Possible Hepatitis C vaccineSeptember 04, 2007Hepatitis C Virus (HCV) infects up to 500,000 people in the UK alone, many of the infections going undiagnosed. It is the single biggest cause of people requiring a liver transplant in Britain. Now scientists have found monoclonal antibodies which may make a successful vaccine a reality, researchers heard today (Tuesday 4 September 2007) at the Society for General Microbiology's 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 September 2007. Hepatitis treatment is expensive and only successful in half of patients. Untreated or unresponsive patients can go on to develop cirrhosis of the liver, with life affecting consequences or the need for a transplant. In a collaborative effort with groups across Europe and the USA, scientists from Nottingham University have recently identified antibodies that can successfully prevent infection with many diverse strains of Hepatitis C virus in laboratory models.
"The clinical potential of this work cannot be overstated. Historically, successful vaccines against viruses have required the production of antibodies, and this is likely to be the case for Hepatitis C virus", says Dr Alexander Tarr from the Virus Research Group at the University of Nottingham. "Identifying regions of the virus that are able to induce broadly reactive neutralising antibodies is a significant milestone in the development of a HCV vaccine, which will have distinct healthcare benefits for hepatitis sufferers, and could also help us design vaccines for other chronic viral diseases such as HIV". Hepatitis C virus infects 180 million people worldwide. Infection with the virus can lead to liver cancer, and is the most common reason for liver transplantation in both the UK and the USA. "We are also currently exploring the possibility of improving liver transplantation success rates by passively infusing people with these antibodies" says Dr Tarr. "We are also using the information gained by identifying and characterising the antibody responses to Hepatitis C virus to design new ways of making vaccine candidates. If the antibodies we have discovered can be reproduced by vaccination, control of the disease might be possible". Society for General Microbiology | |||||||||||||||||||||

To protect against liver disease, body puts cells 'under arrest' A stable form of cell-cycle arrest known to offer potent protection against cancer also limits liver fibrosis, a condition characterized by an excess of fibrous tissue, according to a new report in the August 22nd Cell, a Cell Press publication. Senescence in liver cells is found by CSHL scientists to help limit acute tissue damage Although post-reproductive life in humans is often associated with decline and a loss of powers, an analogous state in certain cells -- called senescence -- is proving to be one of ironic potency. Scientists at Cold Spring Harbor Laboratory (CSHL) today reported that a particular class of senescent liver cells orchestrates a sequence of events in living mice that can limit fibrosis, a natural response of the liver to acute damage. Trapping white blood cells proves novel strategy against chronic viral infections Seeing disease-fighting white blood cells vanish from the blood usually signals a weakened immune system. But preventing white blood cells' circulation by trapping them in the lymph nodes can help mice get rid of a chronic viral infection, researchers at Yerkes National Primate Research Center and the Emory Vaccine Center have found.

Early treatment is key to combating hepatitis C virus Canadian researchers have shown that patients who receive early treatment for Hepatitis C virus (HCV) within the first months following an infection, develop a rapid poly-functional immune response against HCV similar to when infection is erradicted spontaneously, according to a new study published in the Journal of Virology. International panel updates treatment guidelines for HIV infection An evaluation of recent data has led to an update in the guidelines and recommendations for antiretroviral treatment of adult human immunodeficiency virus (HIV) infection, according to an article in the August 6 issue of JAMA, a theme issue on HIV/AIDS. Imiquimod, an immune response modifier, is dependent on the OGF-OGFr signaling pathway Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the efficacy of imiquimod, a clinically important immune response modifier with potent antiviral and antitumor activity, is dependent on the Opioid Growth Factor (OGF)-OGF receptor (OGFr) axis for its action. Researchers disprove long-standing belief about HIV treatment Researchers at Wake Forest University Baptist Medical Center have disproved a long-standing clinical belief that the hepatitis C virus slows or stunts the immune system's ability to restore itself after HIV patients are treated with a combination of drugs known as the "cocktail."
