Scientists learn more about how viruses reproduce, spread
Biochemists at Wake Forest University School of Medicine have made a surprising discovery about the inner workings of a powerful virus - a discovery that they hope could one day lead to better vaccines or anti-virus medications. view more (2006-04-07)
Immunologists find better way to boost the immune system
Immunologists have discovered how to manipulate the immune system to increase its power and protect the body from successive viral infections. view more (2008-01-23)
Avian flu in perspective
An article by Robert Belshe, M.D., of Saint Louis University School of Medicine in this week's New England Journal of Medicine reviews recent "spectacular achievements of contemporary molecular biology" that hold great importance as the world prepares for a possible flu pandemic. view more (2005-11-28)
Analysis of Spanish flu cases in 1918-1920 suggests transfusions might help in bird flu pandemic
Transfusions with blood products taken from people who had recovered from Spanish influenza may have reduced risk for death and improved symptoms of hospitalized patients who contracted Spanish influenza complicated by pneumonia. Early treatment was superior to later treatment. view more (2006-08-30)
Study: Harmless virus kills some cancers
Six days is all it takes for a common, non-disease-causing virus to kill cervical, breast, prostate and squamous cell cancer cells in laboratory cultures, according to Penn State College of Medicine researchers. view more (2005-06-22)
Whitefly spreads emerging plant viruses
A tiny whitefly is responsible for spreading a group of plant viruses that cause devastating disease on food, fiber, and ornamental crops, say plant pathologists with The American Phytopathological Society (APS). view more (2007-01-19)
Minor mutations in avian flu virus increase chances of human infection
The H5N1 avian influenza virus, commonly known as "bird flu," is a highly contagious and deadly disease in poultry. view more (2006-03-20)
Immune response to HIV in the brain
Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus. view more (2006-04-28)
'Bird flu' infections in humans prompt new investigation at Saint Louis University
When a new strain of flu infects people, the infection can spread around the world quickly. This is what could potentially happen with some new human flu viruses that come from bird flu viruses. view more (2006-01-17)
Contagious equine flu virus infecting dogs across U.S. is isolated by Cornell researchers
A Cornell University virologist has isolated a highly contagious equine flu virus that is spreading a sometimes-fatal respiratory flu among dogs, and is responsible for a major dog-flu outbreak in New York state. view more (2005-09-29)
Clinical trials with immunotherapy for breast and colorectal cancer
Researchers at Mount Sinai School of Medicine are conducting clinical trials on a unique approach to enhance the immune system in patients with breast or colorectal cancer. view more (2005-11-01)
St. Jude test of bird flu vaccine proves successful
A commercially developed vaccine has successfully protected mice and ferrets against a highly lethal avian influenza virus, according to the investigator who led the study at St. Jude Children's Research Hospital. view more (2006-05-03)
Secrets to antibody's success against West Nile Virus surprise scientists
A monoclonal antibody that can effectively treat mice infected with West Nile virus has an intriguing secret: Contrary to scientists' expectations, it does not block the virus's ability to attach to host cells. view more (2005-09-29)
Threat of avian influenza pandemic grows, but people can take precautions
An editorial in the December issue of Mayo Clinic Proceedings paints a picture of a world population very susceptible to an avian flu pandemic, but also offers suggestions to physicians that could help answer questions presented by patients who may be feeling anxious about the "bird flu." view more (2005-12-06)
Monkeypox mystery: New research may explain why 2003 outbreak in the US wasn't deadly
An outbreak of 72 cases of monkeypox in the United States during the summer of 2003 didn't produce a single fatality, even though the disease usually kills 10 percent of those infected. view more (2005-07-18)
Genetically engineered mosquitoes show resistance to dengue fever virus
Researchers have successfully created a genetically engineered mosquito that shows a high level of resistance against the most prevalent type of dengue fever virus, providing a powerful weapon against a disease that infects 50 million people each year. view more (2006-03-09)
Genome circularization and RNA virus replication
As featured on the cover of the August 15th issue of G&D, an Argentinian research team, led by Dr. Andrea Gamarnik, report on their recent discovery of a novel mechanism of dengue virus replication. view more (2006-08-01)
Ocean virus identified in human blood samples
A virus of ocean origin that can cause a range of diseases in several animal species has been found in human blood samples. view more (2006-03-24)
Dengue Virus Reveals Its Circular Secret
The first step in the transmission of mosquito-borne viruses is no mystery: it's the pesky insect's bite that allows the virus to enter its victim's bloodstream. But for some of the most dangerous insect-borne viruses, details of what happens next have been unclear. view more (2006-08-02)
Penn researchers discover key to how SARS virus infects cells
Researchers from the University of Pennsylvania School of Medicine have found that inhibitors of an enzyme called cathepsin L prevent the SARS (severe acute respiratory syndrome) virus from entering target cells. SARS is caused by an emergent coronavirus. view more (2005-08-02)
