Effective HIV control may depend on viral protein targeted by immune cells
An effective response of the immune system's 'killer' T cells against infection with HIV may depend on exactly which viral protein is targeted, according to an international group of researchers. view more (2006-12-18)
Quality not quantity important for immune response to HIV
When it comes to an immune response against HIV, research funded by the Wellcome Trust in the UK and the National Institutes of Health in the US has found that bigger is not necessarily better, contrary to conventional medical wisdom. view more (2006-12-18)
Criminalizing HIV transmission is a threat to public health, say experts
Experts in this week's BMJ express serious concerns about the public health impact of criminalising HIV transmission. view more (2006-09-29)
Malaria treatment efficacy compromised in certain HIV-positive patients
A weakened immune response resulting from HIV infection can lead to trouble when it comes to treating malaria. view more (2006-09-08)
Hopkins study suggests commercially available antibiotic may help fight dementia in HIV patients
An antibiotic commonly used to treat a variety of serious infections may also help prevent dementia in HIV patients, according to a test-tube study of human brain cells by Johns Hopkins University School of Medicine neurologist Jeffrey Rumbaugh, M.D., Ph.D. view more (2006-04-06)
Ethnic differences in response to HIV medicines
Researchers from the University of Massachusetts and the University of Pennsylvania have shown that race/ethnicity is a predictor of plasma lipids in patients with HIV-1 on HAART (highly active antiretroviral therapy). view more (2006-01-24)
Autoimmune overload may damage HIV-infected brain
Researchers studying the evolution of the human immunodeficiency virus (HIV) in the brain have found that the body's own defenses may cause HIV-related dementia. view more (2005-09-30)
AIDS vaccine research offers new insights on survival
New insights into how a subpopulation of helper T-cells provides immunity and promotes survival following infection with an AIDS-like virus offer a new means of predicting an AIDS vaccine's effectiveness, a discovery that could help scientists as they test these vaccines in clinical trials. view more (2006-06-12)
International HIV/AIDS trial finds continuous antiretroviral therapy superior to episodic therapy
The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), today announced that enrollment into a large international HIV/AIDS trial comparing continuous antiretroviral therapy with episodic drug treatment guided by levels of CD4+ cells has been stopped. view more (2006-01-18)
Drug to Block Mother-to-Child HIV Transmission Induces Resistance
The incidence of drug resistance associated with single-dose nevirapine, a drug used to prevent mother-to-child transmission of HIV-1, may be substantially higher than previously thought and of particular risk for those infected with HIV-1 subtype C, according to three new studies published in the July 1 issue of The Journal of Infectious... view more...

Government is treating the symptoms and not fighting the causes of infectious diseases, say scientists
The Microbiology Awareness Campaign gathered momentum yesterday at the House of Lords when scientists informed Peers and MPs that new and re-emerging infectious diseases could spell trouble if not tackled soon. The experts said that without targeted government funding for microbiological research, serious health and economic problems may lie ahead... view more... (2005-03-02)
HIV exploits competition among T-cells
A new HIV study shows how competition among the human immune system's T cells allows the virus to escape destruction and eventually develop into full-blown AIDS. view more (2006-10-17)
HIV is a 'double hit' to the brain
New evidence reported in the August issue of Cell Stem Cell, a publication of Cell Press, offers a novel perspective on how the HIV/AIDS virus leads to learning and memory deficits, a condition known as HIV-associated dementia. view more (2007-08-16)
Researchers disprove 'fat redistribution syndrome' among men taking HIV drugs
There is no syndrome that causes increased belly fat and decreased facial and limb fat among HIV-positive men who take antiretroviral drugs. view more (2005-10-14)
Heavy drinking can hasten the progression of the simian immunodeficiency virus disease
Alcohol abuse can impair a person's immune system, leading to infections like pneumonia. Alcohol abuse is also more common among individuals already infected with human immunodeficiency virus (HIV) than among the population as a whole. view more (2006-09-25)
Why were the HIV prevention trials in commercial sex workers abandoned?
One promising approach to help stem the global HIV epidemic is to give commercial sex workers an HIV medication (such as the drug tenofovir) before they have high risk sex in the hope of reducing their chances of becoming infected, an approach called "pre-exposure prophylaxis" (PREP). view more (2005-07-19)
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)
Anti-HIV drugs unlikely to stop HIV spread
Researchers believe antiretroviral therapy (ART) will not be effective in stopping HIV epidemics even if it is made universally available in poorer countries, and that widespread use could even lead to an increase in the numbers infected with HIV. view more (2006-03-14)
Researchers reveal key human protein's structure, promising new discoveries for leukemia, AIDS and cellular calcium release
Cornell University researchers have discovered the 3-D crystal structure of a protein, human CD38, which may lead to important discoveries about how cells release calcium - a mineral used in almost every cellular process. view more (2005-09-20)
Amanda Fisher receives EMBO Gold Medal
Amanda Fisher, group head at the MRC Clinical Science Centre, London (U.K.), is this year`s winner of the EMBO Gold Medal. This prestigious prize is awarded by EMBO in recognition of Amanda Fisher`s outstanding work on nuclear organization and gene expression as well as for her research on the molecular characterisation of the AIDS virus (HIV).... view more...
