Study highlights HIV/AIDS challenge in American prison system
HIV/Aids is up to five times more prevalent in American prisons than in the general population. Adherence to treatment programs can be strictly monitored in prison.
Scientists join forces to explain HIV spread in Central and East Africa
Scientists studying biology and geography may seem worlds apart, but together they have answered a question that has defied explanation about the spread of the HIV-1 epidemic in Africa.
Certain cancers more common among HIV patients than non-HIV patients
Researchers at UT Southwestern Medical Center have found that non-AIDS-defining malignancies such as anal and lung cancer have become more prevalent among HIV-infected patients than non-HIV patients.
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.
Scientists determine dynamics of HIV transmission in UK heterosexuals
Among heterosexuals in the United Kingdom, HIV transmission can occur within networks of as many as 30 people, according to a new study by researchers.
New chemically activated antigen could expedite development of HIV vaccine
Scientists working to develop a vaccine for the human immunodeficiency virus report they have created the first antigen that induces protective antibodies capable of blocking infection of human cells by genetically-diverse strains of HIV.
HIV uses several strategies to escape immune pressure
A study of how HIV mutates in response to immune system pressure by Emory Vaccine Center researchers shows that the virus can take several escape routes, not one preferred route.
VOICE study, a major HIV prevention trial for women, is launched in Zimbabwe
Hopeful that some of the same antiretroviral drugs used to treat HIV infection can also prevent it, researchers from the Microbicide Trials Network have enrolled the first participants into a new, large-scale clinical trial testing two approaches of the strategy in women.
Clinical trial of antiretroviral-based HIV prevention strategies for women now under way
A new, large-scale clinical trial is examining whether antiretroviral medications normally used to treat HIV infection can also prevent HIV infection in women when applied as a vaginal gel or taken as oral tablets once daily.
How HIV cripples immune cells
The working group around Professor Dr. Oliver Fackler in the Virology Department of the Hygiene Institute of the Heidelberg University Hospital has discovered a mechanism in an animal model revealing how HIV, the AIDS pathogen, cripples immune cells: Cell mobility is inhibited by the HIV Nef protein.
