Body's anti-HIV drug explained
Humans have a built-in weapon against HIV, but until recently no one knew how to unlock its potential. view more (2008-10-13)
Cranberries can treat herpes
Alpine cranberries have significant biological activity that can help to combat herpes virus type II (HSV-2) infection, one of the most common viral infections in humans, writes Emma Dorey in Chemistry & Industry. view more (2004-10-15)
Mutations within a conservative region of HCV affects the therapy
At least 200 million individuals are currently infected with hepatitis C virus (HCV) worldwide. Approximately 30%-50% of patients respond to interferon/ribavirin combination therapy. view more (2009-03-31)
Modified crops reveal hidden cost of resistance
Genetically modified squash plants that are resistant to a debilitating viral disease become more vulnerable to a fatal bacterial infection, according to biologists. view more (2009-10-27)
New West Nile and Japanese encephalitis vaccines produced
University of Texas Medical Branch at Galveston researchers have developed new vaccines to protect against West Nile and Japanese encephalitis viruses. The investigators created the vaccines using an innovative technique that they believe could also enable the development of new vaccines against other diseases, such as yellow fever and dengue... view more...

Blocking effects of viral infections may prevent asthma in young children
Babies who get severe respiratory viral infections are much more likely to suffer from asthma as they get older. view more (2007-11-08)
Uncovering the Achilles' heel of the HIV-1 envelope
New structural details illustrate how a promising class of antibodies may block human immunodeficiency virus (HIV)-1 infection and reveal valuable clues for design of an effective HIV-1 vaccine. view more (2008-01-14)
Details of the life cycle of SARS coronavirus
A team of scientists studying Severe Acute Respiratory Syndrome (SARS) has, for the first time, described how the SARS virus manufactures several of the materials required for making copies of itself. "It is essential, when you are looking for ways to stop a disease, that you know exactly how viruses make copies of themselves and... view more... (2003-07-08)
Adprotech and Wyeth Collaborate on Vaccine Technology
14 February 2001, Cambridge, UK ………….. Adprotech Limited, the advanced protein engineering company and Wyeth Lederle (WL), the vaccine unit of Wyeth-Ayerst Laboratories, the pharmaceutical division of American Home Products Corporation (NYSE: AHP) have signed a research agreement to evaluate Adprotech’s... view more...

Viruses Evolve To Play By Host Rules, According to University of Pennsylvania Researchers
Biologists at the University of Pennsylvania and Harvard University have examined the complete genomes of viruses that infect the bacteria E. coli, P. aeruginosa and L. lactis and have found that many of these viral genomes exhibit codon bias, the tendency to preferentially encode a protein with a particular spelling. view more (2008-03-04)
Yale study explains complex infection fighting mechanism
Yale School of Medicine researchers report in Nature Immunology how infection fighting mechanisms in the body can distinguish between a virus and the healthy body, shedding new light on auto immune disorders. view more (2006-01-11)
New technique kills cancer virus without harming healthy cells
Major breakthrough could lead to successful treatment of viral cancers, without side-effects. Yorkshire Cancer Research funded researchers at the University of York have made a major cancer breakthrough. Using a new technique called RNA interference, they have successfully killed human cervical cancer cells grown in culture without causing damage... view more... (2002-09-03)
Molecule that suppresses immune response under study in type 1 diabetes
The idea is to teach the immune system of children at high risk for type 1 diabetes not to attack the insulin-producing cells of the pancreas. view more (2009-02-05)
Molecular switch may turn off immune cells that target HIV
One of the primary mysteries of the AIDS epidemic - why the immune system is unable to control HIV infection - may have been solved by an international research collaborative. view more (2006-08-21)
Study reveals a 'missing link' in immune response to disease
The immune system's T cells have the unique responsibilities of being both jury and executioner. They examine other cells for signs of disease, including cancers or infections, and, if such evidence is found, rid them from the body. Precisely how T cells shift so swiftly from one role to another, however, has been a mystery. view more (2009-11-03)
How 'memory' T cells curb the spread of viruses throughout the body
A scientific discovery by Fox Chase Cancer Center researchers helps explain how "memory" T cells protect the body from viral diseases. view more (2007-06-19)
Immune exhaustion in HIV infection
As HIV disease progresses in a person infected with the HIV virus, a group of cells in the immune system, the CD8+ T lymphocytes, become "exhausted," losing many of their abilities to kill other cells infected by the virus. view more (2008-05-06)
Scientists learn structure of enzyme in unusual virus
Biologists have determined the three-dimensional structure of an unusual viral enzyme that is required in the assembly of new viruses. view more (2007-09-18)
A new step towards an AIDS vaccine
Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body. view more (2005-10-14)
The origin of HIV-1 New clarification from an epidemiological study in central Africa
An enormous variety of strains of HIV-1 are circulating in the Democratic Republic of Congo (DRC, ex-Zaire). The diversity is much higher than that observed in other African countries and as great as that encountered in the world as a whole. This is the main finding of a wide-ranging epidemiological study undertaken by an IRD research unit (UR 036... view more... (2001-04-25)
