Immune System

  • Biophysics Plays Key Role in Immune System Signaling and Response
    How big you are may be as important as what you look like, at least to immune system cells watching for dangerous bacteria and viruses. The size of pathogenic particles and the density of the molecular information stored on them provides additional danger signals to the ...More

  • NIH Scientists Identify Early Impact of Ebola Virus on Immune System
    A new mouse model of early Ebola virus (EBOV) infection has shown National Institutes of Health (NIH) scientists and colleagues how early responses of the immune system can affect development of EBOV disease. The model could help identify protective immune responses as ...More

  • Persistent Infection Keeps Immune Memory Sharp, Leading to Long-Term Protection
    Many infectious diseases are one and done; people get sick once and then they are protected from another bout of the same illness. For some of these infections - chickenpox, for example - a small number of microbes persist in the body long after the symptoms have gone away. ...More

  • Researchers Discover That T Cells Play a Crucial Role in Control of Zika Infections
    The worst of the global Zika virus outbreak may be over but many key questions remain, such as why the virus persists in certain tissues after the systemic infection has cleared; how does the immune system counteract the virus and protect against reinfection; what ...More

  • Sunlight Energizes Infection-Fighting T Cells
    Georgetown University Medical Center researchers have found that sunlight, through a mechanism separate than vitamin D production, energizes T cells that play a central role in human immunity. Their findings, published today in Scientific Reports, suggest how the skin, the ...More

  • Researchers Map Genome-Wide Changes That Drive T Cell Maturation and Exhaustion
    In a bid to better understand the gene expression patterns that control T cell activity, researchers at the La Jolla Institute for Allergy and Immunology mapped genome-wide changes in chromatin accessibility as T cells respond to acute and chronic virus infections. Their ...More

  • Important Element of Immune Defense Against Fungal Infections is Discovered
    Fungal infections are a serious health risk. They can be harmful especially to patients whose immune system is compromised through illness or chemotherapy. A team working at the Technical University of Munich (TUM) has discovered an important mechanism in the body's ...More

  • Scientists Discover How the Immune System Targets TB
    Every 18 seconds someone dies from tuberculosis (TB). It is the world's most deadly infectious disease. Mycobacterium tuberculosis, the causative agent of TB, has infected more than one-third of the entire human population with an annual death toll of approximately 1.5 ...More

  • UTMB Researchers Discover How Ebola Disables the Immune System
    A new study from researchers at the University of Texas Medical Branch in Galveston sheds light on how Ebola so effectively disables the human immune system. Virologist Alex Bukreyev, UTMB professor and senior author of the study, said the research team engineered versions ...More

  • Immune System Cells Cause Severe Malaria Complication in Mouse Model
    Immune system cells known as cytotoxic T cells attack blood vessels and cause fatal swelling in the brains of mice with a condition that mirrors a severe complication of malaria in humans. These are the findings of a new study published in PLOS Pathogens. ...More
