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 ...

A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune ...

Eating is one of life’s few constants: If you’re not eating right now, you’ll certainly be eating something within a few hours. But when and how often we should eat is still not fully understood.

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 ...

Gut support cells communicate with surprising precision – like brain neurons – using tiny extensions to send instructions to the stem cells responsible for maintaining and healing the intestine. The ...

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 ...

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 ...

The trillions of microbes in our gastrointestinal tract, known as the gut microbiome, are crucial to the body; the gut microbiome aids in digestion, nutrient absorption, and influences our health in ...
