Faecal transplants alleviated nerve pain in people with diabetes, suggesting gut bacteria may play a role in causing such pain


We may finally know why psychological stress worsens gut inflammation

26 May 2023

A pathway between the brain and the immune system discovered in mice could explain why prolonged stress can exacerbate inflammatory bowel disease

Chronic fatigue syndrome linked to lower levels of some gut bacteria

8 February 2023

People with chronic fatigue syndrome have less of a kind of gut bacteria that produces inflammation-fighting molecules, suggesting a possible target for new treatments

All moral rights asserted. Recolouring or alteration of the image is prohibited without permission. Light micrograph of a section through a duodenum, the beginning of the small intestine, which runs from the stomach to the large intestine. It is where digestion begins and nutrients are absorbed into the blood. The interior (lumen, left) is lined with villi, which are folds in the intestinal surface that greatly increase the surface area for absorption. Also within the surface are crypts of Lieberkuhn (red-lined ovoids), which secrete enzymes into the lumen that help to digest the food. Underlying this layer is the muscularis mucosae (thin violet line) and connective tissue (blue). Across bottom are layers of smooth muscle and then circular and longitudinal muscles that contract and relax to move food through the duodenum.
