New bacteria to fight against intestinal inflammation
Date:11/6/2012

in Lactococcus lactis and Lactobacillus casei, two food-grade bacteria found in dairy products.

Results in mice

When administered orally to mice, the human Elafin-producing bacteria are found a few hours later on the surface of the intestine where they deliver the anti-inflammatory protein. In different mice models of chronic or acute intestinal inflammation, oral treatment using these Elafin-producing bacteria provided significant protection of the intestine and decreased inflammatory symptoms.

and in humans

Elafin expressed by these bacteria also protects cultured human intestinal cell lines from inflammatory outbreaks similar to those observed in chronic inflammatory bowel diseases. Elafin produced in this way restores the equilibrium of intestinal mucus by reducing inflammation and accelerating cell healing processes.

Potential clinical applications

These results may result in a clinical application where Elafin would be administered to patients suffering from IBDs using beneficial bacteria (probiotic), which are already commonly found in food (yoghurt, cheese), thus protecting the patients from inflammatory symptoms. According to the researchers "This kind of secure treatment could even be used over the long-term, to treat inflammatory diseases."
