According to researchers, a type of dietary fibre called inulin, which is used in health supplements and have certain anti-inflammatory properties, can also pro
Scientists at Weill Cornell Medicine have developed a pipeline that will enable study of the biological roles of gut bacteria, recognized as key factors in health and disease.

The discovery of an “Achilles’ heel” in a type of gut bacteria that causes intestinal inflammation in patients with Crohn’s disease may lead to more targeted therapies for the difficult-to-treat disease, according to researchers at Weill Cornell Medicine and NewYork-Presbyterian.
In a study published Feb. 5 in Cell Host and Microbe, the investigators showed that patients with Crohn’s disease have an overabundance of a type of gut bacteria called adherent-invasive Escherichia coli (AIEC), which
promotes inflammation in the intestine. Their experiments revealed that a metabolite produced by the bacteria interacts with immune system cells in the lining of the intestine, triggering inflammation.

The discovery of an Achilles heel in a type of gut bacteria that causes intestinal inflammation in patients with Crohn s disease may lead to more targeted therapies for the difficult to treat disease, according to Weill Cornell Medicine and NewYork-Presbyterian investigators.
In a study published Feb. 3 in
Cell Host and Microbe, the investigators showed that patients with Crohn s disease have an overabundance of a type of gut bacteria called adherent-invasive Escherichia coli (AIEC), which promotes inflammation in the intestine. Their experiments revealed that a metabolite produced by the bacteria interacts with immune system cells in the lining of the intestine, triggering inflammation. Interfering with this process, by either reducing the bacteria s food supply or eliminating a key enzyme in the process relieved gut inflammation in a mouse model of Crohn s disease.
