Changes in HIV genetic code determine severity of disease

In a finding that furthers the understanding of human immunodeficiency virus (HIV), researchers from Children's Hospital Los Angeles discovered two locations where a single difference in HIV's genetic code altered the way the virus infected the cell, thereby influencing the progression of the disease.

Dendritic cells of elite controllers able to recognize, mount defense against HIV

Investigators from Massachusetts General Hospital and the Ragon Institute of MGH, MIT and Harvard have added another piece to the puzzle of how a small group of individuals known as elite controllers are able to control HIV infection without drug treatment. The research team reports finding that dendritic cells of elite controllers are better able to detect the presence of HIV, which enables them to stimulate the generation of T cells specifically targeting the virus.

Transmitted HIV drug resistance is persistent but is not harming treatment responses in the UK

A study that looks at the genetic makeup of archived samples of drug-resistant HIV in the UK has found evidence that some drug-resistant strains of HIV are

Some chimpanzees infected with AIDS virus may harbor protective, humanlike gene

When Peter Parham’s postdoc first showed him data suggesting a gene in some wild chimpanzees infected with the AIDS virus closely resembled one that protects humans from HIV, he was skeptical.

Acute HIV infection may present in many ways – sometimes as a serious illness

A Swiss study of people who were diagnosed during early HIV infection has found that a quarter of them presented or developed a wide variety of non-typical

Six questions about HIV/AIDS that deserve more attention

As HIV investigators work to control and eradicate the virus worldwide, certain myths or misconceptions about the disease have been embraced, whereas other concepts with merit have been left relatively unexplored, argues American HIV/AIDS researcher Jay Levy, M.D., in a Trends in Molecular Medicine commentary. He calls on fellow researchers to continue questioning and not to lose sight of alternative strategies that could ultimately lead to a sustainable, long-term solution to HIV infection.

HIV spreads like internet malware and should be treated earlier

A new model for HIV progression finds that it spreads in a similar way to some computer worms and predicts that early treatment is key to staving off AIDS. HIV specialists and network security experts at UCL noticed that the spread of HIV through the body using two methods -- via the bloodstream and directly between cells -- was similar to how some computer worms spread through both the internet and local networks respectively to infect as many computers as possible.

HIV can spread early, evolve in patients' brains

HIV can genetically evolve and independently replicate in patients' brains early in the illness process, an analysis of cerebral spinal fluid has found. Prompt diagnosis and treatment with antiretroviral therapy should reduce the risk that the virus could find refuge and cause damage in the brain, where some medications are less effective -- potentially enabling it to re-emerge, even after it is suppressed in the periphery, say researchers.

Inflammation and gut leakage remains elevated in people with HIV despite early antiretroviral treatment

Inflammatory changes and damage to the gut begin very soon after initial HIV infection, and may not return to normal even when people start antiretroviral therapy (ART)
