Project description:Transcription profiling by array of intestinal epithelial cells (IECs) from mice with IEC-specific HDAC3 deletion against wild type controls

Project description:The development and severity of inflammatory bowel diseases (IBD) and other chronic inflammatory conditions can be influenced by host genetic and environmental factors, including signals derived from commensal bacteria. However, the mechanisms that integrate these diverse cues remain undefined. Here we demonstrate that intestinal epithelial cells (IECs) isolated from IBD patients exhibit decreased expression of the epigenome-modifying enzyme histone deacetylase 3 (HDAC3). Further, genome-wide analyses of murine IECs that lack HDAC3 (HDAC3ΔIEC) revealed that HDAC3 deficiency resulted in dysregulated gene expression coupled with alterations in histone acetylation. Critically, conventionally-housed HDAC3ΔIEC mice demonstrated loss of Paneth cells, impaired IEC function and alterations in the composition of intestinal commensal bacteria. In addition, HDAC3ΔIEC mice exhibited significantly increased susceptibility to intestinal damage and inflammation, indicating that epithelial expression of HDAC3 plays a central role in maintaining intestinal homeostasis. Strikingly, rederivation of HDAC3ΔIEC mice into germ-free conditions revealed that dysregulated IEC gene expression, Paneth cell homeostasis, and intestinal barrier function were largely restored in the absence of commensal bacteria. Collectively, these data indicate that the HDAC3 is a critical factor that integrates commensal bacteria-derived signals to calibrate epithelial cell responses required to establish normal host-commensal relationships and maintain intestinal homeostasis. In this study, we performed gene expression profiling to examine how the transcriptional profiles in primary live, EpCAM+ IECs from the large intestine differed between germ-free control HDAC3FF mice (3 biological replicates) and germ-free IEC-intrinsic knockout HDAC3ΔIEC mice (3 biological replicates).

Here we demonstrate that intestinal epithelial cells (IECs) isolated from IBD patients exhibit decreased expression of the epigenome-modifying enzyme histone deacetylase 3 (HDAC3). Further, genome-wide analyses of murine IECs that lack HDAC3 (HDAC3?IEC) revealed that HDAC3 deficiency resulted in dysregulated gene expression coupled with alterations in histone acetylation. Critically, conventionally-housed HDAC3?IEC mice demonstrated loss of Paneth cells, impaired IEC function and alterations in the composition of intestinal commensal bacteria. In addition, HDAC3?IEC mice exhibited significantly increased susceptibility to intestinal damage and inflammation, indicating that epithelial expression of HDAC3 plays a central role in maintaining intestinal homeostasis.

Project description:We report that adhesion of microbes to intestinal epithelial cells is a critical cue for Th17 induction. SFB colonized in the intestine of mice can adhere to mouse small intestinal epithelial cells and induce intestinal Th17 cells. However, SFB colonized in rats cannot adhere to mouse intestinal epithelial cells and induce Th17 cells. Likewise, Citrobacter rodentium (WT) can adhere to mouse colonic epithelial cells and induce Th17 cells, but non-adherent mutant of C. rodentium (Δeae) cannot induce Th17 cells. To examine the influence of adherent bacteria on intestinal epithelial cells, we performed RNA seq. Germ free mice were orally inoculated with M-SFB or R-SFB and total RNA was isolated from small intestinal epithelial cells 1 week after inoculation. Alternatively, germ free mice were orally inoculated with C. rodentium WT or eae mutant and total RNA was isolated from colonic epithelial cells 5 days after inoculation. The gene expression of small intestinal epithelial cells isolated from small intestine of germ free mice (2 mice), mice monocolonized with M-SFB (2 mice) or R-SFB (3 mice), and colon of germ free mice (3 mice), mice monocolonized C. rodentium WT (3 mice) or eae mutant (3 mice).
