New technology facilitates delivery of advanced medicines

Researchers at Karolinska Institutet in Sweden have developed a technique that enables efficient delivery of therapeutic proteins and RNA to cells. The method, presented in Nature Communications, shows promising results in animal studies to deliver gene editors and protein therapeutics.

The method is based on so-called extracellular vesicles (EVs), tiny bubbles that are naturally secreted by cells and can transport biologically active molecules between cells. Researchers have now succeeded in improving these bubbles by introducing two key components: a small part of a bacterial protein called intein and a so-called fusogenic protein from a…
