Genes to be ’flipped’ for drug-free treatment

10.05.2004


The body’s own defences could be programmed to attack disease to order if two University of Leeds’ scientists succeed in proving their innovative theory.


Dr Graham Cook and Dr Erica de Wynter from the Molecular Medicine Unit, University of Leeds



Dr Graham Cook and Dr Erica de Wynter from the Molecular Medicine Unit have secured £125,000 to investigate the unique way antibody genes are assembled and how they can be harnessed to fight disease.

Scientists don’t often get funding for research where there is no preliminary data or background information but the pair have been funded by the Wellcome Trust’s Showcase scheme to research new ways to repair damaged immune systems.


Their research into ‘flipping genes therapy’ met the Trust’s criterion of being ‘speculative, novel, adventurous, innovative’.

Dr Cook said antibodies can be made to respond to every kind of pathogen. “Antibodies are created by taking bits of genes and reassembling them into different combinations, like a giant Lego set. If we can understand the mechanism by which genes are ‘flipped’ in this way, we can insert genes for the body to naturally rearrange, delivering treatments directly to the immune system.”

If their idea works, it could open the door to new therapies for treating immune-deficiency disorders and even provide a treatment for cancers of the immune system, by adding genes to make the cancerous cells die.

“The benefit of this kind of treatment is that it would use the cell’s natural mechanism to help fight disease,” said Dr de Wynter. “Our body uses this system to produce diversity, an insurance system against the ever changing pathogens it has to fight. Our problem is we want to specify the mechanism to create just one antibody, and while we believe it can work, we’ve now got to prove it. We think we can prove our idea is possible in the next two years.”

Im Focus: Why we need erasable MRI scans

New technology could allow an MRI contrast agent to 'blink off,' helping doctors diagnose disease

Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is...

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
