A silent signaling network deep in the gut protects against inflammatory intestinal disorders, scientists find
Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are listening and signaling. When ...
Why chronic pain lasts longer in women: Immune cells offer clues
Chronic pain lasts longer for women than men, and new research suggests differences in hormone-regulated immune cells, called monocytes, may help explain why.
