A sound approach for effective gene therapy delivery to brain

Researchers have been experimenting with different ways to deliver genes to the brain to treat central nervous system diseases and tumors. One of the obstacles, however, is the ability to penetrate the blood-brain barrier while having minimal effect on the other organs in the body.

Hong Chen, PhD, associate professor of biomedical engineering at the McKelvey School of Engineering and of radiation oncology at the School of Medicine, both at Washington University in St. Louis, and her team found an effective method to overcome that obstacle using focused ultrasound intranasal delivery (FUSIN). In new research, they found that the intranasally delivered gene therapy had comparable or better outcomes than existing methods while having minimal effect on the body’s other organs.
