Abstract
Xenotransplantation promises to alleviate the issue of donor organ shortages and to decrease waiting times for transplantation. Recent advances in genetic engineering have allowed for the creation of pigs with up to 16 genetic modifications. Several combinations of genetic modifications have been associated with extended graft survival and life-supporting function in experimental heart and kidney xenotransplants. Lung xenotransplantation carries specific challenges related to the large surface area of the lung vascular bed, its innate immune system's intrinsic hyperreactivity to perceived 'danger', and its anatomic vulnerability to airway flooding after even localized loss of alveolocapillary barrier function. This article discusses the current status of lung xenotransplantation, and challenges related to immunology, physiology, anatomy, and infection. Tissue engineering as a feasible alternative to develop a viable lung replacement solution is discussed.

Abstract
A major limitation of organ allotransplantation is the insufficient supply of donor organs. Consequently, thousands of patients die every year while waiting for a transplant. Progress in xenotransplantation that has permitted pig organ graft survivals of years in non-human primates has led to renewed excitement about the potential of this approach to alleviate the organ shortage. In 2022, the first pig-to-human heart transplant was performed on a compassionate use basis, and xenotransplantation experiments using pig kidneys in deceased human recipients provided encouraging data. Many advances in xenotransplantation have resulted from improvements in the ability to genetically modify pigs using CRISPR-Cas9 and other methodologies. Gene editing has the capacity to generate pig organs that more closely resemble those of humans and are hence more physiologically compatible and less prone to rejection. Despite such modifications, immune responses to xenografts remain powerful and multi-faceted, involving innate immune components that do not attack allografts. Thus, the induction of innate and adaptive immune tolerance to prevent rejection while preserving the capacity of the immune system to protect the recipient and the graft from infection is desirable to enable clinical xenotransplantation.

Abstract
Eliminating major xenoantigens in pig cells has drastically reduced human antibody-mediated hyperacute xenograft rejection (HXR). Despite these advancements, acute xenograft rejection (AXR) remains one of the major obstacles to clinical xenotransplantation, mediated by innate immune cells, including macrophages, neutrophils, and natural killer (NK) cells. NK cells play an ‘effector’ role by releasing cytotoxicity granules against xenogeneic cells and an ‘affecter’ role on other immune cells through cytokine secretion. We highlight the key receptor-ligand interactions that determine the NK cell response to target cells, focusing on the regulation of NK cell activating receptor (NKG2D, DNAM1) and inhibitory receptor (KIR2DL1-4, NKG2A, and LIR-1) signaling pathways. Inhibition of NK cell activity may protect xenografts from cytotoxicity. Recent successful approaches to reducing NK cell-mediated HXR and AXR are reviewed, including genetic modifications of porcine xenografts aimed at improving pig-to-human compatibility. Future directions to promote xenograft acceptance are discussed, including NK cell tolerance in pregnancy and NK cell evasion in viral infection.

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
Xenotransplantation may become the highly desired solution to close the gap between the availability of donated organs and number of patients on the waiting list. In recent years, enormous progress has been made in the development of genetically engineered donor pigs. The introduced genetic modifications showed to be efficient in prolonging xenograft survival. In this review, we focus on the type of immune responses that may target xeno-organs after transplantation and promising immunogenetic modifications that show a beneficial effect in ameliorating or eliminating harmful xenogeneic immune responses. Increasing histocompatibility of xenografts by eliminating genetic discrepancies between species will pave their way into clinical application.

Abstract
The last 15 years or so have seen exciting progress in xenotransplantation, with porcine organ grafts surviving months or even years in non-human primates. These advances reflect the application of new scientific knowledge, improved immunosuppressive agents, and genetic engineering. The field has recently enjoyed a renaissance of interest and hope, largely due to the exponential increase in our capacity to genetically engineer porcine source animals. However, immune responses to xenografts are very powerful and widespread clinical application of xenotransplantation will depend on the ability to suppress these immune responses while preserving the capacity to protect both the recipient and the graft from infectious microorganisms. Our work over the last three decades has aimed to engineer the immune system of the recipient in a manner that achieves specific tolerance to the xenogeneic donor while preserving otherwise normal immune function. Important proofs of principle have been obtained, first in rodents, and later in human immune systems in "humanized mice" and finally in non-human primates, demonstrating the capacity and potential synergy of mixed xenogeneic chimerism and xenogeneic thymic transplantation in tolerizing multiple arms of the immune system. Considering the fact that clinical tolerance has recently been achieved for allografts and the even greater importance of avoiding excessive immunosuppression for xenografts, it is my belief that it is both possible and imperative that we likewise achieve xenograft tolerance. I expect this to be accomplished through the availability of targeted approaches to recipient immune conditioning, understanding of immunological mechanisms of tolerance, advanced knowledge of physiological incompatibilities, and the availability of inbred miniature swine with optimized use of genetic engineering.

Abstract
For advanced hepatocellular carcinoma (HCC) patients, liver transplantation (LT) is an optimal treatment with limitation of high risk of tumor recurrence related to the immunosuppressive chemotherapy as usually recommended. In this study, a 29-year-old man suffered from HCC recurrence after LT. He underwent radiotherapy (total dose: 45 Gy) but had no significant response. Then, he received iodine-125 seed implantation combined with allogenic natural killer (NK) cell immunotherapy. Liver function, immune function, circulating tumor cell counts and computed tomography scans were evaluated to determine the clinical effect. We found that this combined treatment produced enhanced immune function of the patient and reduction in tumor size. This is the first report of an efficacy and safety study about clinical regimen comprising allogenic NK cell immunotherapy combined with iodine-125 seed implantation for the treatment of HCC recurrence after LT.

Abstract
Abstract
The use of pigs as a source of organs and tissues for xenotransplantation can overcome the growing shortage of human donors. Human NK cells play an important role in the cell-mediated rejection of pig-to-human xenografts. In this paper we report the generation and extensive characterization of three generations of transgenic pigs with HLA-E gene encoding the antigen which can inhibit the human NK cell-mediated response. The gene construct pHLAE-GFPBsd containing the human gene encoding the human leukocyte antigen under the promoter of the EF-1α elongation factor ensuring systemic expression was introduced by microinjection into a pronucleus of the fertilized porcine oocyte. PCR analysis revealed and FISH analysis confirmed that the pHLAE-GFPBsd gene construct was present in the genome of the founder female pig. As a result of inter-breeding, an additional 7 transgenic animals were obtained (one individual from F1 generation and six individuals from F2 generation). The transgene expression was shown by RT-PCR and flow cytometry. Real Time PCR analysis estimated the approximate number of transgene copies at 16–34. Karyotype analysis did not show any changes in the structure or the number of chromosomes. The expression level of the transgene was stable in the next generation of genetically modified pigs. An NK cell-mediated cytotoxicity assay showed the increased viability of the transgenic cells in comparison with the wild-type, which confirmed the protective influence of HLA-E expression.

Abstract
In this study, the safety and clinical efficacy of cryosurgery combined with allogenic NK cell immunotherapy for the treatment of advanced non-small cell lung cancer (NSCLC) were evaluated. From July 2016 to March 2017, we enrolled 60 patients who met the enrollment criteria and divided them into two groups: (1) the simple cryoablation group (n = 30) and (2) the cryoablation combined with allogenic NK cell group (n = 30). The changes in immune function, quality of life, and clinical response were evaluated. We found that allogenic NK cells combined with cryosurgical treatment for advanced NSCLC have a synergistic effect, which not only enhancing the immune function of patients, improving the quality of life, and significantly increasing the response rate (RR) and disease control rate (DCR) compared to cryoablation group. This study is the first clinical trial of allogenic NK cells combined with cryosurgery for the treatment of advanced NSCLC and preliminaily its safety and efficacy.

Abstract
Recruitment of human NK cells to porcine tissues has been demonstrated in pig organs perfused ex vivo with human blood in the early 1990s. Subsequently, the molecular mechanisms leading to adhesion and cytotoxicity in human NK cell-porcine endothelial cell (pEC) interactions have been elucidated in vitro to identify targets for therapeutic interventions. Specific molecular strategies to overcome human anti-pig NK cell responses include (1) blocking of the molecular events leading to recruitment (chemotaxis, adhesion, and transmigration), (2) expression of human MHC class I molecules on pECs that inhibit NK cells, and (3) elimination or blocking of pig ligands for activating human NK receptors. The potential of cell-based strategies including tolerogenic dendritic cells (DC) and regulatory T cells (Treg) and the latest progress using transgenic pigs genetically modified to reduce xenogeneic NK cell responses are discussed. Finally, we present the status of phenotypic and functional characterization of nonhuman primate (NHP) NK cells, essential for studying their role in xenograft rejection using preclinical pig-to-NHP models, and summarize key advances and important perspectives for future research.

Abstract
BACKGROUND In pig-to-human xenotransplantation, interactions between human natural killer (NK) cells and porcine endothelial cells (pEC) are characterized by recruitment and cytotoxicity. Protection from xenogeneic NK cytotoxicity can be achieved in vitro by the expression of the non-classical human leukocyte antigen-E (HLA-E) on pEC. Thus, the aim of this study was to analyze NK cell responses to vascularized xenografts using an ex vivo perfusion system of pig limbs with human blood. METHODS Six pig forelimbs per group, respectively, stemming from either wild-type (wt) or HLA-E/hCD46 double-transgenic (tg) animals, were perfused ex vivo with heparinized human blood for 12 hours. Blood samples were collected at defined time intervals, cell numbers counted, and peripheral blood mononuclear cells analyzed for phenotype by flow cytometry. Muscle biopsies were analyzed for NK cell infiltration. In vitro NK cytotoxicity assays were performed using pEC derived from wt and tg animals as target cells. RESULTS Ex vivo, a strong reduction in circulating human CD45 leukocytes was observed after 60 minutes of xenoperfusion in both wt and tg limb groups. NK cell numbers dropped significantly. Within the first 10 minutes, the decrease in NK cells was more significant in the wt limb perfusions as compared to tg limbs. Immunohistology of biopsies taken after 12 hours showed less NK cell tissue infiltration in the tg limbs. In vitro, NK cytotoxicity against hCD46 single tg pEC and wt pEC was similar, while lysis of double tg HLA-E/hCD46 pEC was significantly reduced. Finally, circulating cells of pig origin were observed during the ex vivo xenoperfusions. These cells expressed phenotypes mainly of monocytes, B and T lymphocytes, NK cells, as well as some activated endothelial cells. CONCLUSIONS Ex vivo perfusion of pig forelimbs using whole human blood represents a powerful tool to study humoral and early cell-mediated rejection mechanisms of vascularized pig-to-human xenotransplantation, although there are several limitations of the model. Here, we show that (i) transgenic expression of HLA-E/hCD46 in pig limbs provides partial protection from human NK cell-mediated xeno responses and (ii) the emergence of a pig cell population during xenoperfusions with implications for the immunogenicity of xenografts.

Abstract
Purpose To study the safety and clinical efficacy on combination of irreversible electroporation and allogeneic natural killer cell therapy for treating Stage III/IV pancreatic cancer, evaluating median progression free survival (PFS), and overall survival (OS). Results Adverse events of all patients were limited to grades 1 and 2, including local (mainly tussis 13.4%, nausea and emesis 7.1%, pain of puncture point 29.6% and duodenum and gastric retention 4.3%) and systemic (mainly fatigue 22.3%, fever 31.6%, and transient reduction of intraoperative blood pressure 25.1% and white cell count reduction 18.3%) reactions, fever was the most frequent. The serum amylase level at 24 h and 7 d after IRE was not significantly changed compared to those before IRE (P > 0.05). CA19–9 value was lower in IRE-NK group than in IRE at 1 month after treatment (P < 0.05). After a median follow-up of 7.4 months (3.6–11.2 months): in stage III group, median PFS was higher in IRE-NK group (9.3 months) than in IRE group (8.1 months, P = 0.0465), median OS was higher in IRE-NK (13.2 months) than in IRE (11.4 months, P = 0.0411), and median PFS was higher in who received multiple NK than single NK (9.8 months vs.8.1 months, P = 0.0423, respectively), median OS who received multiple NK was higher than single NK (13.9 months vs.12.3 months, P = 0.0524, respectively), the RR in IRE-NK (63.2%) was higher than in IRE (50.0%, P < 0.05); in stage IV group, median OS was higher in IRE-NK (9.8 months) than in IRE (8.7 months, P = 0.0397), the DCR in IRE-NK (66.7%) was higher than in IRE (42.9%, P < 0.05). Materials and Methods Between July 2016 and May 2017, we enrolled 71 patients who met the enrollment criteria. The patients were divided into stage III (32 patients, 17 patients received only IRE and 15 patients received IRE-NK (Irreversible electroporation- natural killer): 8 patients underwent a course of NK and 7 patients underwent ≥ 3 courses) and stage IV (39 patients, 22 patients received only IRE and 17 patients received IRE-NK: 9 patients underwent a course of NK and 8 patients underwent ≥ 3 courses). The safety and short-term effects were evaluated firstly, then the median PFS, median OS, response rate (RR) and disease control rate (DCR) were assessed. Conclusions Combination of irreversible electroporation and allogeneic natural killer cell immunotherapy significantly increased median PFS and median OS in stage III pancreatic cancer and extended the median OS of stage IV pancreatic cancer. Multiple allogeneic natural killer cells infusion was associated with better prognosis to stage III pancreatic cancer.

Tumor cryoablation in combination with natural killer cells therapy and Herceptin in patients with HER2-overexpressing recurrent breast cancer. Mol Immunol 2017; 92:45-53. [PMID: 29040918 DOI: 10.1016/j.molimm.2017.10.003] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2017] [Revised: 09/26/2017] [Accepted: 10/04/2017] [Indexed: 12/18/2022]
Abstract
In this study, we investigated the clinical benefits of a combination of tumor cryoablation with natural killer (NK) cells therapy and Herceptin for human epidermal growth factor (HER) 2-overexpressing recurrent breast cancer. From May 2015 to May 2016, 48 patients who met the enrollment criteria were assigned to three groups (n=16): cryoablation group (group I), cryoablation-NK cells therapy group (group II) and cryoablation-NK cells therapy-Herceptin group (group III). Safety and short-term effects were evaluated. All the adverse effects were manageable and acceptable. The three-therapy combination treatment not only yielded good clinical efficacy, it also improved the quality of life; reduced levels of circulating tumor cells (CTCs); reduced carcino-embryonic antigen (CEA) and cancer antigen 15-3 (CA15-3) expression; enhanced immune function significantly. Furthermore, it can resulte in significant prolongation of progression free survival (PFS). This is the first clinical study to demonstrate the benefit of the three-therapy combination of tumor cryoablation, NK cells therapy, and Herceptin for HER2-overexpressing recurrent breast cancer.

Abstract
In this study, we determined the number of peripheral blood circulating tumor cells (CTCs) pre- and post-NK in patients with stage IV non- small cell lung cancer (NSCLC) as a reference for understanding the relevance of any changes to the efficacy of NK cells therapy. The patients were given one to three courses of immunotherapy. CTC numbers and CTC-related gene expression were measured in the peripheral blood of 31 patients with stage IV NSCLC at 1day before and 7 and 30d after NK cells therapy using magnetic activated cell sorting (MACS) and fluorescence activated cell sorting (FACS) combined with real-time quantitative PCR (RT-qPCR). Throughout the research, fever was the most common reaction (34.6%). The number of CTCs was 18.11±5.813, 15.13±5.984 and 10.32±5.623, respectively, and this decreased significantly over time. ΔCt values for the CTC-related genes CEA, MAGE-3 and CK18 increased significantly after NK cells infusion. The expression of CEA, CK18 and MAGE-3 decreased significantly with time after NK. CTC was a useful biomarker for evaluating the efficacy of NK cells therapy on stage IV NSCLC.

Abstract
PURPOSE This study was attempted to investigate the safety and clinical efficacy of percutaneous irreversible electroporation combined with allogeneic natural killer cell therapy for treating stage III/IV pancreatic cancer, evaluate median progression-free survival (PFS), and overall survival (OS). METHODS Between March 2016 and February 2017, we enrolled 67 patients who met the enrollment criteria. According to the latest NCCN Guidelines, the patients were divided into stage III (35 patients, 16 patients received only irreversible electroporation (IRE) and 19 patients received IRE-NK: 8 patients underwent one course NK and 11 patients underwent ≥3 courses) and stage IV (32 patients, 14 patients received only IRE and 18 patients received IRE-NK: 8 patients underwent one course NK and 10 patients underwent ≥3 courses). The safety and short-term effects were evaluated first, then the median PFS, median OS, response rate (RR) and disease control rate (DCR) were assessed. RESULTS Adverse events of all patients were limited to grades A and B, included local (mainly cough 12.7%, nausea and emesis 6.8%, pain of puncture point 25.3% and duodenum and gastric retention 5.9%) and systemic (mainly fatigue 21.5, fever 33.5%, and blood pressure intraoperative transient reduction 27.4% and white cell count reduction 22.6%) reactions, fever was most frequent. The serum amylase level at 24 h and 7 d after IRE was not significantly changed compared to those before IRE (P > 0.05). CA19-9 value was lower in IRE-NK group than in IRE at 1 month after treatment (P < 0.05). After a median follow-up of 7.9 months (3.8-12.1 months): in stage III group, median PFS was higher in IRE-NK group (9.1 months) than in IRE group (7.9 months, P = 0.0432), median OS was higher in IRE-NK (13.6 months) than in IRE (12.2 months; P = 0.0327), and median PFS was higher in who received multiple NK than single NK (9.9 vs. 8.2 months; P = 0.0387, respectively), median OS who received multiple NK was higher than single NK (13.7 vs. 12.1 months; P = 0.0451, respectively), the RR in IRE-NK (63.2%) was higher than in IRE (50.0%; P < 0.05); in stage IV group, median OS was higher in IRE-NK (10.2 months) than in IRE (9.1 months; P = 0.0367), the DCR in IRE-NK (66.7%) was higher than in IRE (42.9%; P < 0.05). CONCLUSION Percutaneous irreversible electroporation combined with allogeneic natural killer cell immunotherapy significantly increased median PFS and median OS in stage III pancreatic cancer and extended the median OS of stage IV pancreatic cancer. Multiple allogeneic natural killer cells infusion was associated with better prognosis to stage III pancreatic cancer.

Abstract
In the present study, we aimed to compare the clinical outcome of autogeneic and allogeneic natural killer (NK) cells immunotherapy for the treatment of recurrent breast cancer. Between July 2016 and February 2017, 36 patients who met the enrollment criteria were randomly assigned to two groups: autogeneic NK cells immunotherapy group (group I, n=18) and allogeneic NK cells immunotherapy group (group II, n=18). The clinical efficacy, quality of life, immune function, circulating tumor cell (CTC) level, and other related indicators were evaluated. We found that allogeneic NK cells immunotherapy has better clinical efficacy than autogeneic therapy. Moreover, allogeneic NK cells therapy improves the quality of life, reduces the number of CTCs, reduces carcinoembryonic antigen and cancer antigen 15-3 (CA15-3) expression, and significantly enhances immune function. To our knowledge, this is the first clinical trial to compare the clinical outcome of autogeneic and allogeneic NK cells immunotherapy for recurrent breast cancer.

Abstract
In this study, the clinical efficacy of cryosurgery combined with allogenic natural killer cell immunotherapy for advanced hepatocellular cancer was evaluated. From October 2015 to March 2017, we enrolled 61 patients who met the enrollment criteria and divided them into two groups: 1) the simple cryoablation group (Cryo group, n = 26); and 2) the cryoablation combined with allogenic natural killer cells group (Cryo-NK group, n = 35), the safety and short-term effects were evaluated firstly, then the median progression-free survival, response rate and disease control rate were assessed. All adverse events experienced by the patients were recorded, and included local (e.g., pain, pleural effusion, and ascites) and systemic (e.g., chills, fatigue, and fever) reactions, fever was more frequent. Other possible seriously side effects (e.g., blood or bone marrow changes) were not detected. Combining allogeneic natural killer cells with cryoablation had a synergistic effect, not only enhancing the immune function, improving the quality of life of the patients, but also reducing the expression of AFP and significantly exhibiting good clinical efficacy of the patients. After a median follow-up of 8.7 months (3.9 -15.1months), median progression-free survival was higher in Cryo-NK (9.1 months) than in Cryo (7.6 months, P = 0.0107), median progression-free survival who received multiple natural killer was higher than who just received single natural killer (9.7 months vs.8.4 months, P = 0.0011, respectively), the response rate in Cryo-NK (60.0%) was higher than in Cryo (46.1%, P < 0.05), the disease control rate in Cryo-NK (85.7%) was higher than in Cryo group (69.2%, P < 0.01). Percutaneous cryoablation combined with allogeneic natural killer cell immunotherapy significantly increased median progression-free survival of advanced hepatocellular cancer patients. Multiple allogeneic natural killer cells infusion was associated with better prognosis to advanced hepatocellular cancer.

Abstract
We investigated the effectiveness of adoptive transfer of KIR ligand-mismatched highly activated nature killer (HANK) cells in patients with hepatic carcinoma. Peripheral blood mononuclear cells were obtained and cultured in vitro to induce expansion and activation of HANK cells. After 12 d of culture, the cells were divided into 3 parts and infused intravenously on days 13 to 15. The patients (n = 16) were given one to 6 courses of immunotherapy. No side effects were observed. The lymphocyte subsets and cytokine, thymidine kinase 1 (TK1) and circulating tumor cell (CTC) levels were measured 1 day before treatment and 1 month after the final infusion: the absolute number of total T cells and NK cells and the IL-2 and TNF-β levels were significantly higher, and the TK1 and CTC levels were significantly lower at 1 month after treatment. The percentage of patients who experienced partial response, disease stabilization, and disease progression at 3 months after treatment was 18.8%, 50.0% and 31.2%, respectively. The total follow-up period was 2-12 months. The median progression-free survival from treatment was 7.5 months. This is the first study on the benefits of HANK cell immunotherapy for hepatic carcinoma These encouraging preliminary observations imply that HANK cell immunotherapy is safe, can improve the immune function of patients with liver cancer, and may even reduce the rate of tumor metastasis and recurrence. However, further studies on larger samples of patients with a longer follow-up period are required to confirm these findings.

Abstract
Antibody-mediated rejection (AMR) has been identified among the most important factors limiting long-term outcome in cardiac and renal transplantation. Therapeutic management remains challenging and the development of effective treatment modalities is hampered by insufficient understanding of the underlying pathophysiology. However, recent findings indicate that in addition to AMR-triggered activation of the classical complement pathway, antibody-dependent cellular cytotoxicity by innate immune cell subsets also promotes vascular graft injury. This review summarizes the accumulating evidence for the contribution of natural killer cells, the key mediators of antibody-dependent cellular cytotoxicity, to human AMR in allotransplantation and xenotransplantation and illustrates the current mechanistic conceptions drawn from animal models.

Abstract
The discrepancy between organ need and organ availability represents one of the major limitations in the field of transplantation. One possible solution to this problem is xenotransplantation. Research in this field has identified several obstacles that have so far prevented the successful development of clinical xenotransplantation protocols. The main immunologic barriers include strong T-cell and B-cell responses to solid organ and cellular xenografts. In addition, components of the innate immune system can mediate xenograft rejection. Here, we review these immunologic and physiologic barriers and describe some of the strategies that we and others have developed to overcome them. We also describe the development of two strategies to induce tolerance across the xenogeneic barrier, namely thymus transplantation and mixed chimerism, from their inception in rodent models through their current progress in preclinical large animal models. We believe that the addition of further beneficial transgenes to Gal knockout swine, combined with new therapies such as Treg administration, will allow for successful clinical application of xenotransplantation.

Abstract
The use of animals as donors of tissues and organs for xenotransplantations may help in meeting the increasing demand for organs for human transplantations. Clinical studies indicate that the domestic pig best satisfies the criteria of organ suitability for xenotransplantation. However, the considerable phylogenetic distance between humans and the pig causes tremendous immunological problems after transplantation, thus genetic modifications need to be introduced to the porcine genome, with the aim of reducing xenotransplant immunogenicity. Advances in genetic engineering have facilitated the incorporation of human genes regulating the complement into the porcine genome, knockout of the gene encoding the formation of the Gal antigen (α1,3-galactosyltransferase) or modification of surface proteins in donor cells. The next step is two-fold. Firstly, to inhibit processes of cell-mediated xenograft rejection, involving natural killer cells and macrophages. Secondly, to inhibit rejection caused by the incompatibility of proteins participating in the regulation of the coagulation system, which leads to a disruption of the equilibrium in pro- and anti-coagulant activity. Only a simultaneous incorporation of several gene constructs will make it possible to produce multitransgenic animals whose organs, when transplanted to human recipients, would be resistant to hyperacute and delayed xenograft rejection.

Abstract
Xenotransplantation is an innovative field of research with the potential to provide us with an alternative source of organs to face the severe shortage of human organ donors. For several reasons, pigs have been chosen as the most suitable source of organs and tissues for transplantation in humans. However, porcine xenografts undergo cellular immune responses representing a major barrier to their acceptance and normal functioning. Innate and adaptive xenogeneic immunity is mediated by both the recognition of xenogeneic tissue antigens and the lack of inhibition due to molecular cross-species incompatibilities of regulatory pathways. Therefore, the delivery of immunoreceptor tyrosine-based inhibitory motif (ITIM)-dependent and related negative signals to control innate (NK cells, macrophages) and adaptive T and B cells might overcome cell-mediated xenogeneic immunity. The proof of this concept has already been achieved in vitro by the transgenic overexpression of human ligands of several inhibitory receptors in porcine cells resulting in their resistance against xenoreactivity. Consequently, several transgenic pigs expressing tissue-specific human ligands of inhibitory coreceptors (HLA-E, CD47) or soluble competitors of costimulation (belatacept) have already been generated. The development of these robust and innovative approaches to modulate human anti-pig cellular immune responses, complementary to conventional immunosuppression, will help to achieve long-term xenograft survival. In this review, we will focus on the current strategies to enhance negative signaling pathways for the regulation of undesirable cell-mediated xenoreactive immune responses.

Abstract
PURPOSE OF REVIEW This review assesses the recent progress in xenograft rejection by innate immune responses, with a focus on innate cellular xenoreactivity. RECENT FINDINGS Current literature was reviewed for new insights into the role of innate cellular immunity in xenograft rejection. Increasing evidence confirms that vigorous innate immune cell activation is accounted for by a combination of xenoantigen recognition by activating receptors, and incompatibility in inhibitory receptor-ligand interactions. Although both innate humoral and cellular xenoimmune responses are predominantly elicited by preformed and induced xenoreactive antibodies in nonhuman primates following porcine xenotransplantation, innate immune cells can also be activated by xenografts in the absence of antibodies. The latter antibody-independent response will likely persist in recipients even when adaptive xenoimmune responses are suppressed. In addition to xenograft rejection by recipient innate immune cells, phagocytic cells within liver xenografts are also deleterious to recipients by causing thrombocytopenia. SUMMARY Strategies of overcoming innate immune responses are required for successful clinical xenotransplantation. In addition to developing better immunosuppressive and tolerance induction protocols, endeavors towards further genetic modifications of porcine source animals are ultimately important for successful clinical xenotransplantation.

Abstract
When they recognize a target cell, natural killer (NK) cells mount an attack to kill the target by exerting their cytotoxicity via the exocytosis of cytotoxic granules. Although the details of this process (which includes the movement of cytotoxic granules in the immune synapse and their fusion with the plasma membrane, releasing granzymes and perforin into the synaptic cleft) are relatively better understood, the post-exocytosis regulation of the process is still largely unknown. Here we show that a clathrin-dependent endocytosis stimulated by target cell occurs in NK92 cell line, which is closely correlated with granzyme B recovery. Inhibition of the endocytosis significantly attenuates the cytotoxicity of NK92 cells. The NK cell recovery of its released effector molecules, in turn, suggests that endocytosis may well play a key role in the post exocytosis regulation of immune cells.

Abstract
PURPOSE OF REVIEW Cellular human antipig immune responses are increasingly recognized as an important barrier to successful clinical xenotransplantation. This review addresses the role of monocytes/macrophages, natural killer (NK) cells, and T cells in xenograft rejection. We focus on the receptor-ligand interactions that regulate the responses of these cells to porcine tissues and thus could be targets for immunomodulation. RECENT FINDINGS Activation of human monocytes by pig cells is partly due to the incapacity of porcine ligands to bind to inhibitory receptors such as signal regulatory protein alpha. Porcine UL16-binding protein 1 can functionally interact with human NK group 2D protein, thereby contributing to human NK cell activity. Transgenic pigs overexpressing human leukocyte antigen class E were generated. Cells from these pigs induced diminished NK-cell lysis, suggesting that human leukocyte antigen class E expression compensates for the inability of porcine ligands to bind to the inhibitory CD94/NK group 2A receptor on human NK cells. A new concept for the modulation of antipig T-cell reactivity may result from the finding that porcine antigen-presenting cells that overexpress human negative costimulatory PD ligands also induce diminished responses of human T cells. SUMMARY Disruption of stimulatory receptor-ligand interactions (e.g. by blocking antibodies or 'knockout/down' technologies) combined with transgenic overexpression of inhibitory ligands in porcine cells and tissues could be an effective approach to downregulate human antipig cellular immune responses.

Abstract
Natural killer (NK) cells can destroy xenogeneic tissues by antibody-dependent cell cytotoxicity (ADCC) and direct lysis. Unlike ADCC, activating interactions between human NK receptors and their cognate ligands in pigs are not fully elucidated. We set up this study to identify human NK activating receptors recognizing porcine cells isolated from distinct organs, e.g., aorta, cornea and liver, and to provide a molecular basis for effective immunosuppressive regimens. Among the array of NK receptors tested, NKp46, 2B4, CD49d, CD48, CD2 and NKG2D, only CD2 and NKG2D were shown to be involved in both cytotoxicity and cytokine (interferon-gamma and tumour necrosis factor-alpha) production against porcine targets. Simultaneous blocking of CD2 and NKG2D by combining its monoclonal antibodies further suppressed xenogeneic NK responses. Moreover, addition of a suboptimal dose of PD98059, an extracellular signal-regulated kinase (ERK) kinase inhibitor, to those cells maximally reduced NK cytotoxicity, suggesting that ERK plays an important role in NK-mediated xenoreactivity. These impairments in NK cells were tightly associated with defective intracellular calcium mobilization and the subsequent degranulation process. Therefore, our data demonstrate a distinct role of CD2 and NKG2D on human NK cells in recognizing porcine grafts and further provide a potentially efficacious combinational regimen using anti-CD2 and anti-NKG2D monoclonal antibodies with PD98059 in a pig-to-human transplantation model.

Abstract
Xenotransplantation is one promising approach to bridge the gap between available human cells, tissues, and organs and the needs of patients with diabetes or end-stage organ failure. Based on recent progress using genetically modified source pigs, improving results with conventional and experimental immunosuppression, and expanded understanding of residual physiologic hurdles, xenotransplantation appears likely to be evaluated in clinical trials in the near future for some select applications. This review offers a comprehensive overview of known mechanisms of xenograft injury, a contemporary assessment of preclinical progress and residual barriers, and our opinions regarding where breakthroughs are likely to occur.
