Changes in gut microbiota induced by oral pathobiont deteriorate the pathology of non-alcoholic fatty liver disease

Project description:Periodontitis increases the risk of non-alcoholic fatty liver disease (NAFLD). However, the precise mechanisms are unclear. Here, gut dysbiosis induced by orally administered Porphyromonas gingivalis, a representative periodontopathic bacterium, was implicated in the deterioration of NAFLD pathology. C57BL/6 mice were administered with the vehicle, P. gingivalis or Prevotella intermedia, with weaker periodontal pathogenicity, followed by feeding on a choline-deficient, high fat diet (CDAHFD60). CDAHFD60 feeding induced hepatic steatosis, and combined bacterial administration further aggravated NAFLD pathology with increased fibrosis. Liver gene expression analyses revealed that genes involved in the NAFLD pathology were perturbed with distinctive expression profiles induced by different bacteria. These differences may be due to quantitative and qualitative differences in the influx of gut bacterial products because the serum endotoxin level, gut microbiota composition, and serum metabolite profile caused by ingested P. intermedia and P. gingivalis were different. These findings provide insights into mechanisms linking periodontitis and NAFLD.

9 human epithelial cell transcriptome sequencing analysis

Project description:We report the study of the mechanism of action of Porphyromonas gingivalis on human oral epithelial cells based on high-throughput sequencing technology. By acting Porphyromonas gingivalis and its metabolites on human oral epithelial cells separately, the mechanism of Porphyromonas gingivalis evading immune surveillance and causing local and deep tissue diffusion to induce systemic diseases was studied. This study provides a framework for studying the pathogenic mechanism of Porphyromonas gingivalis.

Effect of hmuY and hmuR or husA and husB genes deletion on Porphyromonas gingivalis gene expression

Project description:Porphyromonas gingivalis is one of the main etiological agents responsible for initiating and progressing periodontal diseases in humans. P. gingivalis does not synthesize heme, and it uses host hemoproteins as a source of this molecule. The main heme uptake mechanism utilized by P. gingivalis is the Hmu system composed of six proteins where HmuY (hemophore-like protein) and HmuR (TonB-dependant outer membrane heme receptor) play a crucial role in heme supply. The second heme uptake mechanism is the Hus system composed of four proteins, with HusA (hemophore-like protein) and HusB (TonB-dependant outer membrane receptor) supporting heme uptake. Heme and iron starvation influence the P. gingivalis phenotype, therefore the aim was to determine the influence of deletion of HmuY and HmuR (ΔhmuYR strain) or HusA and HusB (ΔhusAB strain) encoding genes on P. gingivalis gene expression.

Human AoSMCs stimulated by viable P. gingivalis

Project description:Porphyromonas gingivalis is a gram-negative bacterium that causes destructive chronic periodontitis. In addition, this bacterium is also involved in the development of cardiovascular disease. The aim of this study was to investigate the effects of P. gingivalis infection on gene and protein expression in human aortic smooth muscle cells (AoSMCs) and its relation to cellular function.
