  • Tracking How HIV Disrupts Immune System Informs Vaccine Development
    One of the main mysteries confounding development of an HIV vaccine is why some people infected with the virus make the desired antibodies after several years, but a vaccine can't seem to induce the same response. A research team led by scientists at the Duke Human Vaccine ...More

  • Penn Study Models How the Immune System Might Evolve to Conquer HIV
    It has remained frustratingly difficult to develop a vaccine for HIV/AIDS, in part because the virus, once in our bodies, rapidly reproduces and evolves to escape being killed by the immune system. "The viruses are constantly producing mutants that evade detection," said ...More

  • How Tumor Necrosis Factor Protects Against Infection
    Tumor necrosis factor (TNF), a messenger substance in the immune system, plays an important role in triggering chronic inflammatory diseases. For this reason, TNF inhibitors are a standard form of treatment for patients with rheumatoid arthritis and certain inflammatory ...More

  • Study Shows How Genes Affect Immunity in Response to Pathogens
    A study that is first in its kind and published in Nature Medicine today has looked at how far genetic factors control the immune cell response to pathogens in healthy individuals. A team investigated the response of immune cells from 200 healthy volunteers when stimulated ...More

  • Key Difference in Immune Cells May Explain Children's Increased Susceptibility to Illness
    Schools are commonly known as breeding grounds for viruses and bacteria, but this may not necessarily be linked to hygiene. New research in mice shows that because their immune systems do not operate at the same efficiency as adults, children may not only be more likely to ...More

  • Strengthening Immune Defense May Be Solution for Treating Tuberculosis
    Researchers at Linköping University have made a discovery that could contribute to developing new vaccines and treatment alternatives for tuberculosis in the future. The results have been published in Scientific Reports. Eight million people suffer from -- and 2 ...More

  • Super-Resolution Microscopy Reveals Unprecedented Detail of Immune Cells' Surface
    When the body is fighting an invading pathogen, white blood cells--including T cells--must respond. Now, Salk Institute researchers have imaged how vital receptors on the surface of T cells bundle together when activated. This study, the first to visualize this process in ...More

  • Immune Cells in the Lung Keep Legionella at Bay
    Immunologists and microbiologists from the University of Melbourne's Bio21 Molecular Science and Biotechnology Institute and the Peter Doherty Institute for Infection and Immunity -- a joint venture between the University of Melbourne and Royal Melbourne Hospital -- have ...More

  • Flu-Like Symptoms in Pregnant Women Could Affect Babies
    Babies born to mothers whose immune systems had to grapple with a viral assault -- even a mild one -- have increased risk of brain and central nervous system abnormalities, according to a new study. A USC-led team of researchers examined how the immune systems of pregnant ...More

  • Novel Role for Spleen B Cells in Inflammatory Response to Bacterial Toxins
    The inability to adequately respond to infection can cause a whole-body state of inflammation known as sepsis. This can eventually lead to systemic inflammatory response syndrome (SIRS), and even death. White blood cells known as B lymphocytes (B cells) produce antibodies ...More
