How can nerves heal

So far we have been able to show that the material remaining at the injection site is slowly decreasing. However, whether this is due to biological degradation or the distribution in the body requires further investigation. As shown by the laboratory experiment in mice, initial damage to nerve tracts can be repaired using our artificial matrix. Before using the material in clinical applications, however, further optimisation is required since the nerve cells on our material do not grow as well yet as they do in the natural matrix.

They also grow in a quite disordered manner in all directions. Our next step will be to embed so-called growth factors into the artificial matrix to further accelerate the healing process. Furthermore, we want to orient the injected fibre structures to assist the nerve cells to grow in a specific direction. We are confident that our artificial extracellular matrix could represent a good alternative to complex surgery for minor injuries to nerve tracts. Further research might also lead to a method of treating not just injuries to the peripheral nervous system but also to the central nervous system.

A number of tests may be used to help diagnose the type and severity of peripheral nerve injuries. When you make your appointment, be sure to ask whether you need to prepare for these tests. For instance, you may need to stop taking certain medications for a few days or avoid using lotions the day of the test. If possible, take along a family member or friend. Sometimes it can be difficult to absorb all the information you're given during an appointment.

Peripheral nerve graft Open pop-up dialog box Close. Peripheral nerve graft To repair a damaged nerve, your surgeon removes a small part of the sural nerve in your leg and implants this nerve at the site of the repair. Nerve transfer Open pop-up dialog box Close. Nerve transfer Your surgeon can bypass a damaged section of nerve by reconnecting a healthy nerve to restore function.

There is definitely an urgent need for the development of new strategies for patients with spinal cord injury. When the researchers looked in three injury models in the spinal cord and brain, they observed that Syntaphilin knockout mice had significantly more axon regrowth across the injury site compared to control animals.

The newly grown axons also made appropriate connections beyond the injury site. When the researchers looked at whether this regrowth led to functional recovery, they saw some promising improvement in fine motor tasks in mouse forelimbs and fingers.

This suggested that increasing mitochondrial transport and thus the available energy to the injury site could be key to repairing damaged nerve fibers.

To test the energy crisis model further, mice were given creatine, a bioenergetic compound that enhances the formation of ATP. Both control and knockout mice that were fed creatine showed increased axon regrowth following injury compared to mice fed saline instead. More robust nerve regrowth was seen in the knockout mice that got the creatine. Sheng also points out that these findings, while promising, are limited by the need to genetically manipulate mice.

Mice that lack Syntaphilin show long-term effects on regeneration, while creatine alone produces only modest regeneration. Future research is required to develop therapeutic compounds that are more effective in entering the nervous system and increasing energy production for possible treatment of traumatic brain and spinal cord injury.
