Avian influenza virus in mammals spreads beyond the site of infection to other organ systems
Researchers at Erasmus Medical Center have demonstrated systemic spread of avian influenza virus in cats infected by respiratory, digestive, and cat-to-cat contact. view more (2006-01-16)
Travel ban could reduce spread of SARS or other infectious diseases
Restricting travel could help reduce the spread of infections like SARS by more than 50%. In a study published today in the open access journal BMC Medicine, Swedish researchers simulated infection scenarios and tested the impact of travel restrictions on the spread of infection. view more (2006-12-14)
Fruit fly gene study could yield new flu treatments
As they design new drugs to fight off influenza, scientists may not need to attack the virus directly. Instead, they may be able to stave off infection by targeting one of more than 100 proteins inside host cells on which the virus depends. view more (2008-07-10)
Genetic vaccine promising against chronic hepatitis C
A potential vaccine candidate against chronic hepatitis C (HCV) infections is presented in a thesis from Karolinska Institutet. The new genetic vaccine can activate immune responses that are needed to clear HCV, a disease that today is difficult to treat effectively. The hepatitis C virus (HCV) is a major cause of chronic liver disease worldwide.... view more... (2004-06-07)
Timely Antiretroviral Therapy Essential For Best Prognosis In People With HIV-1 Infection (p 119)
Authors of an international study in this week's issue of THE LANCET highlight how timely treatment with highly-active antiretroviral therapy (HAART) can substantially improve the three-year prognosis for people with HIV-1 infection. HAART became widespread in more-developed countries in 1996. However, there is insufficient data from individual... view more... (2002-07-10)
Study first to show that RNA interference can facilitate vaccine development
Pharmaceutical companies and universities are racing to develop drugs that use the gene silencing mechanism known as RNA interference to treat a host of diseases. view more (2008-12-11)
Hoping for a fluorescent basket case
Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem. view more (2009-11-13)
ERADICATION OF GASTRIC BACTERIAL INFECTION COULD ALLEVIATE HEREDITARY OEDEMATOUS DISORDER (p 1695)
The eradication of the gastric bacterial infection Helicobacter pylori could play an important role in improving symptoms for people who have a genetic disorder known as hereditary angioneurotic oedema (HAO), conclude authors of a research letter in this week's issue of THE LANCET. view more (2001-11-14)
Features of replication suggest viruses have common themes, vulnerabilities
A study of the reproductive apparatus of a model virus is bolstering the idea that broad classes of viruses - including those that cause important human diseases such as AIDS, SARS and hepatitis C - have features in common that could eventually make them vulnerable to broad-spectrum antiviral agents. view more (2007-08-14)
Evolutionary 'battle scars' identify enhanced anti-viral activity
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center. view more (2008-01-25)
New gene silencing therapy for cervical cancer
Researchers at The University of Queensland's (UQ) Centre for Immunology and Cancer Research (CICR), based at the Princess Alexandra Hospital, have pioneered a new approach for the treatment of cervical cancer. view more (2005-11-17)
Yale study shows why cigarette smoke makes flu, other viral infections worse
A new study by researchers at Yale School of Medicine could explain why the cold and flu virus symptoms that are often mild and transient in non-smokers can seriously sicken smokers. Published in the Journal of Clinical Investigation, the study also identified the mechanism by which viruses and cigarette smoke interact to increase lung... view more... (2008-07-25)
Brown Researchers Make Major Signal Transduction Discovery
The chemical process known as acetylation plays a central role in cytokine receptor signal transduction - a fundamental biochemical cascade inside cells that controls the activity of antiviral and tumor-suppressing genes. view more (2007-10-05)
Reconstructed 1918 influenza virus induces immune response that fails to protect
An analysis of mice infected with the reconstructed 1918 influenza virus has revealed that although the infection triggered a very strong immune system response, the response failed to protect the animals from severe lung disease and death. view more (2006-09-28)
Hepatitis C complicated by morphine withdrawal
Researchers at the University of Pennsylvania have demonstrated that morphine withdrawal complicates hepatitis C by suppressing IFN-alpha-mediated immunity and enhancing virus replication. view more (2005-10-31)
Viral genetic differences are possible key to HIV dementia
The study of 18 HIV-positive subjects shows that HIV in the brain and central nervous system is genetically different from HIV that lives in the blood and peripheral tissues. view more (2006-07-26)
MRSA deaths on the rise
Infections due to MRSA seem to be an increasing cause of death in England and Wales, concludes a study in this week’s BMJ. view more (2002-12-11)
Tuberculosis Still a Risk for Patients Receiving HIV Drugs
People taking highly active antiretroviral therapy (HAART) for HIV infection remain susceptible to tuberculosis, though the risk is lower than for HIV-infected patients not on HAART. view more (2005-11-14)
Moving gene therapy forward with mobile DNA
Gene therapy is the introduction of genetic material into a patient's cells resulting in a cure or a therapeutic effect. In recent years, it has been shown that gene therapy is a promising technology to treat or even cure several fatal diseases for which there is no attractive alternative therapy. view more (2009-05-04)
HIV dearms protective protein in cells
The AIDS-causing HIV specifically counteracts the mechanisms of human cells that protect these against viral infections -- a special viral protein marks protective cellular proteins for their rapid destruction and thus diminishes the cell's supply. view more (2009-04-16)
