Immune system response to viral DNA is unique
The human body has a unique immune system response to foreign DNA, suggesting that DNA viruses and RNA viruses are detected by different mechanisms. view more (2006-01-25)
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)
Scientists develop mathematical model to predict the immune response to influenza
Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). view more (2009-05-14)
A Different Antiviral For Treating SARS (p 2045)
A preliminary study published as a fast-track research letter in this week's issue of THE LANCET suggests that the antiviral agent glycyrrhizin could be more effective than other antivirals in the treatment of severe acute respiratory syndrome (SARS). Ribavirin is the most commonly used antiviral for treating SARS infection, used in combination... view more... (2003-06-11)
Study supports triple combination therapy for HIV
New evidence in this week’s BMJ supports the use of up to three antiviral drugs (triple therapy) to treat people with HIV. view more (2002-03-27)
Interferons For Treatment Of SARS? (p 293)
Authors of a research letter in this week's issue of THE LANCET suggest that recombinant interferons - synthetic versions of naturally occurring compounds of the immune system - could be a an effective treatment for Severe Acute Respiratory Syndrome (SARS). Although antivirals are probably essential for the treatment of SARS-CoV infection, the... view more... (2003-07-23)
Study reveals how a common virus eludes the immune system
Viruses have numerous tricks for dodging the immune system. In the September 7, 2009 issue of the Journal of Cell Biology, Stagg et al. reveal a key detail in one of these stratagems, identifying a protein that enables cyto¬megalovirus to shut down an antiviral defense (online August 31). view more (2009-08-31)
UQ research targets West Nile virus and dengue fever
Research conducted at The University of Queensland could contribute to the development of a vaccine and cure for West Nile virus and Dengue fever. view more (2008-12-11)
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)
Early treatment is key to combating hepatitis C virus
Canadian researchers have shown that patients who receive early treatment for Hepatitis C virus (HCV) within the first months following an infection, develop a rapid poly-functional immune response against HCV similar to when infection is erradicted spontaneously, according to a new study published in the Journal of Virology. view more (2008-08-11)
Second pathway behind HIV-associated immune system dysfunction identified
Researchers at the Partners AIDS Research Center at Massachusetts General Hospital (PARC-MGH) may have discovered a second molecular "switch" responsible for turning off the immune system's response against HIV. view more (2007-10-01)
Can the tonsils influence oral HIV transmission?
Current research demonstrates that the tonsils may possess the necessary factors to act as a transmission site for the spread of HIV. view more (2007-07-26)
Fighting drug-resistant flu viruses
Amid reports that swine flu viruses are developing the ability to shrug off existing antiviral drugs, scientists in Japan are reporting a first-of-its kind discovery that could foster a new genre of antivirals that sidestep resistance problems. view more (2009-07-15)
Immune responses spread from one protein to another in type 1 diabetes
Type 1 diabetes (T1D) is caused by the immune system inappropriately attacking the cells in the pancreas that produce insulin, the hormone that controls blood sugar levels. view more (2006-12-04)
New Therapeutic Vaccine for HIV/AIDS Eliminates Needles and Excessive Toxicity
DermaVir, a novel treatment for HIV/AIDS, offers a new option which complements and improves present drug therapies. The vaccine, applied topically to the skin, has demonstrated efficacy in boosting immune responses and controlling virus replication in chronically infected monkeys. This treatment possibly offers a new, non-invasive option for... view more... (2005-01-06)
Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. view more (2007-05-15)
IL-21 receptor plays an essential role in the Th2 immune response
During the immune response cells known as Th2 cells express a variety of cytokines (e.g. interleukin-4, -5, and -13), many of which stimulate B cells to proliferate and produce antibodies. view more (2006-06-16)
Early-stage immune system control of HIV may depend on inherited factors
How well an individual's immune system controls HIV during the earliest phases of infection appears to depend on both the specific versions of key immune-system molecules called HLA Class I that have been inherited, as well as on the fragments of viral protein those molecules display to the T lymphocytes that usually destroy infected cells. view more (2006-11-06)
Exhaustion of HIV-specific T cells may be caused by chronic exposure to virus
The "exhaustion" of immune cells that target HIV appears to result from chronic exposure to the virus, specifically exposure to the particular protein segments targeted by the pathogen-killing HIV-specific CD8 T cells. view more (2008-05-06)
New hope for HIV sufferers as immunosuppressant delays AIDS onset
A drug that suppresses the immune system delays the onset of AIDS in patients with HIV, according to a study published this week in BMC Medicine. Prednisolone, taken without any antiviral therapy, postponed the loss of T-cells that leads to AIDS in 50% of HIV sufferers by between 2 and 10 years. HIV leads to a complex disorder that combines an... view more... (2004-04-30)
