Gene therapy reverses rat’s paralysis at King’s College London

Researchers at King’s have shown that rats with spinal cord injuries can re-learn skilled hand movements after being treated with a gene therapy that could be switched on and off using a common antibiotic.

Researchers at King’s College London and the Netherlands Institute for Neuroscience have shown that rats with spinal cord injuries can re-learn skilled hand movements after being treated with a gene therapy.

People with spinal cord injury often lose the ability to perform everyday actions that require coordinated hand movements, such as writing, holding a toothbrush or picking up a drink. Regaining hand function is the top priority for patients and would dramatically improve independence and quality of life.

The researchers had to overcome a problem with the immune system recognising and removing the gene switch mechanism. To get around this, the researchers worked with colleagues in the Netherlands to add a ‘stealth gene’ which hides the gene switch from the immune system.

Professor Joost Verhaagen at the Netherlands Institute for Neuroscience says: ‘The use of a stealth gene switch provides an important safeguard and is an encouraging step toward an effective gene therapy for spinal cord injury. This is the first time a gene therapy with a stealth on/off switch has been shown to work in animals.’

    The gene therapy is not yet ready for human trials. While the ability to switch a therapeutic gene off provides a safeguard, the researchers found a small amount of the gene remained active even when switched off. They are now working on shutting the gene down completely and moving towards trials in larger species.

    That’s great!
    Keep up the good work and find a cure for spinal cord injury.
    When it is ready I like to sign up for the clinical trial.
