Neutrophil extracellular traps trigger inflammatory bone destruction in periodontitis

Project description:Neutrophil recruitment and activation are hallmarks of the prevalent inflammatory disease, periodontitis. However, the mechanisms by which neutrophils contribute to in inflammatory bone destruction remain unclear. Herein, we document that neutrophil extracellular traps (NETs) have a direct role in mediating inflammatory pathology. In an established animal model of periodontitis, we demonstrate that genetic or pharmacologic inhibition of NETs formation, or removal of NETs by DNase-Ⅰ, alleviates inflammatory bone loss in vivo. Investigating the mechanisms by which NETs drive periodontal inflammation, we find that extracellular histones have a direct role in disease progression. Consistent with findings in animal models, histones bearing classic NET-associated post-translational modifications are correlated with disease severity and are significantly elevated in local lesions and systemic circulation of patients with periodontitis. Our work reveals NETs-associated components as pathogenic mediators, potential biomarkers, and therapeutic targets for periodontitis.

Inflammation and neutrophil extracellular traps in cerebral cavernous malformation

Project description:Cerebral Cavernous Malformation (CCM) is a brain vascular disease with various neurological symptoms. In this study, we describe the inflammatory profile in CCM and show for the first time the formation of neutrophil extracellular traps (NETs) in rodents and humans with CCM. Through RNA-seq analysis of cerebellum endothelial cells from wild-type mice and mice with anendothelial cell-specific ablation of the Ccm3 gene (Ccm3iECKO), we show that endothelial cells from Ccm3iECKO mice have anincreased expression of inflammation-related genes.

Ulcerative colitis aggravates periodontitis via myeloid skewing of hematopoietic progenitor cell differentiation

Project description:Objective Ulcerative colitis (UC) is a risk factor of periodontitis. This study aimed to investigate whether hematopoietic stem and progenitor cells (HSPCs) and their myeloid progeny exacerbate periodontal inflammation in UC. Design Ligature-induced periodontitis (LIP) was established in dextran sulfate sodium (DSS)-induced colitis (DIC) C57BL/6 mice. The bone resorption, intestinal and periodontal inflammation were evaluated by micro-CT and histological analyses. Inflammatory cytokines and lipopolysaccharide (LPS) in serum and gut microbiota were assessed by multiplexed flow cytometric assay, ELISA and 16S rRNA sequencing, respectively. Flow cytometry was performed to analyze HSPCs differentiation, and to sort hematopoietic stem cells for transcriptomic analysis. Berberine treatment of DIC was employed to investigate whether dampening of DIC would alleviate periodontitis. Results DIC mice exhibited disrupted intestinal barrier with dysbiotic gut microbiota, corroborating the elevated serum level of LPS and IL-1. Compared to DIC-free/LIP mice, DIC/LIP mice showed aggravated alveolar bone resorption, with enrichment of neutrophils extracellular traps (NETs) in periodontal tissues. DIC promoted myelopoiesis of HSPCs by up-regulating myeloid differentiation pathway. Intragastric administration of berberine dampened DIC and rescued the myeloid skewing of HSPCs, consequently alleviating periodontal destruction. Intriguingly, LIP induction after DIC remission still exhibited aggravated periodontal destruction and myeloid skewing of HSPCs, indicating a UC-trained immunity against periodontal infection. Conclusion Increased gut permeability and microbial dysbiosis in UC elevate the serum level of LPS and IL-1, inducing myeloid skewing of HSPCs with an immune memory. Generation of inflammatory potential myeloid cells causes NETs accumulation and aggravates periodontal destruction in the UC-related periodontitis.
