CRISPR-Cas is a gene editing tool that can be used to edit specific genes. In this case, the researcher used it to edit the exon of the mutant HTT gene in mice. The therapeutic was injected into the brain after the editing was done, and it led to a reduction in protein aggregates in the mice. The other options, lentiviral transfection, TALENs, and ZFNs, are also gene editing tools, but they are not as efficient and precise as CRISPR-Cas.
