Key areas of research

Secondary damage (protection of intact cells)
A spinal cord injury is followed by a massive breakdown of neuronal and supporting cells (known as glial cells) around the site of injury. This area of research aims to prevent the secondary damage and therefore preserve more functions for those affected.

Spinal cord injury is accompanied by the release of substances that block the renewed growth of nerves. The aim is to find, analyse and eliminate these substances known as natural growth inhibitors. In the last few years major advancements have been made in this area of research. Additionally it is important to understand the mechanisms underlying the reorganization of the spinal circuitry and interconnections.

When an adult nerve fibre in the central nervous system is completely severed, its ability to regrow is very restricted. Wings for Life funds projects that searching for ways to stimulate nerves to regenerate and regrow.

Neural reconstruction
This area of research aims to replace destroyed tissue by the transplantation of cells and/or biomaterials. Very promising approaches focus on the use of stem cells or prosthetic biomaterials to repair injured spinal cord tissue.

Remyelination (insulation of nerve fibres)
Injured nerve fibres lose their protective cover, known as the myelin sheath. Like an electric wire that loses its insulation, the demyelinated nerve fibres lose their ability to properly transmit signals. Wings for Life supports research that aims to restore this protective sheath (remyelination) and to improve nerve cell function.

A number of preclinical studies report positive results, like enhanced growth of nerve fibres and a better behavioral outcome. However, we currently lack imaging techniques to monitor the changes in the spinal cord tissue in vivo. This fact makes it difficult to elucidate the underlying mechanisms and to compare the results. Wings for Life is doing pioneering work in this field by funding studies aiming to develop better in vivo imaging techniques.

Rehabilitation/Compensatory treatment
Research projects in this area are not focused on direct restoration of the injured nervous system, but on the improvement of the functional deficits and thus improving the affected individual's quality of life, such as bladder function and the treatment of neuropathic pain, and at developing new rehabilitation methods, to name but a few examples.

Scientific knowledge

Progress is being made


In the last few years Wings for Life has been able to initiate a large number of promising projects, especially in the fields of basic and preclinical research. The next major step will be to translate these into clinical studies that ultimately lead to treatments for spinal cord injury.

Due to the complex nature of paralysis, a combination of various therapeutic approaches seems to offer the best chances of success. Major approaches currently under development include:

Reducing secondary damage
An advanced area of research relates to treatment options for patients in the early stages after a spinal cord injury. Several pharmacological interventions are currently tested in clinical phase I/II studies, for example Riluzole or Minocycline. These pharmacological therapeutics are reported to reduce additional tissue damage resulting in a better functional recovery of the patients. A recently published study with Minocycline performed at the University of Calgary showed a better outcome in motor functions.

Eliminating growth inhibitors
After a spinal cord injury, there is a lot of cell debris in the spinal tissue which can significantly limit the regeneration of nerves. Various types of cell debris send signals to nerve fibres saying: “Stop. This is a dead end.” For example, one of the stop signs responsible is known to be the protein Nogo. A substance to counteract the effect of Nogo is already being tested in a clinical study for patients in the early stages after a spinal cord injury (Prof. Dr. Martin Schwab, Nogo antibody study by Novartis). In a model for those living with a spinal cord injury as an ongoing condition, Prof. Dr. Stephen M. Strittmatter and his research team have succeeded in blocking several of these stop signs simultaneously and as a result saw marked functional improvements.

Axon growth
Nerve cells in the central nervous system lose most of their ability to regenerate as they mature. Therefore, researchers focus on “switches” that would overcome this challenge. For example, the research group working with Zhigang He at the Children’s Hospital in Harvard has identified that it is possible to trigger the regeneration of axons to a previously unknown extent by eliminating two molecular stop signs within the nerve cell (PTEN and SOCS3).

Cell-based approaches
Based on successful preclinical projects, there is a lot of hope surrounding therapies with stem cells as these are able to form tissue scaffolds, release growth factors, form new circuits and promote the regrowth of the protective myelin sheath. There are still important questions surrounding which cells are compatible for transplantation into the injured spinal cord. Answers to these questions are being sought through a first European clinical study (phase I/II) using neural human precursor/stem cells at the University Clinic Balgrist under the direction of Prof. Dr. Armin Curt.

These examples of scientific results and developments provide strong hope that treatment options are closer than they have ever been. However, intensive research work will be needed before a breakthrough in human medicine can be achieved.
