  • 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

  • Deadly Virus Strips Away Immune Defensive Measures
    When the alert goes out that a virus has invaded the body, cells that have yet to be attacked prepare by "armoring" themselves for combat, attaching specific antiviral molecules to many of their own proteins to help resist the invader. These antiviral molecules aren't ...More

  • Immune Compound Blocks Virus' Hijacking of Antibodies
    Researchers at Washington University School of Medicine in St. Louis have shown that a controversial phenomenon known as antibody-dependent enhancement (ADE) of infection is suppressed by C1q, a bloodborne immune system compound. The link may give researchers the lead they ...More

  • New Data About the Impact of the Shingles Virus on Healthy Adults
    When a vaccine to prevent shingles was approved for use in 2006, the Food and Drug Administration (FDA) recommended the vaccine for people age 60 and older who previously had chickenpox. But two issues -- the vaccine’s cost and the perception that shingles primarily affects ...More
