New Developments in the Role of Lactobacillus Reuteri in Regulating Intestinal Barrier Function

The intestinal barrier plays a role in maintaining the stability of the intestinal environment, which relies on the dynamic regulation of the intestinal microbiota. Lactobacillusreuteri (L.reuteri) is a lactic acid bacterium reported to be naturally present in the intestines of almost all vertebrates and mammals, and has been shown to affect the function of the intestinal barrier and safeguard the health of body through various pathways. This paper reviews the role and possible mechanisms of action of L.reuteri in regulating intestinal physical, chemical, immune and microbial barrier functions, with the aim of providing a theoretical basis and new ideas for the clinical application of L.reuteri in treating related diseases.
