How HIV vaccine might have increased odds of infection
In September 2007, a phase II HIV-1 vaccine trial was abruptly halted when researchers found that the vaccine may have promoted, rather than prevented, HIV infection.   view more (2008-11-03)

Antiretroviral Therapy Effective In Reducing Mother-to-child HIV-1 Transmission When Started After Childbirth (p 1171)
Results of a study from Malawi in this week's issue of THE LANCET highlight how antiretroviral therapy targeted at babies soon after childbirth (because their mothers' HIV diagnosis was made around the time of delivery) is still effective in preventing vertical HIV-1 transmission from mothers to their children. Zidovudine and nevirapine have been... view more... (2003-10-08)

A new step towards an AIDS vaccine
Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body.   view more (2005-10-14)

Well-armed immune cells help long-term nonprogressors contain HIV
To help develop an effective HIV vaccine, researchers are trying to better understand how the immune systems of a small minority of HIV-infected people known as long-term non-progressors (LTNPs) contain the virus naturally.   view more (2008-12-05)

A low prevalence of H pylori in HIV-positive patients
Helicobacter pylori has been extensively studied and proven to be the main cause of chronic gastritis and peptic ulcer in the HIV-negative population.   view more (2007-10-17)

Why are so few HIV/AIDS trials conducted in Africa?
People in sub-Saharan Africa carry the heaviest burden of HIV and AIDS, yet very few trials have been conducted on the African continent over the past two decades, say researchers in this week's BMJ.   view more (2005-09-30)

MicroRNAs help control HIV life cycle
Scientists at Burnham Institute for Medical Research (Burnham) have discovered that specific microRNAs (non-coding RNAs that interfere with gene expression) reduce HIV replication and infectivity in human T-cells.   view more (2009-06-26)

Immune exhaustion in HIV infection
As HIV disease progresses in a person infected with the HIV virus, a group of cells in the immune system, the CD8+ T lymphocytes, become "exhausted," losing many of their abilities to kill other cells infected by the virus.   view more (2008-05-06)

Eastern Europe Facing Major Aids Epidemic (p 1035)
Authors of a review in this week's issue of THE LANCET predict that social problems in former eastern-block countries resulting in large numbers of injecting-drug users and a rise in sexually transmitted diseases will soon cause a major HIV/AIDS epidemic in eastern Europe. Fran'§oise Hamers and Angela Downs describe recent trends in the HIV... view more... (2003-03-20)

State laws may limit implementation of CDC's recommendations for routine HIV testing
A new study concludes that routine testing for HIV recommended by the Centers for Disease Control (CDC) may violate many state laws.   view more (2007-10-10)

If started early, HIV treatment reduces death rates toward background levels in African countries
Mortality rates of people starting HIV treatment in four African countries approach those of the general population over time, provided that treatment is started before the immune system has been severely damaged, according to research published this week in the open-access journal PLoS Medicine.    view more (2009-04-28)

Are HIV Infection And Personality Linked?
Currently, HIV is one of the most widely spread epidemics in the world. The specificity of the mode of transmission, the well-known severity of the prognosis, and the kind of therapies used are peculiarities of this illness. Personality traits of individuals with HIV may influence conditions for the infection itself. On the other hand, it is... view more... (2004-11-18)

AFRICAN HIV-1 EPIDEMIC NOT CAUSED BY MORE INFECTIOUS VIRAL SUBTYPE (p 1149)
The explosive HIV-1 epidemic in sub-Saharan Africa is unlikely to be the result of a viral subtype with increased infectivity, according to the results of a study published in this week’s issue of THE LANCET. The HIV-1 epidemic in eastern and southern sub-Saharan Africa is mainly caused by HIV-1 subtypes A, C, and D, whereas those in the USA... view more... (2001-04-11)

How breastfeeding affects HIV transmission
Mother to child transmission of HIV accounts for a large proportion of HIV infections in children, with many infected as a result of breastfeeding, which requires transfer of the virus across mucosal barriers.   view more (2005-10-21)

Asthma risk increases in children treated for HIV
Children whose immune systems rebound after treatment with potent anti-viral drugs for HIV infection face an increased risk of developing asthma, said a federally funded consortium of researchers led by those from Baylor College of Medicine in a report that appears online in the Journal of Allergy and Clinical Immunology.    view more (2008-07-02)

Researchers induce HIV-neutralizing antibodies that recognize HIV-1 envelope protein, lipids
For the first time, researchers have experimentally induced antibodies that neutralize HIV-1 and simultaneously recognize both HIV-1 envelope protein and lipids.   view more (2009-09-02)

FURTHER STEPS TOWARDS A VACCINE AGAINST HIV
For white blood cells in the human body to be infected by the HIV virus, proteins in the virus must be allowed to interact with a number of different components on the surface of the white blood cell. Ideally anti-HIV preventive therapy or vaccines would prevent several of these interactions taking place and would, therefore, reduce the likelihood... view more... (1999-03-11)

Harvard scientists solve mystery about why HIV patients are more susceptible to TB infection
A team of Harvard scientists has taken an important first step toward the development of new treatments to help people with HIV battle Mycobacterium tuberculosis (TB) infection.   view more (2009-07-01)

Herpes drug inhibits HIV in patients infected with both viruses
Researchers at the U.S. National Institutes of Health (NIH), McGill University and other institutions have discovered how a simple antiviral drug developed decades ago suppresses HIV in patients who are also infected with herpes.   view more (2008-09-16)

Sperm may play leading role in spreading HIV
Sperm, and not just the fluid it bathes in, can transmit HIV to macrophages, T cells, and dendritic cells (DCs), report a team led by Ana Ceballos at the University of Buenos Aires in Argentina.   view more (2009-10-26)
