Abstract
In recent years, immunotherapy has become a standard cancer therapy, joining surgery, chemotherapy, and radiation therapy. This therapeutic approach involves the use of patient-derived antigen-specific T cells or genetically modified T cells engineered with chimeric antigen receptors (CAR) or T cell receptors (TCR) that specifically target cancer antigens. However, T cells require ex vivo stimulation for proliferation when used in therapy, and the resulting "exhaustion," which is characterized by a diminished proliferation capacity and anti-tumor activity, poses a significant challenge. As a solution, we reported "rejuvenated" CD8 + T cells that possess high proliferation capacity from induced pluripotent stem cells (iPSCs) in 2013. This review discusses the status and future developments in immunotherapy using iPSC-derived T cells, drawing insights from our research to overcome the exhaustion associated with antigen-specific T cell therapy.

Abstract
ABSTRACT A major hurdle in adoptive T-cell therapy is cell exhaustion and failure to maintain antitumor responses. Here, we introduce an induced pluripotent stem cell (iPSC) strategy for reprogramming and revitalizing precursor exhausted B-cell maturation antigen (BCMA)-specific T cells to effectively target multiple myeloma (MM). Heteroclitic BCMA72-80 (YLMFLLRKI)-specific CD8+ memory cytotoxic T lymphocytes (CTL) were epigenetically reprogrammed to a pluripotent state, developed into hematopoietic progenitor cells (CD34+ CD43+/CD14- CD235a-), differentiated into the T-cell lineage and evaluated for their polyfunctional activities against MM. The final T-cell products demonstrated (1) mature CD8αβ+ memory phenotype, (2) high expression of activation or costimulatory molecules (CD38, CD28, and 41BB), (3) no expression of immune checkpoint and senescence markers (CTLA4, PD1, LAG3, and TIM3; CD57), and (4) robust proliferation and polyfunctional immune responses to MM. The BCMA-specific iPSC-T cells possessed a single T-cell receptor clonotype with cognate BCMA peptide recognition and specificity for targeting MM. RNA sequencing analyses revealed distinct genome-wide shifts and a distinctive transcriptional profile in selected iPSC clones, which can develop CD8αβ+ memory T cells. This includes a repertoire of gene regulators promoting T-cell lineage development, memory CTL activation, and immune response regulation (LCK, IL7R, 4-1BB, TRAIL, GZMB, FOXF1, and ITGA1). This study highlights the potential application of iPSC technology to an adaptive T-cell therapy protocol and identifies specific transcriptional patterns that could serve as a biomarker for selection of suitable iPSC clones for the successful development of antigen-specific CD8αβ+ memory T cells to improve the outcome in patients with MM.

Abstract
Introduction T cells induced from induced pluripotent stem cells(iPSCs) derived from antigen-specific T cells (T-iPS-T cells) are an attractive tool for T cell immunotherapy. The induction of cytotoxic T-iPS-T cells is well established in feeder-free condition for the aim of off-the-shelf production, however, the induction of helper T-iPS-T cells remains challenging. Methods We analyzed T-iPS-T cells matured in 3D organoid culture at different steps in the culture process at the single-cell level. T-iPS-T cell datasets were merged with an available human thymocyte dataset based in single-cell RNA sequencing (scRNA-seq). Particularly, we searched for genes crucial for generation CD4+ T-iPS-T cells by comparing T-iPS-T cells established in 2D feeder-free or 3D organoid culture. Results The scRNA-seq data indicated that T-iPS-T cells are similar to T cells transitioning to human thymocytes, with SELENOW, GIMAP4, 7, SATB1, SALMF1, IL7R, SYTL2, S100A11, STAT1, IFITM1, LZTFL1 and SOX4 identified as candidate genes for the 2D feeder-free induction of CD4+ T-iPS-T cells. Discussion This study provides single cell transcriptome datasets of iPS-T cells and leads to further analysis for CD4+ T cell generation from T-iPSCs.

Abstract
Allogeneic T cell platforms utilizing induced pluripotent stem cell (iPSC) technology exhibit significant promise for the facilitation of adoptive immunotherapies. While mature T cell receptor (TCR) signaling plays a crucial role in generating T cells from iPSCs, the introduction of exogenous mature TCR genes carries a potential risk of causing graft-versus-host disease (GvHD). In this study, we present the development of truncated TCRα and TCRβ chains, termed mini-TCRs, which lack variable domains responsible for recognizing human leukocyte antigen (HLA)-peptide complexes. We successfully induced cytotoxic T lymphocytes (CTLs) from iPSCs by employing mini-TCRs. Combinations of TCRα and TCRβ fragments were screened from mini-TCR libraries based on the surface localization of CD3 proteins and their ability to transduce T cell signaling. Consequently, mini-TCR-expressing iPSCs underwent physiological T cell development, progressing from the CD4 and CD8 double-positive stage to the CD8 single-positive stage. The resulting iPSC-derived CTLs exhibited comparable cytokine production and cytotoxicity in comparison to that of full-length TCR-expressing T lymphocytes when chimeric antigen receptors (CARs) were expressed. These findings demonstrate the potential of mini-TCR-carrying iPSCs as a versatile platform for CAR T cell therapy, offering a promising avenue for advancing adoptive immunotherapies.

Abstract
Immune rejection of allogeneic cell therapeutics remains a major problem for immuno-oncology and regenerative medicine. Allogeneic cell products so far have inferior persistence and efficacy when compared with autologous alternatives. Engineering of hypoimmune cells may greatly improve their therapeutic benefit. We present a new class of agonistic immune checkpoint engagers that protect human leukocyte antigen (HLA)-depleted induced pluripotent stem cell-derived endothelial cells (iECs) from innate immune cells. Engagers with agonistic functionality to their inhibitory receptors TIM3 and SIRPα effectively protect engineered iECs from natural killer (NK) cell and macrophage killing. The SIRPα engager can be combined with truncated CD64 to generate fully immune evasive iECs capable of escaping allogeneic cellular and immunoglobulin G (IgG) antibody-mediated rejection. Synthetic immune checkpoint engagers have high target specificity and lack retrograde signaling in the engineered cells. This modular design allows for the exploitation of more inhibitory immune pathways for immune evasion and could contribute to the advancement of allogeneic cell therapeutics.

Abstract
In recent years, cell-based immunotherapies, such as chimeric antigen receptor(CAR)-T cell therapy, have greatly advanced the treatment of some hematological malignancies, especially those resistant to other therapies. Nevertheless, there are significant obstacles to the clinical application of current autologous therapies, such as high cost, challenging large-scale manufacturing, and difficulty obtaining long-term therapeutic efficacy due to T cell exhaustion. Induced pluripotent stem(iPS)cells have the potential to solve these problems through their unlimited proliferative capacity and differentiation potency to every type of cell in a body. Furthermore, iPS cells can be genetically engineered and differentiated into various types of immune cells, providing an unlimited resource for the development of"off-the-shelf"cell therapies. Here, we review the clinical development status of regenerative immunotherapies using iPS cell-derived CD8 killer T cells and natural killer(NK)cells and outline regenerative immunotherapies using natural killer T(NKT)cells, γδ T cells, mucosal-associated invariant T(MAIT)cells, and macrophages.

Abstract
Human induced pluripotent stem cells (hiPSCs) genetically depleted of human leucocyte antigen (HLA) class I expression can bypass T cell alloimmunity and thus serve as a one-for-all source for cell therapies. However, these same therapies may elicit rejection by natural killer (NK) cells, since HLA class I molecules serve as inhibitory ligands of NK cells. Here, we focused on testing the capacity of endogenously developed human NK cells in humanized mice (hu-mice) using MTSRG and NSG-SGM3 strains to assay the tolerance of HLA-edited iPSC-derived cells. High NK cell reconstitution was achieved with the engraftment of cord blood-derived human hematopoietic stem cells (hHSCs) followed by the administration of human interleukin-15 (hIL-15) and IL-15 receptor alpha (hIL-15Rα). Such "hu-NK mice" rejected HLA class I-null hiPSC-derived hematopoietic progenitor cells (HPCs), megakaryocytes and T cells, but not HLA-A/B-knockout, HLA-C expressing HPCs. To our knowledge, this study is the first to recapitulate the potent endogenous NK cell response to non-tumor HLA class I-downregulated cells in vivo. Our hu-NK mouse models are suitable for the non-clinical evaluation of HLA-edited cells and will contribute to the development of universal off-the-shelf regenerative medicine.

Abstract
The effectiveness of chimaeric antigen receptor (CAR) T-cell immunotherapies against solid tumours relies on the accumulation, proliferation and persistency of T cells at the tumour site. Here we show that the proliferation of CD8αβ cytotoxic CAR T cells in solid tumours can be enhanced by deriving and expanding them from a single human induced-pluripotent-stem-cell clone bearing a CAR selected for efficient differentiation. We also show that the proliferation and persistency of the effector cells in the tumours can be further enhanced by genetically knocking out diacylglycerol kinase, which inhibits antigen-receptor signalling, and by transducing the cells with genes encoding for membrane-bound interleukin-15 (IL-15) and its receptor subunit IL-15Rα. In multiple tumour-bearing animal models, the engineered hiPSC-derived CAR T cells led to therapeutic outcomes similar to those of primary CD8 T cells bearing the same CAR. The optimization of effector CAR T cells derived from pluripotent stem cells may aid the development of long-lasting antigen-specific T-cell immunotherapies for the treatment of solid tumours.

Abstract
Recently, research has been conducted with chimeric antigen receptor (CAR)-T cells to improve efficacy against solid tumors. Humanized CAR improved the long-term survival of CAR-T cells in patients' peripheral blood, resulting in increased therapeutic efficacy. Therefore, the humanization of the CAR-gene sequence is considered an effective method. Podoplanin (PDPN) is a glycosylated transmembrane protein that is highly expressed in solid tumors and is associated with poor prognosis in patients with cancer. Therefore, PDPN is considered a biomarker and good target for cancer treatment with CAR-T cells. Previously, an anti-PDPN CAR was generated from a conventional non-humanized antibody-NZ-1, the only anti-PDPN antibody for which a CAR was produced. In this study, we investigated other anti-PDPN CARs from the antibody NZ-27, or humanized NZ-1, to enhance the therapeutic potential of CAR-T cells. The CAR signal intensity was enhanced by the efficient expression of CAR proteins on the T-cell surface of NZ-27 CAR-T cells, which show tumor-specific cytotoxicity, proinflammatory cytokine production, and anti-tumor activity against PDPN-expressing tumor xenografts in mice that were significantly better than those in non-humanized NZ-1 CAR-T cells.

Abstract
Abstract
Study question
What are the similarities and differences between the morphokinetics of abnormal, one- (1PN) and three-pronuclear (3PN) and normal bi-pronuclear (2PN) fertilisation?
Summary answer
The morphokinetic analysis of 1PN/3PN fertilisation reveals novel aspects of abnormal early development.
What is known already
Assisted reproduction technology has allowed the observation of early human development. Initially assessed statically at a single time point, fertilization has revealed its complexity once observed by Time-Lapse Microscopy (TLM). Detailed morphokinetic analysis of fertilisation has been reported in the last few years, unveiling previously unknown cytoplasmic phenomena (e.g. the cytoplasmic wave and halo) and the importance of cell symmetry for embryo development. At present, abnormal fertilization remains neglected, despite potential for understanding the physiology and pathology of early human development.
Study design, size, duration
This retrospective study involved TLM observation of normally (2PN, n = 2,685) and abnormally (1PN, n = 41; 3PN, n = 127) fertilised oocytes generated in ICSI cycles. Oocyte retrievals were carried out after the clomiphene citrate-based minimal ovarian stimulation, between October 2019 and December 2020. Oocytes of patients with different diagnoses of infertility were included in the analysis, while cases involving cryopreserved gametes or surgically retrieved sperm were excluded.
Participants/materials, setting, methods
Microinjected oocytes were assessed by a combined TLM-culture system (Embryoscope). Oocytes not suitable for TLM assessment, due to excess of residual corona cells or inadequate orientation for correct observation, were not analysed. Phenomena, relevant to meiotic resumption, pronuclear dynamics, cytoplasmic/cortical modifications, cleavage pattern, and embryo quality, were annotated and compared between groups.
Main results and the role of chance
Second polar body (PBII) extrusion was observed in all 1PN- and in a majority of 3PN-zygotes (92.1%). A 0.3-hour delay in PBII extrusion was confirmed in 3PN-zygotes (P = 0.0439). In a significant proportion of 3PN-zygotes, a third (female) PN formed from reabsorption of the PBII. The cytoplasmic wave was observed not only in 2PN- and 3PN-, but also in 1PN-zygotes. The presence and position of cytoplasmic halo were comparable among the three classes of zygotes. However, the duration of the cytoplasmic halo was prolonged in 1PN-zygotes (P < 0.0001). PN juxtaposition immediately before PN breakdown was less frequent in 3PN- compared with 2PN-zygotes (P = 0.0159). Furthermore, asynchronous PN breakdown was increased in 3PN- compared with 2PN-zygotes (P = 0.0026). The PN area of 1PN- was larger than that of 2PN-zygotes; however, the PN area of 3PN-zygotes was smaller than that of 2PN-zygotes. In 1PN-zygotes, a developmental delay was observed starting from the disappearance of the cytoplasmic halo, reaching 9 hours at the time of cleavage (P < 0.0001). A higher incidence of abnormal cleavage (P = 0.0019) and blastomere fragmentation (P < 0.0001) was observed in 1PN-zygotes. Cleavage progression was increasingly affected especially in 1PN-zygotes, resulting in blastocyst formation rates of 70.2%, 12.2% and 53.5% in 2PN-, 1PN- and 3PN-zygotes, respectively (P < 0.0001).
Limitations, reasons for caution
The study data derive from treatments carried out in a single centre. The study findings therefore require independent verification from other research groups.
Wider implications of the findings
These observations suggest that 1PN and 3PN fertilisation follow the general pattern of normal fertilization. Crucially, they also shed light on diverse and previously undescribed phenomena - e.g. reabsorption of the PBII in 3PN zygotes - underpinning the origins of abnormal fertilization and potentially clinically relevant.

Abstract
Abstract
T cell regenerative medicine represents an immunotherapeutic approach using antigen-specific induced Pluripotent Stem Cells (iPSC) to rejuvenate CD8+ cytotoxic T lymphocytes (CTL). Here, we report an iPSC-derived therapeutic strategy targeting B-Cell Maturation Antigen (BCMA) to overcome exhaustion of antigen-specific CTL and revitalize them to fully functional antigen-specific memory T cells to target multiple myeloma (MM). First, we established the iPSC by reprogramming IFN-γ producing heteroclitic BCMA72-80 (YLMFLLRKI) peptide-specific CD8+ CTL via Sendai virus transduction of transcription factors, OCT3/4, SOX2, KLF4 and c-MYC. The BCMA-specific iPSC demonstrated high pluripotency potential and ability to differentiate into three key germ layers, as evidenced by expression of stem cell markers (SSEA-4, TRA1-60), germ differentiation markers (SOX-17 on Endoderm, Brachyury on Mesoderm, and Pax-6 on Ectoderm) and alkaline phosphatase. The polarization of iPSC was followed during embryoid body formation into mesoderm development, evidenced by activation of transcriptional regulators SNAI2, TBX3, PLVAP, HAND1 and CDX2. Furthermore, hematopoietic progenitor cells (HPC; CD34+ CD43+/CD14- CD235a-) were sorted and induced to undergo T cell development under feeder-free culture conditions in the presence of rectonectin. Upon differentiation, phenotypic characterization revealed fully mature T cells with high expression (> 95%) of CD3, CD45, TCRαβ and CD8αβ, which were predominantly CD45RO+ memory T cells with high activation (CD38) and costimulatory (CD28) molecule expression, while lacking immune checkpoints (CTLA4, PD1, LAG3, Tim3). This phenotype was aligned with their high proliferative (1,800-fold increase) capacity and effective anti-tumor cytotoxicity and Th1 cytokine (IFN-γ, IL-2, TNF-α) production against MM patients’ tumor cells in antigen-specific and HLA-A2-restricted manner. Their anti-MM activities were specifically directed against the parent heteroclitic BCMA72-80 peptide via a distinct sole T cell receptor clonotype. RNAseq analyses identified specific transcriptional pathways utilized by BCMA-specific HPC during their differentiation into CD8+ CTL, which include upregulation of transcriptional regulators determining CD4/CD8 T cell differentiation ratio, memory CTL formation, NF-kappa-B/JNK pathway activation, as well as downregulation of regulators controlling B and T cell interactions or CD4+ Th cells and inhibitory receptor development. In summary, these results highlight the processes and pathways mediating somatic T cell epigenetic reprogramming and differentiation into rejuvenated BCMA-specific CD8+ CTL with high proliferation and functional anti-MM activities, providing the framework for regenerative medicine as an adoptive immunotherapy to improve patient outcome in MM.

Abstract
Abstract
Background: The development of chimeric antigen receptor (CAR) T cell therapy has introduced an effective strategy to guide and promote the immune response. Also, gene-engineering NK cells to express an exogenous CAR receptor allows the innate anti-tumor ability of NK cells to be directed against target tumor antigen. However, these autologous applications are limited by toxicities, restricted trafficking and infiltration into tumor, suboptimal persistence, and exhausted status of immune cells that may cause manufacturing failure. One approach to overcome those limitations is the development of “off-the-shelf” iPS-cell sources. The iCAR-ILC-N101 is an allogeneic human leukocyte antigen (HLA)-homozygous induced pluripotent stem cell (iPSC)-derived anti-glypican-3 (GPC3) CAR-expressing innate lymphoid cells/natural killer cell (ILC/NK), which has both antigen-specific and NK activating receptor-mediated cytotoxicity. The iCAR-ILC-N101 is produced from the established iPSC strain QHJI01s04, and there is theoretically no risk of developing graft-versus host disease because the product dose not have T cell receptor. The product has a relevant living period in the body, thereby has little concern about residual toxicity and reduces systemic side effects by topical treatment. GPC3 is a cancer-specific membranous protein that is expressed in hepatoblastoma, hepatocellular carcinoma and ovarian clear cell carcinoma (OCCC) but is not expressed in normal tissue. OCCC is a relatively rare malignancy and is associated with poor prognosis. Intraperitoneal administration of iCAR-ILC-N101 is expected to show antitumor activity for OCCC patients with peritoneal dissemination that express GPC3 and reduce systemic side effects, thereby ensuring safety and improving therapeutic efficacy. Preclinical study showed that intraperitoneal injection of iCAR-ILC-N101 for GPC3-positive ovarian tumor-bearing immunodeficient mouse model showed suppressed tumor growth.
Method: This is a first-in human phase 1 study to evaluate safety, toxicity and efficacy of the iCAR-ILC-N101 in patients with GPC3-positive advanced or recurrent OCCC harboring peritoneal dissemination. Major inclusion criteria include histologically diagnosed GPC3-positive advanced or recurrent OCCC with peritoneal dissemination who are resistant to standard therapy and have matched HLA-A24 or B52. The study includes 3 cohorts (cohort -1, 0.5x106 cells/kg; cohort 1, 1x106 cells/kg; cohort 2, 3x106 cells/kg) and starts with cohort 1. The iCAR-ILC-N101 is administered intraperitoneally once a week for 4 weeks; for the first patient in each cohort, patient is observed for 14 days for safety evaluation after the first administration and then receive iCAR-ILC-N101 on day15 and 22. Enrollment initiated in July 2021 and one patient was enrolled. No dose-limiting toxicity was observed. Clinical trial registry number: jRCT2033200431

Abstract
2542 Background: A strategy for reversal of T cell exhaustion is reprograming of antigen-specific CTL to early lineage memory T cells with selective anti-tumor activities. To accomplish this goal, we epigenetically reprogrammed BCMA-specific CD8+ CTL to a pluripotent state through key defined transcription factors, established “induced Pluripotent Stem Cells (iPSC)” exhibiting transcriptional and epigenetic features, re-differentiated them back into antigen-specific CTL and evaluated their properties and functional activities against multiple myeloma (MM). Methods: Functionally activeIFN-g producing HLA-A2 heteroclitic BCMA72-80 (YLMFLLRKI)-specific CD8+ CTL were applied for iPSC via transduction of four reprogramming factors (OCT3/4, SOX2, KLF4, c-MYC). Upon characterization of the BCMA-specific iPSC with high pluripotency potential, embryoid body was formed from the iPSC and further polarized into mesoderm layer development as evidenced by upregulation of transcriptional regulators (ABCA4, BMP10, CDH5, FOXF1, HAND1, PLVAP, SNAI2, TBX3). Next, BCMA-specific embryoid body-derived hematopoietic progenitor cells (HPC; CD34+ CD43+/CD14- CD235a-) were sorted and induced to undergo T cell differentiation in the presence of Fc-DLL4 signaling and rectonectin. Results: Our RNAseq analyses demonstrated unique transcriptional profiles of HPC from different iPSC clones committing to CD8+ T cells or other cell lineages (monocytes/granulocytes, B lymphocytes/NK cells). Principal component analyses demonstrated a high similarity and low variability of transcription profiles within the replicates of HPC committed to the same cell lineage. In addition, distinct genome-wide shifts and differential gene expression profiles were detected in HPC committed to each specific cell differentiation pathway. Specifically, the HPC commit to CD8+ T cells utilized a diverse repertoire of modulators promoting development of T cell maturation, specific immune response regulation, memory T cells, cytotoxicity and interferon induction, which were significantly higher than shown in HPC that differentiate to other cell lineages. In parallel, specific repression genes were identified in the HPC commit to CD8+ T cells, which develop TGF-β receptor, rearrangement of Ig heavy chain genes and inhibitory receptors. The T cells differentiated were mainly CD45RO+ memory CTL and fully rejuvenated without immune checkpoints expression and regulatory T cells and with high anti-MM activities. Conclusions: These findings identify genetic and epigenetic mechanisms and regulatory elements, which play key roles during lineage specific commitment of HPC developed in iPSC into CD8+ CTL and help to further design a next generation of regenerative medicine that provide the appropriate signals for T cell lineage commitment from progenitor cells.

Background/Introduction
A novel mapping algorithm recently became available in Europe and select countries in the Asia Pacific region. EnSite Omnipolar Technology (OT) utilizes the Advisor HD Grid Mapping Catheter, Sensor Enabled (HD Grid) to calculate electrograms in 360 degrees from two bipolar and three unipolar electrograms acquired from a triangular set of three electrodes. This software also enables calculation of wavefront characteristics including maximum voltage, activation direction and wave speed. Procedural characteristics and clinical utilization of this novel software have not yet been reported.
Purpose
To examine the clinical utility and procedural characteristics associated with the use of this novel mapping algorithm among participating centers.
Methods
Acute procedural data were prospectively collected in 386 cases at 52 centers utilizing the newly approved mapping software in the initial phases of commercialization in Europe and the Asia Pacific region. Procedural characteristics recorded included indication for mapping/ablation, navigation mode, mapping reference, and maps and tools used to diagnose/locate ablation targets.
Results
A total of 14 indications for mapping and ablation were represented including AF, atypical flutter, and VT (Table 1). VoXel (magnetic primary) navigation mode was used in most cases (n=325, 84%). The CS catheter was used as the map reference in 280 cases (73%). A variety of workflows were used with OT to diagnose and locate ablation targets including voltage maps (n=275, 71%), LAT maps (n=226, 59%), OT activation vectors (n=124, 32%), propagation maps (n=94, 24%), and sparkle maps (n=69, 18%); note: total exceeds 100%, multiple workflows per case observed. EnSite LiveView Dynamic Display (LiveView) was used in 129 cases (33%) to diagnose and locate ablation targets, including 28 (22%) where OT activation vectors were used with LiveView. Several benefits of OT were reported including rapid identification of ablation target(s) (n=133, 35%), higher point density (n=82, 21%), better signals (n=69, 18%), and improved procedure efficiency (n=48, 12%).
Conclusion(s)
Initial experience with this novel mapping software in Europe and the Asia-Pacific region illustrated utility in a variety of arrhythmias to diagnose and locate ablation targets. The use of OT provided several benefits including rapid identification of ablation targets and higher point density, however further examination of its impact on procedural efficiencies and acute outcomes is likely warranted.

Abstract
We study the critical dynamics of vortices associated with dynamic disordering near the depinning transitions driven by dc force (dc current I) and vortex density (magnetic field B). Independent of the driving parameters, I and B, we observe the critical behavior of the depinning transitions, not only on the moving side, but also on the pinned side of the transition, which is the first convincing verification of the theoretical prediction.

The critical exponents of both transitions are, within errors, identical to each other, which are in agreement with the values expected for an absorbing phase transition in the two-dimensional directed-percolation universality class. With an increase in B under constant I, the depinning transition at low B is replaced by the repinning transition at high B in the peak-effect regime. We find a trend that the critical exponents in the peak-effect regime are slightly smaller than those in the low-B regime and the theoretical one, which is attributed to the slight difference in the depinning mechanism in the peak-effect regime.

Abstract
CAR-T therapy has shown excellent therapeutic efficacy in B-cell malignancy. Nevertheless, manufacturing stability, quality control, and CAR T-cell availability are still challenging because current CAR T-cell therapy is a personalized product derived from patient peripheral T-cells. However, allogeneic T-cells have emerged as a novel source to overcome this issue. Because induced pluripotent stem (iPS) cells are pluripotent stem cells derived from somatic cells and have in vitro self-renewal ability and pluripotency, they are expected to be a source of many regenerative medicinal products. Recently, it has become possible to generate CD8 killer T cells from iPS cells, and efforts have been made to generate CAR-CD8 killer T-cells from allogeneic iPS cells. This review discusses the induction of CD8 killer T-cells from iPS cells, efforts to improve the safety and certainty of the induction process for clinical use, and the utility of gene editing to reduce allogeneic antigenicity of iPS T-cells.

Abstract
The efficacy of T-cell therapy depends on the maintenance of antigen specificity, memory phenotype, longterm viability, and proliferative capacity of T cells in vivo. Personalized autologous T-cell therapies pose a few manufacturing challenges, in terms of quality, and supply stability. Recently, it has become possible to derive CD8 killer T cells from induced pluripotent stem cells (iPSCs) and develop CAR-CD8 killer T cells from allogeneic iPSCs. This article reviews CD8 killer T-cell induction from iPSCs, attempts to enhance process safety and reliability, and discusses the use of gene-editing technology for reducing allogeneic antigenicity.

Abstract
Tumor-infiltrating lymphocytes (TIL), which include tumor-specific T lymphocytes with frequency, are used for adoptive cell transfer therapy (ACT) in clinical practice. The optimization of TIL preparation has been investigated to reduce the senescence and increase the abundance of TIL, as both the quality and quantity of the transferred cells have great influence on the outcome of TIL-based ACT (TIL-ACT). Considering the effects of cell reprogramming on senescence, we expected that the anti-tumor effect could be enhanced by TIL regeneration. To confirm this hypothesis, we established tumor-specific TIL-derived iPS cells (TIL-iPSC) with human colorectal cancer specimens. T cells differentiated from TIL-iPSC (TIL-iPS-T) retained not only intrinsic T cell functions and tumor specificity, but also exhibited improved proliferation capacity and additional killing activity. Moreover, less differentiated profiles and prolonged persistency were seen in TIL-iPS-T compared with primary cells. Our findings imply that iPSC technology has great potential for TIL-ACT.

Abstract
Trophoblasts are extraembryonic cells that are essential for maintaining pregnancy. Human trophoblasts arise from the morula as trophectoderm (TE), which, after implantation, differentiates into cytotrophoblasts (CTs), syncytiotrophoblasts (STs), and extravillous trophoblasts (EVTs), composing the placenta. Here we show that naïve, but not primed, human pluripotent stem cells (PSCs) recapitulate trophoblast development. Naive PSC-derived TE and CTs (nCTs) recreated human and monkey TE-to-CT transition. nCTs self-renewed as CT stem cells and had the characteristics of proliferating villous CTs and CTs in the cell column of the first trimester. Notably, although primed PSCs differentiated into trophoblast-like cells (BMP4, A83-01, and PD173074 [BAP]-treated primed PSCs [pBAPs]), pBAPs were distinct from nCTs and human placenta-derived CT stem cells, exhibiting properties consistent with the amnion. Our findings establish an authentic paradigm for human trophoblast development, demonstrating the invaluable properties of naive human PSCs. Our system provides a platform to study the molecular mechanisms underlying trophoblast development and related diseases.

Abstract
Because of their close biological similarity to humans, non-human primate (NHP) models are very useful for the development of induced pluripotent stem cell (iPSC)-based cell and regenerative organ transplantation therapies. However, knowledge on the establishment, differentiation, and genetic modification of NHP-iPSCs, especially rhesus macaque iPSCs, is limited. We succeeded in establishing iPSCs from the peripheral blood of rhesus macaques (Rh-iPSCs) by combining the Yamanaka reprograming factors and two inhibitors (GSK-3 inhibitor [CHIR 99021] and MEK1/2 inhibitor [PD0325901]) and differentiated the cells into functional macrophages through hematopoietic progenitor cells. To confirm feasibility of the Rh-iPSC-derived macrophages as a platform for bioassays to model diseases, we knocked out TRIM5 gene in Rh-iPSCs by CRISPR-Cas9, which is a species-specific HIV resistance factor. TRIM5 knockout (KO) iPSCs had the same differentiation potential to macrophages as did Rh-iPSCs, but the differentiated macrophages showed a gain of sensitivity to HIV infection in vitro. Our reprogramming, gene editing, and differentiation protocols used to obtain Rh-iPSC-derived macrophages can be applied to other gene mutations, expanding the number of NHP gene therapy models.

Abstract
The tumorigenicity and toxicity of induced pluripotent stem cells (iPSCs) and their derivatives are major safety concerns in their clinical application. Recently, we developed granulocyte-macrophage colony-stimulating factor (GM-CSF)-producing proliferating myeloid cells (GM-pMCs) from mouse iPSCs as a source of unlimited antigen-presenting cells for use in cancer immunotherapy. As GM-pMCs are generated by introducing c-Myc and Csf2 into iPSC-derived MCs and are dependent on self-produced GM-CSF for proliferation, methods to control their proliferation after administration should be introduced to improve safety. In this study, we compared the efficacy of two promising suicide gene systems, herpes simplex virus-thymidine kinase (HSV-TK)/ganciclovir (GCV) and inducible caspase-9 (iCasp9)/AP1903, for safeguarding GM-pMCs in cancer immunotherapy. The expression of HSV-TK or iCasp9 did not impair the fundamental properties of GM-pMCs. Both of these suicide gene-expressing cells selectively underwent apoptosis after treatment with the corresponding apoptosis-inducing drug, and they were promptly eliminated in vivo. iCasp9/AP1903 induced apoptosis more efficiently than HSV-TK/GCV. Furthermore, high concentrations of GCV were toxic to cells not expressing HSV-TK, whereas AP1903 was bioinert. These results suggest that iCasp9/AP1903 is superior to HSV-TK/GCV in terms of both safety and efficacy when controlling the fate of GM-pMCs after priming antitumor immunity.

Abstract
Genetic engineering of induced pluripotent stem cells (iPSCs) holds great promise for gene and cell therapy as well as drug discovery. However, there are potential concerns regarding the safety and control of gene expression using conventional vectors such as viruses and plasmids. Although human artificial chromosome (HAC) vectors have several advantages as a gene delivery vector, including stable episomal maintenance and the ability to carry large gene inserts, the full potential of HAC transfer into iPSCs still needs to be explored. Here, we provide evidence of a HAC transfer into human iPSCs by microcell-mediated chromosome transfer via measles virus envelope proteins for various applications, including gene and cell therapy, establishment of versatile human iPSCs capable of gene loading and differentiation into T cells, and disease modeling for aneuploidy syndrome. Thus, engineering of human iPSCs via desired HAC vectors is expected to be widely applied in biomedical research.

Abstract
Tumorigenicity of induced pluripotent stem cells (iPSCs) is anticipated when cells derived from iPSCs are transplanted. It has been reported that iPSCs formed a teratoma in vivo in autologous transplantation in a nonhuman primate model without immunosuppression. However, there has been no study on tumorigenicity in major histocompatibility complex (MHC)-matched allogeneic iPSC transplantation with immune-competent hosts. To examine the tumorigenicity of allogeneic iPSCs, we generated four iPSC clones carrying a homozygous haplotype of the MHC. Two clones were derived from female fibroblasts by using a retrovirus and the other two clones were derived from male peripheral blood mononuclear cells by using Sendai virus (episomal approach). The iPSC clones were transplanted into allogenic MHC-matched immune-competent cynomolgus macaques. After transplantation of the iPSCs into subcutaneous tissue of an MHC-matched female macaque and into four testes of two MHC-matched male macaques, histological analysis showed no tumor, inflammation, or regenerative change in the excised tissues 3 months after transplantation, despite the results that iPSCs formed teratomas in immune-deficient mice and in autologous transplantation as previously reported. The results in the present study suggest that there is no tumorigenicity of iPSCs in MHC-matched allogeneic transplantation in clinical application.

Abstract
The field-induced superconductor-insulator transition (SIT) in two-dimensional (2D) systems is a famous example of a quantum phase transition. However, an emergence of an anomalous metallic state induced by field has been a long-standing problem in 2D superconductors. While theories predicted that the emergence is attributed to strong phase fluctuations of the superconducting order parameter due to quantum fluctuations, usual resistance measurements have not probed them directly. Here, using Nernst effect measurements, we uncover superconducting fluctuations in the vicinity of the field-induced metallic state in an amorphous Mo_{x}Ge_{1-x} thin film. The field range where the vortex Nernst signals are detectable remains nonzero toward zero temperature, and it locates inside the metallic state defined by the magnetoresistance, indicating that the metallic state results from quantum vortex liquid (QVL) with phase fluctuations due to quantum fluctuations. Slow decay of transport entropy of vortices in the QVL with decreasing temperature suggests that the metallic state originates from broadening of a quantum critical point in SIT.

Abstract
In 2007, Human-induced pluripotent stem cells (iPSCs) were generated by transducing four genes (Oct3/4, Sox2, Klf4, c-Myc). Because iPSCs can differentiate into any types of cells in the body and have fewer ethical issues compared to embryonic stem (ES) cells, application of iPSCs for regenerative medicine has been actively examined. In fact, iPSCs have already been used for clinical applications, but at present, only autologous iPSC-derived grafts or HLA homozygous iPSC-derived grafts are being transplanted into patients following HLA matching. HLA is an important molecule that enables the immune system differentiates between self and non-self-components; thus, HLA mismatch is a major hurdle in the transplantation of iPSCs. To deliver inexpensive off-the-shelf iPSC-derived regenerative medicine products to more patients, it is necessary to generate universal iPSCs that can be transplanted regardless of the HLA haplotypes. The current strategy to generate universal iPSCs has two broad aims: deleting HLA expression and avoiding attacks from NK cells, which are caused by HLA deletion. Deletion of B2M and CIITA genes using the CRISPR/Cas9 system has been reported to suppress the expression of HLA class I and class II, respectively. Transduction of NK inhibitory ligands, such as HLA-E and CD47, has been used to avoid NK cell attacks. Most recently, the HLA-C retaining method has been used to generate semi-universal iPSCs. Twelve haplotypes of HLA-C retaining iPSCs can cover 95% of the global population. In future, studying which types of universal iPSCs are most effective for engraftment in various physiological conditions is necessary.

Abstract
Type I interferons (IFNs) play important roles in antitumor immunity. We generated IFN-α-producing cells by genetically engineered induced pluripotent stem cell (iPSC)-derived proliferating myeloid cells (iPSC-pMCs). Local administration of IFN-α-producing iPSC-pMCs (IFN-α-iPSC-pMCs) alters the tumor microenvironment and propagates the molecular signature associated with type I IFN. The gene-modified cell actively influences host XCR1+ dendritic cells to enhance CD8+ T cell priming, resulting in CXCR3-dependent and STING-IRF3 pathway-independent systemic tumor control. Administration of IFN-α-iPSC-pMCs in combination with immune checkpoint blockade overcomes resistance to single-treatment modalities and generates long-lasting antitumor immunity. These preclinical data suggest that IFN-α-iPSC-pMCs might constitute effective immune-stimulating agents for cancer that are refractory to checkpoint blockade.

Abstract
Immunotherapy using dendritic cells (DCs) is a promising treatment modality for cancer. However, the limited number of functional DCs from peripheral blood has been linked to the unsatisfactory clinical efficacies of current DC-based cancer immunotherapies. We previously generated proliferating antigen-presenting cells (APCs) by genetically engineering myeloid cells derived from induced pluripotent stem cells (iPSC-pMCs), which offer infinite functional APCs for broad applications in cancer therapy. Herein, we aimed to further enhance the antitumor effect of these cells by genetic modification. GM-CSF gene transfer did not affect the morphology, or surface phenotype of the original iPSC-pMCs, however, it did impart good viability to iPSC-pMCs. The resultant cells induced GM-CSF-dependent CD8+ T cell homeostatic proliferation, thereby enhancing antigen-specific T cell priming in vitro. Administration of the tumor antigen-loaded GM-CSF-producing iPSC-pMCs (GM-pMCs) efficiently stimulated antigen-specific T cells and promoted effector cell infiltration of the tumor tissues, leading to an augmented antitumor effect. To address the potential tumorigenicity of iPSC-derived products, irradiation was applied and found to restrict the proliferation of GM-pMCs, while retaining their T cell-stimulatory capacity. Furthermore, the irradiated cells exerted an antitumor effect equivalent to that of bone marrow-derived DCs obtained from immunocompetent mice. Additionally, combination with immune checkpoint inhibitors increased the infiltration of CD8+ or NK1.1+ effector cells and decreased CD11b+/Gr-1+ cells without causing adverse effects. Hence, although GM-pMCs have certain characteristics that differ from endogenous DCs, our findings suggest the applicability of these cells for broad clinical use and will provide an unlimited source of APCs with uniform quality.

Abstract
Precision medicine is an emerging approach for disease treatment and prevention that accounts for individual variability in genes, environment, and lifestyle. Cancer is a genomic disease; therefore, the dose-efficacy and dose-toxicity relationships for molecularly targeted agents in cancer most likely differ, based on the genomic mutation pattern. The individualized optimal dose - the maximal efficacious dose with a clinically acceptable safety profile - may vary depending on the genomic mutation patterns and should be determined prior to the use of these agents in precision medicine. In addition, genes that influence the individualized optimal doses should be identified in early-phase development. In this study, we propose a novel dose-finding approach to identify the individualized optimal dose for molecularly targeted agents in phase I cancer trials. Individualized optimal dose determination and gene selection were conducted simultaneously based on L 1 and L 2 penalized regression. Similar to most reported dose-finding approaches, this study considers non-monotonic patterns for dose-efficacy and dose-toxicity relationships, as well as correlations between efficacy and toxicity outcomes based on multinomial distribution. Our dose-finding algorithm is based on the predictive probability calculated with an estimated penalized regression model. We compare the operating characteristics between the proposed and existing methods by simulation studies under various scenarios.

Abstract
We investigated the change in the metal-molecule interaction in a 1,4-benzenedithiol (BDT) single-molecule junction using a combination of surface-enhanced Raman scattering spectra and current-voltage curves. During the stretching process, the conductance of the junction systematically decreased, accompanied by an increase in the vibrational energy of the CC stretching mode. By analyzing the current-voltage curves and Raman spectra, we found that the interaction between the π orbital of BDT and the electronic states of Au was diminished by the orientation change of BDT during the stretching process. A comparison with a 4,4'-bipyridine single-molecule junction revealed that the reduction of coupling of the Au-S contacts was smaller than that of Au-pyridine contacts. Therefore, the electronic states originating from the contact geometry are responsible for the tolerance to the stretching of thiol-terminated molecular junctions.

Abstract
The distinct lineage potential is a key feature of hematopoietic stem cell (HSC) heterogeneity, but a subset of HSCs specialized for a single lymphoid compartment has not been identified. Here we report that HSCs expressing junctional adhesion molecule 2 (Jam2) at a higher level (Jam2high HSCs) have a greater T cell reconstitution capacity. Jam2high HSCs are metabolically dormant but preferentially differentiate toward lymphocytes, especially T cell lineages. Jam2high HSCs uniquely express T cell-related genes, and the interaction with Jam1 facilitates the Notch/Delta signaling pathway. Frequency of Jam2high HSCs changes upon T cell depletion in vivo, potentially suggesting that Jam2 expression may reflect scarcity of T cells and requirement of T cell replenishment. Our findings highlight Jam2 as a potential marker for a subfraction of HSCs with an extensive lymphopoietic capacity, mainly in T lymphopoiesis.

Abstract
The use of allogeneic, pluripotent stem‐cell‐derived immune cells for cancer immunotherapy has been the subject of recent clinical trials. In Japan, investigator‐initiated clinical trials will soon begin for ovarian cancer treatment using human leukocyte antigen (HLA)‐homozygous‐induced pluripotent stem cell (iPSC)‐derived anti–glypican‐3 (GPC3) chimeric antigen receptor (CAR)‐expressing natural killer/innate lymphoid cells (NK/ILC). Using pluripotent stem cells as the source for allogeneic immune cells facilitates stringent quality control of the final product, in terms of efficacy, safety and producibility. In this paper, we describe our methods for the stable, feeder‐free production of CAR‐expressing NK/ILC cells from CAR‐transduced iPSC with clinically relevant scale and materials. The average number of cells that could be differentiated from 1.8‐3.6 × 106 iPSC within 7 weeks was 1.8‐4.0 × 109. These cells showed stable CD45/CD7/CAR expression, effector functions of cytotoxicity and interferon gamma (IFN‐γ) production against GPC3‐expressing tumor cells. When the CAR‐NK/ILC cells were injected into a GPC3‐positive, ovarian‐tumor‐bearing, immunodeficient mouse model, we observed a significant therapeutic effect that prolonged the survival of the animals. When the cells were injected into immunodeficient mice during non–clinical safety tests, no acute systemic toxicity or tumorigenicity of the final product or residual iPSC was observed. In addition, our test results for the CAR‐NK/ILC cells generated with clinical manufacturing standards are encouraging, and these methods should accelerate the development of allogeneic pluripotent stem cell‐based immune cell cancer therapies.

Abstract
Abstract
Background
Long QT syndrome type 8 (LQT8) caused by mutations in CACNA1C has been classified as a very rare and severe type of long QT syndrome accompanied with Timothy syndrome (TS) with extra-cardiac phenotype. Recently, various mutations in CACNA1C have been identified in non-TS patients. However, mutation specific severity in LQT8 has not been elucidated yet, especially for non-TS patients.
Purpose
We aimed to clarify the clinical characteristics of LQT8 patients.
Methods
The study consists of 26 LQT8 patients (21 probands and 5 family members). We evaluated their phenotype.
Results
Table summarizes the clinical characteristics of LQT8 patients. TS patients diagnosed in younger age than those of non-TS. Four TS and one non-TS patients were diagnosed at the age of 0, though the non-TS patient was a son of a patient and asymptomatic. Nine patients suffered symptoms including 7 with cardiac arrest. We identified three TS mutations; classical p.G406R in two and p.G402S in two, and a new TS mutation, p.412M in one. Four of TS patients were symptomatic and two died suddenly at the age of 4 and 5. In contrast, no one died in non-TS patients. Five non-TS patients suffered symptoms in the age of 4,9,15,54 and 64, and the mutations were p.S643F, p.R858H (2 patients), p.K1518E and p.K1591T.
Characteristics of TS and non-TS patient TS Non-TS P N (male) 5 (2) 21 (9) Age (range) 0 (0–7) 12 (0–64) 0.004 Symptom Syncope 4 5 0.034 CPA 3 4 0.101 ECG characteristics QT interval 603±40 507±14 0.011 T wave alternans 5 2 <0.001 AV Block 4 1 0.002 Therapy (4 unknown) Beta-blocker 4 7 0.311 Mexiletine 3 1 0.024 ICD implantation 2 2 0.21
Conclusions
Although TS patients showed severe phenotype, most of the non-TS patients were asymptomatic. The phenotype in LQT8 are diversely different depend on the mutations, especially between patients with TS and non-TS.

Abstract
Abstract
Background
One disadvantage of hot balloon ablation (HBA) system is that real time monitoring of pulmonary vein (PV) potential is technically impossible. Therefore, the optimal radiofrequency-generated thermal energy application duration and application number are not completely established.
Purpose
The aim of this study is to evaluate the utility of 2Fr 4-electrode unidirectional catheter inserted into PV along with HB for real time monitoring of PV potential and investigate the time to isolation (TTI) guided optimal application strategy for HB based PV isolation in the acute phase.
Methods
We evaluated 23 consecutive patients who performed PV isolation using HBA system. Real time monitoring of PV potential was performed by 2Fr 4-electrode unidirectional catheter inserted into PV along with HB (Figure1A). After HBA applications, PV isolation was validated by high-resolution mapping with the 20-pole steerable mapping (PENTARAY) catheter as a standard. PV potentials during HBA application were categorized into five patterns. PV potentials disappeared during HBA applications and not emerged again (acute isolation), disappeared but verified by PENTARAY catheter (pseudo isolation), once disappeared but emerged again during the same application (acute reconnection), visible but not disappeared (ineffective application) and Invisible (Figure1B).
TTI, difference between TTI and time to reach target temperature (TTRT), balloon temperature at isolation and ablation time after isolation were examined for each applications.
Results
Out of 92 PVs, 69/92 (75.0%) PVs were isolated using HBA and 23/92 (25.0%) PVs required touch up ablation. In total, 120 applications were performed. Real time monitoring of the PV activity was obtained in 114 of 120 applications (95.0%). The distribution of PV potential patterns were 64/120 (53.3%), 2/120 (1.7%), 27/120 (22.5%), 23/120 (19.2%), for acute isolation, pseudo isolation, acute reconnection, ineffective application, respectively.
TTI and difference between TTI and TTRT were significantly shorter in the acute isolation group. Balloon temperature at isolation was significantly lower, TTRT and ablation time after isolation was significantly longer in the acute isolation group. Among them, TTI and difference between TTI and TTRT were highly predictive by receiver operation characteristics curve analysis. TTI <36.5s predicted successful application with sensitivity 83.9% and specificity 79.3%. Difference between TTI and TTRT <6.5s predicted with sensitivity 82.3% and specificity 89.7%.
Figure 1
Conclusions
In HBA system, real time monitoring of PV potentials can be obtained using 2Fr 4-electrode unidirectional catheter and accuracy to confirm an ostial PV isolation is relatively high.
TTI <36.5s and difference between TTI and TTRT <6.5s could be a suitable target for effective application.

Abstract
Abstract
Background
Hepatokine selenoprotein P (SeP) contributes to insulin resistance and hyperglycemia in patients with type 2 diabetes. Inhibition of SeP protects the heart from ischemia reperfusion injury and serum levels of SeP are elevated in patients with heart failure with reduced ejection fraction.
Objective
We investigated the role of SeP in the regulation of cardiac remodeling in response to pressure overload.
Methods and results
To examine the role of SeP in cardiac remodeling, transverse aortic constriction (TAC) was subjected to SeP knockout (KO) and wild-type (WT) mice for 2 weeks. Hepatic expression of SeP in WT was significantly increased by TAC. LV weight/tibial length (TL) was significantly smaller in SeP KO mice than in WT mice (6.75±0.24 vs 8.33±0.32, p<0.01). Lung weight/TL was significantly smaller in SeP KO than in WT mice (10.46±0.44 vs 16.38±1.12, p<0.05). TAC-induced cardiac upregulation of the fetal type genes, including atrial and brain natriuretic factors, was significantly attenuated in SeP KO compared to WT. Furthermore, azan staining revealed that there was significantly less interstitial fibrosis in hearts after TAC in SeP KO than in WT mice. To determine whether hepatic overexpression of SeP affects TAC-induced cardiac hypertrophy, a hydrodynamic injection method was used to generate mice that overexpress SeP mRNA in the liver. Hepatic overexpression of SeP in SeP KO mice lead to a significant increase in LV weight/TL and Lung weight/TL after TAC compared to that in other SeP KO mice.
Conclusions
These results suggest that cardiac pressure overload induced hepatic expression of SeP and the absence of endogenous SeP attenuated cardiac hypertrophy, dysfunction and fibrosis in response to pressure overload in mice. SeP possibly plays a maladaptive role against progression of heart failure through the liver-heart axis.

Abstract
The atomic switches have attracted wide attention owing to their applications in nonvolatile electric devices. The atomic switch is operated by the formation and dissipation of a metallic filament inside a metal sulfide film, which is controlled by a solid electrochemical reaction. Although the metallic filament is considered to consist of metal atoms, the chemical species of the metallic filament are difficult to be identified due to challenges in observing the metallic filament inside the solid. In this study, we report the investigation on the metallic filament in the atomic switch with metal sulfide based on point-contact spectroscopy (PCS). By cooling the atomic switch, the switch voltage increased to 1 V, which allowed for the PCS measurement. The PCS revealed that the metallic filament was composed of Ag atoms in the case of the Pt/Ag2S/Ag atomic switch. We applied this technique to the Pt/Cu2S/Ag and Pt/Ag2S/Cu atomic switches to uncover the formation process of the metallic filament. In both atomic switches, the chemical species of the metallic filament were Ag. The metal atoms were supplied from both the metal electrode and the sulfide layer.

Abstract
Abstract
Chimeric antigen receptor (CAR) is an artificial protein that provides HLA-independent antigen specificity to T cells. CAR-T therapy has shown remarkable clinical responses especially in hematologic malignancies. But this therapy requires cell preparation for each patient and it cause some limitations for applicability of CAR-T therapy. We have reported regeneration of T cells from iPSCs (Cell Stem Cell. 2013). Since this technology can provide unlimited number of T cells, CAR-T therapy using iPSCs is thought to broaden its applicability. To target solid tumors, it is important to avoid immunosuppressive factors from tumor microenvironment and to exert sufficient cytotoxicity. Tumor reactive T cells are known to fall into anergy state by continuous antigen stimulations. To overcome immunosuppression in tumor microenvironment, enhancement of TCR signaling by modification of genes related to TCR signal is a promising strategy. Recent studies revealed that the efficacy of CAR-iPS-T cells are not equivalent to primary CAR-T cells. To enhance the efficacy of CAR-iPS-T cells and to produce resistant CAR-T cells to immunosuppression, we focused on TCR signaling pathway. We found that antigen reactivity of CAR-iPS-T cells was insufficient compared with primary CAR-T cells. To overcome the weakness of TCR signal, we disrupted genes negatively related to TCR signal and successfully enhanced TCR signal. As a result, genome edited CAR-iPS-T cells could persist longer in vivo and displayed enhanced tumor suppressive function comparable with primary CAR-T cells. Genome edited iPSCs can be a unlimited cell source of enhanced CAR-T cells. These findings indicate that regenerated CAR-T cells derived from genome edited iPSCs would be a promising CAR-T therapy which would overcome immunosuppressive tumor microenvironment.

Abstract
OBJECTIVES Stunting is a significant cause of poor cognitive performance and lower school achievement. Stunting is observed among pre-school children in several areas in Africa; however, not all children are affected, and children with and without stunting are seen in the same communities. Therefore, this study aimed to identify nutritional and other factors that prevent stunting that may exist in local communities. STUDY DESIGN This is a prospective cohort study. METHODS Data were extracted from the Health and Demographic Surveillance System conducted in Kwale County, Kenya. The cohort consisted of all households with children less than five years old, within a radius of 2.2 km from a local health centre. A dietary pattern (DP) survey with a semi-quantitative food frequency questionnaire was conducted on caretakers of children who were voluntary participated from the cohort between June 2012 and August 2012. Using cluster analysis, the children were assigned to a DP group. Logistic regression analysis was applied to calculate the adjusted odds ratios (aORs) of DPs for stunting controlling for other factors. RESULTS In total, 402 children were included in the analysis. By cluster analysis, three DPs were identified: protein-rich DP; traditional DP; and traditional DP complemented by breastfeeding. The aOR of a child becoming stunted from a normal height during the study period among children who received a traditional DP compared with those who had a protein-rich DP was 2.78 (95% confidence interval [CI]: 1.02-7.55). However, the aOR for children who were already stunted at the start of the study and had a traditional DP was 1.49 (95% CI: 0.82-2.72). Increased aORs of stunting were observed among children aged over 12 months compared with children aged 6-11 months, and the effects of DPs were modified by age in months from 12 to 35 months; however, the effects were near the null value for children over 36 months of age, although these were not statistically significant. CONCLUSIONS We found that the traditional DP showed a higher risk for stunting compared with the protein-rich DP, and the most vulnerable age range for stunting was between 12 and 35 months. Interventions to prevent stunting should focus on providing 12- to 35-month-old children with locally available, protein-rich foods.

Abstract
We have studied the formation process of the metal atomic filament for metal sulfide atomic switches by electrical measurement. The switching between ON and OFF states of the atomic switch is controlled by the application of the bias voltage for the atomic switches. The SET (OFF → ON) and RESET (ON → OFF) voltages were investigated for the atomic switch where the Ag2S or Cu2S layer were sandwiched between the Pt and Ag or Cu electrodes. The SET and RESET voltages of the Ag/Cu2S/Pt and Cu/Ag2S/Pt were close to those of the Ag/Ag2S/Pt atomic switch, and different from those of the Cu/Cu2S/Pt atomic switch. These results indicated that the dominant chemical species of the making and breaking part of the metal filament was Ag, and that the source of the metal filament was both the sulfide layer and the metal electrode.

Abstract
Induced pluripotent stem cells (iPSCs) have strong potential in regenerative medicine applications; however, immune rejection caused by HLA mismatching is a concern. B2M gene knockout and HLA-homozygous iPSC stocks can address this issue, but the former approach may induce NK cell activity and fail to present antigens, and it is challenging to recruit rare donors for the latter method. Here, we show two genome-editing strategies for making immunocompatible donor iPSCs. First, we generated HLA pseudo-homozygous iPSCs with allele-specific editing of HLA heterozygous iPSCs. Second, we generated HLA-C-retained iPSCs by disrupting both HLA-A and -B alleles to suppress the NK cell response while maintaining antigen presentation. HLA-C-retained iPSCs could evade T cells and NK cells in vitro and in vivo. We estimated that 12 lines of HLA-C-retained iPSCs combined with HLA-class II knockout are immunologically compatible with >90% of the world's population, greatly facilitating iPSC-based regenerative medicine applications.

Abstract
In order to differentiate T cells in vitro, co-culture systems with Notch ligand-expressing feeder cells have been in use for a long time. Here we describe a feeder-free culture condition for differentiating T cells from hematopoietic cells that are cultured on Fc-DLL4-coated plate with T-lineage cytokines. This condition is capable of efficiently differentiating hematopoietic progenitor cells (HPCs) to immature T cells expressing both CD4 and CD8. To mature those cells into functional T cells, further stimulation and culture is necessary.

Abstract
In this chapter, we describe a protocol for hematopoietic differentiation of nonhuman primate (NHP)-induced pluripotent stem cells (iPSCs) derived from T cells and generation of T cells. Derivation of T cells from PSCs involves three steps: induction of PSCs to hematopoietic progenitor cells (HPCs), differentiation of HPCs into progenitor T cells, and maturation of progenitor T cells into mature T cells, in particular CD8 single-positive (SP) T cells.

Abstract
Recent outstanding clinical results produced by engineered T cells, including chimeric antigen receptors, have already facilitated further research that broadens their applicability. One such direction is to explore new T cell sources for allogeneic “off‐the‐shelf” adoptive immunotherapy. Human pluripotent stem cells could serve as an alternative cell source for this purpose due to their unique features of infinite propagation ability and pluripotency. Here, we describe the current state of engineered T cell transfer with the focus on cell manufacturing processes and the potentials and challenges of induced pluripotent stem cell‐derived T cells as a starting material to construct off‐the‐shelf T‐cell banks.

Abstract
T cells engineered to express chimeric antigen receptor (CAR) against the B cell antigen CD19 are achieving remarkable clinical effects on hematological malignancies. Allogeneic transplantation approach is promising for broaden application of CART therapy. iPSCs are one of the ideal cell sources for this approach. CAR-engineered iPSCs are demonstrated to give rise to CAR-engineered T cell and exert their effector function. In this section, we describe the method to generate CAR-engineered iPSCs and differentiate them into T cells.
