  • 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

  • Zinc Helps Against Infection by 'Tapping the Brakes' in Immune Response
    New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even deadly. Scientists determined in human cell culture and animal studies that a ...More

  • Immune Cell Suicide Alarm Helps Destroy Escaping Bacteria
    Cells in the immune system called macrophages normally engulf and kill intruding bacteria, holding them inside a membrane-bound bag called a vacuole, where they kill and digest them. ...More
