Dr. Naito has been studying many years the cellular responses of cancer cells to anti-cancer drugs, including drug-induced cell death and emergence of drug resistance. His research on inhibitor of apoptosis proteins (IAPs) culminated in the development of IAP-based PROTACs, named SNIPERs, in an early development of TPD technology. He is now a project professor of the Social Cooperation Program of Targeted Protein Degradation in the University of Tokyo.
