Abstract
The world's first clinical cardiac xenotransplantation, using a genetically engineered pig heart with 10 gene modifications, prolonged the life of a 57-year-old man with no other life-saving options, by 60 days. It is foreseeable that xenotransplantation will be introduced in clinical practice in the United States. However, little clinical or regulatory progress has been made in the field of xenotransplantation in Japan in recent years. Japan seems to be heading toward a "device lag", and the over-importation of medical devices and technology in the medical field is becoming problematic. In this review, we discuss the concept of pig-heart xenotransplantation, including the pathobiological aspects related to immune rejection, coagulation dysregulation, and detrimental heart overgrowth, as well as genetic modification strategies in pigs to prevent or minimize these problems. Moreover, we summarize the necessity for and current status of xenotransplantation worldwide, and future prospects in Japan, with the aim of initiating xenotransplantation in Japan using genetically modified pigs without a global delay. It is imperative that this study prompts the initiation of preclinical xenotransplantation research using non-human primates and leads to clinical studies.

Abstract
OBJECTIVE Innate immunity plays a vital role in xenotransplantation. A CD47 molecule, binding to the SIRPα expressed on monocyte/macrophage cells, can suppress cytotoxicity. Particularly, the SIRPα contains ITIM, which delivers a negative signal. Our previous study demonstrated that the binding between CL-P1 and surfactant protein-D hybrid (CL-SP-D) with SIRPα regulates macrophages' phagocytic activity. In this study, we examined the effects of human CD47 and CL-SP-D expression on the inhibition of xenograft rejection by neutrophils in swine endothelial cells (SECs). METHODS We first examined SIRPα expression on HL-60 cells, a neutrophil-like cell line, and neutrophils isolated from peripheral blood. CD47-expressing SECs or CL-SP-D-expressing SECs were generated through plasmid transfection. Subsequently, these SECs were co-cultured with HL-60 cells or neutrophils. After co-culture, the degree of cytotoxicity was calculated using the WST-8 assay. The suppressive function of CL-SP-D on neutrophils was subsequently examined, and the results were compared with those of CD47 using naïve SECs as controls. Additionally, we assessed ROS production and neutrophil NETosis. RESULTS In initial experiments, the expression of SIRPα on HL-60 and neutrophils was confirmed. Exposure to CL-SP-D significantly suppressed the cytotoxicity in HL-60 (p = 0.0038) and neutrophils (p = 0.00003). Furthermore, engagement with CD47 showed a suppressive effect on neutrophils obtained from peripheral blood (p = 0.0236) but not on HL-60 (p = 0.4244). The results of the ROS assays also indicated a significant downregulation of SEC by CD47 (p = 0.0077) or CL-SP-D (p = 0.0018). Additionally, the suppression of NETosis was confirmed (p = 0.0125) in neutrophils co-cultured with S/CL-SP-D. CONCLUSION These results indicate that CL-SP-D is highly effective on neutrophils in xenogeneic rejection. Furthermore, CL-SP-D was more effective than CD47 at inhibiting neutrophil-mediated xenograft rejection.

Abstract
Extracorporeal photochemotherapy (ECP) is one of the more effective cell therapies for graft-versus-host disease (GvHD). ECP is a widely recommended therapeutic approach for the treatment of chronic GvHD, particularly steroid-refractory GVHD. In recent years, the use of a light emitting diode (LED) in the clinic has attracted considerable interest. In this study, we examined the issue of whether an ultraviolet A1-light emitting diode (UVA1-LED) can be used as a light source in ECP. To compare the efficacy of ECP with conventional UVA lamp and a UVA1-LED, we established an in vitro ECP model. Treatment efficacy was evaluated by measuring the % apoptosis and the inhibition of T-cell proliferation. To investigate the effect of ECP on the innate immune reaction, THP-1 cells with a luciferase reporter gene driven by a NF-kB response element (THP-1 luc NF-kB) were treated with ECP. The LED-ECP induced apoptosis and inhibition of T-cell proliferation as efficiently as a conventional ECP. However, LED-ECP induced less innate immunity in THP-1. Since LED devices are more compact compared with conventional UVA irradiation devices, the use of a UVA1-LED in the treatment of ECP may be a better alternative to conventional ECP therapy.

Abstract
Cellular xenogeneic rejection by the innate immune system is a major immunological obstruction that needs to be overcome for the successful clinical use of xenografts. Our focus has been on macrophage-mediated xenogeneic rejection, since suppressing macrophage function has considerable potential for practical applications in the area of xenotransplantation. We report herein on an investigation of the suppressive effect of human CD177 (hCD177) against macrophage-mediated xenogeneic rejection. Wild type swine aortic endothelial cell (SEC) and an SEC transfectant with hCD177 (SEC/hCD177) were co-cultured with macrophages, and the degree of cytotoxicity was evaluated by WST-8 assays, and phagocytosis was examined using Calcein-AM labeling methods. The expression of anti/pro-inflammatory cytokines was evaluated by RT-qPCR and the phosphorylation of SHP-1 on macrophages in co-culture was evaluated by Western blotting. The result of cytotoxicity assays indicated that hCD177 suppressed M1 macrophage-mediated xenogeneic rejection (vs. SEC, p < 0.0001). Similarly, the result of phagocytosis assays indicated that hCD177 suppressed it (vs. SEC, p < 0.05). In addition, hCD177 significantly suppressed the expression of IL-1β, a pro-inflammatory cytokine, in M1 macrophages (vs. SEC, p < 0.01). Luciferase assays using THP1-Lucia NF-kB also showed a significant difference in NF-kB activation (vs. SEC, p < 0.001). In addition, hCD177 was found to induce the phosphorylation of SHP-1 in M1 macrophages (vs. SEC, p < 0.05). These findings indicate that hCD177 suppresses M1 macrophage-mediated xenogeneic rejection, at least in part via in the phosphorylation of SHP-1.

Abstract
Xenotransplantation is very attractive strategy for addressing the shortage of donors. While hyper acute rejection (HAR) caused by natural antibodies and complement has been well defined, this is not the case for innate cellular xenogeneic rejection. An increasing body of evidence suggests that innate cellular immune responses contribute to xenogeneic rejection. Various molecular incompatibilities between receptors and their ligands across different species typically have an impact on graft outcome. NK cells are activated by direct interaction as well as by antigen dependent cellular cytotoxicity (ADCC) mechanisms. Macrophages are activated through various mechanisms in xenogeneic conditions. Macrophages recognize CD47 as a "marker of self" through binding to SIRPα. A number of studies have shown that incompatibility of porcine CD47 against human SIRPα contributes to the rejection of xenogeneic target cells by macrophages. Neutrophils are an early responder cell that infiltrates xenogeneic grafts. It has also been reported that neutrophil extracellular traps (NETs) activate macrophages as damage-associated pattern molecules (DAMPs). In this review, we summarize recent insights into innate cellular xenogeneic rejection.

Abstract
After producing triple (Gal, H-D and Sda)-KO pigs, hyperacute rejection appeared to no longer be a problem. However, the origin of xeno-rejection continues to be a controversial topic, including small amounts of antibodies and subsequent activation of the graft endothelium, the complement recognition system and the coagulation systems. The complement is activated via the classical pathway by non-Gal/H-D/Sda antigens and by ischemia-reperfusion injury (IRI), via the alternative pathway, especially on islets, and via the lectin pathway. The complement system therefore is still an important recognition and effector mechanism in xeno-rejection. All complement regulatory proteins (CRPs) regulate complement activation in different manners. Therefore, to effectively protect xenografts against xeno-rejection, it would appear reasonable to employ not only one but several CRPs including anti-complement drugs. The further assessment of antigens continues to be an important issue in the area of clinical xenotransplantation. The above conclusions suggest that the expression of sufficient levels of human CRPs on Triple-KO grafts is necessary. Moreover, multilateral inhibition on local complement activation in the graft, together with the control of signals between macrophages and lymphocytes is required.

Abstract
Background Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of genetic autosomal recessive diseases that cause severe cholestasis, which progresses to cirrhosis and liver failure, in infancy or early childhood. We herein report the clinical outcomes of surgical management in patients with four types of PFIC. Case presentation Six patients diagnosed with PFIC who underwent surgical treatment between 1998 and 2020 at our institution were retrospectively assessed. Living-donor liver transplantation (LDLT) was performed in 5 patients with PFIC. The median age at LDLT was 4.8 (range: 1.9–11.4) years. One patient each with familial intrahepatic cholestasis 1 (FIC1) deficiency and bile salt export pump (BSEP) deficiency died after LDLT, and the four remaining patients, one each with deficiency of FIC1, BSEP, multidrug resistance protein 3 (MDR3), and tight junction protein 2 (TJP2), survived. One FIC1 deficiency recipient underwent LDLT secondary to deterioration of liver function, following infectious enteritis. Although he underwent LDLT accompanied by total external biliary diversion, the patient died because of PFIC-related complications. The other patient with FIC1 deficiency had intractable pruritus and underwent partial internal biliary diversion (PIBD) at 9.8 years of age, pruritus largely resolved after PIBD. One BSEP deficiency recipient, who had severe graft damage, experienced recurrence of cholestasis due to the development of antibodies against BSEP after LDLT, and eventually died due to graft failure. The other patient with BSEP deficiency recovered well after LDLT and there was no evidence of posttransplant recurrence of cholestasis. In contrast, recipients with MDR3 or TJP2 deficiency showed good courses and outcomes after LDLT. Conclusions Although LDLT was considered an effective treatment for PFIC, the clinical courses and outcomes after LDLT were still inadequate in patients with FIC1 and BSEP deficiency. LDLT accompanied by total biliary diversion may not be as effective for patients with FIC1 deficiency.

Abstract
Abstract
Introduction
Severe heart failure (HF) with congenital heart disease (CHD) have demonstrated life threatening disorder despite of remarkable progress in medical therapies. Autologous skeletal myoblast sheet transplantation therapy showed clinical efficacy for left ventricular dysfunction by cytokine paracrine effects, which are expected to be sufficiently effective against right ventricular (RV) dysfunction which is often seen in end-stage of CHD patients with severe HF.
Hypothesis
An autologous skeletal myoblast sheet transplantation alleviates RV dysfunction in a pressure-overloaded right heart in a porcine model.
Methods
Five-to-six-month-old Göttingen mini-pigs underwent pulmonary artery banding with vascular occluding system. To create the porcine model of chronic pressure-overloaded right heart, vascular occluding system was gradually inflated, over a month, to make pulmonary stenosis to banding velocity >3.0 m/s measured by echocardiography (UCG), and then fixed for another month. Two months after banding, autologous skeletal myoblast sheet was placed on the epicardium of the RV free wall and followed for 2 months. Groups were as follows: control (C, n=5), sheet implantation (S, n=5). Cardiac function was measured using UCG, cardiac computed tomography (CT), and cardiac catheterization (Cath). Two months after sheet implantation, hearts were dissected for histologic analysis.
Results
Before sheet implantation, RV dysfunction was equal in groups; however, 2 months after sheet implantation, RV dysfunction and myocardial ischemia was significantly ameliorated in group S than group C. On CT, RV ejection fraction exacerbation were well controlled in Group S compared to Group C (S 44.9±2.2 vs C 31.9±2.1% [p=0.0042]). UCG and Cath revealed well maintained systolic and diastolic function in Group S compared to Group C (Tei index: S 0.42±0.06 vs C 0.70±0.07 [p=0.0240], Fraction Area Change: S 45.8±7.8 vs C 19.5±1.3% [p=0.0240], Isovolumic Relaxation Time; S 44.3±9.2 vs C 97.3±9.5 ms [p=0.0304]). On C11-Acetate Positron Emission Tomography, myocardial ischemia was more prominent in Group C compared to Group S (K mono-Rest/Stress: S 3.17±0.69 vs C 2.03±0.65 min-1 [p=0.0421], Myocardial Blood Flow-Rest/Stress: S 3.22±0.39 vs C 2.13±0.92 min-1 [p=0.0421]). In histologic analysis, Group S presented less progressed hypertrophic change in periodic acid-Schiff stain (S 13.5±0.9 vs C 18.0±3.0 μg [p=0.0240]), anti-fibrotic changes in picrosirius red stain (S 3.0±0.3 vs C 4.2±0.2% [p=0.0421]), more angiogenesis in CD31 expression (S 18.3±1.5 vs C 10.7±2.8 / 104 μm2 [p=0.0240]), and less production of reactive oxygen species in fluorescent immunostaining (S 5.9±1.7 vs C 18.4±1.7% [p=0.0304]).
Conclusion
Autologous skeletal myoblast sheet transplantation alleviates cardiomyocyte Ischemia and RV dysfunction in a porcine model of pressure-overloaded right heart.

Abstract
Introduction
How to construct massive cardiac tissue and culture it with functional improvement may be crucial as cardiomyogenesis in failed heart. We previously presented that dynamic culture in a rotating wall vessel (RWV) bioreactor could provide a better culture environment for maintenance of the engineered 3D cardiac tissue. However, it is unknown about the effect of the tissue cultured in a RWV bioreactor on engraftment and improvement of function in the distressed rat heart.
Hypothesis
We hypothesized that the engineered 3D cardiac tissue cultured in a RWV bioreactor could improve its engraftment and lead recovery of cardiac function in rat infarction model.
Methods
We made engineered cardiac tissue by seeding 2.0 × 106 human induced pluripotent stem cell derived cardiomyocytes on the PLGA fiber sheet. It was cultured in the RWV bioreactor for seven days (RWV group). For the control, static culture has been done. After in vitro assessment, these tissues were transplanted to myocardial infarction model nude rats (sham, control, and RWV group, n=10, respectively) and cardiac performance was evaluated by ultrasonography. Four weeks after transplantation, we evaluated their hearts by histological analysis.
Results
The RWV group demonstrated maturation of cardiomyocytes evidenced by significantly higher expression of Troponin T (TnT), sarcomeric α actinin (SAA), connexin 43 (Cx43) and myosin heavy chain 7 (MYH7) than the control by Western blots (TnT; 2.7±1.0 vs. 1.0±0.4, p<0.01, SAA; 2.1±0.7 vs. 1.0±0.2, p<0.01, Cx 43; 2.0±0.6 vs. 1.0±0.1, p<0.05, MYH7; 10.9±2.7 vs. 1.0±0.1, p<0.01). In the culture supernatant, the concentration of cytokines related to angiogenesis was significantly higher in the RWV group than in the control (VEGF; 29.6±7.4 vs. 12.2±4.3pg/ml, p<0.01, HGF; 72.7±9.9 vs. 42.6±5.9pg/ml, p<0.01). Four weeks after transplantation, the left ventricular ejection fraction was significantly improved in the RWV group than in the control (RWV vs. control; 47±4.9 vs. 38±6.9%, p<0.01). On histological analysis, more engineered cardiac tissue survived in the RWV group than in the control (RWV vs. control; 7/10 vs. 3/10, p=0.18). A vascular-like structure double-stained with isolectin B4 and smooth muscle actin was partially observed in the transplanted tissue. LV remodeling exhibiting extracellular collagen deposition (fibrotic area, RWV vs. control; 17±4.3 vs. 24±5.2%, p<0.05) and cardiomyocyte hypertrophy (RWV vs. control; 16±1.7 vs. 18±2.1μm, p<0.05) was significantly attenuated in RWV group than in the control. Neovascularization was significantly noted in the RWV group compared with the control (capillary density, RWV vs. control; 545±113 vs. 356±92, p<0.01).
Conclusion
Functional engineered 3D cardiac tissue cultured in a RWV bioreactor could induce angiogenesis and improved its engraftment, leading significant improvement of cardiac function in rat infarction model.

Abstract
β-1,4-acetyl-galactosaminyltransferase 2 (β4GalNT2)-knockout (KO) pigs have been produced and reveal less antigenicity to both humans and nonhuman primates (NHP). In this study, we checked the antibody response of human and NHP sera to pig cells with or without this gene. The β4GalNT2-KO porcine endothelial cell (PEC), clone #11, was first established using the plasmid pX330 expressing hCas9 and sgRNA for β4GalNT2. The glycoantigen feature on the PEC was then studied. The Sda antigen, synthesized by β4GalNT2, was slightly ascertained on wild-type (WT)-PEC, and it became null in clone #11. The PEC response to lectins was also assessed, such as Dolichos biflorus agglutinin, soybean agglutinin, and Wisteria floribunda agglutinin. All of these lectins reduced the binding reaction to clone #11 as compared with WT-PEC. Next, several human and cynomolgus sera were checked for their natural antibody reaction to both WT-PEC and clone #11. In addition, human monocyte-mediated PEC phagocytosis was assessed. However, the reduction in phagocytosis to clone #11 was not significant. Human sera showed less reactivity to the changes in antigenicity of PEC by knocking out the β4GalNT2 than cynomolgus sera.

Abstract
BACKGROUND Innate immunity by natural killer (NK) cells, macrophages, and neutrophils cause severe rejections in xenotransplantation. Therefore, the development of strategies for suppressing macrophages has considerable potential in practical applications of xenotransplantation. Recently, we found that human CD31 on swine endothelial cells (SECs) suppresses neutrophil-mediated xenogeneic rejection through homophilic binding. Since a significant amount of CD31 is expressed not only on neutrophils but also on macrophages, we studied the function of human CD31 in macrophage-mediated cytotoxicity. METHODS SECs and hCD31-transfected SECs (SEC/hCD31) were co-cultured with macrophages and cytotoxicity by macrophages was evaluated with water-soluble tetrazolium salt, or WST-8, assay. To confirm whether or not inhibitory signals are induced by hCD31 homophilic binding, the phosphorylation of the enzyme SHP-1 was investigated with Western blotting. RESULTS No suppression of cytotoxicity was induced in macrophages that had been co-cultured with SEC/CD31. However, phosphorylation of SHP-1 was induced in macrophages that had been co-cultured with SEC/hCD31. CONCLUSIONS Human CD31 on SEC may induce not only inhibitory signals but also activation signals via the binding to other receptors for hCD31.

Abstract
Abstract
Background
Although transplantation of human Adipose-derived Mesenchymal stem cell (hADSC) shows efficacy in the treatment of ischemic cardiomyopathy, its therapeutic mechanisms have not been fully elucidated. It has been already reported that mitochondria transfer to recipient cells have impact on resistance to injury and tissue regeneration, however this phenomenon has not been elucidated in the damaged heart. Therefore, we hypothesized that ADSC transfer own mitochondria to cardiomyocytes in-vivo and in-vitro under ischemic condition, resulting in the functional recovery of cardiomyocyte.
Method and result
Transplantation of hADSC (group A) to the heart surface or sham operation (group C) was performed in rats that were subjected to LAD ligation 2 weeks prior to the treatment (n=10 each). The number of transplant cell was 1x106/body. Three days after transplantation, transferred hADSCs' mitochondria were observed in recipient cardiomyocytes histologically (Figure). Quantitative PCR analysis revealed that mitochondrial genome of recipient myocytes increased over time. The cardiac function assessed with echocardiography was significantly better in group A. Furthermore, live-imaging of hADSC transplantation revealed the suspected transfer of mitochondria to beating heart.
In-vitro, the co-culture of rat cardiomyocytes (rCM) and hADSC was observed with time-lapse photography and demonstrated mitochondrial transfer under the hypoxic condition. The measuring the oxygen consumption rate (OCR) of these cells showed that OCR of rCM was reinforced by co-culture with hADSC conspicuously.
Figure 1
Conclusion
Mitochondrial transfer from hADSC to rCM was suggested in-vivo and in-vitro ischemic condition and suspected to be related to functional recovery of ischemic cardiomyocyte.

Abstract
Abstract
Background
High-mobility group box 1 protein (HMGB1) reportedly enhances CXCR4-positive bone marrow-derived mesenchymal stem cell (BM-MSC) recruitment to damaged tissue to promote tissue regeneration.
Purpose
Our aim of this study is to evaluate whether systemic administration of HMGB1 might promote tissue repair in a rat myocardial infarction (MI) model.
Methods
We prepared 26 MI model rats with high ligation of the left coronary artery. Two weeks later, HMGB1 (3 mg/kg/day) or phosphate-buffered saline (control: 3 mL/kg/day) was administered for 4 days via femoral vein. Cardiac performance was evaluated by ultrasonography, left ventricular (LV) remodeling via immunostaining. We then used immunostaining to examine MSC recruitment to damaged tissue in green fluorescent protein bone marrow transplantation (GFP-BMT) model rats, and also performed intravital imaging using two-photon microscopy to visualize BM-cells recruitment in real time.
Results
Compared with control rats, there was a significant improvement in the left ventricular ejection fraction of the HMGB1 group (HMGB1 vs. control: 48.6% ± 5.5% vs. 33.6% ± 5.4%; p<0.01) at 4 weeks after each administration. LV remodeling, characterized by interstitial fibrosis, cardiomyocyte hypertrophy, and a decrease of capillary density, was significantly attenuated in the HMGB1 group compared with control rats. On QT-PCR analysis, VEGF mRNA expression was significantly higher in the HMGB1 group than in the control (border zone; 1.6±0.6 vs. 1.1±0.2; p=0.02, septal zone; 1.1±0.1 vs. 0.9±0.1; p<0.01). In GFP-BMT rats, GFP+/PDGFR+ cells were significantly mobilized to the border zone in the HMGB1 group compared with the control (1331±197 vs. 615±45 /mm2; p<0.01), leading to formation of newly developed vasculature (Figure 1). In intravital imaging, more GFP+ cells were mobilized to the infarction area in the HMGB1 group than in the control, which was further enhanced at 12h later. Additionally, SDF-1 expression in the peri-infarction area increased significantly in MI rats compared with normal rats (MI vs. normal; 2.1±0.4 vs. 0.9±0.1; p<0.01), in where some cell-adhesions of vascular endothelial cells were destroyed.
Conclusions
Systemic administration of HMGB1 mobilized BM-MSCs to the damaged myocardium via the SDF-1/CXCR4 signaling complex. Those BM-MSCs might migrate to extracellular matrix in the border zone via the gap of each endothelial cell, leading to induction of angiogenesis and reduced fibrosis.

Abstract
PURPOSE The delayed rejection caused by strong cell-mediated innate and adaptive xenogeneic immune responses continues to be a major obstacle. Therefore, suppressing macrophage function could be effective in avoiding this type of rejection. In this study, the suppression of T-cell immunoglobulin and ITIM domain (TIGIT) function against macrophage-mediated xenogeneic rejection was investigated. MATERIAL AND METHODS Naïve porcine aortic endothelial cell (PAEC) and PAEC transfectant with TIGIT (PAEC/TIGIT) were co-cultured with M1 macrophages, and the degree of cytotoxicity was determined by a counting beads assay. The anti/pro-inflammatory gene expression was determined by RT-PCR and the phosphorylated SHP-1 in the macrophages after co-culturing with PAEC or PAEC/TIGIT was evaluated by western blotting. RESULTS CD155 was expressed at essentially equal levels on both M1 and M2 macrophages, whereas TIGIT was highly expressed on M2 macrophages but not in M1 macrophages. TIGIT on PAEC significantly reduced the cytotoxicity of M1 macrophages but no significant suppression of phagocytosis was detected. TIGIT also caused a decrease in the expression of pro-inflammatory cytokines, namely TNFα, IL-1β and IL-12 in M1 macrophages. Furthermore, PAEC/TIGIT caused a significant increase in phosphorylated SHP-1 in M1 macrophages compared to PAEC. CONCLUSION The findings of this study indicate that TIGIT suppresses xenogeneic M1 macrophage-induced cytotoxicity, probably at least in part, via the phosphorylation of SHP-1. In addition, the reduced expression of some pro-inflammatory cytokines, namely TNFα, IL-1β and IL-12, was observed in M1 macrophages that had been cultured with PAEC/TIGIT.

Abstract
Innate immunity plays a major role in xenograft rejection. However, the majority of immunosuppressants focus on inhibiting acquired immunity and not innate immunity. Therefore, a novel immunosuppressant suitable for use in conjunction with xenografts continues to be needed. It has been reported that prenylated quinolinecarboxylic acid-18 (PQA-18), a p21-activated kinase 2 (PAK2) inhibitor, exerts an immunosuppressive function on T cells. Hence, the possibility exists that PQA-18 might be used in conjunction with xenografts, which prompted us to investigate the efficacy of PQA-18 on macrophages compared with Tofacitinib, a janus kinase (JAK) inhibitor. Initial experiments confirmed that PQA-18 is non-toxic to swine endothelial cells (SECs) and human monocytes. Both PQA-18 and Tofacitinib suppressed macrophage-mediated cytotoxicity in both the differentiation and effector phases. Both PQA-18 and tofacitinib suppressed the expression of HLA-ABC by macrophages. However, contrary to Tofacitinib, PQA-18 also significantly suppressed the expression of CD11b, HLA-DR and CD40 on macrophages. PQA-18 significantly suppressed CCR7 expression on day 3 and on day 6, but Tofacitinib-induced suppression only on day 6. In a mixed lymphocyte reaction (MLR) assay, PQA-18 was found to suppress Interleukin-2 (IL-2)-stimulated T cell proliferation to a lesser extent than Tofacitinib. However, PQA-18 suppressed xenogeneic-induced T cell proliferation more strongly than Tofacitinib on day 3 and the suppression was similar on day 7. In conclusion, PQA-18 has the potential to function as an immunosuppressant for xenotransplantation.

Abstract
BACKGROUND Xenotransplantation is one of the promising strategies for overcoming the shortage of organs available for transplant. However, many immunological obstructions need to be overcome for practical use. Increasing evidence suggests that neutrophils contribute to xenogeneic cellular rejection. Neutrophils are regulated by activation and inhibitory signals to induce appropriate immune reactions and to avoid unnecessary immune reactivity. Therefore, we hypothesized that the development of neutrophil-targeted therapies may have the potential for increased graft survival in xenotransplantation. METHODS A plasmid containing a cDNA insert encoding the human CD31 gene was transfected into swine endothelial cells (SEC). HL-60 cells were differentiated into neutrophil-like cells by culturing them in the presence of 1.3% dimethyl sulfoxide for 48 hours. The cytotoxicity of the differentiated HL-60 cells (dHL-60) and peripheral blood-derived neutrophils was evaluated by WST-8 assays. To investigate the mechanism responsible for hCD31-induced immunosuppression, citrullinated histone 3 (cit-H3) and phosphorylation of SHP-1 were detected by a cit-H3 enzyme-linked immunosorbent assay (ELISA) and Western blotting, respectively. RESULTS A significant decrease in dHL-60 and neutrophil-mediated cytotoxicity in SEC/hCD31 compared with SEC was seen, as evidenced by a cytotoxicity assay. Furthermore, the suppression of NETosis and the induction of SHP-1 phosphorylation in neutrophils that had been co-cultured with SEC/CD31 were confirmed by cit-H3 ELISA and Western blotting with an anti-phosphorylated SHP-1. CONCLUSION These data suggest that human CD31 suppresses neutrophil-mediated xenogenic cytotoxicity via the inhibition of NETosis. As CD31 is widely expressed in a variety of inflammatory cells, human CD31-induced suppression may cover the entire xenogeneic cellular rejection, thus making the generation of human CD31 transgenic pigs very attractive for use in xenografts.

Abstract
OBJECTIVE Surfactant protein D (SP-D), which is secreted mainly in the lung, is an oligometric C type lectin that promotes phagocytosis by binding to carbohydrates on microbial surfaces. SP-D can also bind SIRPα, leading to a decrease in cytokine production by monocytes/macrophages. In the present study, we examined the possibility that SP-D suppresses macrophage-mediated xenogeneic cytotoxicity, by creating a membrane-type SP-D. METHODS The cDNA for the carbohydrate recognition domain (CRD) of human SP-D was switched to that of a membrane-type protein, collectin placenta 1 (CL-P1), with a Flag-tag. The cDNA of CD47 was prepared as a control. The suppressive function of the membrane-type protein of the hybrid molecule, CL-SP-D, to monocytes/macrophages was then studied and the results compared with that for CD47. RESULTS The expression of Flag-tagged CL-SP-D on the transfected SECs and the SIRPα on monocyte-like cells, THP-1 cells, was confirmed by FACS using anti-Flag Ab and anti-CD172a, respectively. The molecular size of the hybrid protein was next assessed by western blot. While significant cytotoxicity against SEC was induced in differentiated THP-1 cells, CL-SP-D significantly reduced THP-1-mediated cytotoxicity. In addition, phosphorylated SHP-1 was clearly detected in SEC/CL-SP-D in western blots. Moreover, IL-10 production was upregulated and IL-1β production was suppressed in the case of THP-1 and SEC/CL-SP-D, compared with naïve SEC. Next, the cytotoxicity caused by the in vitro generated macrophage was assessed under the same conditions as were used for THP-1. CL-SP-D also showed the significant down-regulation on the macrophage. In addition, changes in IL-10 production by the macrophage confirmed the results. CONCLUSIONS These findings indicate that the membrane-type SP-D serve as an effective therapeutic strategy for inhibiting macrophage-mediated xenograft rejection in xenotransplantation.

Abstract
PURPOSE Various strategies, such as the generation of alpha-1,3-galactosyltransferase knocked-out pigs and CD55 transgenic pigs, have been investigated to inhibit pig to human xenogeneic rejection. Our aim is to develop strategies to overcome the hurdle of not only hyper acute rejection, but also that of cellular xenogeneic rejection (CXR). Although macrophages have been well known to play a critical role in CXR, monocyte/macrophage-mediated xenogeneic rejection has not been well studied. In this study, we evaluated the effect of CD200 in xenogeneic rejection by macrophages. METHODS Naïve swine endothelial cells (SEC) and SEC/CD200 were co-cultured with M0 macrophages and the cytotoxicity was measured by a WST-8 assay. The phagocytosis of SEC and SEC/CD200 by macrophages was analyzed by flow cytometry. RESULTS While CD200 failed to suppress a significant amount of cytotoxicity against SEC by monocytes, M0 macrophage-mediated cytotoxicity was significantly suppressed by human CD200. The phagocytosis by M0 macrophages was also tested. The phagocytosis assay revealed that human CD200 suppresses M0 macrophage-mediated phagocytosis. CONCLUSIONS Our findings indicate that human CD200 suppresses the xenogeneic rejection by CD200R+ macrophages and that the generation of hCD200 transgenic pigs for use in xenografts is very attractive for preventing the macrophage-mediated rejection.

Abstract
The inhibitory function of HLA-G1, a class Ib molecule, on monocyte/macrophage-mediated cytotoxicity was examined. The expression of inhibitory receptors that interact with HLA-G, immunoglobulin-like transcript 2 (ILT2), ILT4, and KIR2DL4 (CD158d) on in vitro-generated macrophages obtained from peripheral blood mononuclear cells and the phorbol 12-myristate 13-acetate (PMA)-activated THP-1 cells were examined by flow cytometry. cDNAs of HLA-G1, HLA-G3, HLA-E, and human β2-microglobulin were prepared, transfected into pig endothelial cells (PECs), and macrophage- and the THP-1 cell-mediated PEC cytolysis was then assessed. In vitro-generated macrophages expressed not only ILT2 and ILT4 but CD158d as well. The transgenic HLA-G1 on PEC indicated a significant suppression in macrophage-mediated cytotoxicity, which was equivalent to that of transgenic HLA-E. HLA-G1 was clearly expressed on the cell surface of PEC, whereas the levels of HLA-G3 were much lower and remained in the intracellular space. On the other hand, the PMA-activated THP-1 cell was less expressed these inhibitory molecules than in vitro-generated macrophages. Therefore, the HLA-G1 on PECs showed a significant but relatively smaller suppression to THP-1 cell-mediated cytotoxicity compared to in vitro-generated macrophages. These results indicate that by generating HLA-G1, but not HLA-G3, transgenic pigs can protect porcine grafts from monocyte/macrophage-mediated cytotoxicity.

Abstract
BACKGROUND On the basis of a comparison of the hemolytic complement titer in pigs with that in humans, the complement system of pigs was investigated. The response of innate immunity, such as the natural antibodies, against humans was also examined. METHODS Hemolytic complement activity of pig serum was measured with the use of a microtitration technique. CH50 was determined according to the method of Mayer. ACH50 was assayed according to the methods of Platts-Milles and Ishizaka. Hemolytic activities of C1, C4, C2, C3, C5, C8, and C9 were estimated through the use of intermediate cells and reagents, as described previously. In addition, the pig natural anti-human antibody was studied with the use of human peripheral blood mononuclear cells (PBMCs). Human PBMCs were stained with 5% pig serum, followed by staining with fluorescein isothiocyanate-labeled goat anti-pig IgG and IgM. The resulting stained cells were quantified by use of a FACScalibur system. The alternative pathway of pig complement was also measured with the use of human erythrocytes and normal pooled pig serum with or without Mg(++)EGTA. RESULTS Both the CH50 and ACH50 titers were lower than those of humans. Concerning the components, except for C3, each component, that is, C1, C4, C2, C5, C8, and C9, was also lower than that of humans, based on measured values for human complement components. Pig serum clearly contains natural antibodies, IgG and IgM, to human PBMCs. The alternative pathway of pig complement reacted with human erythrocytes. CONCLUSIONS As a whole, pig innate immunity, the complement system and natural antibody, recognizes the surfaces of human cells.

Abstract
BACKGROUND We attempted to knock out the expression of Hanganutziu-Deicher (H-D) antigens through the use of a CRISPR (clustered regulatory interspaced short palindromic repeat)/Cas9 system for pig cytidine monophospho-N-acetylneuraminic acid hydroxylase (CMAH). METHODS Plasmids expressing hCas9 and sgRNA for pCMAH were prepared by ligating oligos into the BbsI site of pX330. The N-terminal and C-terminal EGFP coding regions overlapping 482 bp were PCR-amplified and placed under a ubiquitous CAG promoter. The approximately 400-bp genomic fragments containing the sgRNA target sequence of pCMAH were placed into the multi-cloning sites flanked by the EGFP fragments. The pCAG-EGxxFP-target was mixed with pX330 with/without the sgRNA sequences and then introduced into HEK293T cells. RESULTS Four oligos and primers, gSO1, gSO3, gSO4, and gSO8, were nominated from 8 candidates. Among them, gSO1 showed the best efficiency. Pig endothelial cells (PECs) from an α-Gal knockout pig were then used to examine the changes in the expression of the H-D antigen by the knockout of the CMAH genome by the pX330-gS01. CONCLUSIONS Changes in the expression of the H-D antigen in the PECs with the CRISPR (gS01) were clear in comparison with those in the parental cells, on the basis of FACS analysis data. The expression of the H-D antigen can be knocked out by use of the CRISPR system for pCMAH, thus confirming that this system is a very convenient system for producing knockout pigs.

Abstract
The pig pancreas is considered to be one of the most suitable sources of islets for clinical xenotransplantation. However, after producing α1-3galactosyltransferase knockout pigs, most of the organs of these pigs showed less antigenicity to the human body. Wild-type adult pig islets (APIs) that originally produced negligible levels of α-Gal, different from neonatal porcine islet-like cell clusters, showed a clear antigenicity to human serum. Concerning the so-called non-Gal epitopes, many studies related to glycoproteins and glycolipids are ongoing in efforts to identify them. However, our knowledge of non-Gal glycoantigens remains incomplete. In our previous study, N-glycans were isolated from APIs, and the structures of 28 of the N-glycans were detected. In this study, to identify additional structures, further analyses were performed by liquid chromatography-mass spectrometry (LC-MS). N-glycans were isolated from APIs by the method described by O'Neil et al with minor modifications and LC-MS-based structural analyses were then performed. The detected N-glycan peaks in the LC-MS spectra were selected using the FLexAnalysis software program and the structures of the glycans were predicted using the GlyocoMod Tool. The API preparation contained 11 peaks and 16 structures were then nominated as containing N-linked sugars. Among them, 5 sulfated glycans were estimated, confirming the existence of sulfate structures in N-glycans in API. In addition, these data may supplement several N-glycan structures that contain two deoxyhexose units, such as fucose, to our previous report. The data herein will be helpful for future studies of antigenicity associated with API.

Abstract
BACKGROUND In our previous study, we reported on the development of substituting S147C for HLA-E as a useful gene tool for xenotransplantation. In this study we exchanged the codon of HLA-Ev (147), checked its function, and established a line of transgenic mice. METHODS A new construct, a codon exchanging human HLA-Ev (147) + IRES + human beta 2-microgloblin, was established. The construct was subcloned into pCXN2 (the chick beta-actin promoter and cytomegalovirus enhancer) vector. Natural killer cell- and macrophage-mediated cytotoxicities were performed using the established the pig endothelial cell (PEC) line with the new gene. Transgenic mice with it were next produced using a micro-injection method. RESULTS The expression of the molecule on PECs was confirmed by the transfection of the plasmid. The established molecules on PECs functioned well in regulating natural killer cell-mediated cytotoxicity and macrophage-mediated cytotoxicity. We have also successfully generated several lines of transgenic mice with this plasmid. The expression of HLA-Ev (147) in each mouse organ was confirmed by assessing the mRNA. The chick beta-actin promoter and cytomegalovirus enhancer resulted in a relatively broad expression of the gene in each organ, and a strong expression in the cases of the heart and lung. CONCLUSION A synthetic HLA-Ev (147) gene with a codon usage optimized to a mammalian system represents a critical factor in the development of transgenic animals for xenotransplantation.

Abstract
Background The association of complement with the progression of acute T cell mediated rejection (ATCMR) is not well understood. We investigated the production of complement components and the expression of complement regulatory proteins (Cregs) in acute T-cell mediated rejection using rat and human renal allografts. Methods We prepared rat allograft and syngeneic graft models of renal transplantation. The expression of Complement components and Cregs was assessed in the rat grafts using quantitative real-time PCR (qRT-PCR) and immunofluorescent staining. We also administered anti-Crry and anti-CD59 antibodies to the rat allograft model. Further, we assessed the relationship between the expression of membrane cofactor protein (MCP) by immunohistochemical staining in human renal grafts and their clinical course. Results qRT-PCR results showed that the expression of Cregs, CD59 and rodent-specific complement regulator complement receptor 1-related gene/protein-y (Crry), was diminished in the rat allograft model especially on day 5 after transplantation in comparison with the syngeneic model. In contrast, the expression of complement components and receptors: C3, C3a receptor, C5a receptor, Factor B, C9, C1q, was increased, but not the expression of C4 and C5, indicating a possible activation of the alternative pathway. When anti-Crry and anti-CD59 mAbs were administered to the allograft, the survival period for each group was shortened. In the human ATCMR cases, the group with higher MCP expression in the grafts showed improved serum creatinine levels after the ATCMR treatment as well as a better 5-year graft survival rate. Conclusions We conclude that the expression of Cregs in allografts is connected with ATCMR. Our results suggest that controlling complement activation in renal grafts can be a new strategy for the treatment of ATCMR.

Abstract
Induced pluripotent stem cells (iPSCs) can serve as a source of cardiomyocytes (CMs) to treat end-stage heart failure; however, transplantation of genetically dissimilar iPSCs even within species (allogeneic) can induce immune rejection. We hypothesized that this might be limited by matching the major histocompatibility complex (MHC) antigens between the donor and the recipient. We therefore transplanted fluorescence-labeled (GFP) iPSC-CMs donated from a macaque with homozygous MHC haplotypes into the subcutaneous tissue and hearts of macaques having heterozygous MHC haplotypes (MHC-matched; group I) or without identical MHC alleles (group II) in conjunction with immune suppression. Group I displayed a higher GFP intensity and less immune-cell infiltration in the graft than group II. However, MHC-matched transplantation with single or no immune-suppressive drugs still induced a substantial host immune response to the graft. Thus, the immunogenicity of allogeneic iPSC-CMs was reduced by MHC-matched transplantation although a requirement for appropriate immune suppression was retained for successful engraftment. Cardiomyocytes from iPSCs can treat heart disease iPSC-CMs were transplanted into MHC-matched or unmatched cynomolgus macacques Matched iPSC-CM grafts had better survival and less host rejection immune response Immunosuppression was still required for successful allogeneic iPSC-CM engraftment

Abstract
UNLABELLED Cell-surface glycans vary widely, depending on cell properties. Previously, we reported that the pattern of N-glycan expression on murine induced pluripotent stem cells (iPSCs) changed toward that of the cardiac tissue during cardiomyogenic differentiation. In this study, N-glycans were isolated from human iPSCs, iPSC-derived cardiomyocytes (iPSC-CMs), and human cardiomyocytes (hCMCs). Their structures were analyzed by a mapping technique based on high-performance liquid chromatography elution positions and matrix-assisted laser desorption/ionization time-of-flight mass-spectrometric data. Of 52 isolated N-glycans, the structures of 38 were clearly identified. In addition, 11 structures were partially identified because the binding style and fucose binding site at the nonreduced terminal could not be identified. Quantitation of each type of N-glycan, based on the terminal glycosylation process, revealed that the exposed N-acetylglucosamine (GlcNAc) and the nonreduced terminal fucose types decreased, whereas the exposed galactose or the α2-3 NeuAc types increased in the iPSCs during cardiomyogenic differentiation. However, the bisecting GlcNAc and the triantennary structures were found in relative abundance in the iPSC-CMs in comparison with hCMCs or iPSCs. Expression of MGAT3, a glycosyltransferase-encoding gene that produces the bisecting GlcNAc structures, was higher in iPSCs and iPSC-CMs than in hCMCs. These findings will prove useful in understanding the directional precision of cardiomyogenic differentiation in vitro. SIGNIFICANCE This study focused on N-glycans produced in human induced pluripotent stem cells (iPSCs) and iPSC-derived cardiomyocytes to investigate their change on cardiomyogenic differentiation in vitro. This shows that the expression pattern of N-glycans in human iPSCs changed toward the pattern observed in human cardiomyocytes upon cardiomyogenic differentiation. Structural differences were also observed in the bisecting N-acetylglucosamine and the triantennary structures upon cardiomyogenic differentiation. The findings of this study will help in understanding the directional precision of cardiomyogenic differentiation in vitro.

Abstract
Zinc-finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) are new tools for
producing gene knockout (KO) animals. The current study reports produced genetically modified pigs, in which
two endogenous genes were knocked out. Porcine fibroblast cell lines were derived from homozygous
α1,3-galactosyltransferase (GalT) KO pigs. These cells were subjected to an additional KO for
the cytidine monophospho-N-acetylneuraminic acid hydroxylase (CMAH) gene. A
pair of ZFN-encoding mRNAs targeting exon 8 of the CMAH gene was used to generate the
heterozygous CMAH KO cells, from which cloned pigs were produced by somatic cell nuclear
transfer (SCNT). One of the cloned pigs obtained was re-cloned after additional KO of the remaining
CMAH allele using the same ZFN-encoding mRNAs to generate
GalT/CMAH-double homozygous KO pigs. On the other hand, the use of
TALEN-encoding mRNAs targeting exon 7 of the CMAH gene resulted in efficient generation of
homozygous CMAH KO cells. These cells were used for SCNT to produce cloned pigs homozygous
for a double GalT/CMAH KO. These results demonstrate that the combination of
TALEN-encoding mRNA, in vitro selection of the nuclear donor cells and SCNT provides a robust
method for generating KO pigs.

Abstract
BACKGROUND Xenotransplantation is considered to be one of the most attractive strategies for overcoming the worldwide shortage of organs. However, many obstructions need to be overcome before it will achieve clinical use in patients. One such obstacle is the development of an effective immunosuppressive strategy. We previously reported that myeloid-derived suppressor cells (MDSCs), a heterogeneous population of progenitor and immature myeloid cells, suppress xenogenic CTL-mediated cytotoxicity. Because of their heterogeneous nature, MDSC can function via several suppressive mechanisms that disrupt both innate and adaptive immunity. Since macrophages play a pivotal role in the rejection of a xenograft, in this study, we evaluated the suppressive effects of MDSC against macrophage-mediated xenogenic rejection. MATERIALS AND METHODS To evaluate the effect of monocyte-derived MDSCs on xenogenic immune reactions, a CFSE(carboxyfluorescein diacetate, succinimidyl ester)assay was employed to assess cytotoxicity. RESULTS While, in the absence of activation, primed MDSCs had no detectable effect on macrophage-induced cytotoxicity against SEC cells, LPS-activated MDSCs were found to significantly suppress xenogenic cytotoxicity. A CFSE cytotoxicity assay revealed that MDSCs significantly suppressed macrophage-induced cytotoxicity. Furthermore, an indoleamine 2,3 dioxygenase (IDO) inhibitor, 1-methyl tryptophan (1-MT), abolished the MDSC-induced suppression of macrophage-mediated xeno-rejection, indicating that MDSCs may suppress macrophage-mediated cytotoxicity in an IDO-dependent manner. CONCLUSION These findings indicate that MDSCs have great potential for immunosuppressing macrophage-mediated xeno-rejection.
