One of the world’s leading researchers into spinal cord injuries says China could hold the key to a cure that he has been searching for since he met late actor Christopher Reeve in the 1990s.
US-based Doctor Wise Young first used the word “cure” in relation to his work after a conversation with Reeve, the Superman hero who became a quadriplegic in an equestrian accident in 1995.

The cancer drug Taxol has the potential to assist nerve regeneration following a spinal cord injury, according to researchers.
The study, which has been published on the Sciencemag website, details how the drug can help in the regeneration of damaged cells in the central nervous system following a spinal cord injury.

There have been several recent developments in the potential treatment of spinal cord injury. A group of researchers showed they were able to enhance the regeneration of nerve connections after spinal cord injury by deleting an enzyme called PTEN. The enzyme controls a molecular pathway called mTOR that is a key regulator of cell growth. During development, when nerve growth and connections occur, PTEN activity is low, allowing cell growth. When growth is completed, PTEN is turned on to inhibit cell growth. Controlled stimulation of cell growth is important for tissue regeneration. The scientists disabled PTEN in mice and were able to achieve nerve growth past a spinal cord lesion. The study published in Nature Neuroscience points to possible strategies to encourage a damaged spinal cord to sprout new neuron growth for repair.

Deletion of key gene could help nerve fibers regenerate, researchers say
Deleting a gene that suppresses natural growth factors enables regeneration of injured nerve fibers (axons) in mice, a new study shows.
The finding may lead to new treatments for people with brain and spinal cord injuries.

Scientists guide axons to re-form nerve connections in rats
In a finding that is a major advance in spinal cord injury research, U.S. scientists report that regenerating axons can be guided to their correct targets where they can re-form connections after spinal cord injury.
