New research from UCSF examining HIV among men who have sex with men (MSM) in the township of Soweto in South Africa has found that a third of gay-identified men are infected with HIV.

Brazil's nearly two-decade effort to treat people living with HIV and AIDS shows that developing countries can successfully combat the epidemic. Inexpensive generic medicines are a large part of the solution, say researchers from Brown University and the Harvard School of Public Health.

Scientists at Albert Einstein College of Medicine of Yeshiva University have devised a laboratory test for predicting whether microbicides against HIV are safe for human use. The researchers have also discovered why several supposedly "safe" microbicides made women more susceptible to HIV infection. The study appears today in the online version of the Journal of Infectious Diseases.

Researchers from the newly-established VGTI Florida and the University of Montreal have uncovered a possible method for eradicating HIV infection in the human body. The researchers have also revealed new information which demonstrates how HIV persists in the body - even in patients receiving drug treatments - and how the virus continues to replicate itself in individuals undergoing treatment.

An investigational vaginal gel intended to prevent HIV infection in women has demonstrated encouraging signs of success in a clinical trial conducted in Africa and the United States.

Researchers have discovered a potentially important new resistance factor in the battle against HIV: blood types. An international team of researchers from Canadian Blood Services, The Hospital for Sick Children (SickKids) and Lund University in Sweden have discovered that certain blood types are more predisposed to contracting HIV, while others are more effective at fending it off.

Babies born to HIV-positive mothers and given the antiretroviral drug nevirapine through the first six weeks of life to prevent infection via breast-feeding are at high risk for developing drug-resistant HIV if they get infected anyway, a team of researchers report.

Education has found its way onto the soccer fields of North Carolina – in the form of a social experiment that may have all the right ingredients to change the direction of Latino health in the United States.

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. A new study by a team of researchers at the Montpellier Institute of Molecular Genetics in France shows how the vaccine could have enhanced HIV infection.

A new study looking at unprotected intercourse within gay couples when each partner has established HIV-infection found a correlation between anti-HIV immune response and sexual activity.

The Salk Institute for Biological Studies and Burnham Institute for Medical Research today announced 295 host cell factors that are involved in human immunodeficiency virus (HIV) infection.

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. Their study was published in the Sept. 11 issue of the journal Cell Host and Microbe.
