More Efficient, Flexible, Concise and Precise Genome Editing System in the Brain of Aged and/or Disease Model Mice

Potential Application for the Physiological and Pathological Research both in Human and Disease Model Animals

Genome editing technologies don’t work in cells that are no longer dividing – which include most neurons in the brain until now. Research Fellow Jun Nishiyama, M.D., Ph.D., Research Scientist, Takayasu Mikuni, M.D., Ph.D., and Scientific Director, Ryohei Yasuda, Ph.D. at the Max Planck Florida Institute for Neuroscience have developed a new tool that, for the first time, allows precise genome editing in mature nondividing neurons, opening up vast new possibilities in neuroscience research by combining CRISPR-Cas9 and Adeno-associated virus system (vSLENDR). In addition, they created a dual-viral system and applicated in an aged Alzheimer’s disease mouse model that had not been engineered to express Cas9.

These suggest the vSLENDR technique would contribute to accelerate both physiological and neuropathological studies and to the development of novel therapeutics for genetic neurological disease such as Rett syndrome in the future.
