Researchers at Karolinska Institutet have identified three types of nerve cells connected to the intestinal villi, suggesting that previously unknown neural networks regulate fluid balance in the gut.

In the gut, there is an enteric nervous system; it is a network of neurons that extends throughout the walls of the GI tract ...

Villi are small epithelial protrusions that serve to increase the surface area of the gut for efficient nutrient absorption. The mechanism of their formation during development was recently ...

These intestinal cells then migrate up the intestinal villi. During their migration, they perform a certain function, for example the absorption of nutrients or the production of hormones.

Understanding key neural networks in the gut “The study provides a unique insight into the appearance, gene expression, and communication of submucosal nerve cells with surrounding cells in the ...

Iron gets absorbed at the bottom of intestinal villi, in the crypts. As cells reach the villi tips, they can either release the iron they carry into the blood, or hold it until they die in the ...

Because sex and pregnancy hormones regulate RANK–RANKL signalling, we assessed the structure of intestinal villi — tiny, finger-like protrusions in the gut lining that provide a large surface ...
