A recent study comparing young and aged mouse intestinal tissues revealed a delicate balance between IFN-γ signaling and ERK/MAPK signaling as crucial for maintaining the intestinal stem cell ...

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers at the University of Helsinki have discovered a new mechanism of action between the ...

Ever notice that as you get older, some foods no longer sit with you the same? This could be due to a breakdown of the ...

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 ...

Using human intestinal organoids, scientists uncovered a previously unknown immune function of M cells. By presenting gluten ...

If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to ...

A team led by scientists at King's College London, in collaboration with national and international partners, has discovered ...

If we could listen to stem cells closely enough, we might hear them whisper, “mechanosenses tingling.” After all, stem cells sense and react to the physical forces around them, maintaining their ...
