Gut microbiome plays a crucial role in modulation of inflammatory and immune pathways. Diverse bacterial species from gut microbiota feed on specific prebiotics (non-digestible dietary fibers) producing metabolites, such as short chain fatty acids (SCFA). These metabolites beneficially affect the intestinal mucosa with their role in metabolic and immunologic homeostasis, and gut barrier integrity. Recently gut-biome modulation and use of metabolites gained interest as potential targets for therapeutic development, for instance in Inflammatory Bowel Disease (IBD) which includes Crohn’s disease (CD) and ulcerative colitis (UC).
