MV-GFP extends survival of animals with medulloblastoma

A strain of measles virus engineered to kill cancer cells prolongs survival in a model of medulloblastoma that is disseminated in the fluid around the brain, according to a new study by researchers at Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute and the Mayo Clinic.

Reuters examines upcoming WHO meeting to discuss debate over bird flu research

Bird flu experts are scheduled to begin a two-day meeting at the WHO in Geneva on Thursday "to try to settle an unprecedented row over a call to censor publication of two scientific studies which detail how to mutate H5N1 bird flu viruses into a form that could cause a deadly human pandemic," Reuters reports in an article describing the debate in detail.

Bird flu controversy an opportunity to set a higher tone for public debate

In this Huffington Post opinion piece, Leslie Gerwin, associate director of law and public affairs at Princeton University, reflects on the recent controversy over whether to research and publish data about potentially dangerous strains of the H5N1 bird flu virus, writing, "I am disturbed that so much coverage of this dispute -- so deserving of sober consideration -- is fixated on fear mongering."

Tissues in SIV-infected monkeys can ramp up production of Tregs

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.

Promising compound may counteract HIV's ability to hijack CD59 protein

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.

Fair trade agreement between E.U., India could impede access to medicine for world's poor

"Current negotiations on a free trade agreement (FTA) between the European Union and India are causing serious concern in many quarters over future access to cheap generic medicines used to treat some of the world's great public health threats: HIV, tuberculosis and malaria, and also cancer," Philippe Douste-Blazy, U.N. special adviser on innovative financing for development and chair of UNITAID, and Denis Broun, executive director of UNITAID, write in this post in the Guardian's "Poverty Matters Blog."

Scientists test new 'therapeutic vaccine' against HIV on volunteers

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.

Starving HIV virus could be the basis for future therapy: Study

In a medical breakthrough researchers at NYU Langone Medical Center and colleagues have shown how some cells in the body can repel attacks from HIV by starving the virus of the building blocks of life.

Tenofovir associated with significant risk of kidney damage and chronic kidney disease

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 and the University of California, San Francisco (UCSF).

DARPA awards fourth milestone payment of $3.56M to Medicago

Medicago USA Inc., a wholly owned subsidiary of Medicago Inc., a biotechnology company focused on developing highly effective and competitive vaccines based on proprietary manufacturing technologies and Virus-Like Particles (VLPs), today announced it has received the fourth milestone payment of US$3.56 million from the Defense Advanced Research Projects Agency.

SAMHD1 protein cuts off raw material that HIV needs to create DNA and replicate

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate, according to research published online in Nature Immunology.

Study reveals how SAMHD1 works to protect dendritic cells from HIV virus

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.

Scientists discover ferocity of immune system after viral infection

A scientific team led by researchers at the University of Geneva (UNIGE) and the Charité Berlin Medical University has made a completely unprecedented discovery showing how much our immune system is provoked into action when confronted by viral intruders.

Gene therapy to promote remyelination in mouse model of MS

Our bodies are full of tiny superheroes-antibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelin-a material that forms a protective, insulating cape around the axons of our nerve cells so that they can send signals quickly and efficiently. But myelin, and the specialized cells called oligodendrocytes that make it, become damaged in demyelinating diseases like multiple sclerosis (MS), leaving neurons without their myelin sheaths.

NewsOne examines HIV in Caribbean

NewsOne examines HIV in the Caribbean, where one percent of the population is infected with the virus, "small in comparison to numbers found in the global scheme but significant enough to distinguish it as the second-highest region with HIV/AIDS outside of sub-Saharan Africa."
