Researchers have used the gene-editing technique CRISPR to delete a segment of DNA associated with autism and schizophrenia from mouse brain cells.
The technique has only proven effective in mice so far but may eventually be suitable for treating brain conditions in people, says Xiao-hong Lu, assistant professor of pharmacology and neuroscience at Louisiana State University Health in Shreveport.
Unlike techniques used to manipulate DNA in the mouse brain, CRISPR can be applied to people. He says, “We need a tool to help us to carry the genetic elements into the [human] brain.”
