Intestinal tuft cells divide to make new cells when immunological cues trigger them. Additionally, in contrast to progenitor- and stem cells, tuft cells can survive severe injury such as irradiation ...

The immune system exercises constant vigilance to protect the body from external threats--including what we eat and drink. A careful balancing act plays out as digested food travels through the ...

The intestinal epithelium undergoes rapid renewal every 3–5 days, a process driven by intestinal stem cells (ISCs) located at the base of crypts. While ISCs play an essential role in epithelial ...

MIT scientists have found that an amino acid called cysteine can help the gut heal itself. In mouse studies, a cysteine-rich diet activated immune cells that release a molecule speeding up tissue ...

The terms "intestinal barrier" and "intestinal permeability" describe two different aspects of the same anatomical structure, the intestinal wall composed of four layers, the mucosa, the submucosa, ...

A key pressure-sensing protein involved in intestinal movement and inflammation regulation has been identified. Researchers from Harvard Medical School (MA, USA) and the Icahn School of Medicine at ...

The human gut replaces its cells faster than any other tissue in the body. Every few days, fresh cells are produced by specialized stem cells that ...
