Project description:We report that colonic lamina propria anti-inflammatory macrophages from Il10rb-/- (KO) mice at 12 weeks possessed significantly high levels of proinflammatory transcripts compared to the ones from Il10rb+/- (het) controls. While the transcriptional profile between macrophages from KO and het mice was comparable at 1 weeks and did not possess significant levels of proinflammatory transcripts, we show that the macrophages from KO mice were enriched for proinflammatory transcripts at 3 weeks compared to the ones from 3 week old het controls. These data indicate that the anti-inflammatory signature of colonic lamina propria macrophages from Il10rb-/- mice is compromized at 3 weeks.

Project description:The intestinal immune system must elicit robust immunity against harmful pathogens but restrain immune responses directed against commensal microbes and dietary antigens. The mechanisms that maintain this dichotomy are poorly understood. Here we describe a population of CD11b+F4/80+CD11câ?? macrophages in the lamina propria (LP) that express several anti-inflammatory molecules including interleukin 10 (IL-10), but little or no pro-inflammatory cytokines, even upon stimulation with Toll-like receptor (TLR) ligands. These macrophages induced, in a manner dependent on IL-10, retinoic acid and exogenous transforming growth factor-β, differentiation of FoxP3+ regulatory T cells. In contrast, LP CD11b+ dendritic cells elicited IL-17 production. This IL-17 production was suppressed by LP macrophages, indicating that a dynamic interplay between these subsets may influence the balance between immune activation and tolerance. Splenic or small intestine lamina propria CD11b+11c- cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. We sought to determine the unique genetic profile of small intestine lamina propria CD11b+11c- cells. Experiment Overall Design: 4 samples analyzed, 2 spleen and 2 intestine

Abstract:
Clostridium difficile infections are associated with the use
of broad-spectrum antibiotics and result in an exuberant
inflammatory response, leading to nosocomial diarrhea, colitis
and even death. To better understand the dynamics of mucosal
immunity during C. difficile infection from initiation through
expansion to resolution, we built a computational model of the
mucosal immune response to the bacterium. The model was
calibrated using data from a mouse model of C. difficile
infection. The model demonstrates a crucial role of T helper 17
(Th17) effector responses in the colonic lamina propria and
luminal commensal bacteria populations in the clearance of C.
difficile and colonic pathology, whereas regulatory T (Treg)
cells responses are associated with the recovery phase. In
addition, the production of anti-microbial peptides by inflamed
epithelial cells and activated neutrophils in response to C.
difficile infection inhibit the re-growth of beneficial
commensal bacterial species. Computational simulations suggest
that the removal of neutrophil and epithelial cell derived
anti-microbial inhibitions, separately and together, on
commensal bacterial regrowth promote recovery and minimize
colonic inflammatory pathology. Simulation results predict a
decrease in colonic inflammatory markers, such as neutrophilic
influx and Th17 cells in the colonic lamina propria, and length
of infection with accelerated commensal bacteria re-growth
through altered anti-microbial inhibition. Computational
modeling provides novel insights on the therapeutic value of
repopulating the colonic microbiome and inducing regulatory
mucosal immune responses during C. difficile infection. Thus,
modeling mucosal immunity-gut microbiota interactions has the
potential to guide the development of targeted fecal
transplantation therapies in the context of precision medicine
interventions.

Project description:Purpose: The goals of this study are to confirm the hypothesis that E4BP4 regulates colon specific anti-inflammatory macrophage. Methods: We generated transgenic mice (TG) with macrophage-specific E4BP4 overexpression. CD45+ cells in colon lamina propria were isolated at Zeitgeber Time (ZT) 0 from TG mice and WT littermates during the recovery period of dextran sulfate sodium (DSS)-induced colitis, and total RNA was extracted. CD45+ cells in colon lamina propria RNA profiles were generated by deep sequencing for two groups with one mouse sample each. Results: There were significant differences between TG and WT mice. Conclusions: E4BP4 increased the number of M2 macrophage population and upregulated anti-inflammatory genes.
