  • New Defense Mechanism Against Viruses Discovered
    Researchers have discovered that a known quality control mechanism in human, animal and plant cells is active against viruses. They think it might represent one of the oldest defense mechanisms against viruses in evolutionary history. When it comes to defense against ...More

  • Discovery Reveals How Bacteria Distinguish Harmful Versus Helpful Viruses
    When they are not busy attacking us, germs go after each other. But when viruses invade bacteria, it doesn’t always spell disaster for the infected microbes: Sometimes viruses actually carry helpful genes that a bacterium can harness to, say, expand its diet or better ...More

  • Keeping Viruses at Bay
    Our immunosensory system detects viruses such as influenza via specific characteristics of viral ribonucleic acid. Previously, it was unclear how the immune system prevents viruses from simply donning molecular camouflage in order to escape detection. An international team ...More

  • Novel Mechanism for Invasion of EV71 Virus is Demonstrated by Scientists
    Enterovirus 71 (EV71) is the major causative agent of hand, foot and mouth disease (HFMD) in the Asia-Pacific region, having caused 8.8 million infections and 3,000 deaths in China in the past five years. Unlike other enteroviruses (e.g. Coxsackievirus), EV71 can cause ...More
