    BACKGROUND: Over 3 years have passed since the outbreak of novel coronavirus disease 2019 (COVID-19), a disease associated with a high risk of severe illness and death among older individuals. This period has brought to light regional and social issues, including issues in overall and regional healthcare, that existed before the epidemic. "COVID-19-related frailty" is defined as secondary damage to health caused by inactivity and disconnection from human interaction owing to prolonged isolation among older individuals. Now in its fourth year, COVID-19 cannot be taken lightly, even though it is now a Category 5 infectious disease. Looking at it from the perspective of the Corona (COVID-19)/post-Corona (COVID-19) era and society, it is necessary to reconstruct regional communities in which active residents can resume their activities, a resilient regional society from multiple perspectives, and a medical and care system that can give the public a sense of security, all of which will lead to the development of local communities. CURRENT SITUATION AND PROBLEMS: Weak healthcare systems in emergencies such as emerging infectious diseases and disasters The COVID-19 pandemic has posed challenges in the management of older individuals in Japan. These challenges are common to those encountered with other emerging infectious diseases and disasters; however, the pandemic has emphasized the vulnerability of older adults. End-of-life care and advance care planning do not function during a contingency The COVID-19 pandemic has had a significant effect on the end-of-life (EOL) care of older adults, with the lack of implementation and dysfunction of advance care planning (ACP) identified as the biggest factors. This has made it difficult for this population to share their values, intentions, and life goals with their families and healthcare providers. Inadequate use of information and communication technology and the latest technologies Disparity in the digital field (digital divide) is more pronounced among older individuals. Consequently, the benefits of new technologies, such as digitalization and robotics, have not fully reached older individuals, leading to social isolation and frailty in this population. Various secondary health outcomes have emerged as a result of the COVID-19 pandemic The influence of misinformation and disinformation following the outbreak of the COVID-19 pandemic has accelerated secondary health outcomes, as excessive isolation in life has become prolonged. The inability of older individuals to screen information is a source of major concern. Furthermore, older adults are generally vulnerable to information technology and often face difficulty in accessing correct information. Lack of human resources in the field of public health The promotion of vaccine development, therapeutic drug development, and measures to prevent serious illnesses among older adults remain major challenges, especially following the COVID-19 pandemic. Information gathering and analysis during normal times are also important issues in the public health, medical care, and nursing care sectors. A shortage of human resources for this purpose has also become evident. CONTENT OF OPINION: The COVID-19 pandemic has led to the compilation of a vision for the future of the aging Japanese society from the viewpoint of individual health as well as from a broader viewpoint of the systems in the medical community, local community, and environment. These views will be reflected in the policies (including cross-ministerial flow) of academic associations such as the Japan Geriatrics Society; the Ministry of Health, Labor and Welfare; the Ministry of Education, Culture, Sports, Science and Technology; the Ministry of Economy, Trade and Industry; the Ministry of Land, Infrastructure, Transport and Tourism; the Cabinet Office; and various professional organizations. Healthcare systems that respond promptly to other emerging infectious diseases, disasters, and contingencies should be reconstructed As an issue that can commonly arise during the COVID-19 pandemic and other emerging infectious diseases, disasters, and other contingencies, a healthcare system designed for the older population, the most vulnerable segment of the population, must be developed. EOL care and ACP that is fully respected even in a contingency should be accelerated ACP should be implemented from an early stage, so that all parties involved can share values, intentions, and life goals with family members and healthcare personnel such that they are reflected in EOL care. This will enable older individuals to live as they desire until EOL. Use of information and communication technology and new technologies should be promoted to actively build new regional communication Disparities in the digital field (digital divide) must be eliminated to create an environment that enables everyone to benefit from digitalization. Furthermore, new regional communication systems, wherein the perspective of mobility support is key, must be created to prevent social isolation. The secondary health outcomes caused by the COVID-19 disaster among older individuals should be prevented through a multifaceted approach Utmost attention must be paid to preventing the occurrence of secondary health outcomes through a multifaceted approach that includes raising awareness regarding health maintenance and providing appropriate information related to health maintenance. Research in the field of public health must be promoted to strengthen human resource development in this area, with a focus on analyzing information on health, medical care, and long-term care from ordinary times Continuous support must be provided even before the occurrence of emergencies to facilitate basic research that will lead to clinical applications. Researchers at universities and research organizations, in particular, must strive to promote these activities. In addition, the government (local and national governments that have data and the national government that supports research and human resource development) must also commit to playing an important role in such research activities.

    To prevent infection in dental implants using photocatalytic activity under visible-light irradiation, the fabrication of Au-added TiO2 layers on Ti substrates and their antibacterial properties were studied. Pure Au and Ti-(60, 40) mol%Au alloy films with thicknesses of 10-47 nm were sputtered onto Ti, followed by thermal oxidation in air at 873 K for 1.8 ks to form TiO2 layers. The antibacterial properties against Escherichia coli, cytotoxicity, and bonding strength to Ti substrates were evaluated. The highest antibacterial activity under visible-light irradiation was obtained when the sputtered film was pure Au and its thickness was 38 nm. Compared with as-polished commercially pure Ti, the number of viable mouse osteoblast-like cells and human gingival fibroblasts on Au-added TiO2 layers increased after placement in the dark but decreased after visible-light irradiation. The best antibacterial property-bonding strength balance was achieved when the Ti-40 mol%Au sputtered film with a thickness of 42 nm was formed on Ti. To the best of our knowledge, this study is the first to report the formation of TiO2 layers with antibacterial activity under visible-light irradiation by combining Au-sputtering and thermal oxidation of Ti.   Mater.

    Hypochlorous acid (HOCl) is an endogenous oxidant and chlorinating agent in mammals that is effective against a broad range of microorganisms. However, the effects of exogenous HOCl on biological processes have not been reported. In this study, the effects of highly purified slightly acidic hypochlorous acid water (HP-HAW) were investigated. After the safety of oral administration of HP-HAW was confirmed, the effects of HP-HAW on glucose homeostasis were assessed in mice. HP-HAW treatment significantly improved blood glucose levels in hyperglycemic condition. Based on the 16S rRNA sequencing, HP-HAW treatment significantly increased the diversity and changed the composition of gut microbiota by decreasing the abundance of genus Romboutsia in mice fed normal chow. In obese mice, HP-HAW administration tended to improve glucose tolerance. HP-HAW also attenuated memory impairments and changes N-methyl-d-aspartate (NMDA) receptor mRNA expression in obese mice. HP-HAW treatment suppressed Il-6 mRNA expression in the hippocampus in type 2 diabetic mice. Overall, these results support HP-HAW as a potential therapeutic agent to improve or prevent glucose tolerance and memory decline via gut microbiota alteration.

    Peyer's patches (PPs), which contain an abundance of B and T cells, play a key role in inducing pivotal immune responses in the intestinal tract. PPs are defined as aggregated lymph follicles, which consist of multiple lymph follicles (LFs) that may interact with each other in a synergistic manner. LFs are thought to be spherical in shape; however, the characteristics of their structure are not fully understood. To elucidate changes in the structure of PPs as individuals grow, we generated serial 2D sections from entire PPs harvested from mice at 2, 4, and 10 weeks of age and performed a 3D analysis using a software, Amira. Although the number of LFs in PPs was not changed throughout the experiment, the volume and surface area of LFs increased significantly, indicating that LFs in PPs develop continuously by recruiting immune cells, even after weaning. In response to the dramatic changes in the intestinal environment after weaning, the development of germinal centers (GCs) in LFs was observed at 4 and 10 weeks (but not 2 weeks) of age. In addition, GCs gradually began to form away from the center of LFs and close to the muscle layer where export lymphatic vessels develop. Importantly, each LF was joined to the adjacent LF; this feature was observed even in preweaning nonactivated PPs. These results suggest that PPs may have a unique organization and structure that enhance immune functions, allowing cells in LFs to have free access to adjacent LFs and egress smoothly from PPs to the periphery upon stimulation after weaning.

    BACKGROUND/PURPOSE: The number of middle-aged and elderly orthodontic patients is increasing due to changes in age composition. It is important to investigate the detailed mechanisms of bone remodeling in orthodontic tooth movement (OTM) in the elderly. However, there are few reports on the mechanism of tooth movement in the elderly. The purpose of the present study was to analyze OTM and osteoclastogenesis in aged mice and to elucidate the mechanism. MATERIALS AND METHODS: It has been reported that tumor necrosis factor (TNF)-α plays an important role in osteoclast formation and OTM. First, 8-week-old and 78-week-old male C57BL/6J mice were subcutaneously injected with TNF-α into the calvaiae, and micro-CT, tartrate-resistant acid phosphatase (TRAP) staining, and real-time PCR were performed to evaluate osteoclast formation and bone resorption. Furthermore, osteoclastogenesis by TNF-α and receptor activator of nuclear factor-kappa B ligand (RANKL) using bone marrow cells was evaluated in vitro. Finally, a nickel-titanium closed-coil spring was attached, mesial movement of the maxillary left first molar was performed, and tooth movement distance and osteoclast formation were evaluated. RESULTS: Compared to 8-week-old mice, 78-week-old mice had decreased TNF-α-induced bone resorption, osteoclastogenesis, and TRAP and cathepsin K expression in the calvariae. In vitro osteoclast formation also decreased in 78-week-old mice. Furthermore, tooth movement distance and osteoclastogenesis were reduced. CONCLUSION: OTM decreased in aged mice, which was shown to be caused by a decrease in osteoclastogenesis. Therefore, it was suggested that it is necessary to keep in mind that tooth movement may be suppressed when treating elderly patients.

    BACKGROUND: In systemic lupus erythematosus (SLE), autoreactive B cells are thought to develop by-passing immune checkpoints and contribute to its pathogenesis. Toll-like receptor (TLR) 7 and 9 signaling have been implicated in their development and differentiation. Although some B cell subpopulations such as T-bet + double negative 2 (DN2) cells have been identified as autoreactive in the past few years, because the upregulated surface markers of those cells are not exclusive to them, it is still challenging to specifically target autoreactive B cells in SLE patients. METHODS: Our preliminary expression analysis revealed that phospholipase D4 (PLD4) is exclusively expressed in plasmacytoid dendritic cells (pDCs) and B cells in peripheral blood mononuclear cells (PBMCs) samples. Monoclonal antibodies against human PLD4 were generated, and flow cytometry analyses were conducted for PBMCs from 23 healthy donors (HDs) and 40 patients with SLE. In vitro cell culture was also performed to study the conditions that induce PLD4 in B cells from HDs. Finally, recombinant antibodies were synthesized from subpopulations of PLD4 + B cells from a patient with SLE, and their antinuclear activity was measured through enzyme-linked immunosorbent assay. RESULTS: pDCs from both groups showed comparable frequency of surface PLD4 expression. PLD4 + B cells accounted for only a few percent of HD B cells, whereas they were significantly expanded in patients with SLE (2.1% ± 0.4% vs. 10.8% ± 1.2%, P < 0.005). A subpopulation within PLD4 + B cells whose cell size was comparable to CD38 + CD43 + plasmablasts was defined as "PLD4 + blasts," and their frequencies were significantly correlated with those of plasmablasts (P < 0.005). PLD4 + blasts phenotypically overlapped with double negative 2 (DN2) cells, and, in line with this, their frequencies were significantly correlated with several clinical markers of SLE. In vitro assay using healthy PBMCs demonstrated that TLR7 or TLR9 stimulation was sufficient to induce PLD4 on the surface of the B cells. Finally, two out of three recombinant antibodies synthesized from PLD4 + blasts showed antinuclear activity. CONCLUSION: PLD4 + B cells, especially "blastic" ones, are likely autoreactive B cells undergoing TLR stimulation. Therefore, PLD4 is a promising target marker in SLE treatment.

    Palladium (Pd) is a widely used metal and extremely important biomaterial for the reconstruction of occlusions during dental restorations. However, metallic biomaterials can cause serious allergic reactions, such as Pd-related oral mucositis seen in dentistry. Metal allergy is categorized as a type IV allergy and we demonstrated that CD8 T cells play an important role in Pd allergy previously. As TCR of CD8 T cells recognizes MHC class I/peptide complex, the antigen specificity to this complex seems to be generated during Pd allergy. However, it remains unknown if Pd affects the MHC class I/peptide complex. In this study, we investigated the behavior of the MHC class I/peptide complex in response to Pd treatment. We found that PdCl2 treatment altered peptide presentation on MHC class I and that co-culture with Pd-treated DC2.4 cells induced activation of Pd-responsive TCR-expressing T cell line. Furthermore, PdCl2 treatment induced temporal MHC class I internalization and inhibition of membrane movement suppressed Pd-induced T cell-mediated antigenicity. These data suggest that Pd-induced MHC class I internalization is critical for generation of antigenicity through a mechanism including differential peptide loading on MHC class I, which results in Pd allergy.

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection induces severe pneumonia and is the cause of a worldwide pandemic. Coronaviruses, including SARS-CoV-2, have RNA proofreading enzymes in their genomes, resulting in fewer gene mutations than other RNA viruses. Nevertheless, variants of SARS-CoV-2 exist and may induce different symptoms; however, the factors and the impacts of these mutations are not well understood. We found that there is a bias to the mutations occurring in SARS-CoV-2 variants, with disproportionate mutation to uracil (U). These point mutations to U are mainly derived from cytosine (C), which is consistent with the substrate specificity of host RNA editing enzymes, APOBECs. We also found the point mutations which are consistent with other RNA editing enzymes, ADARs. For the C-to-U mutations, the context of the upstream uracil and downstream guanine from mutated position was found to be most prevalent. Further, the degree of increase of U in SARS-CoV-2 variants correlates with enhanced production of cytokines, such as TNF-α and IL-6, in cell lines when compared with stimulation by the ssRNA sequence of the isolated virus in Wuhan. Therefore, RNA editing is a factor for mutation bias in SARS-CoV-2 variants, which affects host inflammatory cytokines production.

    Morphogenesis and differentiation of organs is required for subsequent functional maturation. The morphological features of Peyer's patches vary among species. In pigs, they develop extensively in the ileum as ileal Peyer's patches (IPPs). However, the role of IPPs in the porcine immune system remains to be elucidated because of a lack of complete understanding of IPP organogenesis. Results of the present study revealed that development of porcine IPPs is initiated prenatally between embryonic days 76 and 91. The process of IPP organogenesis is concomitant with increased transcriptional patterns of CXCL13 and CCL19. IPPs undergo further development postnatally by forming central, marginal, and subepithelial zones. Importantly, a large number of proliferating B cells and apoptotic cells are found in porcine IPPs postnatally, but not prenatally. The expression level of IgM in proliferating B cells depends on the zone in which distinct B cells are separately localized after birth. Specifically, IgM+ cells are predominantly found in the central zone, whereas IgM-/low cells are abundant in the marginal zone. Importantly, the cellular feature of IPPs differs from that of mesenteric lymph nodes (MLNs) where such distinct zones are not formed both prenatally and postnatally. Our findings suggest that IPPs (not MLNs) in postnatal pigs are involved in complementing functions of the primary lymphoid tissue that promotes the differentiation and maturation of B cells.

    Rutile TiO2 layers were formed on substrates of Ti-(0-10)at%Au alloys by a simple process of air oxidation, and their antibacterial activities were evaluated under visible-light irradiation (λ ≥ 400 nm). Au was introduced into the TiO2 layers on Ti-(1-10)at%Au alloys and existed as both metallic Au nanoparticles and dissolved Au3+ ions. The TiO2 layers that formed on Ti-5at%Au and Ti-10at%Au alloys exhibited visible-light photocatalytic activity, that is, degradation of stearic acid and antibacterial activity against Escherichia coli. These visible-light activities were attributed to the surface plasmon resonance of metallic Au nanoparticles and the decrease in bandgap energy caused by dissolved Au3+ ions. The formation of hydroxyl radicals observed under visible-light irradiation is attributable to antibacterial activity. From a cost perspective, a Ti-5at%Au alloy is more suitable as a substrate for the formation of a TiO2 layer with antibacterial properties than a Ti-10at%Au alloy. © 2019 Wiley Periodicals, Inc.

    BACKGROUND AND PURPOSE: Moyamoya disease (MMD) is a progressive cerebrovascular disease with unknown etiology. Growing evidence suggest its involvement of autoimmune and genetic mechanisms in the pathogenesis of MMD. This study aims to clarify the association between HLA allele and MMD. METHODS: Case-control study: the DNA of 136 MMD patients in Japan was extracted and the genotype of human leukocyte antigen (HLA) from this DNA was determined by super-high-resolution single-molecule sequence-based typing using next-generation sequencing. Next, the frequency of each HLA allele (HLA-A, HLA-B, HLA-C, HLA-DRB1, HLA-DQB1, and HLA-DPB1) was compared with those in the Japanese control database. In addition, haplotype estimation was performed using the expectation maximization algorithm. RESULTS: The frequencies of the HLA-DRB1*04:10 allele (4.77% vs. 1.47% in the control group; P = 1.7 × 10-3; odds ratio [OR] = 3.35) and of the HLA-DRB1*04:10-HLA-DQB1*04:02 haplotype (haplotype frequency 4.41% vs. 1.35% in the control group; P = 2.0 × 10-3; OR = 3.37) significantly increased. The frequency of thyroid diseases, such as Graves' disease and Hashimoto thyroiditis, increased in HLA-DRB1*04:10-positive MMD patients compared with that in HLA-DRB1*04:10-negative MMD patients. CONCLUSIONS: HLA-DRB1*04:10 is a risk allele and HLA-DRB1*04:10-HLA-DQB1*04:02 a risk haplotype for MMD. In addition, HLA-DRB1*04:10 is associated with thyroid disease in MMD patients.

    Macrophages play a key role in inflammation and they are frequently observed in vulnerable atherosclerotic plaque. In the present study, macrophages phagocytosing gold nanorod (AuNR) were observed by optical-resolution (OR) and acoustic-resolution (AR) photoacoustic microscope (PAM). The OR-PAM consisted of diode laser optically focused to 60 micron and planar ultrasonic transducer with the central frequency of 8 MHz placed under the object. AR-PAM consisted of concave ultrasonic transducer with the central frequency of 20 MHz and optical fiber through the center hole of the transducer for laser irradiation. First, PA signal from gold, silver and copper wire were measured in order to determine the best metal substrate for enhancing PA contrast. Gold generated largest PA signal. AuNR with the resonance wavelength of 1064 nm was co-cultured with the macrophages for phagocytosis. PA signal was successfully detected from macrophages with AuNR by both OR-PAM and AR-PAM. PA imaging of the macrophages with AuNR indicates inflammation in the vulnerable plaque and AR-PAM method would be applicable for clinical settings.

    Extracellular matrix (ECM) and its regulatory proteins such as matrix metalloproteinases (MMPs) in skeletal muscles are inextricably linked with regulation of muscle mass and function. ECMs has also been found to be involved in muscle diseases such as muscular dystrophy and muscle mass loss like sarcopenia. We found that batimastat, a broad spectrum MMP inhibitor promotes myosin heavy chain (MHC) expression during myogenic differentiation of C2C12 myoblasts. The expression of myogenin, which is a transcription factor that induces MHC expression, was also enhanced by batimastat. Batimastat promoted MHC expression even under conditions where myogenic differentiation was strongly inhibited, such as differentiation into other cell type (osteoblast) or proliferative cultures. Increased MHC expression was found in other MMP inhibitor possessing similar spectrum to batimastat, but not in specific inhibitors for MMP-3, -9 or -13 in C2C12 myoblasts, suggesting that several MMPs coordinately regulate MHC expression. Interestingly, batimastat-induced enhancement of MHC expression was attenuated in myogenic differentiation of senescent C2C12 myoblasts with elevated senescence-associated β-galactosidase activity. These results indicate that the mechanism regulating myoblast differentiation by MMPs may be altered by cellular senescence. Elucidating the senescence-induced changes in MMP-mediated regulation can contribute to the understanding of the pathogenesis of age-related muscle diseases such as sarcopenia.

    歯科は、生体金属材料を最も使用している診療科である。生体金属材料は、患者のQOLの向上に役立ってきているが、その一方で、金属アレルギーを引き起こすことが報告されており、金属アレルギーの病態解明が求められている。金属アレルギーは、遅延型過敏反応でⅣ型アレルギーに分類されT細胞依存性の免疫疾患とされている。研究代表者は、これまで、歯科金属で広く用いられているパラジウムを対象に金属アレルギー動物モデルを開発して、パラジウムに反応するT細胞の特定、およびT細胞受容体の特定を進めてきた。本研究では、金属アレルギーを引き起こす抗原に着目して、金属アレルギー病原性ペプチドの探索研究を行うことを目的としている。本年度は、病原性ペプチドが提示されると考えられる主要組織適合抗原複合体(MHC)について研究を進めた。マウス抗原提示細胞を用いて培養し、パラジウム溶液を添加した群と添加しない群について、培養をおこなったものの、想定したような細胞増殖が認められなかった。MHCに提示されたペプチドを、質量分析装置で解析するためには、相当量のタンパク質が必要で、そのためには、多数の細胞が必要である。パラジウム溶液添加により、予想に反して細胞の増殖が抑制されたことから、質量分析を行うには工夫が必要であることが判明した。現在、マウス骨髄細胞を分化誘導して用いているが、マウス骨髄細胞数を増やす、あるいは、マウス樹状細胞株を用いるなどして、この問題を解決する予定である。

    Periodontal disease is an infection caused by periodontal pathogenic bacteria and has attracted attention as being caused by the helper T cell Th17, but the detailed mechanism of immune response was unknown. When periodontal pathogenic bacteria were introduced into the intestines of mice at the amount that periodontal disease patients swallow daily, it was found that periodontal pathogenic bacteria were taken up from the Peyer's patches of the intestines and that Th17 cells that respond to periodontal pathogenic bacteria (responsible Th17 cells) were activated in the intestines. Subsequently, we elucidated that the responsible Th17 cells migrate from the gut to the mouth, which is infected with periodontal pathogenic bacteria, causing severe periodontal disease. Meanwhile, in mice without intestinal bacteria, the responsible Th17 cells were not activated and periodontal disease did not occur, indicating that intestinal bacteria were involved in the development of periodontal disease.

    In immunotherapy, immune checkpoint inhibitors have been effective to tumor, but the response rate is about 20%. Therefore, more effective treatment has been desired. This requires a tumor-specific immune response. Using the third-generation T cell receptor repertoire analysis technology developed by the applicants, I aimed to establish a foundation for a new tumor immunotherapy using tumor-specific T cell receptors. Using a soluble form of tumor-specific T cell receptor, binding to target cells was investigated. Tumor-specific T cell receptors could bind to target cell specifically. This method may lead to the development of new therapy using tumor-specific T cell receptor.

    We elucidated the molecular mechanism of the onset of palladium allergy. In vitro culture condition, we found that when antigen-presenting cells were added with a palladium solution, MHC class I expression was reduced and re-expressed on the antigen-presenting cells. It was also found that the antigenic peptide was changed in the process of expression reduction and recovery of MHC class I, and was replaced with a peptide that should not be normally expressed. Furthermore, it was clarified that allergic antigens are expressed and allergic T cells are activated by antigen-peptide substitution with palladium.

    We succeeded in fabricating a Ti surface with both osteogenic and antibacterial properties for application to dental implants. The Au-containing TiO2 layers prepared on the Ti surface by an original process based on Au-sputtering and thermal oxidation showed antibacterial activity against E. coli under visible-light irradiation. The photofunction of the Au-containing TiO2 layers obtained in this study is considered to be an achievement to realize the “self-maintenance function” in which the implant itself plays a role in “healing” by reattaching to bone tissue and also enables “prevention” by patients themselves. These results, together with the excellent adhesion between the TiO2 layers and the Ti substrates, are expected to be applied not only to dental implants but also to the prevention of contact infection of the new coronavirus (SARS-CoV-2).

    In this study, we investigated the molecular mechanism by which the antigen peptide-MHC complex modified by haptens as “neo-self”. To explore the mechanisms, we analyzed T cell receptors that react with haptens such as metal. We identified the metal allergy-specific T cell receptors in a mouse model of metal allergy using palladium (Pd). Furthermore, by in vitro cell culture system, we found that the antigen peptide-MHC complex was changed by Pd solution and the expression of MHC was transiently reduced. In other words, we found that the behavior of the antigen peptide-MHC complex induces changes in the repertoire of T cell receptors. Therefore, our findings suggest that the behavior of antigen peptide-MHC complex may be induce the neo-self.

    Abatacept was administered to 15 patients with rheumatoid arthritis who did not lose their activity despite existing treatment. Before treatment, peripheral blood was collected from patients and lymphocytes were separated from peripheral blood. Repertoire analysis of B cell receptor and T cell receptor was performed on the obtained lymphocytes. Abatacept was treated for more than three months in these patients. After treatment, a second repertoire analysis of B cells and T cells was performed and compared with the repertoire before treatment. Abatacept treatment was effective in 70% of patients. Specific T cell repertoire decreased before and after treatment in lymphocytes obtained from patients who responded to these treatments

    Although immune checkpoint inhibitors have been effective against intractable tumors, we hope more effective treatments. Therefore, we performed a study to detect tumor-specific T cell receptors. When mouse peripheral tissues around tumors and lymphoid tissues were collected using a tumor-bearing mouse model, T cell accumulation was observed around the tumors. In addition, it was possible to detect T cell receptors that are considered to be tumor-specific in lymphoid tissues around the tumor. Furthermore, we were able to establish a comprehensive analysis method for T cell receptors.

    Metal allergy is considered to be delayed-type of allergy by T-cell dependent diseases, but its immune mechanism is not well understood. In this study, we performed to clarify the characteristics of T cells involved in the onset of metal allergy using the our technology. We found that non-biased gene amplification plays a very important role in T cell receptor analysis. Thus, in T cell receptor analysis, it is necessary to use a non-biased gene amplification method, such as a single chain adapter ligation PCR by our technology.

    Metal is used as a component of biomaterials in dental care, because metal has stiffness, elasticity, and ductility. In dental care, the metal is frequently used as a part of denture, an implant and restoration. However, the molecular mechanisms underlying metal inflammation and metal allergy have not been understood. In this study, we examined the molecular mechanism of development for metal allergy and inflammation by focusing NK cells and NK receptors. We found that NKG2D, a NK activating receptor, is expressed on CD8+T cells are involved in metal allergy.

    To develop effective diagnostic methods and treatment of oral cancer, NKG2D-ligand expression on human oral cancer cell lines was analysed by a flowcytometer. As a result, the only weak expression of NKG2D-ligand was determined on two tumor cell lines. In addition, the expression of NKG2D-ligand was analysed by immunohistochemical methods on normal cells, the epithelial dysplasia cells and squamous carcinoma cells, no expression was observed on all type cells. On the other hand, the high expression of PD-1 ligands, which are immune control receptors, was determined on two tumor cell lines by a flowcytometric analysis. In the future, we will check the PD-1 ligand expression in the past of pathological tissue specimens. These results suggested that PD-1 ligands, but not NKG2D ligands, will be new marker for diagnosis of oral cancer.

    Ceramic coating layers of amorphous calcium phosphate (ACP) and TiO2 were prepared on Ti, and their antibacterial activities were evaluated. Ag-containing ACP layers fabricated by RF magnetron sputtering exhibited antibacterial activity through the continuous release of Ag ions, caused by the resorbability of ACP. TiO2 layers fabricated by thermal oxidation processes showed photodegradation of organic compounds and antibacterial activity under both UV- and visible-light irradiation. The introduction of Au into TiO2 layers from Ti-Au alloy substrates contributed to the expression of visible-light response. The optimized fabrication processes provided the coating films with both the bone forming ability and antibacterial activity.

    Although amorphous silica particles are used in a wide variety of products such as pharmaceuticals and foods, the immunotoxicity of these particles is not fully understood. In this study, we addressed the relationship between the size of amorphous silica and the inflammatory activity. Of note, 30 nm-1000 nm diameter silica particles induced macrophage lysosomal destabilization, cell death, and IL-1β secretion at markedly higher levels than did 3000 nm-10000 nm silica particles. Consistent with in vitro results, intra-tracheal administration of 30 nm silica particles into mice caused more severe lung inflammation than that of 3000 nm silica particles. Taken together, these results suggest that silica particle size impacts immune responses, with submicron amorphous silica particles inducing higher inflammatory responses than silica particles over 1000 nm in size.

    Dental metal has increased the patient's QOL as a repair material. However, safer alternative materials are desired, because there is a possibility that several oral disease may be caused by dental metal. The "ultra-high purity iron (UHP-Fe)" that is the next-generation material unparalleled in the world has been generated in the Institute for Materials Research at Tohoku University. We also developed the novel safety test for evaluating biomaterials using experimental animal model. In this study, our purpose is to examine whether UHP-Fe is valuable for safer biomaterials in the clinical application using the safety test in vivo. We injected the wire of UHP-Fe into the mice subcutaneously, Five days later we obtained the surrounding tissue embedded in the metal wire. To investigate the elution of metal ions in the in vivo, we were dissolved the surrounding tissue and the solution was analyzed by mass spectrum analysis metal ions quantitative analysis technique (ICP-MS method). In addition, the removed wires were detected the corrosion of metal surfaces by scanning electron microscopy (SEM method). There is almost no corrosion of the surface ultra-high purity iron and inflammation of the subcutaneous tissue was not observed. Therefore, ultra-high purity iron is a safe biological material, suggesting that it will become a new medical biomaterial in the future.

    Autoimmune disease is considered to be caused by genetic factors, environmental factors, and the time factor. However, the diagnostic methods including environmental factors and a time factor have not been established. NK cells are known as a group of cells of the innate immune system. NK cell has been examined cell surface molecules and receptors in the view of the elimination of tumor and infection defense. Therefore, until now it has been unknown whether NK receptors and NK cells are involved in autoimmune disease. In this study, we performed experiments on the basis of the original idea by which NK receptors and NK cells are involved in autoimmune diseases. Our purpose was to explore new biomarkers of autoimmune diseases, such as systemic lupus erythematosus (SLE) and type I diabetes for a diagnostic index.In this study we found that NKG2D ligands that do not express almost normal tissues isabnormally expressed in autoimmune disease model mice, and autoreactive T cells had abnormally express NKG2D. Therefore, these results suggest that NKG2D ligand isavailable as a new biomarker in type I diabetes.

    In recent years, a lot of medical biomaterials have been developed and have been widely used. Metal is used as a component of biomaterials in dental treatment, because metal is easy to process and metal has stiffness, elasticity, and ductility. In dentistry, the metal is frequently used as a part of denture, an implant and crown restoration. Also, it is utilized as vascular stents and artificial joint material in medical area. However, since oral disease, inflammation and allergic dermatitis are caused by metal, the risk has been pointed out previously. Recently, patients of allergic dermatitis or inflammation, which are caused by metal are increased, because the frequency of use of metal material by improving medical and dental technology is increased, and people to put the ornaments such as necklaces and earrings are increased. However, the pathogenesis of the disease induced by the metal is not well understood.In this study, we addressed to develop new diagnostic methods for delayed-type hypersensitivity and inflammation induced by metal using the experimental animal model and we examined the molecular mechanism of development for metal allergy and inflammation.In lymphocyte stimulation test using the patient's peripheral blood for diagnostic metal allergy, we found that the sensitivity is enhanced by inhibition of CTLA-4. In this method, we may develop new method of lymphocyte stimulation test for diagnostic metal allergy. In a mouse model metal allergy, we were able to develop a new animal model ofmetal allergy which is closer to the human pathology.

    Autoimmune diseases are caused by abnormal immune responses in self-tissues. Co-stimulatory molecules play important roles in immune responses. We focused the signaling mechanisms of co-stimulatory molecules and their ligands to explore development of autoimmune diseases. Type I diabetes is an autoimmune disease in which insulin-producing beta cells in pancreatic islets are destroyed by auto-reactive T cells. We showed that autoreactive T cells infiltrating the pancreas in diabetic NOD mice express NKG2D and NKG2D ligands are present in the pre-diabetic pancreas islets. Treatment with anti-NKG2D monoclonal antibody during the pre-diabetic stage completely prevented disease by impairing expansion of autoreactive T cells and blocking their effector functions. However, the molecular mechanisms by which RAE-1, one of NKG2D ligands are expressed in the pancreas in the development diabetes are unknown. We found that RAE-1 expression is regulated by transcriptional factors and that RAE-1 alpha is a major NKG2D ligand in NOD. In addition, transcriptional activator (s) derived from NOD may regulate RAE-1 alpha expression.
