Researchers have made a significant advance in the understanding of the hepatitis C virus (HCV) by identifying new genetic factors associated with clearing the virus spontaneously without the necessity for additional treatment. Their findings are set out in a paper published in Science magazine today (6 August 2004).
Hepatitis C virus infects the liver and leads to serious permanent liver damage. The infection affects about 170 million people worldwide and up to 500,000 people in the UK. Most people who come into contact with HCV contract a long-term or chronic infection and, as a consequence, run a significant risk of liver failure - necessitating liver transplantation - or liver cancer.
The new multi-centre study was jointly led by researchers from the University of Southamptons School of Medicine, the National Genetics Institute, USA, and the Johns Hopkins Hospital, USA. The findings demonstrate that natural killer (NK) cells provide a central defence against HCV infection and that this defence is mediated by specific inhibitory receptors expressed on NK cells and the partners or ligands for these receptors on liver cells.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
