Study TitleGut microbiome-derived metabolites modulate intestinal epithelial cell damage and mitigate graft-versus-host disease
Study SummaryTaxonomic alterations in the intestinal microbiota are being progressively associated with many diseases, including graft-versus host disease (GVHD). However, the impact of these alterations on microbial metabolites and by-products and their subsequent impact on disease processes, such as GVHD, are not known. Here we utilized a targetedn unbiased and blinded approach in a blinded fashion to identify novel alterations in the levels of microbial metabolites, specifically levels including the short chain fatty acid (SCFA) and endogenous histone deacetylase inhibitor (HDACi), butyrate, after allo-BMT. Surprisingly, alterations were observed only in intestinal epithelial cells (IECs) but not in the luminal contents. The reduced butyrate in IECs (CD326+) after allo-BMT resulted in decreased histone acetylation, which was restored upon local administration of exogenous butyrate. This resulted in improved IEC junctional integrity, increased anti-apoptotic proteins, decreased GVHD, and improved survival. Furthermore, alteration of endogenous microflora with 17 rationally selected strains of high butyrate producing Clostridia, also decreased GVHD and increased survival following allo-BMT in experiments performed at two different institutions. These data demonstrate an heretofore unrecognized role of microbial metabolites and suggests that local and specific alteration of microbial metabolites has direct salutary effects on GVHD target tissues and mitigates its severity.
