A new molecular guardian of intestinal stem cells

Intestinal stem cells hold a fine balance between two potential forms: remaining as stem cells, or developing into intestinal epithelial cells. In a new study, researchers from Tokyo Medical and Dental University (TMDU) discovered ...

Intestinal cells stave off bacteria by purging

Though purging is not prescribed as often as it was centuries ago, intestinal cells known as enterocytes frequently resort to this age-old remedy. Researchers from the Immune Response and Development in Insects (CNRS), Molecular ...

Molecular docking site of a bacterial toxin identified

Clostridium difficile is a dangerous intestinal bacterium that can cause severe diarrhoea and life-threatening intestinal infections after long-term treatment with antibiotics. The pharmacologists and toxicologists Prof. ...

Researchers define a new type of secretory cell in the intestine

The intestinal epithelium consists of four main specialized cell lineages: absorptive enterocytes and three secretory cell types known as enteroendocrine, Paneth, and goblet cells. But a rare, fifth type of intestinal cell ...
