The intestinal immune system monitors the body’s largest interface with the environment. It must prevent adverse responses to ingested material, while protecting itself from harm, constraining the ...
Like hot dogs and hamburgers, shrimp cocktails are indelibly associated with summer, bringing a refreshing element to any picnic or cookout. Just strip the shell off, dip in the bowl of red cocktail ...
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.
Researchers at the Francis Crick Institute have shown that the Cryptosporidium parasite exports a protein into infected intestinal cells, altering the gut environment and enabling the parasite to ...
Researchers have found that the small intestine grows in response to pregnancy in mice. This partially irreversible change may help mice support a pregnancy and prepare for a second. Researchers at ...
The vertebrate intestine is well known for its regenerative capacity, but existing research emphasizes the role of a crypt–villus axis in the constant turnover of the intestinal epithelium. Mechanisms ...
A human intestinal organoid, displaying typical ‘budding crypts’ and a central ‘villus-like’ domain. The main intestinal cell types are shown in green, blue, red and purple. Membranes are yellow and ...
This story is part of a series exploring human anatomy and physiology complexities. Each story in this collection showcases discoveries reshaping our understanding of the body's inner workings, ...
In addition to protecting the host from pathogenic microbes, immune cells perform noncanonical physiological functions which require tissue-specific adaptation. Eosinophils are immune cells that are ...
