IDAC is a unique institute affiliated with national universities that promote aging sciences. It was approved as a Joint Usage /Research Center for Aging Research and plays a center of excellence in this field. The Research Institute for Tuberculosis and Cancer, formerly called the Research Institute for Tuberculosis and Leprosy, was founded in 1941 as the second Research Institute of Tohoku University with the purpose of overcoming leprosy and tuberculosis. In 1993, reorganizations were made, and the Institute of Development, Aging and Cancer (IDAC) was created. “Aging” is defined as the phenomenon of development from birth, maturation and aging, to death. At IDAC, we study the control mechanism of aging and age-related diseases. In 2009, the Ministry of Education, Culture, Sports and Science officially recognized us as a Research Center for Aging and Cancer.
