HIV infection requires an accomplice: B cells with special protein direct HIV to T cells
HIV infection of T cells requires activation of a molecule on the surface of B cells, a finding that reveals yet another pathway the virus uses in its insidious attack on the immune system.   view more (2006-08-14)

Viral 'fitness' explains different resistance patterns to aids drugs
Some HIV medications lead to the development of drug-resistant HIV when patients take as few as two percent of their medications.   view more (2006-01-11)

Montreal researchers identify defects of immune cells
Researchers at Université de Montréal and the Institut de recherches cliniques de Montréal (IRCM) have successfully identified a defective immune cell population that determines susceptibility to candidiasis, a common and often debilitating infection in individuals infected... view more (2006-06-22)

Landmark FSU study of hepatitis C virus solves mystery that has stymied quest for cure
The hepatitis C virus (HCV) infects more than 170 million people worldwide and leads to both acute and chronic liver diseases.   view more (2006-02-08)

Teenagers know about condoms ... so why don't they use them?
The review of qualitative studies, published today in The Lancet, looked at 268 studies of the sexual behaviour of under-25-year-olds from South Africa to Sweden. It reveals how, in all countries, social expectations of how men and women should behave frustrate campaigners' efforts to encourage... view more (2006-11-03)

HIV inserts into human genome using a DNA-associated protein
A human DNA-associated protein called LEDGF is the first such molecule found to control the location of HIV integration in human cells.   view more (2005-11-28)

New drug candidate against HIV developed in Sweden
As a part of a research collaboration, scientists at the Sahlgrenska Academy at G√∂teborg University, Sweden, have developed a new drug candidate against HIV-infection.   view more (2005-06-30)

Yale biologists 'trick' viruses into extinction
While human changes to the environment cause conservation biologists to worry about species extinction, Yale biologists are reversing the logic by trying to trap viruses in habitats that force their extinction, according to a report in Ecology Letters.   view more (2007-02-13)

T cells activated to fight HIV basis for dendritic cell therapeutic vaccine
Having their immune system cells go through a laboratory version of boot camp may help patients win their battle against HIV.   view more (2006-08-14)

Research uncovers signaling pathways related to brain-immune system links
New research on signaling pathways in immune cells bolsters evidence of connections between the central nervous system and the immune system.   view more (2006-05-16)

Immunologists find better way to boost the immune system
Immunologists have discovered how to manipulate the immune system to increase its power and protect the body from successive viral infections.   view more (2008-01-23)

Meth Promotes Spread of Virus in HIV-Infected Users
Researchers at the University at Buffalo have presented the first evidence that the addictive drug methamphetamine, or meth, also commonly known as "speed" or "crystal," increases production of a docking protein that promotes the spread of the HIV-1 virus in infected users.   view more (2006-08-07)

First large-scale HIV vaccine trial in South Africa opens
A large-scale clinical trial of a candidate HIV vaccine—which previously showed promise in smaller studies in the United States and elsewhere—has now opened in South Africa.   view more (2007-02-09)

'POZ parties' signal potential to spread HIV 'superinfection'
The emergence of "POZ Parties"-parties exclusively for HIV positive men to meet other HIV positive men for sex-signals the potential to spread HIV "superinfection,"suggests research in Sexually Transmitted Infections.   view more (2005-09-29)

Laser Blasts Viruses in Blood
A father-son research team working from separate laboratory benches across the country has discovered a new use for lasers - zapping viruses out of blood. The technique, which holds promise for disinfecting blood for transfusions, uses a low-power laser beam with a pulse lasting just fractions of... view more (2007-09-05)

Defense peptide found in primates may block some human HIV transmissions
As primates evolved 7 million years ago, the more advanced species stopped making a protein that University of Central Florida researchers believe can effectively block the HIV-1 virus from entering and infecting blood cells.   view more (2006-08-10)

Scientists find potential 'off-switch' for HIV virus
While there is no cure for lingering viral infections such as HIV and herpes, a recent study at Princeton University suggests it may be possible to deactivate such viruses indefinitely with the flick of a genetic switch.   view more (2007-01-12)

Effects of bacterial pneumonia no worse for HIV-positive patients
Pneumonia doesn't appear to harm HIV-positive patients any more than those without HIV, according to a new international study conducted in part by the University of Alberta.   view more (2005-09-28)

Landmark discovery of a Kaposi's sarcoma-associated herpesvirus receptor
Researchers at the National Institute of Allergy and Infectious Disease (NIAID), a component of the National Institutes of Health (NIH), have identified a critical human cell surface molecule involved in infection by Kaposi's sarcoma herpesvirus (KSHV), the virus that causes Kaposi's sarcoma and... view more (2006-04-07)

HIV accessory protein disables host immunity via receptor-protein intermediary
Researchers at the University of Pennsylvania School of Medicine discovered that an HIV-1 accessory protein called Vpr destroys the host cell's ability to survive by binding to a host receptor.   view more (2006-03-31)

HIV vaccine takes different tack to boosting immune response
esearchers at Baylor College of Medicine (BCM) in Houston have reason to believe their unorthodox vaccine could one day help to prevent or control HIV infection.   view more (2006-01-03)

Science commentary stresses need for collaboration at local level in HIV-prevention studies
Clinical trials of drugs intended to prevent HIV infection in high-risk populations must be developed and carried out in close collaboration with the local communities and national governments of the countries in which they are conducted, according to 18 international leaders in HIV prevention... view more (2005-10-03)

UCLA researchers develop T-cells from human embryonic stem cells
Researchers from the UCLA AIDS Institute and the Institute for Stem Cell Biology and Medicine have demonstrated for the first time that human embryonic stem cells can be genetically manipulated and coaxed to develop into mature T-cells, raising hopes for a gene therapy to combat AIDS.   view more (2006-07-05)

UCLA scientists discover immune response to HIV differs, even in identical twins
In findings illustrating the difficulty of developing an AIDS vaccine, UCLA AIDS Institute researchers report the immune systems in two HIV-positive identical twins responded to the infection in different ways.   view more (2005-12-07)

HIV-1 kills immune cells in the gut that may never bounce back
People with HIV have been living longer, healthier lives since the development of highly active antiretroviral therapy (or HAART) in 1995. In fact, most patients on the drug regimen do so well that, according to blood tests, their immune cells appear to return to pre-HIV levels.   view more (2006-12-05)
