  • Researchers Identify New Source of Powerful Immunity Protein
    Researchers at UT Southwestern Medical Center report the identification of a new cellular source for an important disease-fighting protein used in the body’s earliest response to infection. The protein interferon-gamma (IFN-γ) keeps viruses from replicating and stimulates ...More

  • Immunity Mechanism Discovered by Scientists
    Scientists at the University of Calgary's Faculty of Medicine have discovered a mechanism that is used to protect the body from harmful bacteria. Platelets, a component of blood typically associated with clotting, were discovered to actively search for specific bacteria, ...More

  • Researchers Shed Light on How Immune Cells Detect Infections
    How do immune cells manage to sort through vast numbers of similar-looking proteins within the body to detect foreign invaders and fight infections? "For immune cells, singling out foreign proteins is like looking for a needle in a haystack – where the needle may look very ...More

  • Study Shows How Immune System Peacefully Co-exists With Good Bacteria
    The human gut is loaded with commensal bacteria – "good" microbes that, among other functions, help the body digest food. The gastrointestinal tract contains literally trillions of such cells, and yet the immune system seemingly turns a blind eye. However, in several ...More

  • Pathogen-Fighting 'Innate' Cells Could Revolutionize Immunizations
    New Cornell University research shows that small populations of pre-programmed immune cells can fight specific pathogens that they have never encountered. The findings, published in the Journal of Immunology, have the potential to revolutionize how and when people are ...More

  • Vaccine Adjuvant Uses Host DNA to Boost Pathogen Recognition
    Aluminum salts, or alum, have been injected into billions of people as an adjuvant to make vaccines more effective. No one knows, however, how they boost the immune response. In the March 19, 2013, issue of the Proceedings of the National Academy of Sciences researchers at ...More

  • Innate Immune System Can Kill HIV When a Viral Gene is Deactivated
    Human cells have an intrinsic capacity to destroy HIV. However, the virus has evolved to contain a gene that blocks this ability. When this gene is removed from the virus, the innate human immune system destroys HIV by mutating it to the point where it can no longer ...More
