Research theme
Research for the realisation of gene therapy using genome editing technology.
Genome editing technology via CRISPR-Cas9 is expected to be a promising therapeutic approach for congenital genetic diseases. However, there are still several barriers to overcome for the realisation of gene therapy using genome editing, including the inadequate genome editing efficiency of Cas9, the problem of how to deliver Cas9 to target tissues, and immune responses against Cas9.I am collecting basic knowledge to solve the above issues and conducting research on solutions to these issues by making full use of various viral vectors carrying Cas9.
