In vivo neuronal gene editing via CRISPR-Cas9 amphiphilic nanocomplexes alleviates deficits in mouse models of Alzheimer's disease

摘要

In vivo gene editing in post-mitotic neurons of the adult brain may be a useful strategy for treating neurological diseases. Here, we develop CRISPR-Cas9 nanocomplexes and show they were effective in the adult mouse brain, with minimal off-target effects. Using this system to target Bacel suppressed amyloid beta (A beta)-associated pathologies and cognitive deficits in two mouse models of Alzheimer's disease. These results broaden the potential application of CRISPR-Cas9 systems to neurodegenerative diseases.
