Project description:Purpose: The aim of this study was to explore whether differences exist and to what an extent of the immune-mediated inflammatory reactions between periodontitis and peri-implantitis at the transcriptional level in the same susceptible host. Methods: Ligature-induced experimental peri-implantitis and periodontitis in the same mice were established. Gingival tissues of healthy, periodontitis and peri-implantitis sites from the same oral cavity were collected and used for RNA-sequencing. Differentially expressed genes (DEGs) were screened between periodontitis/peri-implantitis sites and healthy sites. The enrichment analysis of DEGs were analyzed. Comprehensive immune landscape was annotated by seq-ImmuCC. Results: The results showed that 137 and 353 up-regulated DEGs as well as and 670 and 174 down-regulated DEGs were specifically expressed periodontitis/peri-implantitis group compared to the healthy control group, respectively. The pathways of complement and coagulation cascade and osteoclast differentiation were dominating in the peri-implantitis sites. Moreover, peri-implantitis sites exhibited elevated macrophage proportions and relatively enriched macrophage activation and bone loss compared with periodontitis. Conclusions: Results indicated that peri-implantitis and periodontitis exhibited significantly distinct transcriptional signatures. Additionally, the study suggests that the interplay between macrophages and bone resorption are comparatively more active in peri-implantitis compared with periodontitis. These biological processes may be factors contributing to the pathogenesis of peri-implantitis being distinct from that of periodontitis.

Project description:This study included 20 participants (10 healthy subjects and 10 patients with periodontitis and peri-implantitis). Gingival tissue samples (10 healthy, 10 periodontitis, and 10 peri-implantitis tissues) were collected, RNAs were extracted, and RNA sequencing and analysis were performed.

Project description:Peri-implantitis is a common complication characterized by chronic inflammation of the periodontal tissue. This disease is marked by irreversible and progressive degradation of the gingiva and alveolar bone, ultimately leading to tooth loss.Most current research has focused on the entire periodontal tissue, which restricts a comprehensive understanding of the heterogeneity between gingiva and bone tissues, and hinders the development of targeted host therapies for peri-implantitis. To uncover the pathogenic mechanisms of peri-implantitis, our study employed a tissue-specific approach to investigate the interactions between stromal and immune cells in gingiva and bone tissues separately, using single-cell sequencing techniques. This strategy aims to develop the insights of the pathogenesis of peri-implantitis, providing a scientific basis for the treatment of peri-implantitis.

Project description:Objectives: The aim of this study was to identify the long noncoding RNAs (lncRNAs) and mRNAs that influence the different manifestations of peri-implantitis and periodontitis (I vs. P). Materials and methods: Gingival tissues from 6 peri-implantitis patients, 6 periodontitis patients, and 6 healthy individuals were analysed using lncRNAs and mRNAs gene expression microarrays. A lncRNAs subgroup analysis, a lncRNAs cluster graph, gene ontology (GO), and a pathway analysis of mRNAs were performed to analyse the data extracted from microarrays. To verify the results of the microarray studies, quantitative real-time polymerase chain reaction (qRT-PCR) was used to assess some differentially expressed lncRNAs and mRNAs. Results: In the gene expression microarray studies, 1,079 differentially expressed lncRNAs and 1,003 differentially expressed mRNAs were identified when comparing I vs. P. The lncRNAs subgroup analysis showed that there were 9 significantly up-regulated antisense lncRNAs and 18 significantly down-regulated antisense lncRNAs when comparing I vs. P. GO analysis on mRNAs revealed that the cyclooxygenase pathway is the most prominent signal among the up-regulated transcripts (3 genes) and that hemidesmosome assembly represents the most significant biological process among the down-regulated transcripts (4 genes) when comparing I vs. P. The expression levels of antisense lncRNA GACAT2 and mRNA MTCL1, antisense lncRNA MSC-AS1 with its sense mRNA MSC and TRPA1 were verified by RT-qPCR. Conclusions: Results indicated that peri-implantitis and periodontitis exhibit significantly different lncRNAs and mRNAs expression profiles. Additionally, specific lncRNAs may take part in the pathogenesis mechanisms of peri-implantitis and periodontitis through influencing their nearby mRNAs.

Project description:Transcriptome analysis of oral tissue samples taken from peri-implantitis and healthy control patients Peri-implantitis is a condition resulting in destructive inflammation in the peri-implant soft tissue barrier. Clinically, it demonstrates vast clinical differences to periodontitis that suggests distinct inflammatory mechanisms. Implant-derived Titanium particles (i-TiPs) frequently found around diseased implants appear to alter the microenvironment and confer resistance to antibiotic treatments. Studies in orthopedic implants have demonstrated a strong inflammatory response to i-TiPs, involving a variety of cell types, in aseptic conditions. Nonetheless, the genetic programs of cells surveilling and supporting the peri-implant soft tissue barrier in response to the combined challenges of biomaterial degradation products and oral bacteria are poorly defined. Thus, we studied gene expression specific to oral peri-implant inflammatory disease. We found that certain cellular pathways were highly upregulated in diseased tissues. Upregulated pathways provided insight into important physiological pathways that might play a role in peri-implant pathology. These findings could potentially contribute to the production of more targeted and effective therapeutics for the disease.

Project description:The peri-implant epithelium plays an important role in the prevention against initial stage of inflammation. In order to minimize the risk of peri-implantitis, it is necessary to understand the biological characteristics of the peri-implant epithelium. The aim of this study was to investigate the characteristic gene expression profile of peri-implant epithelium as compared to junctional epithelium using laser microdissection and microarray analysis.

In order to minimize the risk of peri-implantitis, it is necessary to understand the biological characteristics of the peri-implant epithelium. The aim of this study was to investigate the characteristic gene expression profile of peri-implant epithelium as compared to junctional epithelium using laser microdissection and microarray analysis. Left upper first molars of 4 week-old rat were extracted, and titanium alloy implants were placed. Four weeks after surgery, samples were harvested by laser microdissection, and total RNA samples were isolated. Comprehensive analyses of genes expressed in the junctional epithelium and peri-implant epithelium were performed using microarray analysis. Confirmation of the differential expression of selected genes was performed by quantitative real-time polymerase chain reaction and immunohistochemistry.
