Spinal Cord Injury Recovery Improves with Drug Discovery

Scientists looking at potential pharmaceuticals to help people recover from spinal cord injuries have discovered a promising path to new treatments.

Researchers investigated over 1,000 possible medications and discovered that an already available one, cimetidine, boosted spinal healing in zebrafish.

When tested in spine-injured animals, the medication also improved mobility recovery and reduced the extent of spinal cord damage.

Experts claim the findings, which have been published in the journal Theranostics, give fresh light on the biochemical mechanisms involved in spinal cord injury rehabilitation.

Sudden strikes on the spinal cord, such as those induced by a car collision, can result in permanent injury.

Inflammation generated by an overreaction of the body’s immune system, which normally protects against infections, can make healing inefficient.

Anti-inflammatory drugs that decrease the entire immune response also block immunological cells that facilitate healing.

Multiple medications were examined in zebrafish larvae for their capacity to reduce excessive inflammation during an immunological response in a study headed by the University of Edinburgh.

Cimetidine works by helping to manage histamine levels in the body, which is a substance secreted by the immune system that is implicated in inflammatory reactions, according to researchers.

The findings allowed the researchers to identify a unique signaling route that moderates the immune response after spinal damage to aid in recovery.

Other medications that function in a similar way, according to experts, could be studied for their ability to aid recovery from spinal injury. However, they warn that further research is needed to explore their impact in human clinical trials.

According to the researchers, the study demonstrates the utility of zebrafish in the drug discovery process.

The research team included experts from the University of Edinburgh, the McGill University Health Centre Research Institute, and Technische Universität Dresden.

The ability to screen a large number of drugs using the zebrafish model has revealed an important target for future research into spinal cord repair. Our findings open the door to potential new treatments that can moderate inflammation and improve recovery from spinal injury,” said Professor Catherina Becker
