    ABSTRACT

    Chronic kidney disease (CKD)-associated dysbiosis is well described after diagnosis, but whether microbial changes precede clinical recognition is unclear. We integrated insurance claims, fecal and oral 16S rRNA profiles, and clinical laboratory data from companion dogs. Among 140,025 dogs, lower gut microbial diversity was associated with incident CKD after adjustment for age, sex and body size. Prediagnostic samples showed reduced evenness-related diversity, modest community shifts and seven differentially abundant genera. A five-genus score was elevated more than two years before diagnosis, although it was derived and evaluated in the same cohort and was not intended as a predictive model. In a laboratory subset, microbial changes preceded the largest increases in blood urea nitrogen and creatinine. Paired oral-gut samples showed limited exploratory associations between periodontal-associated taxa and the gut score. These findings identify microbial features associated with future claims-defined canine CKD and support independent validation and mechanistic investigation.

    Purpose

    To evaluate familial clustering of Sjögren’s disease (SjD) with other autoimmune diseases and to characterize shared genetic architecture using an integrative genomic approach.

    Methods

    Meta-analysis identified studies assessing autoimmune disease incidence in probands and first-degree relatives (FDRs), and pooled relative risks (RRs) were calculated. Publicly available genome-wide association study (GWAS) summary statistics were analyzed within a hierarchical genetic architecture framework integrating genome-wide polygenic correlation (LDSC), locus-level overlap (Jaccard index), union-based susceptibility mapping, and SNP-level pleiotropy detection.

    Results

    Eighteen studies evaluated familial aggregation of SjD and other autoimmune diseases, of which nine were included in the pooled analysis. The RR of SjD was 10.54 when both proband and FDR were affected. Among discordant autoimmune probands, systemic lupus erythematosus (SLE) showed the highest RR for SjD (4.49), followed by systemic sclerosis (2.65). Genome-wide analyses demonstrated substantial polygenic sharing between SjD and systemic autoimmune diseases, positioning SjD as a bridging disorder. However, locus-level overlap was largely driven by the HLA region; after HLA exclusion, shared loci markedly decreased and were restricted to a limited number of immune regulatory hubs. SNP-level pleiotropy analyses similarly indicated predominantly HLA-dependent sharing with fewer non-HLA signals.

    Conclusion

    SjD shows strong familial aggregation and shared genetic susceptibility with multiple autoimmune diseases. These findings support a hierarchical model in which broad HLA-driven polygenic sharing coexists with selective non-HLA convergence.

    Strengths and limitations of this study

    This study integrates systematic familial meta-analysis with GWAS data to characterize shared autoimmune genetic architecture. However, inference regarding shared causal variants remains limited by reliance on summary statistics and locus-based resolution.

    PURPOSE: Genetic causes of surfactant dysfunction are associated with childhood interstitial lung disease (chILD). Lysosome-associated membrane glycoprotein 3 (LAMP3) is highly expressed within lamellar bodies of alveolar epithelial type II cells, and variants in LAMP3 have recently been suggested as a novel cause of chILD. This study describes the phenotypes of participants with biallelic variants in LAMP3 and presents functional studies evaluating the role of specific LAMP3 variants. METHODS: Phenotypic data was collected through chart review and clinical evaluation. In vitro effects of LAMP3 variants were evaluated through immunohistochemistry, WB, and flow cytometry. RESULTS: Thirteen participants were identified with biallelic variants in LAMP3. They presented with variable phenotypes ranging from neonatal respiratory distress to asymptomatic in adulthood. All symptomatic participants demonstrated ground glass opacities early in life and lung fibrosis later in life. For one participant, BAL analysis showed abnormal surfactant protein composition and lung biopsy revealed irregular LB. In vitro studies in lung epithelial cells with induced expression of specific LAMP3 variants demonstrated reduced protein expression and abnormal glycosylation. CONCLUSIONS: Biallelic LAMP3 variants are associated with an interstitial lung disease phenotype with variable expressivity. Evaluation for LAMP3 variants should be considered in individuals with unexplained interstitial lung disease.

    Some forms of Sjögren's syndrome (SS) follow a clinical course accompanied by systemic symptoms caused by lymphocyte infiltration and proliferation in the liver, kidneys, and other organs. To better understand the clinical outcomes of SS, here we used minor salivary gland tissues from patients and examine their molecular, biological, and pathological characteristics. A retrospective study was performed, combining clinical data and formalin-fixed paraffin-embedded (FFPE) samples from female patients over 60 years of age who underwent biopsies at Okayama University Hospital. We employed direct digital RNA counting with nCounter® and multiplex immunofluorescence analysis with a PhenoCycler™ on the labial gland biopsies. We compared FFPE samples from SS patients who presented with other connective tissue diseases (secondary SS) with those from stable SS patients with symptoms restricted to the exocrine glands (primary SS). Secondary SS tissues showed enhanced epithelial damage and lymphocytic infiltration accompanied by elevated expression of autophagy marker genes in the immune cells of the labial glands. The close intercellular distance between helper T cells and B cells positive for autophagy-associated molecules suggests accelerated autophagy in these lymphocytes and potential B cell activation by helper T cells. These findings indicate that examination of FFPE samples from labial gland biopsies can be an effective tool for evaluating molecular histological differences between secondary and primary SS through multiplexed analysis of gene expression and tissue imaging.

    The mouse Harderian gland (HG) is a secretory gland that covers the posterior portion of the eyeball, opening at the base of the nictitating membrane. The HG serves to protect the eye surface from infection with its secretions. Mice open their eyelids at about 2 weeks of age, and the development of the HG primordium mechanically opens the eye by pushing the eyeball from its rear. Therefore, when HG formation is disturbed, the eye exhibits enophthalmos (the slit-eye phenotype), and a line of Fgf10+/- heterozygous loss-of-function mice exhibits slit-eye due to the HG atrophy. However, it has not been clarified how and when HGs degenerate and atrophy in Fgf10+/- mice. In this study, we observed the HGs in embryonic (E13.5 to E19), postnatal (P0.5 to P18) and 74-week-old Fgf10+/- mice. We found that more than half of the Fgf10+/- mice had markedly degenerated HGs, often unilaterally. The degenerated HG tissue had a melanized appearance and was replaced by connective tissue, which was observed by P10. The development of HGs was delayed or disrupted in the similar proportion of Fgf10+/- embryos, as revealed via histology and the loss of HG-marker expression. In situ hybridization showed Fgf10 expression was observed in the Harderian mesenchyme in wild-type as well as in the HG-lacking heterozygote at E19. These results show that the Fgf10 haploinsufficiency causes delayed or defective HG development, often unilaterally from the unexpectedly early neonatal period.

    The vertebrate body comprises four distinct cell populations: cells derived from (1) ectoderm, (2) mesoderm, (3) endoderm, and (4) neural crest cells, often referred to as the fourth germ layer. Neural crest cells arise when the neural plate edges fuse to form a neural tube, which eventually develops into the brain and spinal cord. To date, the embryonic origin of exocrine glands located in the head and neck remains under debate. In this study, transgenic TRiCK mice were used to investigate the germinal origin of the salivary and lacrimal glands. TRiCK mice express fluorescent proteins under the regulatory control of Sox1, T/Brachyury, and Sox17 gene expressions. These genes are representative marker genes for neuroectoderm (Sox1), mesoderm (T), and endoderm (Sox17). Using this approach, the cellular lineages of the salivary and lacrimal glands were examined. We demonstrate that the salivary and lacrimal glands contain cells derived from all three germ layers. Notably, a subset of Sox1-driven fluorescent cells differentiated into epithelial cells, implying their neural crest origin. Also, these Sox1-driven fluorescent cells expressed high levels of stem cell markers. These cells were particularly pronounced in duct ligation and wound damage models, suggesting the involvement of neural crest-derived epithelial cells in regenerative processes following tissue injury. This study provides compelling evidence clarifying the germinal origin of exocrine glands and the contribution of neural crest-derived cells within the glandular epithelium to the regenerative response following tissue damage.

    BACKGROUND: Oral care with gel is a common method for preventing aspiration in high-risk patients. An oral care gel is used to clean and moisturize the oral cavity. However, the effects of gel care on the oral bacteria remain unclear. In this pilot study, we described a matching transformation system (MA-T) for elderly high-risk patients. MA-T is an on-demand aqueous chlorine dioxide solution that provides excellent safety and has various antimicrobial activities, even in the presence of abundant organic compounds. This study investigated the effects of MA-T gel in patients requiring nursing care. MATERIALS AND METHODS: Patients who were hospitalized for nursing care were included in this study. No drugs and foods were administered orally. Oral bacteria and intraoral humidity were examined by daily care using MA-T gel. Moreover, oral membranous substances were analyzed and material from the oral cavity was cultured on selective media for identifying opportunistic organisms. RESULTS: Membranous substances were present in the oral cavities of all patients. The number of bacteria decreased, and oral moisture improved, after treatment with MA-T gel. Moreover, oral humidity was also controlled with the continued use of MA-T gel. MA-T gels should be used not only for professional care but also on a daily basis for better oral care. Furthermore, the results of bacterial cultures showed that MA-T controls the propagation of opportunistic bacterial infections. CONCLUSION: Membranous substances may be observed in the oral cavity of individuals requiring nursing care for tube feeding. The results of this pilot study suggest that MA-T, a novel disinfectant, can be used for oral care in the elderly to reduce the risk of aspiration-pneumonia.

    OBJECTIVES: To determine the general condition of elderly xerostomia patients, we collected their background and medication data in order to potentially treat their xerostomia. It is critical to identify the drugs causing xerostomia in elderly patients. A total of 521 patients who were examined at the Xerostomia Clinic of Osaka University Dental Hospital were included in the study. We obtained patients' data on age, sex, number of primary illnesses, Saxon test scores, oral moisture test, subjective symptoms, and drug types from their clinical records. RESULTS: The mean age of the patients was 65.2 ± 13.3 years. Although all patients exhibited xerostomia symptoms, there were a lot of patients without hyposalivation. With respect to medication, each elderly xerostomia patient took an average of 6.8 ± 4.4 medicines. A total of 26.1% of patients in their 70 s took more than ten number of drugs. In addition, the number of frequently used medication medicine was different between elderly and young patients. Most of the medicines had xerostomia as a side effect in medical package inserts. Moreover, the quantity of salivation significantly decreased in patients who took more than seven drugs in comparison with the patients who did not take medicine. CONCLUSIONS: As patients age, the number of medications they take tends to increase, subsequently increasing their risk of xerostomia. For the health of the patients, it is critical that an accurate diagnosis is made. CLINICAL RELEVANCE: To establish therapeutic strategies for treatment of xerostomia, this study provides new and important information that will help in the development of xerostomia medical treatment.

    BACKGROUND: Dry mouth is associated with salivary gland hypofunction, which may result from several conditions such as Sjögren's syndrome (SS), head and neck cancers, and side effects of medications. The Saxon test is a useful diagnostic method for hyposalivation in clinical settings. However, previous reports indicate that the test has mostly been used for patients with SS. OBJECTIVE(S): In the present study, we focused on patients with dry mouth who were not diagnosed with SS (patients without SS). METHODS: For patients without SS (n = 302), we examined the factors affecting Saxon test scores using multiple regression analysis. Additionally, we performed a correlation analysis comparing the Saxon test with other diagnostic methods. RESULTS: In 57.6% patients, the Saxon test score was more than 2.00 g/2 min, which is considered negative for hyposalivation. Multiple regression analysis revealed that the age and sex of patients significantly influenced test scores. The mean Saxon test score was less than 2.00 g/2 min in older patients and women. Moreover, the test showed a significant correlation with other methods used to measure salivary flow. CONCLUSION: The Saxon test is useful not only for patients with SS but also for patients without SS.

    The transcription factor p63, a component of the p53 family, has important functions in development, homeostasis, and regeneration of epithelial tissues. However, the role of p63 in the regeneration of exocrine glands, including the salivary glands (SGs), has not been fully investigated. We investigated p63 expression in SG regeneration induced by duct ligation and irradiation. The expression of ΔNp63, a p63 isoform, increased and was colocalized with keratin 5 positive cells were myoepithelial cells. Furthermore, ΔNp63 expression was regulated by FGF7 stimulation via p38 MAPK phosphorylation and affected SG morphogenesis. These results suggest that ΔNp63 is essential for SG regeneration and may be a new target for regenerative treatment.

    BACKGROUND: Most animals and organs have regenerative capabilities. Whether regeneration is a developmental process or a distinct phenomenon that is independent of development is debatable. METHOD: We examined the differences between developing and regenerating salivary glands using duct-ligation models. We performed morphological analyses comparing submandibular gland regeneration and development. To reveal the proliferation processes that occur during salivary gland regeneration and development, we counted the number of Ki67-positive cells over time. In addition, we examined the expression of the following markers: aquaporin 5, smooth muscle actin, cytokeratin 7, and tubulin beta 3. RESULT: The proliferation patterns seen during regeneration differed from those observed during development. Different salivary gland marker expression patterns were seen during development and regeneration. CONCLUSION: This study showed that regenerating salivary glands do not follow the same growth process as developing salivary glands.

    Hypofunction of the salivary gland causes several life-disrupting side effects such as dental caries, oral candidiasis, loss of taste, and swallowing disorders. No satisfactory therapy has been established to treat salivary hypofunction. Pilocarpine represents a potential treatment for dry mouth due to Sjögren's syndrome (SS). Although subjective improvement was consistently observed with pilocarpine therapy, the mechanism was unclear. In this study, we investigated the mechanism of recovery in salivation following treatment with pilocarpine. We first examined the effectiveness of pilocarpine in SS patients as quantified by the Saxon test and the visual analogue scale average. We found that salivation ability and subjective symptoms improved by continuous administration of pilocarpine. These results demonstrated that long-term medication for dry mouth patients was more effective. However, as the mechanism remained unclear, molecular biological mechanisms were analyzed based on the effects of continuous administration of pilocarpine using model mice. In the molecular biological analysis, continuous administration of pilocarpine was effective in both ICR and SS model mice. Gene and protein expression of muscarinic acetylcholine receptor 3 (M3R) increased in salivary glands following continuous administration of pilocarpine compared with single administration. Therefore, continuous administration of pilocarpine effectively induced M3R expression, thereby activating salivation.

    Salivary secretion displays day-night variations that are controlled by the circadian clock. The central clock in the suprachiasmatic nucleus (SCN) regulates daily physiological rhythms by prompting peripheral oscillators to adjust to changing environments. Aquaporin 5 (Aqp5) is known to play a key role in salivary secretion, but the association between Aqp5 and the circadian rhythm is poorly understood. The aim of our study was to evaluate whether Aqp5 expression in submandibular glands (SMGs) is driven by the central clock in the SCN or by autonomous oscillations. We observed circadian oscillations in the activity of period circadian protein homolog 2 and luciferase fusion protein (PER2::LUC) in cultured SMGs with periodicity depending on core clock genes. A daily rhythm was detected in the expression profiles of Aqp5 in SMGs in vivo. In cultured SMGs ex vivo, clock genes showed distinct circadian rhythms, whereas Aqp5 expression did not. These data indicate that daily Aqp5 expression in the mouse SMG is driven by the central clock in the SCN.

    STUDY OBJECTIVES: The aim of this study was to investigate the predictors of dental changes associated with long-term treatment with oral appliances (OAs) in patients with obstructive sleep apnea (OSA). METHODS: This was a retrospective study to investigate Japanese patients with OSA receiving long-term treatment with OAs. Comparisons of cephalometric analysis were carried out between the initial and follow-up assessments of dental and skeletal changes. Based on dental changes, predictors that may cause side effects were investigated. RESULTS: A total of 64 patients (average age at start of treatment: 57.7 ± 14.2 years, 44 males) were included in this study. The average duration of treatment was 4.3 ± 2.1 years. Over the total treatment period, there was a significant reduction in overjet (OJ) (1.5 ± 1.3 mm) and overbite (0.90 ± 1.5 mm), and an increase in the lower incisor line to the mandibular plane (3.1 ± 5.4°). A larger reduction in OJ of ≥ 1 mm was associated with treatment duration, use frequency, and mandibular advancement of the OAs. In addition to these predictive factors, the number of teeth was correlated with the amount of OJ reduction. CONCLUSIONS: For long-term treatment with OAs, the risk of dental side effects should be considered, such as a reduction in OJ. A small number of maxillary teeth, as well as the factors associated with OAs, including treatment duration, use frequency, and mandibular advancement of the OAs, was correlated with an increased rate of OJ reduction. COMMENTARY: A commentary on this article appears in this issue on page 7.

    Many organs, including salivary glands, lung, and kidney, are formed by epithelial branching during embryonic development. Branching morphogenesis occurs via either local outgrowths or the formation of clefts that subdivide epithelia into buds. This process is promoted by various factors, but the mechanism of branching morphogenesis is not fully understood. Here we have defined melatonin as a potential negative regulator or "brake" of branching morphogenesis, shown that the levels of it and its receptors decline when branching morphogenesis begins, and identified the process that it regulates. Melatonin has various physiological functions, including circadian rhythm regulation, free-radical scavenging, and gonadal development. Furthermore, melatonin is present in saliva and may have an important physiological role in the oral cavity. In this study, we found that the melatonin receptor is highly expressed on the acinar epithelium of the embryonic submandibular gland. We also found that exogenous melatonin reduces salivary gland size and inhibits branching morphogenesis. We suggest that this inhibition does not depend on changes in either proliferation or apoptosis, but rather relates to changes in epithelial cell adhesion and morphology. In summary, we have demonstrated a novel function of melatonin in organ formation during embryonic development.

    This report describes our initial attempt to regenerate salivary glands using induced pluripotent stem (iPS) cells in vivo and in vitro. Glandular tissues that were similar to the adult submandibular glands (SMGs) and sublingual glands could be partially produced by the transplantation of iPS cells into mouse salivary glands. However, the tumorigenicity of iPS cells has not been resolved yet. It is well known that stem cells affect their microenvironment, known as a stem cell niche. We focused on the niche and the interaction between iPS cells and salivary gland cells in our study on salivary gland regeneration. Coculture of embryonic SMG cells and iPS cells have better-developed epithelial structures and fewer undifferentiated specific markers than monoculture of embryonic SMG cells in vitro. These results suggest that iPS cells have a potential ability to accelerate differentiation for salivary gland development and regeneration.

    唾液腺の発生は口腔粘膜上皮が肥厚し問葉組織へ索状に侵入することによって始まり、分枝形成、導管形成、終末部での細胞分化を経て形成される。唾液腺の発達過程におけるシグナルや器官形成過程は数多く報告されているものの、発生機序は未知の点が多い。一概に唾液腺といっても耳下腺、顎下腺、舌下腺、小唾液腺など異なった働きを持ち、構造も細胞レベルから全く違う性質を持つことからそれぞれが異なった遺伝子に基づいた発生機序をとると考えられる。そこで申請者は本研究で、唾液腺の本当の起源を明らかにするという学術的「問い」に挑戦したいと考えている。そこで本研究では各唾液腺の違いにフォーカスを当て、唾液腺発生の過程を解明する。さらに粘液腺と漿液腺の分化スイッチをオンする遺伝子を見出すことで唾液腺組織を誘導まで展開する。まず本年度は唾液腺が発生中の胚のどの細胞に由来するかを探索した。TRiCK(TRiple Coloured germ layer Knock-in)マウスはSox1、Brachyury, Sox17にそれぞれ異なる蛍光がついたマウスで、慶応大学で作成された(Serizawa et al, Development, 2019)。TRiCKマウスを継時的にサンプリングし、初期発生における細胞系譜を解析を行っている。連携研究者である慶応大学の岡野先生から譲渡をうけ、成体唾液腺におけるTRiCKマウスの組織解析を進めているところである。胎生期も含め順次サンプル数を増やしてより詳細な解析を行っている。
    さらに唾液腺は分泌される唾液や組織学的な違いから粘液腺と漿液腺に分類される。胎生期マウスが粘液腺と漿液腺に分化するタイミングに必須となる遺伝子を網羅的な解析を行っている。

    本国際共同研究の目的は、唾液腺細胞の増殖と発生機構に注目して、放射線による組織の障害を軽減できる薬剤、放射線障害から組織再生を誘導できる薬剤を探索し、臨床応用を目指すことである。細胞増殖活性を高め臓器形成を誘導する薬剤を網羅的に探索することと、放射線照射を用いて投与薬剤の障害抑制効果を判定する予定である。将来的には、唾液腺で得られた知見を活用し、肺・腎臓・乳腺・涙腺などの他臓器の再生医療に発展させることを目標としている。臓器の損傷・修復機構を解明するために、マウス唾液腺の損傷・修復モデルを作成した。唾液腺損傷後の組織を解析し、修復過程を詳細に観察し、指標となる組織を見出そうと探索してきた。
    【損傷・修復モデルの観察】放射線照射後の成体マウス唾液腺の変化を観察する。照射距離、照射範囲、照射量を検討し、継時的に組織を採取し、損傷後に修復する過程を組織学的に観察している。
    【組織により異なる損傷程度の検討】唾液腺組織は大きく上皮組織と間葉組織で構成されている。さらに上皮自体も細分化され、腺房、導管だけでなく、周囲は筋上皮、神経などから形成されている。損傷後、周囲環境と相互作用しながら、組織が修復される。再生過程における上皮細胞の動態を調査している。
    【細胞増殖・臓器形成を誘導する薬剤のスクリーニング】FDA承認済み化合物や薬理活性が判明した化合物、米国で臨床試験まで到達した化合物等を用いて薬剤のスクリーニング検査を行う。成体マウス唾液腺細胞と培養細胞株、胎生13日目の唾液腺を培養する。培養後、細胞や組織を採取し、total RNAを抽出後、定量的real-time PCRを用いて、細胞周期に関係するCiclinD1の活性化、細胞増殖、アポトーシスを解析している。薬剤の作用メカニズムを考慮しながら、Rochester大学と連携しながら、候補薬剤をさらに絞り込もうとしているところである。
