SIV Infection May Lead To Increase In Immune-Suppressive Treg Cells
Tissue in monkeys infected with a close relative of HIV can ramp up production of a type of T cell that actually weakens the body's attack against the invading virus. The discovery, in lymph nodes draining the intestinal tract, could help explain how the HIV virus evades the body's immune defenses...

The Cost-Effectiveness Of HAART Underestimated
Bohdan Nosyk and Julio Montaner of the British Columbia Centre for Excellence in HIV/AIDS in Vancouver, Canada argue in an Essay published in this week's PLoS Medicine that the cost-effectiveness of HAART roll out has been significantly underestimated, because economic analyses have not yet taken into account the beneficial impact of HAART on prevention of HIV transmission...

HIV Resistance Among Many Sex Workers In Africa
According to a new study, HIV-resistant sex workers in Africa have a weak inflammatory response in their vaginas. The researchers, led by Dr. Michel Roger of the University of Montreal Hospital Centre and the university's Department of Microbiology and Immunology, were surprised by this finding, as they expected the opposite, due to the women's high exposure to the virus...

Scientist Works To Detach Protein That HIV Uses As Protective Shield
One of the frustrations for scientists working on HIV/AIDS treatments has been the human immunodeficiency virus' ability to evade the body's immune system. Now an Indiana University researcher has discovered a compound that could help put the immune system back in the hunt. It's not that the human immune system doesn't recognize HIV...

Human Testing Of New HIV-Vaccine
Scientists from the Antwerp Institute of Tropical Medicine, Antwerp University Hospital and Antwerp University have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were 'so to say' vaccinated with their own cells. The researchers filtered certain white blood cells out of the volunteer's blood, 'loaded' them outside the body and then gave them back...

Kidney Damage Risk Linked To Tenofovir, Leading HIV Medication
Tenofovir, one of the most effective and commonly prescribed antiretroviral medications for HIV/AIDS, is associated with a significant risk of kidney damage and chronic kidney disease that increases over time, according to a study of more than 10,000 patients led by researchers at the San Francisco VA Medical Center (SFVAMC) and the University of California, San Francisco (UCSF)...

How Protein Protects Cells From HIV Infection
A novel discovery by researchers at NYU Langone Medical Center and colleagues reveals a mechanism by which the immune system tries to halt the spread of HIV. Harnessing this mechanism may open up new paths for therapeutic research aimed at slowing the virus' progression to AIDS. The study appears online ahead of print today in Nature Immunology...

Protein Starves HIV, Thus Protecting Cells
A protein called SAMHD1 has been found to starve HIV in cells so that it cannot do anything, thus making the cell resistant to HIV infection, researchers at NYU Langone Medical Center reported in Nature Immunology. The authors explained that their discovery could pave the way for new therapeutic research at halting or slowing the HIV's progression to AIDS. Research co-leader, Nathaniel R...

In HIV Prevention More Focus Needed On Men
Edward Mills of the University of Ottawa, Canada and colleagues argue in this week's PLoS Medicine that the HIV/AIDS response in Africa needs a more balanced approach to gender, so that both men and women are involved in HIV treatment and prevention...

When HIV Patients Waver On Meds
According to a new analysis of hundreds of recorded office visits, doctors and nurse practitioners typically issued orders and asked closed or leading questions when talking to their HIV-positive patients about adherence to antiretroviral therapy. Attempts at problem-solving with patients who had lapsed occurred in less than a quarter of visits. Take your medicine, Doctor's orders...

Tracking The Birth Of An Evolutionary Arms Race Between HIV-Like Viruses And Primate Genomes
Using a combination of evolutionary biology and virology, scientists at Fred Hutchinson Cancer Research Center have traced the birth of the ability of some HIV-related viruses to defeat a newly discovered cellular-defense system in primates. The research, led by Michael Emerman, Ph.D., a member of the Hutchinson Center's Human Biology and Basic Sciences Division, and Harmit Malik, Ph.D...

Antiretrovirals Raise Birth Defect Risk
HIV-positive mothers can protected their babies from becoming infected with the virus if they take antiretroviral drugs during pregnancy. However, even though these drugs prevent transmitting the disease to the child, they could potentially cause birth defects like cleft lip and palate...

In HIV-Positive Patients, Standard Treatments For Head And Neck Cancer Are Less Effective
Radiation therapy with or without chemotherapy is less effective for patients with HIV when compared to the recurrence and overall survival rates in patients who do not have HIV, according to a study presented at the Multidisciplinary Head and Neck Cancer Symposium, sponsored by AHNS, ASCO, ASTRO and SNM. Treating head and neck cancer in HIV-positive patients is a challenge for oncologists...
