  • Potential New HIV Therapy Seen in Component of Immune Cells

    A research team led by Weill Cornell Medical College scientists has discovered a way to limit replication of the most common form of HIV at a key moment when the infection is just starting to develop. The study, published June 25 in Nature Communications, has shed light on a potential new element of human immunity against HIV-1 and could provide a powerful new strategy — perhaps as part of an HIV vaccine — to limit the severity of the disease.

  • Life as an Elite HIV Controller

    After finding out that I was an elite controller, I felt a lot of confusion. I knew what an elite controller was, but that didn’t translate to knowing what it actually meant to be one. I wasn’t new to the HIV world—I had previously been involved in HIV research—but I felt like I knew nothing about what was going on in my own body.

  • 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.

  • 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 Persists Despite Very Early HIV Treatment

    Biomarkers of inflammation increase during acute HIV infection and remain elevated despite early suppressive antiretroviral therapy, according to a study presented at CROI 2015, in Seattle, Washington.

  • Fast-replicating HIV strains drive inflammation and disease progression

    The results confirmed the team's previous finding that the replicative capacity of the newly established virus drives how quickly infected individuals' levels of CD4 T cells declined. People infected with viruses with high replicative capacity had more signs of acute inflammation in the first few months of infection. Their T cells displayed more signs of "exhaustion," which sets the stage for faster disease progression.

  • HIV vaccines should avoid viral target cells, primate model study suggests

    Vaccines designed to protect against HIV can backfire and lead to increased rates of infection. This unfortunate effect has been seen in more than one vaccine clinical trial. Scientists at Yerkes National Primate Research Center, Emory University, have newly published results that support a straightforward explanation for the backfire effect: vaccination may increase the number of immune cells that serve as viral targets.

  • Could HIV make hearing worse?

    A new study has found that low- and high-frequency hearing is poorer in adults with the human immunodeficiency virus, compared with adults who do not have the disease. Although unexpected, similar hearing loss has previously been observed to be more likely in adults with diabetes mellitus. "It is possible that both HIV infection and diabetes, being systemic diseases, could affect the neural function of the cochlea," the authors suggest.
