  • 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.

  • Dynamic motion of HIV as it readies an attack: Seen in real time, for the first time

    Technologies that allow investigators, for the first time, to watch what they call the 'dance' of HIV proteins on the virus' surface, which may contribute to how the virus infects human immune cells, have been developed by scientists. The new technology platform opens new possibilities for devising an approach to prevent HIV infection, note researchers

  • Protein tethers HIV and Ebola to cells

    A family of proteins that helps viruses, such as HIV and Ebola, enter a cell also can block the release of those viruses. When HIV-1 or any virus infects a cell, it replicates and spreads to other cells. One type of cellular protein—T cell immunoglobulin and mucin domain, or TIM-1—has previously been shown to promote entry of some highly pathogenic viruses into host cells. Researchers have now discovered that the same protein possesses a unique ability to block the release of such viruses. The findings are published in the Proceedings of the National Academy of Sciences. “This is a surprising finding that provides new insights into our understanding of not only HIV infection, but also that of Ebola and other viruses,” says Shan-Lu Liu, associate professor of molecular microbiology and immunology at University of Missouri.

  • How HIV co-opts gut bacteria to pose as a familiar infection

    One of the most effective methods used by HIV to evade control is to hide from the immune system. B-cells are crucial for controlling new infections, producing specific antibodies to attack it, which coat the surface of infected cells and tag them for destruction. But according to a study from Duke Medicine, published in Cell Host & Microbe, when HIV enters and begins replicating in the gut, the reaction of B cells is ineffective because the virus is able to pose as a “good” bacterium. Its gp41 surface protein - which is displayed on the surface of infected cells - looks like surface proteins on the cells of friendly gut bacteria.

  • Gut flora influences HIV immune response

    Normal microorganisms in the intestines appear to play a pivotal role in how the HIV virus foils a successful attack from the body’s immune system, according to new research. "Gut flora keeps us all healthy by helping the immune system develop, and by stimulating a group of immune cells that keep bacteria in check," said the study's senior author. "But this research shows that antibodies that react to bacteria also cross-react to the HIV envelope."

  • Why the immune system fails to kill HIV

    Our immune system contains CD8+ T cells which protect us from various diseases such as cancer and viruses. Some of them are specifically tasked with killing cells infected with the HIV virus – and researchers from Karolinska Institutet, together with international colleagues, have for the first time identified a key explanation for why these cells are unsuccessful in their task. In simple terms, the immune system's ignition keys have not been turned all the way to the start position, which would enable the CD8+ T cells to kill the cells infected with HIV.
