The US is one of only about a dozen countries which bars entry for those with positive HIV status. U.S. President Barack Obama said on Friday that the U.S. would lift the ban in 2010, confirming the move as he signed the Ryan White HIV/Aids Treatment Extension Act into law.

Discovery by Hebrew University of Jerusalem researchers of an additional role for a key molecule in our bodies provides a further step in world-wide efforts to develop genetic regulation aimed at controlling many diseases, including AIDS and various types of cancers.

In order to be able to ward off disease pathogens, immune cells must be mobile and be able to establish contact with each other. 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.

HIV / AIDS is a big worry in the adult film industry, as one might expect. Thursday, two former adult film actresses, Jan Meza (left in picture) and Shelley Lubben, spoke at a press conference Thursday in Los Angeles with the AIDS Healthcare Foundation (AHF), an AIDS advocacy group, and The Pink Cross, a group that helps people exit the adult film industry, calling for condom use in all adult films.

Although the AIDS virus (HIV-1) entered the human population through chimpanzees, scientists have long believed that chimpanzees don't develop AIDS. But a new study from an international team, including University of Minnesota professors Anne Pusey and Michael Wilson, shows that chimpanzees infected with SIV (simian immunodeficiency virus), the precursor to HIV-1, do contract and die from AIDS. The discovery is published in the July 23 issue of Nature.

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.

One of the continuing mysteries of the HIV/AIDS epidemic is why women usually develop lower viral levels than men following acute HIV-1 infection but progress faster to AIDS than men with similar viral loads.

Those in the United States living with HIV/AIDS are more likely to use marijuana than those in Kenya, South Africa or Puerto Rica to alleviate their symptoms, according to a new study published in Clinical Nursing Research, published by SAGE.

Rutgers AIDS researchers Gail Ferstandig Arnold and Eddy Arnold may have turned a corner in their search for a HIV vaccine. In a paper just published in the Journal of Virology, the husband and wife duo and their colleagues report on their research progress.

In a collaborative study with the World Health Organization and seven other laboratories, researchers at the Stanford University School of Medicine have compiled a list of 93 common mutations of the AIDS virus associated with drug resistance that will be used to track future resistance trends throughout the world.

Scientists have developed an AIDS treatment gel that shows promise in the prevention of infection from the AIDS virus. An experimental vaginal gel is the first study that offers any hope of a microbicide becoming a part of the medical weaponry to battle HIV, scientists said on Monday.

Why do some HIV patients manage to control the progression of their infection naturally over long periods of time? As part of a nation-wide investigation, a team of researchers will examine that question and others as they work to develop new strategies to fight AIDS.
