Publications 2013: Part 2


Zur Übersicht

30 research projects were published in 2013. The publications show the advancements done in all research fields related to spinal cord injury.

Close collaboration between the scientists and the discussion of their results are essential for optimal research progress. To share their results, scientists publish their work in special interest journals. Please find below the latest publications of research projects that have been funded by Wings for Life, sorted by their key area of research.

Secondary damage (protection of intact cells)
These findings based on multiple sclerosis give new hints on neuroinflammation resolution that is associated with secondary damage in spinal cord injury.

  • Prüss H, Rosche B, Sullivan AB, Brommer B, Wengert O, Gronert K, Schwab JM. Proresolution lipid mediators in multiple sclerosis - differential, disease severity-dependent synthesis - a clinical pilot trial. PLoS One.


Plasticity (eliminating growth inhibitors)
The following publication gives insights in the complex matrix that is found between the cells, exactly where neurons are supposed to regenerate and get the maximum regrowth inhibition.

  • Dick G, Tan CL, Alves JN, Ehlert EM, Miller GM, Hsieh-Wilson LC, Sugahara K, Oosterhof A, van Kuppevelt TH, Verhaagen J, Fawcett JW, Kwok JC Semaphorin 3A Binds to the Perineuronal Nets via Chondroitin Sulfate Type E Motifs in Rodent Brains. J Biol Chem.


Regeneration (nerve growth)
While the first two publications explore the importance of intracellular signaling to promote neuronal regeneration, the publication of Dr. Oudega tests a new kind of biomaterial to be transplanted at the injury site. Dr. Strittmatter demonstrated that a particular electrical stimulation, associated with exercise could promote functional restoration. The article of Dr. Fainzilber proved the importance of intracellular local protein synthesis for developing and regenerating axons. Finally, the last two publications (Dr. Fouad and Dr. Olson) explored the effect of combinatorial treatments for promoting nerve growth.

Neural reconstruction (introduction of new cells)
The group of Dr. Fehlings found a way to increase the clinical potential of induced pluripotent stem cells (iPSCs), a category of stem cells that may solve many issues common to cell based therapy strategies like immune response and cell availability. The last two publications focus on the effect of stem cell grafting on functional recovery and on the interaction of stem cells with the inflammatory tissue reaction.

Remyelination (insulation of nerve fibres)
This article from the team of Dr. Barnett proves that only a particular subpopulation of mesenchymal stem cells is able to restore myelination of neurons.

  • Lindsay SL, Johnstone SA, Mountford JC, Sheikh S, Allan DB, Clark L, Barnett SC. Human mesenchymal stem cells isolated from olfactory biopsies but not bone enhance CNS myelination in vitro. Glia.


Imaging
The first publication proves that the usage of imaging techniques as outcome predictive tool can be successfully achieved. The two publications in Neuroimage finally give an overview of the advancements of spinal cord imaging.

Compensation treatment
The following eleven publications can be divided in three categories. Most articles are reporting the benefits of particular rehabilitation techniques (electrical stimulation, etc.) on human locomotor activity.

Bioinformatics    
By its content the following article belongs to a particular category. The research of Dr. Ferguson has an application on all fields related to spinal cord injury. This in silico analysis of preclinical outcome data from 10 years of basic research on spinal cord injury gave outstanding results which will have, on the long run, a strong impact on the whole spinal cord injury field. Their particular approach provides indeed a roadmap for translating therapies from basic to clinical research.
