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 ...

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 ...

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 ...

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 ...

Smoking's not often touted for its health benefits. But it's been known to help those suffering from colitis even though it exacerbates Crohn's disease. New research that could help treat the ...

The human gut is home to trillions of bacteria that play vital roles in digestion, immunity, and overall health. Disruption of the interaction between the gut microbiome and the host can contribute to ...

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 ...

Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to ...
