Project description:Intracerebral hemorrhage (ICH) induces alterations in the gut microbiota composition, significantly impacting neuroinflammation post-ICH. However, the impact of gut microbiota absence on neuroinflammation following ICH-induced brain injury remain unexplored. Here, we observed that the gut microbiota absence was associated with reduced neuroinflammation, alleviated neurological dysfunction, and mitigated gut barrier dysfunction post-ICH. In contrast, recolonization of microbiota from ICH-induced SPF mice by transplantation of fecal microbiota (FMT) exacerbated brain injury and gut impairment post-ICH. Additionally, microglia with transcriptional changes mediated the protective effects of gut microbiota absence on brain injury, with Apoe emerging as a hub gene. Subsequently, Apoe deficiency in peri-hematomal microglia was associated with improved brain injury. Finally, we revealed that gut microbiota influence brain injury and gut impairment via gut-derived short-chain fatty acids (SCFA).

Project description:Parkinson's disease (PD) is a common neurodegenerative disease in middle-aged and elderly people. The disorder of gut microbiota is involved in the pathophysiological process of various neurological diseases, and many studies have confirmed that gut microbiota is involved in the progression of PD. As one of the most effective methods to reconstruct gut microbiota, fecal microbiota transplantation (FMT) has been considered as an important treatment for PD. However, the mechanism of FMT treatment for PD is still lacking, which requires further exploration and can facilitate the application of FMT. As a model organism, Drosophila is highly conserved with mammalian system in maintaining intestinal homeostasis. In this study, there were significant differences in the gut microbiota of conventional Drosophila colonized from PD patients compared to those transplanted from normal controls. And we constructed rotenone-induced PD model in Drosophila followed by FMT in different groups, and investigated the impact of gut microbiome on transcriptome of the PD host. Microbial analysis by 16S rDNA sequencing showed that gut microbiota could affect bacterial structure of PD, which was confirmed by bacterial colonization results. In addition, transcriptome data suggested that gut microbiota can influence gene expression pattern of PD. Further experimental validations confirmed that lysosome and neuroactive ligand-receptor interaction are the most significantly influenced functional pathways by PD-derived gut microbiota. In summary, our data reveals the influence of PD-derived gut microbiota on host transcriptome and helps better understanding the interaction between gut microbiota and PD through gut-brain axis. The present study will facilitate the understanding of the mechanism underlying PD treatment with FMT in clinical practice.

Project description:Gut microbiota participates in diverse metabolic and homeostatic functions related to health and well-being. Individual variation in its composition depends on many factors including dietary factors. We profiled enzymatic activity of fecal microbiota in 63 healthy adult individuals using metaproteomics, and identified Bacteroides and Prevotella –derived microbial CAZy (carbohydrate-active) enzymes involved in glycan foraging. One particular profile with many Bacteroides-derived CAZy was identified in one-third of subjects (n=20), and it associated with high abundancy of Bacteroides in most subjects. In other subjects (n=8) with dietary parameters similar to former, microbiota showed intense expression of Prevotella-derived CAZy including exo−beta−(1,4)−xylanase, xylan-1,4−beta−xylosidase, alpha−L−arabinofuranosidase and several other CAZy belonging to glycosyl hydrolase families involved in digestion of complex plant-derived polysaccharides. This associated invariably with robust representation of Prevotella in gut microbiota, while subjects with intermediate representation of Prevotella showed no CAZy profile. Identification of Bacteroides- and Prevotella-derived CAZy in microbiota proteome and their association with robust differences in microbiota composition, the latter with exceptionally high Prevotella abundancy in the gut, are in evidence of individual variation in metabolic adaptation of gut microbiota with an impact on colonizing competence.

Project description:We have previously demonstrated that the gut microbiota can play a role in the pathogenesis of conditions associated with exposure to environmental pollutants. It is well accepted that diets high in fermentable fibers such as inulin can beneficially modulate the gut microbiota and lessen the severity of pro-inflammatory diseases. Therefore, we aimed to test the hypothesis that hyperlipidemic mice fed a diet enriched with inulin would be protected from the pro-inflammatory toxic effects of PCB 126.

Project description:The gut microbiota is a key environmental determinant of mammalian metabolism. Regulation of white adipose tissue (WAT) by the gut microbiota is a critical process that maintains metabolic fitness, while dysbiosis contributes to the development of obesity and insulin resistance (IR). However, how the gut microbiota controls WAT functions remain largely unknown. Herein, we show that tryptophan-derived metabolites produced by the microbiota control the expression of the miR-181 family in white adipocytes to regulate energy expenditure and insulin sensitivity. Moreover, we show that dysregulation of the microbiota-miR-181 axis is required for the development of obesity, IR, and WAT inflammation. Thus, our results indicate that regulation of miRNA levels in WAT by microbiota-derived cues is a central mechanism by which host metabolism is tuned in response to dietary and environmental changes. As MIR-181 is dysregulated in WAT from obese human individuals, the MIR-181 family may represent a potential therapeutic target to modulate WAT function in the context of obesity.

Project description:The aim of this project was to explore the role of gut microbiota in the development of small intestine. The gut microbiota from different groups was used to treat the mice for 1 or 2 weeks. Then the small intestine samples were collected. The RNA was used for the RNA-seq analysis to search the role of gut microbiota in the development of small intestine. Groups: IMA100 mean gut microbiota from Alginate oligosaccharide 100mg/kg treated mice; IMA10 mean gut microbiota from Alginate oligosaccharide 10mg/kg treated mice; IMC mean gut microbiota from control group mice (dosed with water); Sa mean dosed with saline (no gut microbiota). "1" mean dosed for 1 week, "2" means dosed for 2 weeks.
