True to type: From human biopsy to complex gut physiology on a chip

The small intestine is the main site where we digest and absorb nutrients and minerals from food, and it is also a place where many intestinal infections occur and digestive and inflammatory disorders manifest themselves. To better understand the intestine in its normal and pathological states, researchers have created “organoids” by isolating intestinal stem cells from human biopsy samples. These ...

The fight against sepsis could get a helping hand from a surprising source: gut bacteria. Researchers reporting February 22 in the journal Cell Host & Microbe found that giving mice particular microbes increased blood levels of immunoglobulin A (IgA) antibodies, ...

Low-calorie diet enhances intestinal regeneration after injury

Dramatic calorie restriction, diets reduced by 40 percent of a normal calorie total, have long been known to extend health span, the duration of disease-free aging, in animal studies, and even to extend life span in most animal species examined. Further research has shown that animals fed restricted-calorie diets are also better able to regenerate numerous tissues after injury. A ...
