Scientists use gold nanoparticles to edit genes tied to HIV, inherited blood disorders

Scientists at Fred Hutchinson Cancer Research Center took a step toward making gene therapy more practical by simplifying the way gene-editing instructions are delivered to cells. Using a gold nanoparticle instead of an inactivated virus, they safely delivered gene-editing tools in lab models of HIV and inherited blood disorders, as reported May 27 in Nature Materials.

It’s the first time that a gold nanoparticle loaded with CRISPR has been used to edit genes in a rare but powerful subset of blood stem cells, the source of all blood cells. The CRISPR-carrying gold nanoparticle led to successful gene editing in blood stem cells with no toxic effects.
