Scientists have uncovered a gut-specific epigenetic aging mechanism that links inflammation and iron imbalance to cancer risk and may be reversible.

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 ...

In vivo, the intestinal epithelium interacts with the neighboring environment through complex crosstalk, which involves components such as the immune system, tissue microenvironment, and gut microbes.

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 ...

Researchers found that the hormone oxytocin, known to be involved in regulating feeding and social behavior and until now to be produced mostly in the brain, is also produced in the human intestine.

Healthy digestion depends on a delicate balance of fluid in the gut. At the heart of that balance are epithelial cells, which line the intestinal wall and control how salt and water move in and out of ...
