A new study reveals that age-related changes in the gut microbiota directly impair intestinal stem cell (ISC) function and that restoring a youthful microbial environment can reverse this decline.

Although the gut renews itself constantly, its stem cells accumulate age-related molecular changes that quietly alter how ...

Scientists in Zlín are developing an advanced model of the human small intestine. The main goal behind this effort is to ...

In mouse models, scientists at Cincinnati Children's and Ulm University in Germany show that transferring microbiota from young mice to older mice rejuvenates intestinal stem cell function and speeds ...

The immune system exercises constant vigilance to protect the body from external threats--including what we eat and drink. A careful balancing act plays out as digested food travels through the ...

A key pressure-sensing protein involved in intestinal movement and inflammation regulation has been identified. Researchers from Harvard Medical School (MA, USA) and the Icahn School of Medicine at ...

Transverse colon samples from confirmed Alzheimer’s disease cases showed distinct gut microbiome and proteomic shifts, ...

Fat—adipose tissue—is more complicated than might be thought. Once considered just a bag of calories, scientists now know that fat doesn’t just squirrel away energy, it also sends and receives ...

The terms "intestinal barrier" and "intestinal permeability" describe two different aspects of the same anatomical structure, the intestinal wall composed of four layers, the mucosa, the submucosa, ...

Researchers find that tiny plastic particles increase the absorption of environmental arsenic and pesticides in lettuce and human intestinal cells, raising new safety concerns about plastic pollution.
