The innate immune system detects invasive pathogens and activates defense mechanisms to eliminate them. Pathogens, however, employ a variety of tricks to block this process. A new study shows how the measles virus thwarts the system, by means of a simple hairpin-like structure. The innate immune system is the body´s first line of defense against invasive pathogens and noxious chemicals. Essentially the system consists of an array of receptors that recognize particular molecular...

A Kansas State University-led study has uncovered new information that helps scientists better understand the complex workings of cells in the innate immune system. The findings may also lead to new avenues in disease control and prevention. Philip Hardwidge, associate professor of diagnostic medicine and pathobiology, was the study's principal investigator. He and colleagues looked at the relationship between a bacterial protein and the innate immune system -- a system of defensive cells...

IFIT antiviral protein recognizes foreign RNA and blocks viral infections Researchers at McGill University and the Research Center for Molecular Medicine (CeMM) of the Austrian Academy of Sciences have discovered the molecular blueprint behind the IFIT protein. This key protein enables the human immune system to detect viruses and prevent infection by acting as foot soldiers guarding the body against infection. They recognize foreign viral ribonucleic acid (RNA) produced by the virus and...

Influenza curbs part of the immune system and abets bacterial infections When infected with influenza, the body becomes an easy target for bacteria. The flu virus alters the host's immune system and compromises its capacity to effectively fight off bacterial infections. Now, a team of immunologists at the Helmholtz Centre for Infection Research (HZI) and cooperation partners has discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral...

Researchers Identify How Mosquito Immune System Attacks Specific Infections Researchers at the Johns Hopkins Bloomberg School of Public Health have determined a new mechanism by which the mosquitoes´ immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene. Unlike humans and other animals, insects do not make antibodies to target specific infections. According to the Johns Hopkins...

Key protein's double wing-like crystal structure captures secreted molecules from invading pathogens, activating the body's powerful immune response Researchers at Weill Cornell Medical College have unlocked the structure of a key protein that, when sensing certain viruses and bacteria, triggers the body's immediate immune response. In the journal Molecular Cell, scientists describe the double wing-like crystal structure of this key protein, known as STING, which is a soldier on the...

Good Bugs Gone Bad: Beneficial Microbes Kept In Their Place By Gut Immune Cells
2012-06-06 12:57:26

Good microbes that promote normal health can 'turn bad' if found outside the intestine The healthy human intestine is colonized with over 100 trillion beneficial, or commensal, bacteria of many different species. In healthy people, these bacteria are limited to the intestinal tissues and have a number of helpful properties, including aiding in the digestion of food and promoting a healthy immune system. However, when it comes to commensal bacteria, location is key. While commensal...
