Gladstone investigators identify a new protective action for the powerful anti-HIV factor, APOBEC3G
Scientists at the Gladstone Institute of Virology and Immunology (GIVI) have identified a previously unknown function of APOBEC3G (A3G), a protein that acts against HIV, a finding that may lead to new approaches for controlling HIV infection. view more (2006-10-03)
NIAID scientists identify new cellular receptor for HIV
A cellular protein that helps guide immune cells to the gut has been newly identified as a target of HIV when the virus begins its assault on the body's immune system, according to researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). view more (2008-02-11)
Rapid HIV testing in the ER boosts diagnoses, screening
One in every 50 people screened for a suspected sexually transmitted infection (STI) in the Emergency Department at Henry Ford Hospital was found to be infected with HIV using a rapid blood sample screening test. view more (2008-10-27)
Scientists develop a new HIV microbicide -- and a way to mass produce it in plants
In what could be a major pharmaceutical breakthrough, research published online in The FASEB Journal describes how scientists from St George's, University of London have devised a one-two punch to stop HIV. view more (2009-05-29)
ABC-transporters expressed on endothelial cell membranes efflux anti-HIV drugs
Researchers at Tulane University Medical Center in New Orleans (USA) have discovered that drug-efflux pumps, belonging to the ATP-binding cassette (ABC) transporter family, are constitutively expressed on vascular endothelial cells. view more (2008-08-27)
New 'OPAL Therapy' presents simple, cost-effective method of treating HIV infection

HIV vaccine regimen demonstrates modest preventive effect in Thailand clinical study
In an encouraging development, an investigational vaccine regimen has been shown to be well-tolerated and to have a modest effect in preventing HIV infection in a clinical trial involving more than 16,000 adult participants in Thailand. view more (2009-09-24)
Tuberculosis presents major challenges to HIV treatment in developing countries
Human immunodeficiency virus (HIV) care and treatment programs in resource-limited settings must aggressively address tuberculosis (TB) and the emerging multidrug-resistant TB epidemic to save patient lives and to curb the global TB burden, a major cause of death for persons with HIV. view more (2008-07-23)
HIV Mortality in India Drops with Introduction of Generic Antiretroviral Therapy
The survival rate of HIV-infected patients in India has risen in response to a 20-fold drop in the price of antiretroviral therapy (ART), according to an article in the Nov. 15 issue of Clinical Infectious Diseases, now available online. view more (2005-10-20)
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)
Risk of HIV transmission highest early in infection
New evidence suggests that the risk of HIV transmission may be highest in the early stages of infection. According to a study published in the April 1 issue of The Journal of Infectious Diseases, now available online, early infection accounted for nearly half of all transmission occurrences in an HIV-infected population in the province of Quebec,... view more...

Adult circumcision reduces risk of HIV transmission without reducing sexual pleasure
Two studies presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA) show that adult circumcision reduces the risk of contracting the human immunodeficiency virus (HIV) and the risk of coital injury¬¬--without reducing pleasure or causing sexual dysfunction. view more (2009-04-27)
Researchers disprove long-standing belief about HIV treatment
Researchers at Wake Forest University Baptist Medical Center have disproved a long-standing clinical belief that the hepatitis C virus slows or stunts the immune system's ability to restore itself after HIV patients are treated with a combination of drugs known as the "cocktail." view more (2008-07-25)
Novel vaccine approach offers hope in fight against HIV
A research team may have broken the stubborn impasse that has frustrated the invention of an effective HIV vaccine, by using an approach that bypasses the usual path followed by vaccine developers. view more (2009-05-18)
HIV care providers applaud Congress' extension of Ryan White program
Medical providers on the front lines of HIV care applaud the U.S. Congress for extending the Ryan White HIV/AIDS Program, helping to ensure that more than half a million low-income, uninsured, or underinsured people living with HIV/AIDS have access to lifesaving care. view more (2009-10-22)

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)
HIV uses autophagy for its own means
Not satisfied with simply thwarting its host's defensive maneuvers, HIV actually twists one to its advantage, based on new findings from Kyei et al. in the July 27, 2009 issue of the Journal of Cell Biology (www.jcb.org). Vojo Deretic and colleagues suggest that autophagy-a stress response process-helps HIV to proliferate and that conversely,... view more... (2009-07-27)
Wild gorillas carriers of a SIV virus close to the AIDS virus
In 2005, 40.3 million people in the world, including 25.8 million in Sub-Saharan Africa, were living with HIV. The question of the origin of HIV-1, responsible for the AIDS pandemic, has been stimulating the scientific community for many years. view more (2006-11-14)
