(Summary) Head and neck squamous cell carcinoma (HNSCC) is a significant healthcare burden globally. Previous research using single-cell transcriptome analysis identified TGFBI as a crucial marker for the partial-epithelial-mesenchymal transition (partial-EMT) program. However, the precise role of TGFBI in HNSCC progression remains unclear. Therefore, our study aimed to clarify the impact of TGFBI on the malignant behavior of HNSCC cells. Through RNA-sequencing data from the TCGA database, we validated that increased TGFBI expression correlates with a higher occurrence of lymph node metastasis and unfavorable prognosis in HNSCC cases. Functional experiments demonstrated that TGFBI overexpression enhances the ability of sphere formation, indicating stem-cell-like properties. Conversely, TGFBI depletion reduces sphere formation and suppresses the expression of cancer stem cell (CSC) markers. RNA-sequencing analysis of TGFBI-overexpressing and control HNSCC cells revealed TAGLN as a downstream effector mediating TGFBI-induced sphere formation. Remarkably, TAGLN depletion abolished TGFBI-induced sphere formation, while its overexpression rescued the suppressed sphere formation caused by TGFBI depletion. Moreover, elevated TAGLN expression showed correlations with the expression of TGFBI and partial-EMT-related genes in HNSCC cases. In conclusion, our findings suggest that TGFBI may promote CSC properties through the upregulation of TAGLN. These novel insights shed light on the involvement of the TGFBI-TAGLN axis in HNSCC progression and hold implications for the development of targeted therapies.

(Summary) It recently has been reported that partial-epithelial-mesenchymal transition (p-EMT) program is associated with metastasis in head and neck squamous cell carcinoma (HNSCC). We previously have identified POSTN (which encodes periostin) as an invasion-promoting molecule in HNSCC. Interestingly, POSTN expression is frequently observed in cancer cells with higher p-EMT score by using a previous single-cell transcriptomic data of HNSCC cases. Although it is known that POSTN has 11 splicing variants, the role of them has not been determined in HNSCC. Here, we found that HNSCC cells with EMT features expressed POSTN isoforms, Iso3 (lacking exon 17 and 21) and Iso5 (lacking exon 17), whereas fibroblast expressed Iso3 and Iso4 (lacking exon 17, 18, and 21). The expression of POSTN Iso3 and Iso4 are known to be widely observed in various cell types including stromal cells. Therefore, we focused on the role of novel cancer cell-derived POSTN isoform, Iso5, in HNSCC. Single overexpression of POSTN Iso5 as well as Iso3 promoted invasion. Surprisingly, Iso5 synergistically promoted invasion together with Iso3. Notably, Iso5 as well as Iso3 upregulated p-EMT-related genes. We suggest that a novel cancer-specific POSTN isoform lacking exon 17 (Iso5) can be a useful marker for detecting cancer cells undergoing p-EMT. Moreover, a POSTN Iso5 can be a novel target for diagnosis and therapy in HNSCC.

Animal, Vol.58, No.8, 693-701, 2022. (Summary) Dental implants made of titanium are commonly used. Although titanium implants succeed by osseointegration with bone, the detailed molecular mechanism of osseointegration is unclear. To clarify the involvement of microRNA (miRNA) in the acquisition of osseointegration on titanium, here we compared the miRNA expression profiles of mouse osteoblast-like cells (MC3T3-E1) cultured on titanium-, gold-, and stainless steel-coating glass dishes by microarray analysis. Three kinds of metals, namely titanium, gold, and stainless steel, were coated on the surface of the glass dishes by sputtering with similar roughness and shape of their surface. After MC3T3-E1 cells were cultured on the dishes without coating or coating with titanium, gold, or stainless steel for 6 h, total RNA was extracted, and miRNA expression was analyzed by microarray. To confirm the expression of the selected miRNA during osteogenic differentiation of MC3T3-E1 cells, real-time PCR analysis was performed. Furthermore, the effects of selected miRNA were examined by ectopic overexpression in MC3T3-E1 cells. The microarray analysis revealed that the expressions of miR-155-5p and miR-7023-3p were significantly increased in MC3T3-E1 cells cultured on titanium-coating glass dishes, compared to non-coating, gold-, and stainless steel-coating glass dishes. Interestingly, miR-155-5p was upregulated during osteogenic differentiation of MC3T3-E1 cells. Furthermore, overexpression of miR-155-5p enhanced the expression of Runx2 and Col1a1. In this study, miR-155-5p may be involved in the acquisition of osseointegration on titanium implant via upregulating osteogenic differentiation-related genes.

(Summary) The ability of cancer cells to undergo partial-epithelial mesenchymal transition (p-EMT), rather than complete EMT, poses a higher metastatic risk. Although Fusobacterium nucleatum mainly inhabits in oral cavity, attention has been focused on the F. nucleatum involvement in colorectal cancer development. Here we examined the p-EMT regulation by F. nucleatum in oral squamous cell carcinoma (OSCC) cells. We cultured OSCC cells with epithelial, p-EMT or EMT phenotype with live or heat-inactivated F. nucleatum. Expression of the genes involved in epithelial differentiation, p-EMT and EMT were examined in OSCC cells after co-culture with F. nucleatum by qPCR. Cell growth and invasion of OSCC cells were also examined. Both live and heat-inactivated F. nucleatum upregulated the expression of p-EMT-related genes in OSCC cells with epithelial phenotype, but not with p-EMT or EMT phenotype. Moreover, F. nucleatum promoted invasion of OSCC cells with epithelial phenotype. Co-culture with other strains of bacteria other than Porphyromonas gingivalis did not alter p-EMT-related genes in OSCC cells with epithelial phenotype. F. nucleatum infection may convert epithelial to p-EMT phenotype via altering gene expression in OSCC. Oral hygiene managements against F. nucleatum infection may contribute to reduce the risk for an increase in metastatic ability of OSCC.

Moreover, HNSCC cells with p-EMT phenotype can be a useful model for investigating a nature of p-EMT.

(Summary) Autoimmunity is prevented by the function of the autoimmune regulator [AIRE (Aire in mice)], which promotes the expression of a wide variety of tissue-restricted antigens (TRAs) from medullary thymic epithelial cells (mTECs) and from a subset of peripheral antigen-presenting cells (APCs). We examined the effect of additive expression of human AIRE (huAIRE) in a model of autoimmune diabetes in NOD mice. Unexpectedly, we observed that mice expressing augmented AIRE/Aire developed muscle-specific autoimmunity associated with incomplete maturation of mTECs together with impaired expression of Aire-dependent TRAs. This led to failure of deletion of autoreactive T cells together with dramatically reduced production of regulatory T cells in the thymus. In peripheral APCs, expression of costimulatory molecules was augmented. We suggest that levels of Aire expression need to be tightly controlled for maintenance of immunological tolerance. Our results also highlight the importance of coordinated action between central tolerance and peripheral tolerance under the common control of Aire.

Yasuhiro Mouri, Yoshihiro Ueda, Tomoyoshi Yamano, Minoru Matsumoto, Koichi Tsuneyama, Tatsuo Kinashi and Mitsuru Matsumoto : Mode of tolerance induction and requirement for Aire are governed by the cell types that express self-antigen and those that present antigen, The Journal of Immunology, Vol.199, No.12, 3959-3971, 2017. (Summary) Aire controls the fate of autoreactive thymocytes (i.e., clonal deletion or development into regulatory T cells [Tregs]) through transcriptional control of the expression of tissue-restricted self-antigens (TRAs) from medullary thymic epithelial cells (mTECs) and bone marrow (BM)-derived cells. Although TRAs expressed by mTECs and BM-derived cells are suggested to complement each other to generate a full spectrum of TRAs, little is known about the relative contribution of TRAs from each component for establishment of self-tolerance. Furthermore, the precise role of Aire in specific types of Aire-expressing APCs remains elusive. We have approached these issues by generating two different types of transgenic mouse (Tg) model, which express a prefixed model self-antigen driven by the insulin promoter or the Aire promoter. In the insulin-promoter Tg model, mTECs alone were insufficient for clonal deletion, and BM-derived APCs were required for this action by utilizing Ag transferred from mTECs. In contrast, mTECs alone were able to induce Tregs, although at a much lower efficiency in the absence of BM-derived APCs. Importantly, lack of Aire in mTECs, but not in BM-derived APCs, impaired both clonal deletion and production of Tregs. In the Aire-promoter Tg model, both mTECs and BM-derived APCs could independently induce clonal deletion without Aire, and production of Tregs was impaired by the lack of Aire in mTECs, but not in BM-derived APCs. These results suggest that the fate of autoreactive thymocytes together with the requirement for Aire depend on the cell types that express self-antigens and the types of APCs involved in tolerance induction.

(Summary) Aire in medullary thymic epithelial cells (mTECs) plays an important role in the establishment of self-tolerance. Because Aire+ mTECs appear to be a limited subset, they may constitute a unique lineage(s) among mTECs. An alternative possibility is that all mTECs are committed to express Aire in principle, but Aire expression by individual mTECs is conditional. To investigate this issue, we established a novel Aire reporter strain in which endogenous Aire is replaced by the human AIRE-GFP-Flag tag (Aire/hAGF-knockin) fusion gene. The hAGF reporter protein was produced and retained very efficiently within mTECs as authentic Aire nuclear dot protein. Remarkably, snapshot analysis revealed that mTECs expressing hAGF accounted for >95% of mature mTECs, suggesting that Aire expression does not represent a particular mTEC lineage(s). We confirmed this by generating Aire/diphtheria toxin receptor knockin mice in which long-term ablation of Aire+ mTECs by diphtheria toxin treatment resulted in the loss of most mature mTECs beyond the proportion of those apparently expressing Aire. These results suggest that Aire expression is inherent to all mTECs but may occur at particular stage(s) and/or cellular states during their differentiation, thus accounting for the broad impact of Aire on the promiscuous gene expression of mTECs.

(Summary) Cortical thymic epithelial cells (cTECs) and medullary thymic epithelial cells (mTECs) play essential roles in the positive and negative selection of developing thymocytes, respectively. Aire in mTECs plays an essential role in the latter process through expression of broad arrays of tissue-restricted Ags. To determine whether the location of Aire within the medulla is absolutely essential or whether Aire could also function within the cortex for establishment of self-tolerance, we used bacterial artificial chromosome technology to establish a semiknockin strain of NOD-background (β5t/Aire-transgenic) mice expressing Aire under control of the promoter of β5t, a thymoproteasome expressed exclusively in the cortex. Although Aire was expressed in cTECs as typical nuclear dot protein in β5t/Aire-Tg mice, cTECs expressing Aire ectopically did not confer transcriptional expression of either Aire-dependent or Aire-independent tissue-restricted Ag genes. We then crossed β5t/Aire-Tg mice with Aire-deficient NOD mice, generating a strain in which Aire expression was confined to cTECs. Despite the presence of Aire(+) cTECs, these mice succumbed to autoimmunity, as did Aire-deficient NOD mice. The thymic microenvironment harboring Aire(+) cTECs, within which many Aire-activated genes were present, also showed no obvious alteration of positive selection, suggesting that Aire's unique property of generating a self-tolerant T cell repertoire is functional only in mTECs.

(Summary) Essential roles of NF-κB-inducing kinase (NIK) for the development of medullary thymic epithelial cells (mTECs) and regulatory T cells have been highlighted by studies using a strain of mouse bearing a natural mutation of the NIK gene (aly mice). However, the exact mechanisms underlying the defect in thymic cross-talk leading to the breakdown of self-tolerance in aly mice remain elusive. In this study, we demonstrated that production of regulatory T cells and the final maturation process of positively selected conventional αβ T cells are impaired in aly mice, partly because of a lack of mature mTECs. Of note, numbers of thymic dendritic cells and their expression of costimulatory molecules were also affected in aly mice in a thymic stroma-dependent manner. The results suggest a pivotal role of NIK in the thymic stroma in establishing self-tolerance by orchestrating cross-talk between mTECs and dendritic cells as well as thymocytes. In addition, we showed that negative selection was impaired in aly mice as a result of the stromal defect, which accounts for the development of organ-specific autoimmunity through a lack of normal NIK.

(Summary) Understanding the cellular dynamics of Aire-expressing lineage(s) among medullary thymic epithelial cells (AEL-mTECs) is essential for gaining insight into the roles of Aire in establishment of self-tolerance. In this study, we monitored the maturation program of AEL-mTECs by temporal lineage tracing, in which bacterial artificial chromosome transgenic mice expressing tamoxifen-inducible Cre recombinase under control of the Aire regulatory element were crossed with reporter strains. We estimated that the half-life of AEL-mTECs subsequent to Aire expression was ∼7-8 d, which was much longer than that reported previously, owing to the existence of a post-Aire stage. We found that loss of Aire did not alter the overall lifespan of AEL-mTECs, inconsistent with the previous notion that Aire expression in medullary thymic epithelial cells (mTECs) might result in their apoptosis for efficient cross-presentation of self-antigens expressed by AEL-mTECs. In contrast, Aire was required for the full maturation program of AEL-mTECs, as exemplified by the lack of physiological downregulation of CD80 during the post-Aire stage in Aire-deficient mice, thus accounting for the abnormally increased CD80(high) mTECs seen in such mice. Of interest, increased CD80(high) mTECs in Aire-deficient mice were not mTEC autonomous and were dependent on cross-talk with thymocytes. These results further support the roles of Aire in the differentiation program of AEL-mTECs.

However, details of the mechanism responsible for the unique and cooperative action of individual and multiple TNFR superfamily members during mTEC differentiation still remain enigmatic. In this study, we show that the LTβR signal upregulates expression of RANK in the thymic stroma, thereby promoting accessibility to the RANK ligand necessary for mTEC differentiation. Cooperation between the LTβR and RANK signals for optimal mTEC differentiation was underscored by the exaggerated defect of thymic organogenesis observed in mice doubly deficient for these signals. In contrast, we observed little cooperation between the LTβR and CD40 signals. Thus, the LTβR signal exhibits a novel and unique function in promoting RANK activity for mTEC organization, indicating a link between thymic organogenesis mediated by multiple cytokine signals and the control of autoimmunity.

(Summary) The roles of autoimmune regulator (Aire)-expressing medullary thymic epithelial cells (mTECs) in the organization of the thymic microenvironment for establishing self-tolerance are enigmatic. We sought to monitor the production and maintenance of Aire-expressing mTECs by a fate-mapping strategy in which bacterial artificial chromosome transgenic (Tg) mice expressing Cre recombinase under the control of the Aire regulatory element were crossed with a GFP reporter strain. We found that, in addition to its well recognized expression within mature mTECs, Aire was expressed in the early embryo before emergence of the three germ cell layers. This observation may help to explain the development of ectodermal dystrophy often seen in patients with AIRE deficiency. With the use of one Tg line in which Cre recombinase expression was confined to mTECs, we found that Aire(+)CD80(high) mTECs further progressed to an Aire(-)CD80(intermediate) stage, suggesting that Aire expression is not constitutive from after its induction until cell death but instead is down-regulated at the beginning of terminal differentiation. We also demonstrated that many mTECs of Aire-expressing lineage are in close contact with thymic dendritic cells. This close proximity may contribute to transfer of tissue-restricted self-antigens expressed by mTECs to professional antigen-presenting cells.

(Summary) The roles of autoimmune regulator (Aire) in the expression of the diverse arrays of tissue-restricted antigen (TRA) genes from thymic epithelial cells in the medulla (medullary thymic epithelial cells [mTECs]) and in organization of the thymic microenvironment are enigmatic. We approached this issue by creating a mouse strain in which the coding sequence of green fluorescent protein (GFP) was inserted into the Aire locus in a manner allowing concomitant disruption of functional Aire protein expression. We found that Aire(+) (i.e., GFP(+)) mTECs were the major cell types responsible for the expression of Aire-dependent TRA genes such as insulin 2 and salivary protein 1, whereas Aire-independent TRA genes such as C-reactive protein and glutamate decarboxylase 67 were expressed from both Aire(+) and Aire(-) mTECs. Remarkably, absence of Aire from mTECs caused morphological changes together with altered distribution of mTECs committed to Aire expression. Furthermore, we found that the numbers of mTECs that express involucrin, a marker for terminal epidermal differentiation, were reduced in Aire-deficient mouse thymus, which was associated with nearly an absence of Hassall's corpuscle-like structures in the medulla. Our results suggest that Aire controls the differentiation program of mTECs, thereby organizing the global mTEC integrity that enables TRA expression from terminally differentiated mTECs in the thymic microenvironment.

(Summary) Factors that determine the spectrum of target organs involved in autoimmune destruction are poorly understood. Although loss of function of autoimmune regulator (AIRE) in thymic epithelial cells is responsible for autoimmunity, the pathogenic roles of AIRE in regulating target-organ specificity remain elusive. In order to gain insight into this issue, we have established NOD mice, an animal model of type 1 diabetes caused by autoimmune attack against beta cell islets, in which Aire has been abrogated. Remarkably, acinar cells rather than beta cell islets were the major targets of autoimmune destruction in Aire-deficient NOD mice, and this alteration of intra-pancreatic target-organ specificity was associated with production of autoantibody against pancreas-specific protein disulfide isomerase (PDIp), an antigen expressed predominantly by acinar cells. Consistent with this pathological change, the animals were resistant to the development of diabetes. The results suggest that Aire not only is critical for the control of self-tolerance but is also a strong modifier of target-organ specificity through regulation of T cell repertoire diversification. We also demonstrated that transcriptional expression of PDIp was retained in the Aire-deficient NOD thymus, further supporting the concept that Aire may regulate the survival of autoreactive T cells beyond transcriptional control of self-protein expression in the thymus.

(Summary) IkappaB kinase (IKK) alpha exhibits diverse biological activities through protein kinase-dependent and -independent functions, the former mediated predominantly through a noncanonical NF-kappaB activation pathway. The in vivo function of IKKalpha, however, still remains elusive. Because a natural strain of mice with mutant NF-kappaB-inducing kinase (NIK) manifests autoimmunity as a result of disorganized thymic structure with abnormal expression of Rel proteins in the thymic stroma, we speculated that the NIK-IKKalpha axis might constitute an essential step in the thymic organogenesis that is required for the establishment of self-tolerance. An autoimmune disease phenotype was induced in athymic nude mice by grafting embryonic thymus from IKKalpha-deficient mice. The thymic microenvironment that caused autoimmunity in an IKKalpha-dependent manner was associated with defective processing of NF-kappaB2, resulting in the impaired development of thymic epithelial cells. Thus, our results demonstrate a novel function for IKKalpha in thymic organogenesis for the establishment of central tolerance that depends on its protein kinase activity in cooperation with NIK.

(Summary) Autoimmune regulator (AIRE) gene mutation is responsible for the development of organ-specific autoimmune disease with monogenic autosomal recessive inheritance. Although Aire has been considered to regulate the elimination of autoreactive T cells through transcriptional control of tissue-specific Ags in thymic epithelial cells, other mechanisms of AIRE-dependent tolerance remain to be investigated. We have established Aire-deficient mice and examined the mechanisms underlying the breakdown of self-tolerance. The production and/or function of immunoregulatory T cells were retained in the Aire-deficient mice. The mice developed Sjogren's syndrome-like pathologic changes in the exocrine organs, and this was associated with autoimmunity against a ubiquitous protein, alpha-fodrin. Remarkably, transcriptional expression of alpha-fodrin was retained in the Aire-deficient thymus. These results suggest that Aire regulates the survival of autoreactive T cells beyond transcriptional control of self-protein expression in the thymus, at least against this ubiquitous protein. Rather, Aire may regulate the processing and/or presentation of self-proteins so that the maturing T cells can recognize the self-Ags in a form capable of efficiently triggering autoreactive T cells. With the use of inbred Aire-deficient mouse strains, we also demonstrate the presence of some additional factor(s) that determine the target-organ specificity of the autoimmune disease caused by Aire deficiency.

(Summary) The discovery of Aire-dependent transcriptional control of many tissue-restricted self-antigen (TRA) genes in thymic epithelial cells in the medulla (medullary thymic epithelial cells, mTECs) has raised the intriguing question of how the single Aire gene can influence the transcription of such a large number of TRA genes within mTECs. From a mechanistic viewpoint, there are two possible models to explain the function of Aire in this action. In the first model, TRAs are considered to be the direct target genes of Aire's transcriptional activity. In this scenario, the lack of Aire protein within cells would result in the defective TRA gene expression, while the maturation program of mTECs would be unaffected in principle. The second model hypothesizes that Aire is necessary for the maturation program of mTECs. In this case, we assume that the mTEC compartment does not mature normally in the absence of Aire. If acquisition of the properties of TRA gene expression depends on the maturation status of mTECs, a defect of such an Aire-dependent maturation program in Aire-deficient mTECs can also result in impaired TRA gene expression. In this brief review, we will focus on these two contrasting models for the roles of Aire in controlling the expression of TRAs within mTECs.
