  • 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

  • HIV Vaccine Research Must Consider Various Immune Responses
    Last year, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, held a scientific meeting to examine why certain investigational HIV vaccines may have increased susceptibility to HIV infection. In a new perspectives ...More

  • Study Finds Novel Population of Neutrophils
    Case Western Reserve University researchers have discovered a novel population of neutrophils, which are the body’s infection control workhorses. These cells have an enhanced microbial killing ability and are thereby better able to control infection. Neutrophils, the ...More
