Evolutionary battle scars' identify enhanced antiviral activity
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms. view more (2008-01-25)
Case Western Reserve researchers discover the key to malaria susceptibility in children
A team of researchers from Case Western Reserve University School of Medicine have solved the mystery of why some children are more susceptible to malaria infection and anemia. view more (2009-07-28)
Oxford Biomedica Obtains Further Fundamental Patent For Lentiviral Gene Therapy Technology
Oxford BioMedica plc announced today that it has received allowance from the US Patent Office for a further patent covering its proprietary LentiVector technology. This additional patent compliments the US patent 6,312,682 issued in November 2001 and both include broad composition of matter claims and methods of production claims for lentiviral... view more...

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)

Scientists are using designs in nature from extreme environments to overcome the challenges of producing materials on the nanometre scale. view more (2008-10-15)
Selenium may slow march of AIDS
Increasing the production of naturally occurring proteins that contain selenium in human blood cells slows down multiplication of the AIDS virus, according to biochemists. view more (2008-12-01)
International Surveillance System Suggests 2002 Gastroenteritis Outbreaks Arose From New Variant Norovirus (Pp 671, 682)
The increase in severe outbreaks of gastroenteritis in 2002-including the notorious outbreaks on US cruise ships-were probably a result of a new variant of norovirus, conclude authors of a study in this week's issue of THE LANCET. Ben Lopman from the UK Health Protection Agency and European colleagues analysed data collected through a... view more... (2004-02-25)
Cancer-killing viruses influence tumor blood-vessel growth
Viruses genetically designed to kill cancer cells offer a promising strategy for treating incurable brain tumors such as glioblastoma, but the body's natural defenses often eliminate the viruses before they can eliminate the tumor. view more (2008-06-11)
TB breakthrough could lead to stronger vaccine
A breakthrough strategy to improve the effectiveness of the only tuberculosis vaccine approved for humans provided superior protection against the deadly disease in a pre-clinical test, report scientists at The University of Texas Health Science Center at Houston in Nature Medicine's Advance Online Publication March 1. view more (2009-03-04)
Computer simulation captures immune response to flu
Researchers have successfully tested first the first time a computer simulation of major portions of the body's immune reaction to influenza type A, with implications for treatment design and preparation ahead of future pandemics, according to work accepted for publication, and posted online, by the Journal of Virology. view more (2009-05-19)
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)
New treatment model for HIV
Treatment of HIV patients must balance the need to suppress viral replication against the harmful side effects and significant cost to the patient of antiretroviral therapy. view more (2007-07-13)
LIAI scientists make major advance in the fight against chronic virus infections
A major finding that could lead to a new approach for treating hepatitis C and other chronic virus infections was announced today by researchers at the La Jolla Institute for Allergy & Immunology (LIAI). view more (2006-10-10)
Cedars-Sinai researchers discover treatment for deadly brain tumors and infections
In a study published in the March 15 issue of The Journal of Immunology, researchers at Board of Governors' Gene Therapeutics Research Institute at Cedars-Sinai Medical Center have developed a way to overcome immune privilege in the brain to eradicate potentially deadly brain tumors such as glioblastoma multiforme and other types of brain... view more...

NIH scientists discover crucial control in long-lasting immunity
National Institutes of Health (NIH) scientists have identified a protein that plays matchmaker between two key types of white blood cells, T and B cells, enabling them to interact in a way that is crucial to establishing long-lasting immunity after an infection. view more (2008-10-13)
Shorter colds, milder flu may follow from newly revealed immune mechanism
Enlisted to help fight viral infections, immune cells called macrophages consume virus-infected cells to stop the spread of the disease in the body. view more (2005-10-10)
Cell death suppression increases efficacy of M2 vaccines
Significant public attention has recently been focused on the development of new anti-influenza (flu) vaccines that provide protection against a broad spectrum of viral strains. One proposed strategy is to utilize conserved viral protein, M2. Clinical trials of M2-containing influenza vaccines were recently initiated by US and European companies. view more (2008-01-16)
UK STUDY SHOWS DOUBLING OF WHEEZING AMONG PRESCHOOL CHILDREN IN 1990s (p 1821)
A study in this week's issue of THE LANCET describes an increase of all types of wheezing disorders in preschool children over the past 10 years A substantial increase in reported wheeze and doctor-diagnosed asthma in schoolchildren has been documented since the 1960s in several countries. However, there is no consistent evidence for a change in... view more... (2001-06-06)
Scripps scientists create first crystal structure of an intermediate particle in virus assembly
The structure, described February 8 in an advance online publication of the journal Nature, provides fresh insights into the elegant dance that viral proteins perform to create the infectious structure that causes all manner of misery and disease, say researchers. view more (2009-02-09)
MU Researcher Refining Synthetic Molecules to Prevent HIV Resistance
Evolving HIV viral strains and the adverse side effects associated with long-term exposure to current treatments propel scientists to continue exploring alternative HIV treatments. view more (2008-12-17)
