Radiology's role in gene therapy: Image and deliver
... Viruses attach to specific cells and deploy their contents into the cells, including any genes they might be carrying. But viruses might also attack the cells. An alternative and safer delivery method is via liposomes, which are commonly used to deliver medicines to the body.
