Bacteria use multiple defense mechanisms to survive in the host body. Shigella bacteria that cause colitis disable multiple host defense pathways using three specialized effector proteins, as reported ...

Researchers have identified a gut-genetic interaction that could trigger an overactive immune response in the colon — offering one possible explanation for the pain and bleeding of ulcerative colitis, ...

A toxin produced by bacteria found in dirty water kills off immune cells in the lining of the colon, meaning people whose guts are colonised by these bacteria are much more likely to develop a ...

Microspheres that sense gastrointestinal disease are suspended in solution (L), and then attracted to the side of a test tube by a magnet (R) so researchers can easily retrieve them from biological ...

Move over, colonoscopies — researchers report in ACS Sensors that they’ve developed a sensor made of tiny microspheres packed with blood-sensing bacteria that detect markers of gastrointestinal ...

Diagram showing the mechanism discovered in the study. Inflammation of the intestines in ulcerative colitis results from an excessive helper Th2 immune response. Smoking leads to aromatic compounds ...

Bacteria "pills" that can detect gut diseases could spell the end of painful colonoscopies, scientists say. Chinese researchers have developed a new sensor made of tiny microspheres packed with ...

In most people, these bacteria coexist peacefully and contribute to a mutually beneficial relationship, with both human and bacteria deriving important benefits from the other. In certain individuals, ...
