, such as high or low temperatures, UV light, nutrient starvation, hypoxia, reactive oxygen species, and malfolded protein. Our laboratory has set a goal to understand details of cell-sensing stress and defensive response to the stress at molecular, cellular, and living organism levels. We have especially considered cellular stress as an important research target from the aspect of not only basic biology but also medical science. We are interested in the relationship between stress and lifestyle diseases, inflammation, aging, cancer, neurodegenerative disorder, fatigue, sleep, and abnormal behavior. We also make efforts for the development of model animals to monitor cellular stress in vivo.
