Cells on the inner surface of the intestine are replaced every few days. But, how does this work? It was always assumed that cells leave the intestinal surface because excess cells are pushed out. In ...

The mechanisms that compensate for the loss of intestinal stem cells after injury are poorly defined. There is a population of intestinal cells, called tuft cells, that do not normally divide. When ...

Organs don't just grow in early life; they can change in response to physiological or environmental challenges in adulthood. Researchers have now identified an active role for the intestinal muscles ...

Researchers have solved a cellular mystery that may lead to better therapies for colorectal and other types of cancer. A professor of pediatrics-developmental biology and an assistant professor of ...

What the research is about Our intestine has a remarkable ability to repair themselves after injury. However, when ...

Tuft cells are present throughout the intestinal tract as well as in many organs. Studies in mice have shown that when tuft cells sense the presence of pathogens, they signal to immune cells and to ...

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 ...

A new preclinical study from Weill Cornell Medicine found that the protein caspase-5 (CASP5), long thought to be a foot soldier in the body's defense against bacterial infection, does not actually ...

A new study reported in Nature has determined that the amino acid cysteine could promote regeneration among cells in the small intestine. The work showed that cysteine can activate an immune signaling ...

Researchers found that a small population of immune cells in the mouse intestine prevents allergic responses to food, suggesting that targeting such cells therapeutically could potentially lead to a ...

A research team led by scientists from the State University of Campinas (UNICAMP) in São Paulo, Brazil, has made significant progress in understanding the relationship between gut microbiota and ...
