New Gene Therapy Can Restore Hand Function after Spinal Cord Injury

New gene therapy can possibly offer assistance to individuals with spinal cord wounds to re-learn skilled hand movements, reports a new study. The discoveries of the study are published in the journal Brain. People with spinal line damage frequently lose the capacity to perform ordinary activities that require coordinated hand developments such as writing, holding a toothbrush or picking up a drink. ‘New gene therapy can restore hand work after spinal cord harm by causing cells to deliver a chemical called chondroitinase which can break down the scar tissue and permit networks of nerve cells to regenerate.’

In the study, the researchers tried the modern gene treatment on rats for regenerating harmed tissue in the spinal cord that can be switched on and off employing a common antibiotic. "Gene therapy provides a way of treating expansive zones of the spinal cord with only one injection, and with the switch, we can presently turn the gene off when it is now not required," Researchers added.

After a traumatic spinal injury, thick scar tissue forms which prevent new connections being made between nerve cells. The gene therapy causes cells to deliver a chemical called chondroitinase which can break down the scar tissue and permit systems of nerve cells to regenerate.

The researchers gave the gene therapy to rats with spinal injuries that closely imitated the kind of human spinal injuries that happen after traumatic impacts such as car crashes or falls. "We found that when the gene therapy was switched on for two months, the rats were able to precisely reach and grasp sugar pellets," explained by researchers. "We moreover found a sensational increase in activity within the spinal cord of the rats, recommending that new connections had been made within the networks of nerve cells," she noted.

However, the researchers had to overcome an issue with the immune system recognizing and expelling the quality switch mechanism. To get around this, they added a "stealth quality" which hides the gene switch from the immune system. The gene therapy isn't however prepared for human trials, the researchers said.
