New host species for avian influenza identified
In a new study published online in the open-access journal PLoS Pathogens, Dr. Vincent J. Munster, of Erasmus Medical Center, Rotterdam, and colleagues identify new host species for avian influenza A virus (H5N1) and provide important information on the distinctions between the ecology and epidemiology of various global strains of the virus. view more (2007-05-11)
Einstein scientists treat cancer as an infectious disease -- with promising results
Researchers at the Albert Einstein College of Medicine of Yeshiva University have shown for the first time that cancers can be successfully treated by targeting the viruses that cause them. view more (2007-10-31)
Bird flu vaccine additive may stretch supply
Researchers have achieved an effective immune response to an avian influenza vaccine with doses as low as one-quarter of the norm when they added a chemical mixture known as MF59. view more (2006-09-26)
NIAID DNA vaccine for H5N1 avian influenza enters human trial
The first human trial of a DNA vaccine designed to prevent H5N1 avian influenza infection began on December 21, 2006, when the vaccine was administered to the first volunteer at the National Institutes of Health (NIH) Clinical Center in Bethesda, MD. view more (2007-01-05)
Mayo researchers discover HIV dependence on a human protein
Mayo Clinic virologists have discovered that a specific human protein is essential for HIV to integrate into the human genome. view more (2006-09-08)
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...

Study unveils how West Nile virus evades immune defenses, points to vaccine development
West Nile virus evades the body's immune defenses by blocking immune signaling by a protein receptor, a finding that could pave the way for a vaccine to protect against North American strains of the virus. view more (2006-10-05)
LIAI completes world's most comprehensive analysis on influenza virus data
Researchers from the La Jolla Institute for Allergy & Immunology (LIAI) announced today the results of a first of its kind study analyzing all published data worldwide on influenza A virus antibody and T cell epitopes. view more (2007-01-02)
Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development
o ignite a life-threatening infection in the body, a virus such as HIV invades body cells by first merging, or fusing, with the cell's outer membrane. Once inside the cell, the invading microbe's genetic material takes over, turning the 'host' cell into a factory to produce more copies of the virus, which then spill out to invade other cells in... view more...

Scientists isolate world's oldest recorded plant virus
A Japanese poem written by Empress Koken, in the summer of 752AD, is thought to be the world's first record of a plant virus. Scientists from the John Innes Centre in Norwich (JIC)(1) have today reported, for the first time, the isolation and characterisation of the plant virus (eupatorium yellow vein virus - EpYVV(2) that causes the spectacular... view more...

International study investigates early biology of HIV infection
In July 2005, the race to find a vaccine that would stem the worldwide rate of 13,000 new cases of HIV infection each day moved from competition among research institutions to a strategy of cooperation. view more (2006-05-02)
OHSU researchers discover possible HIV therapy in an animal study
Researchers have published a new study this week suggesting an important component of the immune system damaged by AIDS can possibly be replaced. view more (2006-06-09)
Earlier bites by uninfected mosquitoes boost West Nile deaths in lab mice
There's one more reason to try to avoid being bitten by mosquitoes, scientists have discovered: bites from mosquitoes that aren't infected by the West Nile virus may make the disease worse in people who acquire it later from West Nile-infected mosquitoes. view more (2007-11-16)
Influenza spreads readily in winter conditions
Low temperatures and relative humidities have been linked to the rapid spread of influenza in a new study by researchers, led by Dr. Peter Palese, from the Mount Sinai School of Medicine. The study, published in PLoS Pathogens, supports the theory of the seasonal flu. view more (2007-10-19)
New Vaccine Developed for Preventing 'Uncommon Cold' Virus
Common colds typically cause a week of sneezing, aches and pains and then fade away leaving only a sore nose and a few used sick days behind. But what if that cold turned out to be something more? view more (2009-02-03)
Two More Potential HIV Vaccines
Despite long-term researchers' efforts, efficient human immunodeficienct virus (HIV) vaccine has not been created yet. However, researchers are not giving up their attempts. Russian biologists are now proposing two more vaccine options based on DNA that encodes human immunodeficienct virus proteins. Experience proves that traditional ways of... view more... (2004-05-17)
New research predicts US entry of H5N1 avian influenza
Scientists at the Consortium for Conservation Medicine (CCM), the Royal Society for the Protection of Birds, and the Smithsonian Institution's National Zoo report that H5N1 avian influenza is most likely to be introduced to countries in the Western Hemisphere through infected poultry trade. view more (2006-12-05)
Researchers identify key step bird flu virus takes to spread readily in humans
Since it first appeared in Hong Kong in 1997, the H5N1 avian flu virus has been slowly evolving into a pathogen better equipped to infect humans. The final form of the virus, biomedical researchers fear, will be a highly pathogenic strain of influenza that spreads easily among humans. view more (2007-10-05)
Three-in-one virus killer prevents common, often fatal infections
A novel combination therapy drastically reduces the infection rate of three viruses - and risk of death - in transplant patients with compromised immune systems. view more (2006-10-27)
Enzyme inhibitors block replication Of SARS virus
Researchers have known since 2003 that a site on the virus is responsible for mediating proteases that allow the virus to replicate. Since then researchers have been testing protease inhibitors to lock up this site, known as SARS 3CLpro, and effectively stop the virus from infecting additional cells in the body. view more (2006-03-28)
