  • UC Davis Researchers Discover How HIV Turns Food Poisoning into Lethal Infection
    SACRAMENTO, Calif. -- Nearly half of all HIV-positive African adults who become infected with Salmonella die from what otherwise would be a seven-day bout of diarrhea. Now, UC Davis School of Medicine scientists have discovered how salmonella becomes lethal for AIDS ...More

  • Nanoemulsion Vaccines Show Increasing Promise
    A novel technique for vaccinating against a variety of infectious diseases – using an oil-based emulsion placed in the nose, rather than needles – has proved able to produce a strong immune response against smallpox and HIV in two new studies. The results build on previous ...More

  • Immune System Protein Starves Staph Bacteria
    One of the ways we defend ourselves against bacterial foes is to “hide” their food, particularly the metals they crave. A multi-disciplinary team led by Vanderbilt University investigators has now discovered that a protein inside certain immune system cells blocks the ...More

  • Protein in Tick Saliva Prevents HIV-1 from Attaching to T Cells
    The HIV-1 virus cripples the human immune system by targeting white blood cells called T cells that form the body’s first line of defense in fighting infections. A recent study by researchers from the University of Massachusetts Amherst shows that a protein found in the ...More

  • Gene Chips Used to Distinguish Ventilator-Associated Pneumonia from Underlying Critical Illness
    Critically ill patients who need a ventilator to breathe face a high risk of pneumonia. The lung infection, however, is exceedingly difficult to diagnose because a patient's underlying condition often skews laboratory test results and masks pneumonia's symptoms – a reality ...More

  • Researchers Find Cell Protein That Nips HIV in the Bud
    UCLA researchers have found that a key protein in the body's dendritic cells can stop the virus that causes AIDS from "budding" — part of the virus' life cycle that is crucial to its ability to replicate and infect other cells. The study is scheduled for publication in the ...More
