  • Researchers Discover New Battleground for Viruses and Immune Cells
    Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them. An improved understanding of how the immune system operates during a viral ...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

  • Seeking Clues to How Tuberculosis Infects Cells
    Cornell researchers are using advanced genetic techniques to better understand the relationship between the bacteria that cause tuberculosis and the human immune system defense cells that engulf them. The researchers have discovered that unlike many bacterial pathogens, ...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

  • Human Antibodies that Block Human and Animal SARS Viruses Identified
    An international team of investigators has identified the first human antibodies that can neutralize different strains of the virus responsible for outbreaks of severe acute respiratory syndrome (SARS). The researchers used a mouse model and in vitro assays (lab tests) to ...More
