Research offers hope of new treatments for liver damage ‘plague’

06.01.2005


Millions of patients suffering from liver damage (cirrhosis) and failure may benefit from research by the Universities of Southampton and Edinburgh that could lead to new life-saving treatments. There is currently no cure for liver cirrhosis and a patient’s only hope of survival is to receive a liver transplant.

The Southampton scientists from the University’s Infection, Inflammation and Repair Division of the School of Medicine, in collaboration with colleagues from the University of Edinburgh and Cincinnati, USA have, for the first time, identified two separate populations of immune cells — macrophages — in the liver. One group of macrophages causes scarring to the liver, but the next wave of immune cells, produced only a few days later, change function to break down and reabsorb the scarring. These findings, published in the January edition of Journal of Clinical Investigation, will help doctors to understand the mechanisms by which the liver is damaged and repaired and may lead to future treatments.

Professor John Iredale of the University of Southampton said: ‘We are facing a huge increase in the numbers of patients with advanced liver fibrosis (scarring) and cirrhosis (end stage scarring of the liver). Currently we have no effective treatment for liver cirrhosis which is associated with internal bleeding, liver failure and the development of primary liver cancer. There is a huge imperative to develop new approaches to the treatment of liver scarring. Exciting insights such as these will inform the design of future therapies.’



Researcher Dr Jeremy Duffield of Edinburgh explained: ‘The links between the immune system, inflammation and scarring in the liver have not been well understood, and this has hindered progress in finding ways to prevent and repair liver damage. Now that we have shown how the macrophages work, we aim to find out how to create, activate and de-activate these cells to make them repair, rather than damage, liver tissue.’

He added: ‘Cirrhosis, commonly but not always caused by alcohol consumption, can lead to liver failure. At a time when outcomes for other diseases such as cancers and heart trouble have made dramatic gains, liver damage — described as the new plague of the 21st century — has yet to be understood and in turn to become treatable. More women in the UK now die of liver failure than do of cancer of the cervix.’

There has been a fourfold increase in the number of men aged 45–54 dying of cirrhosis since 1970 and a threefold increase in women of the same age group. Liver failure is also rapidly increasing in younger people with the deaths in the UK of 500 men and 300 women aged 25–44 in 2003.

Further research into macrophages is set to follow and scientists will explore the role of these immune-system cells in damage and repair to other organs, including the kidney.

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.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
