Researchers from the Netherlands Institute for Neuroscience and the Leiden University Medical Center have shown that treatment using gene therapy leads to a faster recovery after nerve damage.
By combining a surgical repair procedure with gene therapy, the survival of nerve cells and regeneration of nerve fibers over a long distance was stimulated for the first time.
The discovery, published in the journal Brain, is an important step towards the development of a new treatment for people with nerve damage.
During birth or following a traffic accident, nerves in the neck can be torn out of the spinal cord. As a result, these patients lose their arm function, and are unable to perform daily activities such as drinking a cup of coffee. Currently, surgical repair is the only available treatment for patients suffering this kind of nerve damage. ‘After surgery, nerve fibers have to bridge many centimeters before reaching the muscles and nerve cells from which new fibers need to regenerate are lost in large numbers. Most regenerating nerve fiber do not reach the muscles. The recovery of arm function is therefore disappointing and incomplete,’ explains researcher Ruben Eggers of the NIN.
