The gut microbiota plays a central role to modulate the plasma metabolome in response to chronic Angiotensin II infusion (part-II)

ABSTRACT: Six week old C57BL/6 conventional (mice with gut microbiota; conv, n=6) and germ-free (mice without gut microbiota; GF, n=6) mice were infused with angiotensin-II (AngII) for 4 weeks (400ng.kg-1.min-1; Alzet 1004). In parallel control groups, conv (n=6) and GF (n=6) mice received saline via minipumps. Our primary goal was to identify metabolites which were differentially regulated in conventional mice treated with AngII, but not in GF mice, indicating that these metabolites are microbial in origin. Following minipump implantation, animals were housed singly to prevent cross-contamination of microbiota. At the end of fourth week, feces and blood were collected. Both plasma and feces samples were processed and analyzed by using Liquid Chromatography-Tandem Mass Spectroscopy (LC-MS/MS) for metabolite detection (Metabolon).

The Key Role of Segmented Filamentous Bacteria in the Coordinated Maturation of Gut Helper T Cell Responses

Project description:Microbiota-induced cytokine responses participate in gut homeostasis, but the cytokine balance at steady-state and the role of individual bacterial species in setting the balance remain elusive. Using gnotobiotic mouse models, we provide a systematic analysis of the role of microbiota in the induction of cytokine responses in the normal intestine. Colonization by a whole mouse microbiota orchestrated a broad spectrum of pro-inflammatory (Th1, Th17) and regulatory T cell responses. Unexpectedly, most tested complex microbiota and individual bacteria failed to efficiently stimulate intestinal cytokine responses. A potent cytokine-inducing function was however associated with non-culturable host-specific species, the prototype of which was the Clostridia-related Segmented Filamentous Bacterium, and this bacterial species recapitulated the coordinated maturation of T cell responses induced by the whole mouse microbiota. Our study demonstrates the non-redundant role of microbiota members in the regulation of gut immune homeostasis. Germfree (GF) female 8-9-week-old mice were gavaged twice at a 24-hr interval with 0.5 mL of fresh anaerobic cultures of fecal homogenate from SFB mono-associated mice, fresh feces from Cv mice (Cvd) or from a healthy human donor (Hum). All mice were sacrificed on d8, 20 and 60 post-colonization in parallel to age-matched Cv and GF controls. RNA was extracted from ileal tissue, and processed to biotin-labelled cRNA, and then hybridized to the NuGO array (mouse) NuGO_Mm1a520177. Microarray analysis compared gene expression in ileum tissue of all the treatment groups GF, Cv, Cvd, Hum and SFB (N=3 per treatment group per time-point). Data was considered significant when P<0.05 using the Benjamini and Hochberg false discovery method.

Germfree C57BL/6J mice are resistant to high fat diet-induced insulin resistance and have altered cholesterol metabolism

Project description:Germfree (GF) mice have been used as a model to study the contribution of the intestinal microbiota to metabolic energy balance of the host. Despite a wealth of knowledge accumulated since the 1940’s, the response of GF mice to a high fat diet is largely unknown. In the present study, we compared the metabolic consequences of a high fat (HF) diet on GF and conventional (Conv) C57BL/6J mice. As expected, Conv mice developed obesity and glucose intolerance with a HF diet. In contrast, GF mice remained lean and resisted the HF diet-induced insulin resistance. The anti-obesity phenotype of GF/HF mice was accompanied by reduced caloric intake, diminished food efficiency, and excessive fecal lipid excretion contributed to the reduced food efficiency. In addition, HF diet-induced hypercholesterolemia was ameliorated, which was partially due to an increase in fecal cholesterol excretion. However, hepatic cholesterols were increased in GF/HF mice. Elevated nuclear SREBP2 proteins and the up-regulation of cholesterol biosynthesis genes support the increased liver cholesterol biosynthesis in GF/HF mice. The resistance to HF diet-induced metabolic abnormalities in GF mice was also associated with a reduced immune response, indicated by low plasma pro-inflammatory and anti-inflammatory markers. These data suggest that the gut microbiota of Conv mice contributes to HF diet-induced obesity, insulin resistance, dyslipidemia and hepatic steatosis in mice. Thus, results of the present study describe the metabolic responses of GF mice to a HF diet and further our understandings of the relationship between the gut microbiota and the host. Germfree and conventional C57BL/6J mice were fed with a high fat diet for 11 weeks. Then, all mice were sacrified under 10-h food deprevation, and liver samples of germfree (n=14) and conventional (n=16) were examined.

Gender bias in autoimmunity is influenced by microbiota

Project description:Gender bias and the role of sex hormones in autoimmune diseases are well established. In specific-pathogen free (SPF) non-obese diabetic (NOD) mice females have 1.3-4.4 times higher incidence of Type 1 diabetes (T1D). Germ-free (GF) mice lose the gender bias (female/male ratio 1.1-1.2). Gut microbiota differed in males and females, a trend reversed by male castration, confirming that androgens influence gut microbiota. Colonization of GF NOD mice with defined microbiota revealed that some but not all lineages overrepresented in male mice supported a gender bias in T1D, and protection did not correlate with androgen levels. However, hormone-supported selective microbial lineage variation may work as a positive feedback mechanism contributing to the sexual dimorphism of autoimmune diseases. Gene expression analysis suggested pathways involved in protection of males from T1D by microbiota. We compared gene expression patterns in the pancreatic lymph nodes (PLNs) between four groups of mice (two genders in SPF and GF conditions, respectively). PLNs were isolated from 9-10 week old GF and SPF male and female NOD mice with 3 mice in each group, for a total of 12 samples.

Transcriptional Modulation of Genes by Gut Microbiota in Germfree and Conventional Mice

Project description:To characterize the effect of microbiota on global gene expression in the distal small intestine during postnatal gut development we employed mouse models with experimental colonization by intestinal microbiota. Using microarray analysis to assess global gene expression in ileal mucosa at the critical stage of intestinal development /maturation associated with weaning, and asking how expression is affected by microbial colonization In the study presented here, preweaned and postweaned GF, SPF mouse small intestinal total RNAs were used. Also, 3-week-old gnotobiotic mouse as well as GF mouse small intestinal RNAs were used.

Expression data from Germ-Free (GF) and L.NK2-colonized mice intestinal epithelial cells and Peyer's patches cells

Project description:Lactobacillus NK2 (L.NK2) is a commensal microbe, isolated from the mouse intestinal feces in our lab. To examine the potential role of L. NK2 in the gut immunity, we monocolonized GF mice with L.NK2. And, we conducted a microarray experiment to compare the transcriptomes of GF and L.NK2-colonized mice intestines under the same experimental condition We used microarrays to detail the global programme of gene expression in intestinal epithelial cells (IEC) and Peyer's patches cells (PP) of GF and L.NK2-colonized mice.
