New Northwestern Medicine research published in Nature Communications suggests that a metabolite produced by gut bacteria when they digest dietary fiber can leave a lasting molecular imprint on intestinal cells, promoting immune tolerance and protecting against inflammatory bowel disease-like conditions long after exposure ends.

Yingzi Cong, Ph.D., the Stanley Gradowski Professor of Gastroenterology and a professor of Microbiology-Immunology and Pathology, was the senior and co-corresponding author of the study.

Investigators describe the findings as evidence that beneficial microbial metabolites may be able to “train” the intestinal lining to maintain immune tolerance over time.

The origin of neurodegenerative diseases like Alzheimer’s or dementia isn’t limited to the brain. The state of your gut can quietly set off a cycle of chronic, system-wide inflammation that nudges the brain toward cognitive decline. But how does the pathogenesis of a disease that seems purely brain-based begin in the gut—an organ that is mostly busy producing chemicals for digesting food?

It turns out these two entities are linked by the gut-brain axis, a two-way communication superhighway that constantly sends signals between the digestive tract and the central nervous s...

In a new study using AI and machine learning, EPFL researchers have found that it’s not only what we eat, but how consistently we eat it that plays a crucial role in gut health.

The gut microbiota is the community of microorganisms, including bacteria, viruses, fungi and other microbes, that lives in our digestive systems—some of these microbes are helpful and others can be harmful.

Many previous studies have shown that what we eat has an impact on our gut microbiota...

Chronic kidney disease (CKD) is a major health issue worldwide. Many patients end up requiring regular dialysis to avoid kidney failure and stay alive. Despite the severity of the condition, there are currently no drugs available that improve kidney function.

A research group led by Tohoku University Graduate School of Medicine’s Professor Takaaki Abe has found a remarkable solution to treat patients with CKD by co-opting a drug typically used for constipation...
