Cells have a secret 'courier system' that could open hard-to-reach targets for RNA and gene therapies‎

Researchers at University College Dublin have discovered a previously unknown "courier system" that cells use to deliver coherent biological messages between each other, opening new possibilities for medicine and biotechnology. These courier systems also possess "keys" to natural (endogenous) gateways, allowing them to reach biological locations that are currently inaccessible in conventional delivery medicine.
