Abstract
PURPOSE OF REVIEW To review the role of the immune cells and their interaction with cells found in gingiva, periodontal ligament, and bone that leads to net bone loss in periodontitis or bone remodeling in orthodontic tooth movement. RECENT FINDINGS Periodontal disease is one of the most common oral diseases causing inflammation in the soft and hard tissues of the periodontium and is initiated by bacteria that induce a host response. Although the innate and adaptive immune response function cooperatively to prevent bacterial dissemination, they also play a major role in gingival inflammation and destruction of the connective tissue, periodontal ligament, and alveolar bone characteristic of periodontitis. The inflammatory response is triggered by bacteria or their products that bind to pattern recognition receptors that induce transcription factor activity to stimulate cytokine and chemokine expression. Epithelial, fibroblast/stromal, and resident leukocytes play a key role in initiating the host response and contribute to periodontal disease. Single-cell RNA-seq (scRNA-seq) experiments have added new insight into the roles of various cell types in the response to bacterial challenge. This response is modified by systemic conditions such as diabetes and smoking. In contrast to periodontitis, orthodontic tooth movement (OTM) is a sterile inflammatory response induced by mechanical force. Orthodontic force application stimulates acute inflammatory responses in the periodontal ligament and alveolar bone stimulated by cytokines and chemokines that produce bone resorption on the compression side. On the tension side, orthodontic forces induce the production of osteogenic factors, stimulating new bone formation. A number of different cell types, cytokines, and signaling/pathways are involved in this complex process. Inflammatory and mechanical force-induced bone remodeling involves bone resorption and bone formation. The interaction of leukocytes with host stromal cells and osteoblastic cells plays a key role in both initiating the inflammatory events as well as inducing a cellular cascade that results in remodeling in orthodontic tooth movement or in tissue destruction in periodontitis.

J Periodontal Res 2020; 56:186-194. [PMID: 33247463 DOI: 10.1111/jre.12813] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Revised: 09/20/2020] [Accepted: 09/30/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND OBJECTIVE Traumatic occlusion can cause bone resorption without bacterial infection. Although bone resorption in periodontitis has been relatively well studied, little is known about bone resorption by traumatic occlusion. High-mobility group box 1 (HMGB1) is released from damaged tissue and has been recently shown to promote bone resorption in a murine periodontitis model and may also promote bone resorption by traumatic occlusion. The present study aimed to examine whether HMGB1 accelerates bone resorption by traumatic occlusion in mice. MATERIALS AND METHODS Occlusal trauma was induced in the lower left first molar of mice by bonding a wire to the upper left first molar, and bone resorption and osteoclast formation were evaluated histochemically. The expression of HMGB1, Toll-like receptor 4 (TLR4; the receptor for HMGB1), and receptor activator of NFκB ligand (RANKL; an essential osteoclast differentiation factor) was evaluated immunohistologically. In addition, mice were administrated with an anti-HMGB1-neutralizing antibody to analyze the role of HMGB1. RESULTS Bone resorption and osteoclast formation gradually increased until day 5 at the furcation area after the application of traumatic occlusion. Expression of HMGB1 was observed at the furcation area on day 1, but was attenuated by day 3. Expression of RANKL gradually increased until day 3, but was attenuated by day 5. Administration of anti-HMGB1 antibody significantly reduced the number of osteoclasts and the expression of RANKL and TLR4 at the furcation area. CONCLUSION Release of HMGB1 in the root furcation area accelerated bone resorption by up-regulating RANKL and TLR4 expression in mice with traumatic occlusion.

Abstract
Periodontitis is a chronic inflammatory disease with a complex underlying immunopathology. Cytokines, as molecular mediators of inflammation, play a role in all stages of disease progression. T helper 17 (Th17) cells are thought to play a role in periodontitis. Th17 cell development and maintenance requires a pro-inflammatory cytokine milieu, with many of the cytokines implicated in the pathogenesis of periodontitis. Serum and saliva are easily accessible biofluids which can represent the systemic and local environment to promote the development of Th17 cells. Here we review human clinical studies that investigate IL-1β, IL-4, IL-6, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, IFN-γ, sCD40L and TNF-α in serum and saliva in periodontitis. We highlight their putative role in the pathogenesis of periodontitis and place them within a wider context of animal and other clinical studies.

[PMID: 31763378 PMCID: PMC6861591 DOI: 10.1016/j.bonr.2019.100228] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2019] [Revised: 10/03/2019] [Accepted: 10/18/2019] [Indexed: 12/18/2022] Open
Abstract
ALA/SFC induced the activation of Nrf2 in osteoblasts. IL-6 and RANKL expression in osteoblasts was increased by LPS, but decreased by Nrf2 activation. LPS-mediated RANKL augmentation was dependent on IL-6 induction. Nrf2 activation in osteoblasts suppresses indirectly osteoclastogenesis via inhibiting the expression of IL-6.
Bone destructive diseases such as periodontitis and rheumatoid arthritis are caused by excessive activation of osteoclasts. Osteoclastogenesis is regulated by Receptor activator of nuclear factor kappa-β ligand (RANKL) produced by osteoclastogenesis supporting cells such as osteoblast and osteocyte. Previously, we reported that NF-E2-related factor-2 (Nrf2) activation in osteoclast precursors inhibited osteoclastogenesis and bone destruction via induction of anti-oxidation and thereby attenuated intracellular ROS signaling. However, it still remains unknown whether Nrf2 activation in cells other than osteoclasts give any negative influence on supporting property for osteoclastogenesis. Here we discovered that Nrf2 activation in osteoblasts suppresses indirectly osteoclastogenesis via inhibiting the expression of interleukin-6 (IL-6) which promotes osteoclastogenesis. In this study, 5-aminolevulinic acid hydrochloride (ALA) and sodium ferrous citrate (SFC) was used as the Nrf2 activator. in vitro experiments, using osteoblast cell line, MC3T3-E1, revealed that the expression of IL-6 was increased by LPS stimulation, but decreased after ALA/SFC treatment in mRNA and protein levels. Furthermore, RANKL expression was augmented by LPS, which was blocked by ALA/SFC treatment. Neutralizing antibody against IL-6 confirmed that LPS-mediated RANKL augmentation was dependent on IL-6 induction. in vivo experiments with LPS-mediated bone destruction in mice, confirmed that augmented IL-6 expression in osteoblasts by immunochemical analysis. ALA/SFC treatment attenuated LPS-mediated IL-6 upregulation. These results suggest that Nrf2 activation in osteoblasts suppress IL-6 and inflammatory bone destruction. The Nrf2 activator acts not only on osteoclasts but also on osteoblasts, in other word, Nrf2 activation indirectly suppresses osteoclastogenesis. In conclusion, the Nrf2 activator exhibits dual inhibitory effects via direct action on osteoclast and indirect action on osteoclast supporting cells.

Single Local Injection of Epigallocatechin Gallate-Modified Gelatin Attenuates Bone Resorption and Orthodontic Tooth Movement in Mice. Polymers (Basel) 2018; 10:polym10121384.

Abstract
Osteoclastic bone resorption enables orthodontic tooth movement (OTM) in orthodontic treatment. Previously, we demonstrated that local epigallocatechin gallate (EGCG) injection successfully slowed the rate of OTM; however, repeat injections were required. In the present study, we produced a liquid form of EGCG-modified gelatin (EGCG-GL) and examined the properties of EGCG-GL with respect to prolonging EGCG release, NF-E2-related factor 2 (Nrf2) activation, osteoclastogenesis inhibition, bone destruction, and OTM. We found EGCG-GL both prolonged the release of EGCG and induced the expression of antioxidant enzyme genes, such as heme oxygenase 1 (Hmox1) and glutamate-cysteine ligase (Gclc), in the mouse macrophage cell line, RAW264.7. EGCG-GL attenuated intracellular reactive oxygen species (ROS) levels were induced by the receptor activator of nuclear factor-kB ligand (RANKL) and inhibited RANKL-mediated osteoclastogenesis in vitro. An animal model of bone destruction, induced by repeat Lipopolysaccharide (LPS)-injections into the calvaria of male BALB/c mice, revealed that a single injection of EGCG-GL on day-1 could successfully inhibit LPS-mediated bone destruction. Additionally, experimental OTM of maxillary first molars in male mice was attenuated by a single EGCG-GL injection on day-1. In conclusion, EGCG-GL prolongs the release of EGCG and inhibits osteoclastogenesis via the attenuation of intracellular ROS signaling through the increased expression of antioxidant enzymes. These results indicate EGCG-GL would be a beneficial therapeutic approach both in destructive bone disease and in controlling alveolar bone metabolism.

Abstract
Periodontal disease (periodontitis) is a chronic inflammatory condition initiated by microbial infection that leads to gingival tissue destruction and alveolar bone resorption. The periodontal tissue's response to dental plaque is characterized by the accumulation of polymorphonuclear leukocytes, macrophages, and lymphocytes, all of which release inflammatory mediators and cytokines to orchestrate the immunopathogenesis of periodontal disease. Ubiquitination is achieved by a mechanism that involves a number of factors, including an ubiquitin-activating enzyme, ubiquitin-conjugating enzyme, and ubiquitin-protein ligase. Ubiquitination is a post-translational modification restricted to eukaryotes that are involved in essential host processes. The ubiquitin system has been implicated in the immune response, development, and programmed cell death. Increasing numbers of recent reports have provided evidence that many approaches are delivering promising reports for discovering the relationship between ubiquitination and periodontal disease. The scope of this review was to investigate recent progress in the discovery of ubiquitinated protein in diseased periodontium and to discuss the ubiquitination process in periodontal diseases.

Abstract
Reactive oxygen species (ROS) play a role in intracellular signaling during osteoclastogenesis. We previously reported that transcriptional factor nuclear factor E2-related factor 2 (Nrf2) was exported from the nucleus to the cytoplasm by receptor activator of nuclear factor-κB ligand (RANKL), and that Nrf2 negatively regulated osteoclastogenesis via antioxidant enzyme up-regulation. Knockout mice of BTB and CNC homology 1 (Bach1)-the competitor for Nrf2 in transcriptional regulation-was known to attenuate RANKL-mediated osteoclastogenesis, although the mechanism remains unclear. Therefore, we hypothesized that RANKL could be involved in the nuclear translocation of Bach1, which would attenuate Nrf2-mediated antioxidant enzymes, thereby augmenting intracellular ROS signaling in osteoclasts. RANKL induced Bach1 nuclear import and Nrf2 nuclear export. Induction of Bach1 nuclear export increased Nrf2 nuclear import, augmented antioxidant enzyme expression, and, thus, diminished RANKL-mediated osteoclastogenesis via attenuated intracellular ROS signaling. Finally, an in vivo mouse bone destruction model clearly demonstrated that induction of Bach1 nuclear export inhibited bone destruction. In this study, we report that RANKL favors osteoclastogenesis via attenuation of Nrf2-mediated antioxidant enzyme expression by competing with Bach1 nuclear accumulation. Of importance, induction of Bach1 nuclear export activates Nrf2-dependent antioxidant enzyme expression, thereby attenuating osteoclastogenesis. Bach1 nuclear export might be a therapeutic target for such bone destructive diseases as rheumatoid arthritis, osteoporosis, and periodontitis.-Kanzaki, H., Shinohara, F., Itohiya, K., Yamaguchi, Y., Katsumata, Y., Matsuzawa, M., Fukaya, S., Miyamoto, Y., Wada, S., Nakamura, Y.

Abstract
Interferons (IFNs) play essential roles in regulating osteoclast differentiation and bone resorption. Over the last decade, we have seen tremendous developments in our understanding of the mechanisms by which interferons regulate osteoclastogenesis. Of the type I interferons, IFN-β inhibits osteoclastogenesis via autoregulatory or exogenous regulatory mechanisms, while IFN-α was recently shown to participate in regulating osteoclast formation. And the only member of type II interferons, IFN-γ, has biphasic effects on osteoclastogenesis. Type III interferons have also been shown to be involved in osteoclast bone resorption, although no direct regulatory mechanism has been demonstrated. In this review, we provide an update account of the current knowledge on these recently revealed novel roles of interferons in the regulation of a variety of signaling pathways in osteoclast differentiation and function. The potential clinical applications are also discussed.

Abstract
It has been reported that reactive oxygen species (ROS) play a role as intracellular signaling molecules in RANKL stimulation. Previously we demonstrated that induction of cytoprotective enzyme expression by Nrf2-gene transfer successfully ameliorated RANKL-dependent osteoclastogenesis. In the present study, we hypothesized that Nrf2 activation by inhibiting ubiquitination and degradation of Nrf2 by ETGE-peptide would induce Nrf2-dependent cytoprotective enzyme expression, attenuate ROS signaling, and thereby inhibit RANKL-dependent osteoclastogenesis. ETGE-peptide containing a cell-permeable sequence (seven consecutive arginine; 7R-ETGE) was applied to a mouse macrophage cell-line RAW 264.7 cell or a primary macrophage culture. ETGE-peptide prevents Keap1 from binding to Nrf2. Nrf2 nuclear translocation and Nrf2-dependent cytoprotective enzyme induction was observed. The effects of 7R-ETGE on RANKL-dependent induction of intracellular ROS levels and osteoclastogenesis were examined. Finally, the protective effect of 7R-ETGE on RANKL-mediated bone destruction was investigated in mice. 7R-ETGE dose-dependently induced nuclear Nrf2, followed by the induction of cytoprotective enzyme expression at both the gene and protein level. 7R-ETGE inhibited upregulation of intracellular ROS levels by RANKL stimulation, and osteoclastogenesis was attenuated. Of particular interest was that local injection of 7R-ETGE ameliorated RANKL-mediated bone destruction. Local induction of nuclear Nrf2 by protein transduction is a potential novel therapeutic target for bone destruction diseases such as periodontitis and rheumatoid arthritis.

Abstract
OBJECTIVE LPS can induce differentiation to osteoclast-like cells independent of RANKL. In comparison with RANKL, the effects of Th1 and Th2 cytokines on LPS-induced osteoclastogenesis have not been extensively studied. In this study, we investigated the effects of IFN-γ and IL-4 on RANKL- or LPS-induced osteoclastogenesis. MATERIALS AND METHODS RAW 264.7 cells were induced to differentiate into osteoclast-like cells by RANKL or LPS, in the absence or presence of IFN-γ or IL-4. The number of TRAP-positive, multinucleated (≥ 3 nuclei) cells (MNCs) was counted. mRNA and protein levels of TRAP and cathepsin K were determined by quantitative RT-PCR and Western immunoblot, respectively. Expression of other genes implicated in osteoclast and macrophage differentiation and inflammation was also quantitated and was subsequently assessed in bone marrow-derived macrophages (BMMs). Phagocytic capacity of differentiated RAW264.7 was investigated by the uptake of pHrodo S. aureus bioparticles conjugates. RESULTS In contrast to the RANKL-treated cell population that gained more macrophage-like properties at the level of gene and protein expression as well as phagocytosis in the presence of IFN-γ or IL-4, the LPS-induced population gained more osteoclast-like properties by the addition of the same factors. CONCLUSION These data suggest that the adaptive immune system, through either Th1 or Th2 cytokines, is able to modify the differentiation process of osteoclasts in inflammatory situations. Moreover, the study provides an example of different regulation of osteoclast differentiation during physiological and inflammatory conditions.

Abstract
Reactive oxygen species (ROS) act as intracellular signaling molecules in the regulation of receptor activator of nuclear factor-κB ligand (RANKL)-dependent osteoclast differentiation, but they also have cytotoxic effects that include peroxidation of lipids and oxidative damage to proteins and DNA. Cellular protective mechanisms against oxidative stress include transcriptional control of cytoprotective enzymes by the transcription factor, nuclear factor E2-related factor 2 (Nrf2). This study investigated the relationship between Nrf2 and osteoclastogenesis. Stimulation of osteoclast precursors (mouse primary peritoneal macrophages and RAW 264.7 cells) with RANKL resulted in the up-regulation of kelch-like ECH-associated protein 1 (Keap1), a negative regulator of Nrf2. It also decreased the Nrf2/Keap1 ratio, and it down-regulated cytoprotective enzymes (heme oxygenase-1, γ-glutamylcysteine synthetase, and glucose-6-phosphate dehydrogenase). Nrf2 overexpression up-regulated the expression of cytoprotective enzymes, decreased ROS levels, decreased the number of tartrate-resistant acid phosphatase-positive multinucleated cells, reduced marker genes for osteoclast differentiation, and attenuated bone destruction in both in vitro and in vivo models. Overexpression of Keap1 or RNAi knockdown of Nrf2 exerted the opposite actions. In addition, in vivo local Nrf2 overexpression attenuated lipopolysaccharide-mediated RANKL-dependent cranial bone destruction in vivo. This is the first study to show that the Keap1/Nrf2 axis regulates RANKL-dependent osteoclastogenesis through modulation of intracellular ROS signaling via expression of cytoprotective enzymes. This raises the exciting possibility that the Keap1-Nrf2 axis may be a therapeutic target for the treatment of bone destructive disease.

Abstract
Interferon gamma (IFNγ) has been reported to induce osteoblastogenesis from mesenchymal stem cells (MSCs) both in vitro and in vivo. With ageing, adipocytes outnumber osteoblasts within the bone microenvironment leading to a decrease in bone formation. Since both osteoblasts and adipocytes are of mesenchymal origin, we hypothesized that IFNγ treatment might negatively affect adipogenesis while stimulating osteoblastogenesis in human MSC. To test this hypothesis, human MSCs were induced to differentiate into adipocytes in the presence or absence of osteogenic doses of IFNγ (1, 10, and 100 ng/ml). IFNγ-treated MSC showed a decrease in adipocyte differentiation and lipid deposition when compared with vehicle-treated controls. Additionally, adipogenic markers were significantly decreased by IFNγ treatment at the same doses that have been reported to have a strong osteogenic effect in vitro. Furthermore, DNA binding of peroxisome proliferator-activated receptor gamma was significantly lower in IFNγ-treated differentiating MSC. Subsequently, ovariectomized C57BL6 mice were treated with osteogenic doses of IFNγ three times a week for 6 weeks. In distal femur, treated mice showed significantly higher hematopoiesis concomitant with lower levels of fat volume/total volume, adipocyte number, and expression of adipogenic markers when compared with the vehicle-treated mice. Together, these findings demonstrate that, at osteogenic doses, IFNγ also acts as an inhibitor of adipogenesis in vitro and prevents marrow fat infiltration while favors hematopoiesis in ovariectomized mice.

Abstract
Chronic inflammation including autoimmune disease is an important risk factor for the development of osteoporosis. Receptor activator of nuclear factor-κB ligand (RANKL) and macrophage colony-stimulating factor (M-CSF) play a central role in osteoclast differentiation and function, and the molecular pathways by which M-CSF and RANKL induce osteoclast differentiation have been analyzed in detail. Proinflammatory cytokines directly or indirectly regulate osteoclastogenesis and bone resorption providing a link between inflammation and osteoporosis. Tumor necrosis factor-α, interleukin (IL)-1, IL-6, and IL-17 are the most important proinflammatory cytokines triggering inflammatory bone loss. Inhibition of these cytokines has provided potent therapeutic effects in the treatment of diseases such as rheumatoid arthritis. Further investigation is needed to understand the pathophysiology and to develop new strategies to treat inflammatory bone loss. This review summarizes new data on inflammatory bone loss obtained in 2011.
