Gut microbe compound Urolithin A may support intestinal lining repair
ScienceDaily reports that researchers identified a bacterial byproduct from foods like pomegranates that triggers protective gut repair pathways.
The short version
- University of Louisville researchers found that Urolithin A, a microbial metabolite derived from foods like berries and walnuts, activates a repair pathway in intestinal cells.[ScienceDaily]
- The compound selectively activates the aryl hydrocarbon receptor and the NLRP6 inflammasome, prompting protective mucus production and barrier repair in lab and patient tissue models.[ScienceDaily]
- Scientists suggest these findings could aid in developing targeted treatments for inflammatory bowel disease that restore gut balance instead of broadly suppressing immunity.[ScienceDaily]
- Clinical efficacy and practical therapeutic applications in living human patients remain unproven.[ScienceDaily]
Key facts
- Urolithin A is a microbial compound produced after consuming foods such as pomegranates, walnuts, and berries.[ScienceDaily]
- The compound activates the aryl hydrocarbon receptor in intestinal epithelial cells, which in turn triggers the NLRP6 inflammasome.[ScienceDaily]
- The mechanism was tested using cell studies, organoids, and IBD patient tissue samples.[ScienceDaily]
What remains uncertain
- The study relied on experimental models and patient tissue samples, meaning clinical benefits and effectiveness in human patients are not yet established.[ScienceDaily]
