Immune Response

  • Immune Response Differences Might Determine Severity of West Nile Virus Disease
    While most West Nile Virus (WNV) infections in humans are asymptomatic and go unnoticed, the virus causes serious and sometimes fatal neurologic illness in some people. A study published on January 21 in PLOS Pathogens suggests that an exaggerated and abnormal immune ...More

  • Innate Immune Defenses Triggered by Unsuspected Mechanism
    To the amazement of researchers in immunology and genetics, a previously unsuspected mechanism is activated in the presence of pathogens after only a few hours. "In the hours following an attack by bacteria, we observed the activation of thousand of genes in the cells of ...More

  • Surfing DNA: Enzyme Catches a Ride to Fight Infection
    Scientists have shown for the first time that an enzyme crucial to keeping our immune system healthy “surfs” along the strands of DNA inside our cells. The researchers used extremely powerful microscopy to watch how the enzyme AID (activation-induced ...More

  • Thrombosis During Sepsis is a Consequence of Protective Host Immune Responses
    Researchers from the University of Birmingham have, for the first time, identified how Salmonella infections that have spread to our blood and organs can lead to life-threatening thrombosis. These systemic infections trigger the development of inflammation, which in turn ...More

  • Self-Rated Health Predicts Immune Response to the Common Cold
    It turns out that we may be the best forecasters of our own health. New research from Carnegie Mellon University psychologists shows that a simple self-rating of health accurately predicts susceptibility to the common cold in healthy adults aged 18-55 years. Published in ...More
