This article describes attaching a drug molecule to a molecule from the rabies virus that enables the drug to cross the blood-brain barrier. This suggests a possible danger if the ability to produce the molecule could be transferred to the genomes of disease organisms in the wild. If the field of genetic engineering for drug production doesn’t already have guidelines to cover such risks, now might be the time to develop them.
