Dr. Fujita is Professor of Molecular Genetics at Kyoto University’s Institute for Virus Research. He received his B.A. in Biology in 1977 and his Ph.D. in Biology in 1982; both at Waseda University in Tokyo, Japan. Dr. Fujita’s lab discovered that an RNA helicase, RIG-I, functions as such a sensor. The laboratory is working to clarify the molecular mechanism underlying the antiviral innate immunity regulated by RIG-I, and to develop new diagnostic and therapeutic tools for viral infections and cancer.
