Visualizing virus replication in 3 dimensions
Dengue fever is the most common infectious disease transmitted by mosquitoes - some 100 million people around the world are infected. Researchers at the Hygiene Institute at Heidelberg University Hospital were the first to present a three-dimensional model of the location in the human cell where the virus is reproduced. view more (2009-05-08)
UCLA scientists identify how key protein keeps chronic infection in check
Why is the immune system able to fight off some viruses but not others, leading to chronic, life-threatening infections like HIV and hepatitis C? view more (2009-05-08)
Swine flu genes dissimilar to past pandemics
Some genetic markers of influenza infection severity have been identified from past outbreaks. Researchers have failed to find most of these markers, described in the open access journal BMC Microbiology, in samples of the current swine-flu strain. view more (2009-05-07)
Novel antibody prevents infection by hepatitis C virus
Taking aim at a leading cause of liver failure in the United States, a team of scientists at the Massachusetts Biologic Laboratories (MBL) of the University of Massachusetts Medical School (UMMS) has developed a human monoclonal antibody that neutralizes the Hepatitis C virus (HCV). view more (2009-05-06)
Does new swine flu virus kill by causing a 'cytokine storm'?
The swine flu outbreak that began in Mexico and continues to spread around the globe may be particularly dangerous for young, otherwise healthy adults because it contains genetic components of the H5N1 avian influenza virus, which can induce a "cytokine storm," in which a patient's hyper-activated immune system causes potentially fatal... view more...

Scientists learn why the flu may turn deadly
As the swine flu continues its global spread, researchers from the Children's Hospital of Philadelphia, Pennsylvania, have discovered important clues about why influenza is more severe in some people than it is in others. view more (2009-05-05)
Virginia Tech virologist developing more potent vaccine technology
Virginia Tech virologist Chris Roberts' goal is to develop a platform for a flu vaccine that allows rapid modifications to meet new strains of flu. view more (2009-05-05)
Cancer-causing virus associated with higher risk of new HIV infection
Infection with anal human papillomavirus (HPV), a virus that can cause anal and cervical cancers, is associated with a higher risk of new HIV infection in previously HIV-negative men who have sex with men (MSM), according to new UCSF research. view more (2009-05-01)
Avian Flu Research Sheds Light on Swine Flu Outbreak
A recent study by University of Maryland researchers examines the mechanisms underlying transmission of combined avian-human viruses and illustrates how virus outbreaks like that of the current swine flu come about. view more (2009-04-30)
Findings uncover new details about mysterious mimivirus
An international team of researchers has determined key structural features of the largest known virus, findings that could help scientists studying how the simplest life evolved and whether the unusual virus causes any human diseases. view more (2009-04-29)
Matrix protein key to fighting viruses
Researchers from Durham University's Centre for Bioactive Chemistry are developing methods that show how proteins interact with cell membranes when a virus strikes. view more (2009-04-29)
The structure of a giant virus
The mimivirus is the largest virus known to scientists, about half of a micrometre (0.0005 millimeter) in diameter. It is more than 10 times larger than the virus that causes the common cold and - unlike other viruses - is large enough to be seen with a light microscope. view more (2009-04-28)
Scientist warns over pandemic flu vaccine 6-month time lag
New research published today (Monday April 27) from the University of Leicester and University Hospitals of Leicester NHS Trust warns of a six-month time lag before effective vaccines can be manufactured in the event of a pandemic flu outbreak. view more (2009-04-28)
Caltech scientists show why anti-HIV antibodies are ineffective at blocking infection
Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled. view more (2009-04-23)
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)
HIV handicaps itself to escape immune system pressure
People with the ability to stave off AIDS for years after initial infection by HIV have been called "long-term non-progressors" or "elite controllers." view more (2009-04-16)
Minimising the spread of deadly Hendra virus
Groundbreaking CSIRO research into how the deadly Hendra virus spreads promises to save the lives of both horses and humans in the future. view more (2009-04-15)
HIV pays a price for invisibility
Mutations that help HIV hide from the immune system undermine the virus's ability to replicate, show an international team of researchers in the April 13 issue of the Journal of Experimental Medicine. view more (2009-04-13)
Not just a long distance relationship: immune cells in skin fight off infection better than the rest
Scientists at the University of Melbourne have discovered the local action of immune cells in the skin, which could improve treatment of viral skin infections. view more (2009-04-08)
Has HIV Become More Virulent?
Damage to patients' immune systems is happening sooner now than it did at the beginning of the HIV epidemic, suggesting the virus has become more virulent. view more (2009-04-08)
