Irritable bowel syndrome (IBS) is an intestinal inflammatory disorder affecting 14.1% of the United States. Symptoms include abdominal pain, changes in the pattern of bowel movement and also impacts quality of life with psychological impacts including anxiety, major depression, and chronic fatigue syndrome. Introduction of probiotics has been shown to reduce symptoms of IBS, however no molecular basis for the benefits of probiotics has been elucidated.

Molecular Probiotic Interventions for the Treatment of IBS

One secreted soluble protein and one small molecule metabolite have been identified to combat visceral hypersensitivity & inflammation in IBS via restoration of gut permeability, and additionally restoring levels of anti-inflammatory molecules respectfully. Recombinant protein was shown to restore the permeability in human colonoids and restore the homeostasis of epigenetic proteins/markers.
