  • Scientists Discover Switch to Boost Antiviral Response to Fight Infectious Diseases
    Singapore scientists from Bioprocessing Technology Institute (BTI) under the Agency of Science, Technology and Research have, for the first time, identified the molecular ‘switch’ that directly triggers the body’s first line of defense against pathogens, more accurately ...More

  • Biosignatures Distinguish Between Tuberculosis and Sarcoidosis
    The human immune system in action. This colored scanning electron microscope image shows a white blood cell (dyed red) in the act of destroying tuberculosis bacteria (yellow). The bacteria are surrounded by the cell membrane of the scavenger cell, then drawn inside and ...More

  • Studies Reveal How Cells Distinguish Between Disease-Causing and Innocuous Invaders
    The specific mechanisms by which humans and other animals are able to discriminate between disease-causing microbes and innocuous ones in order to rapidly respond to infections have long been a mystery to scientists. But a study conducted on roundworms by biologists at UC ...More

  • Rare Immune Cells Could Hold Key to Treating Immune Disorders
    The characterization of a rare immune cell’s involvement in antibody production and ability to ‘remember’ infectious agents could help to improve vaccination and lead to new treatments for immune disorders, say researchers from the Walter and Eliza Hall Institute. ...More

  • HIV 'Superinfection' Boosts Immune Response
    Women who have been infected by two different strains of HIV from two different sexual partners – a condition known as HIV superinfection – have more potent antibody responses that block the replication of the virus compared to women who’ve only been infected once. These ...More

  • Why Getting Healthy Can Seem Worse Than Getting Sick
    A new article in the Quarterly Review of Biology helps explain why the immune system often makes us worse while trying to make us well. The research offers a new perspective on a component of the immune system known as the acute-phase response, a series of systemic changes ...More

  • Study Uncovers How Salmonella Avoids the Body's Immune Response
    UC Irvine researchers have discovered how salmonella, a bacterium found in contaminated raw foods that causes major gastrointestinal distress in humans, thrives in the digestive tract despite the immune system’s best efforts to destroy it. Their findings help explain why ...More

  • Tonsils Make T-Cells, Too, Ohio State Study Shows
    A new study provides evidence that a critical type of immune cell can develop in human tonsils. The cells, called T lymphocytes, or T cells, have been thought to develop only in the thymus, an organ of the immune system that sits on the heart. The study, led by researchers ...More

  • Research Sheds Light on How Immune System Targets Infection
    University of Texas Medical Branch at Galveston researchers have discovered previously unsuspected aspects of the guidance system used by the body's first line of defense against infection. The new work focuses on the regulation of immune response by two forms of the ...More

  • Concept of Tolerance to Infection Could Create New Strategies to Treat Infectious Diseases
    The immune system protects from infections by detecting and eliminating invading pathogens. These two strategies form the basis of conventional clinical approaches in the fight against infectious diseases. In the latest issue of the journal Science, Miguel Soares from the ...More
