Recent years have witnessed growing clinical approvals of new drug classes, including nucleic acid therapeutics, gene therapy, and mRNA vaccines, changing the concept of drugs. These new classes of drugs control the functionalities of target genes and proteins to treat diseases at molecular levels, providing hopeful options for intractable disease treatment with reduced adverse effects. Developing such new drugs requires interdisciplinary research. For example, mRNA vaccine development involves chemistry and engineering for mRNA manufacturing and nano-drug delivery systems (DDS), molecular biology and immunology of mRNA, and medical research on vaccine effects and adverse outcomes. In this interdisciplinary field, our laboratory develops nano DDSs, evaluates their biological properties, and applies them to disease treatment, focusing on mRNA vaccines and therapeutics. Moreover, we attempt clinical translation in collaboration with companies. Notably, our research interests include basic research for understanding biological processes we observe in application studies.
