Biologists Control Gut Inflammation by Altering the Abundance of Resident bacteria

 Proposed model of sox10 mutant intestinal pathology. sox10 mutants have altered intestinal motility and an increased bacterial load. Given the role of the ENS in intestinal function, sox10 mutants likely also experience alterations in epithelial secretion and permeability, although these phenotypes are yet to be examined. sox10 mutants can assemble a microbiota that mirrors WT intestinal microbiota (host population 2) or is dysbiotic (host population 1), characterized by an expansion of the Vibrio lineage and reduction of the Escherichia lineage. We do not yet know what determines which bacterial community assembles in sox10 mutants (dashed lines) but hypothesize that it could be due to the timing or order of exposure to bacterial strains, differences in epithelial permeability or secretion, or differences in other host compensatory mechanisms.
