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

Researchers at University College Dublin discovered a cellular 'courier system' that enables the transfer of biomolecules between cells, potentially revolutionizing RNA and gene therapies. The study, published in Nature Materials, describes how nanoparticles acquire a protein-RNA coating that allows them to bypass cellular barriers and deliver functional molecules to target cells.

What happened

Cells have a secret 'courier system' that could open hard-to-reach targets for RNA and gene therapies Sadie Harley scientific editor Robert Egan associate editor Researchers at University College Dublin have discovered a previously unknown "courier system"…

Why it matters

These courier systems also possess "keys" to natural (endogenous) gateways, allowing them to reach biological locations that are currently inaccessible in conventional delivery medicine.

Common ground

"By gaining access to these natural gateways, it could be possible to ferry 'toolkits' of functional biomolecules, for example extended corrective messages, directly into previously inaccessible areas within cells, and across biological barriers, greatly…
