  • 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

  • Scientists Find Ethnicity is Linked to Antibodies
    Cracking the DNA code for a complex region of the human genome has helped 14 North American scientists, including five at Simon Fraser University, chart new territory in immunity research. They have discovered that a good number of our antibody genes, how well they operate ...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

  • Declaring a Truce with Our Microbiological 'Frenemies'
    Managing bacteria and other microorganisms in the body, rather than just fighting them, may be lead to better health and a stronger immune system, according to a Penn State biologist. Researchers have historically focused on microbes in the body as primarily pathogens that ...More

  • Immune Cells Cluster and Communicate Like Bees, Researcher Discovers
    The immune system’s T cells, while coordinating responses to diseases and vaccines, act like honey bees sharing information about the best honey sources, according to a new study by scientists at UC San Francisco. “In the morning, each bee goes looking individually for a ...More

  • Scientists Study How Immune Cells are Able to Advance Their Own Evolution
    Immune system B cells play a crucial role in the defence of pathogens; when they detect such an intruder, they produce antibodies that help to combat the enemy. They concurrently and continuously improve these molecules to more precisely recognize the pathogens. A team of ...More

  • Scientists Discover How Deadly Bacteria Trick the Immune System
    An outbreak of tuberculosis in the skid row area of downtown Los Angeles may have exposed up to 4,500 individuals to the bacterium that causes the deadly disease and has left federal officials scrambling to intervene. The outbreak is occurring during winter, when homeless ...More
