  • 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.

  • Starting HIV Meds Within a Year of Infection Helps Restore CD4s

    Beginning treatment for HIV within a year of infection improves the likelihood of returning an individual’s CD4 count to a normal level.

  • HIV virulence depends on where virus inserts itself in host DNA

    The human immunodeficiency virus (HIV) can insert itself at different locations in the DNA of its human host -- and this specific integration site determines how quickly the disease progresses, report researchers at KU Leuven's Laboratory for Molecular Virology and Gene Therapy. The study was published online today in the journal Cell Host & Microbe.

  • The genetics of coping with HIV

    We respond to infections in two fundamental ways. One is 'resistance,' where the body attacks the invading pathogen and reduces its numbers. Another, which is much less well understood, is 'tolerance,' where the body tries to minimize the damage done by the pathogen. A study using data from a large Swiss cohort of HIV-infected individuals gives us a glimpse into why some people cope with HIV better than others.

  • Immune cells proposed as HIV hideout don't last in primate model

    The type of immune cell called macrophages, which have been proposed as a 'sanctuary site' of HIV in the brain and other organs, and as a possible cause of HIV-related brain impairment, don't live long enough to serve as reservoirs of HIV, a study in PLoS Pathogens finds.

  • HIV's infection tactics could guide AIDS vaccine, study finds

    New research that sheds light on the methods and machinery used by HIV to infect cells provides insight into the tricky virus that potentially could guide the development of a vaccine against the virus that causes AIDS, according to U.S. government and other scientists.
