    BACKGROUNDS: Safe dental treatments that prevent nosocomial and cross-infections are essential for patients and dental workers. However, dental students sometimes pay inadequate attention to infection control, especially in preclinical practice, because of too much focus on technical training, such as the use of equipment, etc. The spread of infections such as SARS-CoV-2, antibiotic-resistant bacteria, and oral bacteria are sometimes lethal for medically compromised patients. Thus, the rapid and inexpensive detection system to detect and measure dental practice-related infection spread during preclinical treatment is highly desired for dental education. This study aimed to establish a method to quantify and visualize infected areas using dental phantoms for safe and effective preclinical dental practices. METHODS: At first, we developed artificial saliva as an in vitro study, including food-derived bacteria and fluorescence dye, which is safe for application to preclinical practice education. In vitro study, the correlation between adenosine triphosphate (ATP) levels and Lactobacillus colony numbers in yogurt was examined using the ATP fluorescent method, with colony counting on yogurt only and a mixture of yogurt and ultraviolet (UV)-sensitive hand lotion. The mixed liquid of yogurt and hand lotion was used as artificial saliva. Second, we used this artificial saliva in preclinical education. The degree of contamination of personal protective equipment and dental chairs in preclinical practice using this artificial saliva was determined using the ATP fluorescent method and measuring the luminescence areas among 10 dentists, 10 dental residents, and 10 fifth-grade dental students. RESULTS: ATP levels and Lactobacillus colony numbers in yogurt were positively correlated with yogurt alone and a mixture of yogurt and UV-sensitive hand lotions (correlation coefficient ≒ 1). Preclinical education using a mixture of artificial saliva successfully quantified and visualized infectious areas and droplets, which revealed significant differences in ATP amounts in personal protective equipment among groups according to years of experience as dental practitioners (p < 0.05). CONCLUSIONS: An education system for infection control constructed using artificial saliva containing Lactobacillus and a UV-sensitive fluorescent hand lotion quantified the infectious areas and degrees. Thus, this method is effective in preclinical practice using dental phantoms.

    AIM: This study aimed to evaluate the effectiveness of oral health assessment tools in facilitating oral health care interventions by dental care providers for acute stroke patients within 48 h of admission, following a reform of the nursing system. METHODS: Data were gathered from a retrospective cohort study conducted at a stroke center, comparing 10 months before and after the implementation of the reformed system, with a 2-month interval. Parameters assessed included stroke type, severity measured using the National Institutes of Health Stroke Scale, stroke history, stroke-related factors, number of teeth, hospitalization cost and duration, occurrence of fever and pneumonia, stroke treatment, days from admission to dental intervention, and intervention frequency. RESULTS: Implementation of the new system significantly reduced the time before dental intervention (P < 0.001), increased the frequency of interventions (P < 0.001), and allowed for the management of more severe cases (P = 0.007). However, there was a slight increase in the occurrence of fevers and the days of fever (P = 0.039 and P = 0.015, respectively). Multiple regression analysis showed that fever days were positively correlated with stroke severity and the number of days from admission to dental intervention (P < 0.001 and P = 0.013, respectively). Even after propensity score matching adjusting for stroke severity, these associations persisted. Additional multiple regression analysis was performed after this, but fever days were positively correlated with stroke severity and sex (P < 0.001 and P = 0.008, respectively), as well as with the presence of other factors affecting the occurrence of fever. CONCLUSIONS: Although the frequency and duration of fevers increased slightly, this approach, incorporating oral health assessment tools, made it possible to provide early dental intervention, particularly for patients with severe strokes.

    BACKGROUND: Plasminogen serves as the precursor to plasmin, an essential element in the fibrinolytic process, and is synthesized primarily in the liver. Plasminogen activation occurs through the action of plasminogen activator, converting it into plasmin. This conversion greatly enhances the fibrinolytic system within tissues and blood vessels, facilitating the dissolution of fibrin clots. Consequently, congenital deficiency of plasminogen results in impaired fibrin degradation. Patients with plasminogen deficiency typically exhibit fibrin deposits in various mucosal sites throughout the body, including the oral cavity, eyes, vagina, and digestive organs. Behcet's disease is a chronic recurrent systemic inflammatory disease with four main symptoms: aphthous ulcers of the oral mucosa, vulvar ulcers, skin symptoms, and eye symptoms, and has been reported worldwide. This disease is highly prevalent around the Silk Road from the Mediterranean to East Asia. We report a case of periodontitis in a patient with these two rare diseases that worsened quickly, leading to alveolar bone destruction. Genetic testing revealed a novel variant characterized by a stop-gain mutation, which may be a previously unidentified etiologic gene associated with decreased plasminogen activity. CASE PRESENTATION: This case report depicts a patient diagnosed with ligneous gingivitis during childhood, originating from plasminogen deficiency and progressing to periodontitis. Genetic testing revealed a suspected association with the PLG c.1468C > T (p.Arg490*) stop-gain mutation. The patient's periodontal condition remained stable with brief intervals of supportive periodontal therapy. However, the emergence of Behçet's disease induced acute systemic inflammation, necessitating hospitalization and treatment with steroids. During hospitalization, the dental approach focused on maintaining oral hygiene and alleviating contact-related pain. The patient's overall health improved with inpatient care and the periodontal tissues deteriorated. CONCLUSIONS: Collaborative efforts between medical and dental professionals are paramount in comprehensively evaluating and treating patients with intricate complications from rare diseases. Furthermore, the PLG c.1468C > T (p.Arg490*) stop-gain mutation could contribute to the association between plasminogen deficiency and related conditions.

    The curriculum at the Department of Pathophysiology in the Periodontal Sciences program at Okayama University includes normative preclinical training (NPT) using phantoms. NPT is given to the whole class of 5 th year students divided in groups of 8 students/instructor. In 2019, an innovative personalized preclinical training (PPT) pilot study was implemented for this group of students whereby two students, each with their own dental unit, were coached by one instructor. The main topics covered were dental ergonomics and endodontics. We aimed to evaluate the effectiveness of PPT in dental ergonomics and endodontics toward increasing the knowledge and future clinical skills of students who had already undergone NPT. A test on endodontics was taken before and after PPT. A questionnaire was completed to assess their perception of improvement regarding the above-mentioned topics. Test scores and questionnaire results both showed that the students' level of knowledge and awareness of future clinical skills was significantly higher after PPT. This pilot study demonstrated that PPT increased the students' knowledge and future clinical skills. As preclinical training forms the foundation for clinical practice, investment in future research regarding this personalized approach is likely to enhance students' understanding and clinical performance.

    Current periodontal treatment focuses on the mechanical removal of the source of infection, such as bacteria and their products, and there is no approach to control the host inflammatory response that leads to tissue destruction. In order to control periodontal inflammation, we have previously reported the optimization of (+)-terrein synthesis methods and the inhibitory effect of (+)-terrein on osteoclast differentiation in vitro. However, the pharmacological effect of (+)-terrein in vivo in the periodontitis model is still unknown. In this study, we investigated the effect of synthetic (+)-terrein on inflammatory bone resorption using a ligature-induced periodontitis mouse model. Synthetic (+)-terrein (30 mg/kg) was administered intraperitoneally twice a week to the mouse periodontitis model. The control group was treated with phosphate buffer. One to two weeks after the induction of periodontitis, the periodontal tissues were harvested for radiological evaluation (micro-CT), histological evaluation (HE staining and TRAP staining), and the evaluation of inflammatory cytokine production in the periodontal tissues and serum (quantitative reverse-transcription PCR, ELISA). The synthetic (+)-terrein-treated group suppressed alveolar bone resorption and the number of osteoclasts in the periodontal tissues compared to the control group (p &lt; 0.05). In addition, synthetic (+)-terrein significantly suppressed both mRNA expression of TNF-α in the periodontal tissues and the serum concentration of TNF-α (both p &lt; 0.05). In conclusion, we have demonstrated that synthetic (+)-terrein abrogates alveolar bone resorption via the suppression of TNF-α production and osteoclast differentiation in vivo. Therefore, we could expect potential clinical effects when using (+)-terrein on inflammatory bone resorption, including periodontitis.

    The major active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25D3), is known for its wide bioactivity in periodontal tissues. Although the exact mechanisms underlying its protective action against periodontitis remain unclear, recent studies have shown that 1,25D3 regulates autophagy. Autophagy is vital for intracellular pathogen invasion control, inflammation regulation, and bone metabolic balance in periodontal tissue homeostasis, and its regulation could be an interesting pathway for future periodontal studies. Since vitamin D deficiency is a worldwide health problem, its role as a potential regulator of autophagy provides new insights into periodontal diseases. Based on this premise, this narrative literature review aimed to investigate the possible connection between 1,25D3 and autophagy in periodontitis. A comprehensive literature search was conducted on PubMed using the following keywords (e.g., vitamin D, autophagy, periodontitis, pathogens, epithelial cells, immunity, inflammation, and bone loss). In this review, the latest studies on the protective action of 1,25D3 against periodontitis and the regulation of autophagy by 1,25D3 are summarized, and the potential role of 1,25D3-activated autophagy in the pathogenesis of periodontitis is analyzed. 1,25D3 can exert a protective effect against periodontitis through different signaling pathways in the pathogenesis of periodontitis, and at least part of this regulatory effect is achieved through the activation of the autophagic response. This review will help clarify the relationship between 1,25D3 and autophagy in the homeostasis of periodontal tissues and provide perspectives for researchers to optimize prevention and treatment strategies in the future.

    The failure of endodontic treatment is directly associated with microbial infection in the root canal or periapical areas. An endodontic sealer that is both bactericidal and biocompatible is essential for the success of root canal treatments. This is one of the vital issues yet to be solved in clinical dental practice. This in vitro study assessed the effectiveness of graphene oxide (GO) composites GO-CaF2 and GO-Ag-CaF2 as endodontic sealer materials. Dentin slices were coated with either the GO-based composites or commonly used root canal sealers (non-eugenol zinc oxide sealer). The coated slices were treated in 0.9% NaCl, phosphate-buffered saline (PBS), and simulated body fluid (SBF) at 37˚C for 24 hours to compare their sealing effect on the dentin surface. In addition, the radiopacity of these composites was examined to assess whether they complied with the requirements of a sealer for good radiographic visualization. Scanning electron microscopy showed the significant sealing capability of the composites as coating materials. Radiographic images confirmed their radiopacity. Mineral deposition indicated their bioactivity, especially of GO-Ag-CaF2, and thus it is potential for regenerative application. They were both previously shown to be bactericidal to oral microbes and cytocompatible with host cells. With such a unique assemblage of critical properties, these GO-based composites show promise as endodontic sealers for protection against reinfection in root canal treatment and enhanced success in endodontic treatment overall.

    Recent studies have shown that periodontitis is associated with rheumatoid arthritis (RA) and periodontal bacteria, such as Aggregatibacter actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg) are involved in the pathogenesis of RA via citrullinated proteins. Smoking has also been shown to be involved in the pathogenesis of RA; however, the extent of this involvement is still poorly understood. In addition, RA and polymyalgia rheumatica (PMR) are sometimes difficult to differentiate; however, the relationship between PMR and the factors from smoking and periodontal bacteria is unclear. The aim of this study was to clarify the relationship between periodontal pathogenic bacterial infections and smoking in patients with RA or PMR. This case-control study included 142 patients with untreated RA or PMR. This study evaluated the serum antibody titers against periodontal pathogenic bacterial antigens and an anti-citrullinated peptide antibody (ACPA). In patients with RA, the relationship between antibody titers and disease activity of RA and response after 3 months of treatment was also investigated. Additionally, the effects of smoking were evaluated. Although there was no significant difference in serum antibody titer against periodontal pathogenic bacteria between the ACPA-positive RA group and the ACPA-negative PMR group, we found an association between the elevated antibody titer against Pg and the degree of ACPA value, especially between negative group and high-value positive group (≥ 100 U/mL). The antibody titers against Aa and Pg did not differ depending on disease activity score 28 (DAS28) at baseline; however, patients with high antibody titers had poor RA therapeutic response as judged by DAS28 after 3 months. We could not find any association between smoking and any of these parameters. Periodontal pathogenic bacteria, especially Pg, are associated with elevated ACPA levels. Our findings suggest that Pg and Aa infections interfere with the therapeutic response of RA.

    BACKGROUND: Periodontal disease is the most common dental disease in dogs. Although the systemic effects of periodontal disease have not been clarified in veterinary science, it is necessary to evaluate the effects of periodontal disease in clinical trials in the future. There have been a few clinical attempts made, however, to assess the severity of periodontal inflammation and its impact on the systemic health of dogs. Meanwhile, in the field of dentistry for humans, the periodontal inflamed surface area (PISA) and periodontal epithelial surface area (PESA) have been used to quantitatively assess the degree of periodontal disease affecting a single tooth as well as the overall extent of periodontitis. Recent studies have also suggested the use of these assessments to examine the relationship between periodontal inflammation and systemic health. RESULTS: The estimation formula for a dog's periodontal pocket surface area (PPSA), an alternative to PISA and PESA in humans, was established using body weight and periodontal pocket depth. Actual values were measured using extracted teeth from various dog breeds and sizes (2.3-25.0 kg of body weight) to obtain universal regression equations for PPSA. Altogether, 625 teeth from 73 dogs of 16 breeds were extracted and subsequently analyzed for morphological information. PPSA was measured in 61 dogs of 10 breeds with periodontal disease using the established estimation formulas, and the correlation between PPSA and preoperative blood chemistry data was analyzed accordingly. A strong correlation was found between PPSA and serum globulin (r = 0.71) while moderate correlations were found for C-reactive protein (r = 0.54) and serum albumin (r = -0.51). CONCLUSIONS: Estimation formulas using body weight and the 6-point probing depth were established for determining PPSA. Direct correlations between PPSA and several blood test results were observed in the study sample. Taken together, these results suggest that PPSA could be useful for evaluating the effects of periodontitis on systemic conditions in dogs.

    Periodontal disease is a chronic inflammatory condition caused by periodontal pathogens in the gingival sulcus. Short-chain fatty acids (SCFAs) produced by causal bacteria are closely related to the onset and progression of periodontal disease and have been reported to proliferate in the periodontal sulcus of patients experiencing this pathology. In such patients, propionic acid (C3), butyric acid (C4), isobutyric acid (IC4), valeric acid (C5), isovaleric acid (IC5), and caproic acid (C6), henceforth referred to as [C3-C6], has been reported to have a detrimental effect, while acetic acid (C2) exhibits no detrimental effect. In this study, we established an inexpensive and simple enzymatic assay that can fractionate and measure these acids. The possibility of applying this technique to determine the severity of periodontal disease by adapting it to specimens collected from humans has been explored. We established an enzyme system using acetate kinase and butyrate kinase capable of measuring SCFAs in two fractions, C2 and [C3-C6]. The gingival crevicular fluid (GCF) and saliva of 10 healthy participants and 10 participants with mild and severe periodontal disease were measured using the established enzymatic method and conventional gas chromatography-mass spectrometry (GC-MS). The quantification of C2 and [C3-C6] in human GCF and saliva was well correlated when using the GC-MS method. Furthermore, both C2 and [C3-C6] in the GCF increased with disease severity. However, while no significant difference was observed between healthy participants and periodontal patients when using saliva, [C3-C6] significantly differed between mild and severe periodontal disease. The enzymatic method was able to measure C2 and [C3-C6] separately as well as using the GC-MS method. Furthermore, the C2 and [C3-C6] fractions of GCF correlated with disease severity, suggesting that this method can be applied clinically. In contrast, the quantification of C2 and [C3-C6] in saliva did not differ significantly between healthy participants and patients with periodontal disease. Future studies should focus on inflammation rather than on tissue destruction.

    Malnutrition causes prolonged inflammation, resulting in delayed wound healing. High mobility group box-1 (HMGB1) is a damage-associated molecular pattern that is present in the nuclei of macrophages and is secreted into the extracellular milieu in response to stimuli. It stimulates the production of interleukin-1β (IL-1β) through the receptors for advanced glycation end products (RAGE), inducing an inflammatory response, which is an essential response to initiate wound healing. We hypothesized that malnutrition may interfere with this cascade, causing abnormal inflammation and ultimately delaying wound healing. We used tooth-extracted mice with malnutrition fed with low-casein diet for two weeks. On days 3 and 7 after tooth extraction, the wound tissue was histologically observed and analyzed for several factors in the inflammation-regeneration lineage, including IL-1β, mesenchymal stem cells, myeloperoxidase activity, HMGB1, macrophage polarization, and adenosine 5-triphosphate (ATP). On day 7, delayed wound healing was observed with the following findings under malnutrition conditions: decreased mRNA expression of genes for regeneration and mesenchymal stem cell (MSC) accumulation, an obvious increase in myeloperoxidase and IL-1β mRNA expression, an increase in HMGB1 levels, and an increase in ATP concentration in tissues with elevated proportion of M2 macrophages. These results suggest that the significantly increased secretion of HMGB1 associated with the upregulated production of ATP and IL-1β secretion via the RAGE pathway may interfere with the resolution of inflammation and wound healing under the state of malnutrition.

    Osteoporosis is a common disease characterized by a systemic impairment of bone mass and microarchitecture that results in fragility fractures. Severe bone loss due to osteoporosis triggers pathological fractures and consequently decreases the daily life activity and quality of life. Therefore, prevention of osteoporosis has become an important issue to be addressed. We have reported that the fungal secondary metabolite (+)-terrein (TER), a natural compound derived from Aspergillus terreus, has shown receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation by suppressing nuclear factor of activated T-cell 1 (NFATc1) expression, a master regulator of osteoclastogenesis. TER has been shown to possess extensive biological and pharmacological benefits; however, its effects on bone metabolism remain unclear. In this study, we investigated the effects of TER on the femoral bone metabolism using a mouse-ovariectomized osteoporosis model (OVX mice) and then on RANKL signal transduction using mouse bone marrow macrophages (mBMMs). In vivo administration of TER significantly improved bone density, bone mass, and trabecular number in OVX mice (p < 0.01). In addition, TER suppressed TRAP and cathepsin-K expression in the tissue sections of OVX mice (p < 0.01). In an in vitro study, TER suppressed RANKL-induced phosphorylation of PKCα/βII, which is involved in the expression of NFATc1 (p < 0.05). The PKC inhibitor, GF109203X, also inhibited RANKL-induced osteoclastogenesis in mBMMs as well as TER. In addition, TER suppressed the expression of osteoclastogenesis-related genes, such as Ocstamp, Dcstamp, Calcr, Atp6v0d2, Oscar, and Itgb3 (p < 0.01). These results provide promising evidence for the potential therapeutic application of TER as a novel treatment compound against osteoporosis.

    This case report highlights the importance of using a dental operating microscope (DOM) and ultrasonic endodontic tips (UETs) to locate all root canals in the lower first premolar. A 53-year-old woman presented to our clinic with pain in the lower right first premolar. After a detailed search using a DOM and UETs, three root canals were found, prepared with rotary HyFlex endodontic files, and obturated using the lateral condensation technique. At the five-year follow-up after treatment, the tooth was completely restored and fulfilling its function, with no signs or symptoms of any post-treatment flare-up.

    <title>Abstract</title>Salivary glands (SGs) are very important for maintaining the physiological functions of the mouth. When SGs regenerate and repair from various damages, including mechanical, radiological, and immune diseases, acinar and granular duct cells originate from intercalated duct cells. However, the recovery is often insufficient because of SGs' limited self-repair function. Furthermore, the precise repair mechanism has been unclear. Here, we focused on CD49f, one of the putative stem cell markers, and characterized CD49f positive cells (CD49f+ cells) isolated from male murine SGs. CD49f+ cells possess self-renewal ability and express epithelial and pluripotent markers. Compared to CD49f negative cells, freshly isolated CD49f+ cells highly expressed inhibin beta A and beta B, which are components of activin that has anti-proliferative effects. Notably, an inhibitor of activin, follistatin was expressed in mechanically-damaged SGs, meanwhile no follistatin was expressed in normal SGs in vivo. Moreover, sub-cultured CD49f+ cells highly expressed both <italic>Follistatin</italic> and a series of proliferative genes, expressions of which were decreased by <italic>Follistatin</italic> siRNA. These findings indicated that the molecular interaction between activin and follistatin may induce CD49f+ cells proliferation in the regeneration and repair of mouse SGs.

    OBJECTIVE: Multiple risk factor syndrome is a clustering of cardiovascular risk factors, such as diabetes, dyslipidemia, hypertension, and obesity associated epidemiologically with insulin resistance. This report describes the clinical course of a patient suffering from severe periodontitis with multiple risk factor syndrome, and discusses the association between periodontal infection and systemic health. METHODS: The patient had a history of type 2 diabetes, dyslipidemia, and hypertension for over 10 years. At baseline, her hemoglobin A1 c was 8.1%. However, she had no diabetic complications except periodontitis. The IgG antibody titers against Porphyromonas gingivalis FDC 381 and SU63 were elevated above the mean of healthy subjects +2 standard deviations. Intensive periodontal treatment, including periodontal surgery, was performed to reduce periodontal infection and bacteremia. Her systemic and periodontal conditions were evaluated longitudinally for 10 years. RESULTS: Following periodontal treatment, antibody titers against Porphyromonas gingivalis and hemoglobin A1c values were significantly improved. The other clinical data and medication for her systemic condition also remained stable during supportive periodontal therapy. However, she developed myocardial infarction, and showed continuous deterioration of hemoglobin A1 c level and periodontitis. CONCLUSION: The long-term clustering of risk factors, such as diabetes, dyslipidemia, hypertension, and periodontitis, are associated with the development of myocardial infarction. Treatment of systemic conditions in combination with comprehensive periodontal treatment is important in management of patients with multiple risk factor syndrome.

    AIM: To develop a detection assay for staphylococcal mecA and spa by using loop-mediated isothermal amplification (LAMP) method. METHODS AND RESULTS: Staphylococcus aureus and other related species were subjected to the detection of mecA and spa by both PCR and LAMP methods. The LAMP successfully amplified the genes under isothermal conditions at 64 degrees C within 60 min, and demonstrated identical results with the conventional PCR methods. The detection limits of the LAMP for mecA and spa, by gel electrophoresis, were 10(2) and 10 cells per tube, respectively. The naked-eye inspections were possible with 10(3) and 10 cells for detection of mecA and spa, respectively. The LAMP method was then applied to sputum and dental plaque samples. The LAMP and PCR demonstrated identical results for the plaque samples, although frequency in detection of mecA and spa by the LAMP was relatively lower for the sputum samples when compared to the PCR methods. CONCLUSION: Application of the LAMP enabled a rapid detection assay for mecA and spa. The assay may be applicable to clinical plaque samples. SIGNIFICANCE AND IMPACT OF THE STUDY: The LAMP offers an alternative detection assay for mecA and spa with a great advantage of the rapidity.

    侵襲性歯周炎(Aggressive periodontitis:AgP)は全身的には健康な若年者に発症し,急速に進行する特殊な歯周炎であるが、その発症病態は不明なままである。本研究では,臓器特異的な作用(臓器トロピズム)が近年注目されている血中の細胞外小胞(EV)とAgPの病態関与の可能性を調べた。
    今年度は、AgP患者6名と健常者3名の初診時血中EVから,AgPで高発現するmiRNAをRNAシーケンスにて調べ,マーカー候補となるそれらのmiRNA mimicをヒト歯肉線維芽細胞と歯周炎モデルマウスに遺伝子導入した。誘導された炎症性サイトカインの発現量をリアルタイムPCR法とELISA法にて測定し,歯槽骨吸収量をマイクロCTにて調べた。
    健常者と比較して,AgP患者で発現量が2倍以上増加したmiRNAを500種類以上同定した。それらのうち5種のmiRNAとmiR-181b-5pを歯肉線維芽細胞に導入すると,IL-6とIL-1βの産生が増加した。とりわけ,miR-181b-5p を歯肉組織に導入すると歯槽骨吸収が進行した。
    すなわち、AgP患者の血中EVには診断マーカー候補となるmiRNAが多く発現しており,miR-181b-5pはIL-6とIL-1β発現を伴う炎症を助長することによってAgPを重症化する可能性が示された。

    Extracellular matrix (ECM) and integrins-mediated microenvironments are important for the recruitment of tissue-resident stem cells. This study investigated the regenerative effects on periodontal tissue by integrin α3-blocking peptide (α325), previously identified as a migration factor of periodontal ligament cells and mesenchymal stem cells. In vivo study using rat horizontal bone defect model and mouse periodontitis model indicated that α325 induced alveolar bone regeneration, equal to or greater than FGF-2. Immunohistochemical analysis indicated that α325 induced mRNA expression of anti-inflammatory cytokines and stem cell marker genes and bone matrix proteins. This study concluded that α325 is a potent peptide-based drug, capable of anti-inflammatory effects and establishing local microenvironments for periodontal regeneration, defined by coordination between growth factors and ECM.

    High mobility group box 1 (HMGB 1) is a DNA binding protein, but it plays as an inflammatory mediator when it is secreted extracellularly due to tissue damage or necrosis. The detailed mechanism of how HMGB1 affects the progress of periodontitis has not been elucidated. As a result of this study, it was revealed that HMGB1 was produced from gingival epithelial cells, macrophage-like cells by inflammatory stimulation. In addition, by administering anti-HMGB 1 antibody to periodontitis model mice, inflammation due to periodontitis is suppressed. As a result, migration of neutrophils, production of IL-1βwere suppressed and the bone resorption by periodontitis was suppressed.

    Periodontal ligament cells (PDLCs) are multipotent cells that can differentiate into osteogenic cells. It is necessary to induce migration of PDLCs for regeneration and homeostasis of periodontal tissue. Cell migration is regulated by local microenvironment, defined by coordination between soluble factors and extracellular matrix (ECM). Integrin-mediated cell adhesion to ECM provides essential signals for cell migration. To determine adhesion molecules responsible for migration of PDLCs, we examined expression profiles of integrin and ECM, and the integrin isoform-specific regulation of migration of PDLCs. The array analysis indicated that mRNA of integrin α2, α3, α4, and α5 were increased in migrating PDLCs. Anti-integrin α3 antibody and blocking peptides significantly increased migration of PDLCs, conversely anti-integrin α5 antibody decreased. Therefore, specific inhibition of integrin α3 may be useful to induce migration of PDLCs during regeneration of periodontal tissue.

    【研究の目的】唾液は,口腔感染制御を含めて口腔内環境を保つ重要な働きを持つ。しかし唾液を分泌する唾液腺は,自己再生能が低く,障害後の機能回復は難しい。我々は,CD49F+細胞がin vitroではINHIBIN βA,INHIBIN βB,FOLLISTATINを発現することを報告している。INHIBINのβ鎖はホモ二量体を構成し,ACTIVIN分子と成る。一方FOLLISTATINは,ACTIVINに特異的に結合し,その受容体への結合を阻害する。本研究は,マウス顎下腺の主排泄導管を結紮後に解除すると顎下腺が再生することを利用し,in vivoにおいて唾液腺組織再生中のCD49F,INHIBIN βA,INHIBIN βB,そしてFOLLISTATINの発現局在の解明を目的とした。
    【研究実施計画および結果】
    マウス顎下腺の片側の排泄導管を血管結紮用クリップで結紮,他方は対照とし,6日後に結紮を解除した。結紮解除1,2,4,8,16日後の顎下腺を摘出し,パラフィン包埋切片作製の後,INHIBIN βA,INHIBIN βB,CD49FそしてFOLLISTATINの局在を免疫組織染色法で検討した。その結果,結紮解除後のどの日数でもINHIBIN βAは染色されず,INHIBIN βBとCD49fは染色された。また,結紮解除後8日目にはFOLLISTATINが染色された。さらに連続切片上で,CD49F,INHIBIN βB,そしてFOLLISTATINが同部位で染色された。以上から,結紮解除後8日目以降の唾液腺組織再生に,CD49F+細胞でのactivin-follistatin相互作用の関与を想定できる。
    以上から本研究を行った結果,マウス顎下腺主排泄導管結紮解除後8日目の導管上皮細胞で,CD49F,INHIBIN βB,FOLLISTATINが発現していることが解明された。

    Periodontal disease, chronic inflammation disease, is caused by infection of periodontal pathogen. It is thought that about 80% of Japanese are affected and it is a major cause of tooth loss. It is still unknown that the difference of progression of periodontal disease for each patient. It is thought that the attachment between gingival epithelial cells and tooth is a physical barrier from infection, and this attachment is important for prevention of periodontal disease. In this study, we hypothesis that growth factors secretes from gingival epithelial cells regulate the attachment between gingival epithelial cells and tooth, and we investigate the mechanism about the regulation.

    We have previously reported that cellular matrix laminin and inflammatory cytokine IL-1αgenes increased during periapical healing phase in a rat periapical periodontitis. In this study, we investigated the effect of these molecules to osteoblast that play a central role in bone formation. Our findings the enhancement of integrin α3 expression by IL-1α and the attachment of osteoblasts to laminin after stimulation with IL-1α suggest an important mechanism for adherence of osteoblasts in periapical healing.

    In periodontal ligament cells (PDL cells), cytoskeletal signaling regulated by Rho-ROCK is critical in the differentiation process, and the expression of osteogenic genes such as BMP-4, Wnt3a, and Wnt5a. Meanwhile over-expression of RhoA or ROCK showed significant low cell proliferation, suggesting that PDL cells differentiation is coordinately regulated by Rho-ROCK induced cytoskeletal molecules, as well as soluble growth factors and extracellular matrix.

    歯髄組織の保存および象牙質の再生を促進するためには,歯髄炎症を分子生物学的アプローチからコントロールすることが有効であると考えられる。本年度は,ラット創傷歯髄から単離した新規遺伝子FIP-2の発現抑制による歯髄炎症のコントロールを目標として,FIP-2が制御する炎症性シグナル分子機構および細胞死への影響を調べた。
    FIP-2に特異的なsiRNAを含む発現ベクターをラット腎臓細胞に遺伝子導入・薬剤選択培養し,FIP-2を発現抑制した細胞株(FIP-2KD)を確立した。FIP-2-KDおよびMockの細胞株をそれぞれ無刺激または過酸化水素にて刺激し,細胞内蛋白の発現変化を抗体アレイで解析し,制御因子の相互関係をIngenuity Signaling Pathways Knowledge Baseを用いてパスウェイ解析を行った。
    Mockに比較してFIP-2-KDでは,一連の細胞増殖因子mitogen activated protein kinase(MAPKS),myelocytosis(MYC),細胞周期制御因子cyclin dependent kinase(CDKS),そしてcell division cycle(CDCS)のシグナルが増強していた。また,細胞死制御因子であるCaspasesのシグナルが減弱していた。一方,過酸化水素で刺激下では,一連の細胞周期制御因子,細胞増殖因子,そして細胞死制御因子の発現が,顕著に抑制されており,DNAの断片化を示すTUNEL陽性細胞はFIP-2-KDにおいて著しく少なかった。
    以上の結果から,FIP-2は,炎症性反応のなかで発現増加し,細胞死を促進させる因子であることが示唆された。FIP-2を局所的に発現抑制することは歯髄の炎症反応の改善に役立つ可能性がある。
