Expert dispels bird flu paranoia
The risk of human bird flu infection is small in Australia and people can still safely eat chicken and keep pet birds, according to bird medicine specialist Dr Bob Doneley. view more (2005-11-04)
HIV infection requires an accomplice: B cells with special protein direct HIV to T cells
HIV infection of T cells requires activation of a molecule on the surface of B cells, a finding that reveals yet another pathway the virus uses in its insidious attack on the immune system. view more (2006-08-14)
Researchers discover how compounds prevent viruses from entering cells
Compounds called defensins-known to prevent viruses from entering cells-appear to do so by preventing the virus from merging to cells' outer membrane. view more (2005-09-16)
Horse antibodies against the bird flu virus H5N1 are effective as treatment in mice
Antibodies against the bird flu virus H5N1, derived from horses, prevent mice infected with H5N1 from dying from the virus. view more (2006-03-28)
UK grid helps fight avian flu
During April, computers in the UK have been working overtime in the fight against avian flu. As part of an international collaboration, computers at eleven UK universities and research labs have put in one hundred thousand hours of time searching for possible drug components against the avian flu virus H5N1. view more (2006-05-04)
Cold sore virus might play role in Alzheimer's disease
A gene known to be a major risk factor for Alzheimer's disease puts out the welcome mat for the virus that causes cold sores, allowing the virus to be more active in the brain compared to other forms of the gene. view more (2007-01-04)
UCLA scientists discover immune response to HIV differs, even in identical twins
In findings illustrating the difficulty of developing an AIDS vaccine, UCLA AIDS Institute researchers report the immune systems in two HIV-positive identical twins responded to the infection in different ways. view more (2005-12-07)
The long research road to a new vaccine
The Food and Drug Administration (FDA) today announced the licensing of a new vaccine against a disease responsible for tens of thousands of hospitalizations in the United States and hundreds of thousands of deaths around the world each year. view more (2006-02-06)
St. Jude conducts first large-scale bird flu genome study
Unique resources at St. Jude Children's Research Hospital let researchers generate a "gold mine" of data to track evolution of bird flu virus genes and understand how they cooperate to cause disease. view more (2006-01-27)
Viral 'fitness' explains different resistance patterns to aids drugs
Some HIV medications lead to the development of drug-resistant HIV when patients take as few as two percent of their medications. view more (2006-01-11)
Study shows how herpes infects cornea, evades immune cells
Herpes virus has an unusual strategy for infecting cornea cells that may also explain how it evades the immune system, according to a study by researchers at the University of Illinois at Chicago College of Medicine. view more (2006-09-26)
Penn researchers determine structure of smallpox virus protein bound to DNA
Researchers at the University of Pennsylvania School of Medicine have determined the structure of an important smallpox virus enzyme and how it binds to DNA. view more (2006-08-07)
New drug candidate against HIV developed in Sweden
As a part of a research collaboration, scientists at the Sahlgrenska Academy at Göteborg University, Sweden, have developed a new drug candidate against HIV-infection. view more (2005-06-30)
Study details hepatitis C ability to block immune system response
Hepatitis C virus (HCV) is a worldwide public health problem. The World Health Organization estimates that 170 million people worldwide are chronically infected and that between 3-4 million are newly infected annually. view more (2006-05-19)
T cells activated to fight HIV basis for dendritic cell therapeutic vaccine
Having their immune system cells go through a laboratory version of boot camp may help patients win their battle against HIV. view more (2006-08-14)
Research uncovers signaling pathways related to brain-immune system links
New research on signaling pathways in immune cells bolsters evidence of connections between the central nervous system and the immune system. view more (2006-05-16)
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)
Molecular 'on/off switch' controls immune defenses against viruses
Much like flipping a light switch, the hepatitis C virus turns on human immune defenses upon entering the body but also turns off those defenses by manipulating interaction of key cellular proteins, UT Southwestern Medical Center researchers have found. view more (2006-12-26)
Landmark FSU study of hepatitis C virus solves mystery that has stymied quest for cure
The hepatitis C virus (HCV) infects more than 170 million people worldwide and leads to both acute and chronic liver diseases. view more (2006-02-08)
Epstein-Barr virus may be associated with multiple sclerosis
Young adults with high levels of antibodies against the Epstein-Barr virus, the virus that most often causes mononucleosis, may be more likely to develop multiple sclerosis 15 to 20 years later. view more (2006-04-11)
