Medicine's next leap: Delivering gene therapies exactly where they're needed
Researchers from the University of Ottawa have developed a method for delivering gene therapies using small extracellular vesicles (sEVs) that naturally target specific tissues. The study demonstrated success in delivering siRNA to the kidneys and brain in both small and large animal models, suggesting a potential path toward human clinical trials.
