Immune Response


  • Potential New Flu Drugs Target Immune Response, Not Virus
    The seriousness of disease often results from the strength of immune response, rather than with the virus, itself. Turning down that response, rather than attacking the virus, might be a better way to reduce that severity, says Juliet Morrison of the University of ...More

  • Immune Function Predicts Infection Risk Among Child Trauma Patients
    Researchers studying critically ill children with traumatic injuries have identified an immune marker that predicts which patients are likely to develop a hospital-acquired infection. The study, led by clinician-scientists at Nationwide Children's Hospital and published ...More

  • Unsuspected Aspect of Immune Regulation is Revealed
    A discovery by Australian immunologists, uncovering an additional role for antibody-making B cells, is considered important enough by the American Association of Immunologists to rank it among the top 10 percent of articles in the latest issue of the Journal of ...More

  • Scientists Discover 'Invisibility Cloak' for Immune Cells
    The various cells in the immune system have to protect themselves from one another so that they don’t kill each other. Immune biologist Annette Oxenius and her team from ETH Zurich have now discovered a previously unknown mechanism that immune cells use to protect ...More

  • Molecule Regulates Production of Antibacterial Agent Used by Immune Cells
    Researchers have discovered how a protein molecule in immune cells promotes the production of nitric oxide, a potent weapon in the cells’ arsenal to defend the body from bacterial attack. The protein may offer a target for reining in the inflammatory response, which ...More

  • TB Dogma Upended: Even Uninfected Cells Trigger Immune Defenses
    Experimenting with mice, infectious disease experts at NYU Langone Medical Center have found that immune system cells uninfected with the bacterium that causes tuberculosis trigger immune system T cells to fight the disease. The findings upend the long-held scientific ...More

  • Dormant Viruses Re-Emerge in Patients with Lingering Sepsis, Signaling Immune Suppression
    A provocative study links prolonged episodes of sepsis — a life-threatening infection and leading cause of death in hospitals — to the reactivation of otherwise dormant viruses in the body. In healthy people, such latent viruses are kept in check by the immune ...More

  • Scientists Discover Immune System Precursor Cells That Fight Infection
    The innate immune system recognizes infectious agents such as viruses and bacteria. A group of lymphocytes known as "innate lymphoid cells" or ILCs plays a central role in the defense of the human body against infective agents. Professor Andreas Diefenbach of the Research ...More

  • 'Bystander' Chronic Infections Thwart Development of Immune Cell Memory
    Studies of vaccine programs in the developing world have revealed that individuals with chronic infections such as malaria and hepatitis tend to be less likely to develop the fullest possible immunity benefits from vaccines for unrelated illnesses. The underlying mechanisms ...More

  • Discovery Helps Explain How B Cells Adapt to Their Targets
    Over the weeks following an invasion by a disease-causing microbe, the human immune system fine tunes its defenses, producing proteins called antibodies that are ever more precisely targeted at the invader. New research in Michel Nussenzweig’s laboratory of molecular ...More
