What to know about Biotechnology

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.

Why it matters

But delivering these treatments safely and precisely to the right cells remains a major hurdle—especially in hard-to-target organs like the brain and kidneys.

Common ground

Now, researchers led by a University of Ottawa Faculty of Medicine team offer highly compelling evidence that an elegant, nature-inspired solution lies in ultra-tiny, bubble-like structures called small extracellular vesicles (sEVs).
