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.

I am just back from Roatan, where I volunteered for a week at an HIV clinic run by Siempre Unidos. This is the "seldom seen" part of the island where the locals live and a good wage is $5.00/day. Honduras is the poorest of the Central American countries and has the highest prevalence of AIDS of any Spanish speaking country.

U.S. Military HIV Research Program (USMHRP) researcher Victoria R. Polonis, Ph.D., and colleagues released findings on a study of cross-clade neutralization patterns among HIV-1 strains from six major clades in the 5 Jun 2008 issue of Virology.

The links between HIV transmission and the degree to which people are able to adopt realistic plans to achieve future projects, in other words, hope, have been overlooked in policies to tackle HIV/AIDS. New research funded by the Economic and Social Research Council (ESRC) argues that hope is a powerful tool in the battle to stop the spread of HIV/AIDS.

Approximately half of all new HIV infections in the United States result from the sexual risk behaviors of men who have sex with men. Now, a new study led by a researcher at The Miriam Hospital provides additional insight into which of these men are most likely to transmit HIV to others, potentially paving the way for the development of more targeted prevention programs.

Hopes languished last September when a promising candidate HIV vaccine failed to work. Despite this setback, many researchers still believe immunization is possible, and a new study suggests they're correct—at least at the cellular level.

Researchers have shown that they can effectively tackle HIV-1 with small bits of gene-silencing RNA by delivering them directly to infected T cells, the major targets of the virus.

Johns Hopkins expert in HIV and how the AIDS virus hides in the body says antiretroviral drugs have stopped HIV from replicating, the first of three key steps needed to rid people of the virus.

Black girls who undergo gender and culturally tailored HIV interventions are significantly less likely to contract a sexually transmitted disease.

In a double-blind, placebo-controlled clinical trial to assess the impact of smoked medical cannabis, or marijuana, on the neuropathic pain associated with HIV, researchers at the University of California, San Diego School of Medicine found that reported pain relief was greater with cannabis than with a placebo.

University of Minnesota researchers have answered a key question as to why antiretroviral therapy isn't effective in restoring immunity in HIV-infected patients.

Argos Therapeutics and Université de Montréal today announced the presentation of new information on Argos'process for developing dendritic cell-based immunotherapies for HIV.
