Abstract
Allogeneic haematopoietic stem cell transplantation (HSCT) remains the only potential cure for intermediate to high-risk acute myeloid leukaemia (AML). The therapeutic effect of HSCT is largely dependent on the powerful donor-derived immune response against recipient leukaemia cells, known as graft-versus-leukaemia effect (GvL). However, the donor-derived immune system can also cause acute or chronic damage to normal recipient organs and tissues, in a process known as graft-versus-host disease (GvHD). GvHD is a leading cause of non-relapse mortality in HSCT recipients. There are many similarities and cross talk between the immune pathways of GvL and GvHD. Studies have demonstrated that both processes require the presence of mismatched alloantigens between the donor and recipient, and activation of immune responses centered around donor T-cells, which can be further modulated by various recipient or donor factors. Dissecting GvL from GvHD to achieve more effective GvHD prevention and enhanced GvL has been the holy grail of HSCT research. In this review, we focused on the key factors that contribute to the immune responses of GvL and GvHD, the effect on GvL with different GvHD prophylactic strategies, and the potential impact of various AML relapse prevention therapy or treatments on GvHD.

Abstract
Neuroblastoma represents a relatively common childhood tumor that imposes therapeutic difficulties. High risk neuroblastoma patients have poor prognosis, display limited response to radiochemotherapy and may be treated by hematopoietic cell transplantation. Allogeneic and haploidentical transplants have the distinct advantage of reinstitution of immune surveillance, reinforced by antigenic barriers. The key factors favorable to ignition of potent anti-tumor reactions are transition to adaptive immunity, recovery from lymphopenia and removal of inhibitory signals that inactivate immune cells at the local and systemic levels. Post-transplant immunomodulation may further foster anti-tumor reactivity, with positive but transient impact of infusions of lymphocytes and natural killer cells both from the donor, the recipient or third party. The most promising approaches include introduction of antigen-presenting cells in early post-transplant stages and neutralization of inhibitory signals. Further studies will likely shed light on the nature and actions of suppressor factors within tumor stroma and at the systemic level.

Stem Cell Res Ther 2018; 9:337. [PMID: 30526661 PMCID: PMC6286512 DOI: 10.1186/s13287-018-1080-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Revised: 11/12/2018] [Accepted: 11/19/2018] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND As the implantation and long-term existence of tumor-specific T cells in host are the prerequisite for adoptive immunotherapy, memory stem T cells (TSCM) with self-renewal and differentiation capacity show the greatest potential to implant and long-term exhibit function in vivo, compared with other T cells of differentiation stages. Hence, tumor-specific TSCM have become potential candidate for adoptive T cell therapy of cancer. Here, we reported a protocol to generate allogeneic antigen-specific CD8+ TSCM cells from human PBLs. METHODS To prepare allogeneic antigen-specific CD8+ TSCM, we used an LCL named E007 of defined HLA allotyping as simulator, a co-culture of E007 and allogeneic PBLs was carried out in the presence of differentiation inhibitor TWS119 for 7 days. Sorting of proliferation cells ensured the E007-specificity of the prepared TSCM cells. The sorted lymphocytes underwent further expansion by cytokines IL-7 and IL-15 for further 7 days, making the E007-specific CD8 + TSCM expanded in number. The stem cell and T memory cell properties of the prepared CD8+ TSCM were observed in NOD-SCID mice. RESULTS Our protocol began with 1 × 107 PBLs and resulted in 2 × 107 E007-specific CD8+ TSCM cells in 2 weeks of preparation. The prepared TSCM cells exhibited a proliferative history and rapid differentiation into effector cells upon the E007 re-stimulation. Importantly, the prepared TSCM cells were able to exist long and reconstitute other T cell subsets in vivo, eradicating the E007 cells effectively after transferred into the LCL burden mice. CONCLUSIONS This protocol was able to prepare allogeneic antigen-specific CD8+ TSCM cells from human PBLs. The prepared TSCM showed the properties of stem cells and T memory cells. This study provided a reference method for generation of antigen-specific TSCM for T cell adoptive immunotherapy.

Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplantation is a potentially curative therapy for many malignant and nonmalignant hematologic diseases. However, acute graft-versus-host disease (aGVHD) is a lethal complication of hematopoietic stem cell transplantation, which limits its application. Cytokines such as tumor necrosis factor-α and interleukin-6 play an extremely important role in the formation and development of aGVHD. Reactive oxygen species, such as hydroxyl radicals, also play an important role in the formation and development of aGVHD. In recent years, hydrogen was reported to have an ability to inhibit the levels of cytokines, such as tumor necrosis factor and interleukin-6 in vivo, and it also has a strong selective free radical-scavenging ability. Therefore, we hypothesized that hydrogen may have therapeutic effects on aGVHD. METHODS To determine whether hydrogen could protect mice from lethal GVHD in a major histocompatibility complex-incompatible murine bone marrow transplantation (BMT) model, survival rates of mice were calculated and leukocyte counts were also determined after BMT. We also examined serum cytokine levels and scored clinical signs of GVHD mice after BMT. RESULTS AND CONCLUSION This article demonstrated that the administration of hydrogen-rich saline increased the survival rate and clinical score of aGVHD mice. Administration of hydrogen-rich saline after transplantation also promoted the recovery of white blood cells of aGVHD mice. However, there was no report on the therapeutic effects of hydrogen on aGVHD. It is suggested that hydrogen has a potential as an effective and safe therapeutic agent on aGVHD.

Abstract
Generation of tumor specific alloreactive CD4(+) T cells is important to circumvent tumor tolerance. Here, we generate allorestricted peptide-specific CD4(+) T cells by coculture of lymphocytes and autologous monocytes bearing allogeneic HLA-DR15 molecule associated with its restricted peptide. Binding of a dimeric HLA-DR15/IgG1-Fc fusion protein (the dimer) to HLA-DR15 negative (HLA-DR15-ve) monocytes made the monocytes coated with the allogeneic epitope. An increased proliferation of CD4(+) T cells and induction of Th1 cells appeared after coculturing of HLA-DR15-ve lymphocytes and the autologous monocytes loaded with the dimer. The cocultural bulks showed an increased frequency of the specific dimer-stained CD4(+) T cells and the expanded CD4(+) T cells exhibited an elevated IFN-γ production in response to specific TCR ligand. Tumor rejection effects of the allorestricted E7-specific CD4(+) T cells raised by the coculture were observed in nude mice challenged with human cervical cancer cell SiHa expressing both HLA-DR15 and E7 antigens, as the tumor avoidance and life span of the mice were improved after adoptive transfer of the CD4(+) T cells. This study may help to develop strategies to separate graft-versus-leukemia or graft-versus-tumor reaction from graft-versus-host disease, and add to the pool of human high-avidity TCRs specific for tumor or virus antigens.

Abstract
The development of reduced intensity or non-myeloablative conditioning (NST) in preparation for allogeneic stem cell transplantation (SCT) revolutionized the field and led to reconsideration of the dogma of upper age limit that was set up by the transplant centers as an eligibility parameter. Analysis of the literature data showed that NST regimens are associated with decreased transplant related mortality, and graft-versus-host disease, in comparison with standard myeloablative conditioning, in patients above the age of 50-55 years, or in younger patients with significant comorbidities. However we have to mention, that our considerations are based on the retrospective analysis of the literature data, and that well controlled prospective randomized studies are needed in order to definitely assess the role of NST. Comorbidity indices might be proved as the most important parameters for the choice of the most proper regimen for each patient in need and should be included in future trials.

Abstract
We studied the oxidative status of red and white blood cells during the development of graft vs host disease (GVHD) as well as the effects of treatment with antioxidants, both in vitro and in vivo. (BALB/c X C57BL/6) F1 mice were conditioned by total body radiation and, 1 day later, transplanted with semi-allogeneic C57BL/6 spleen cells. GVHD was followed by its clinical manifestations. Oxidative stress in red blood cells (RBC), neutrophils, and lymphocytes was assessed by measuring generation of reactive oxygen species and the content of reduced glutathione by flow cytometry after gating of the specific populations. Oxidative stress was noticed 3 weeks after transplantation. It was higher in mice receiving allogeneic spleen cells as compared with mice transplanted with syngeneic cells, suggesting that it was associated with GVHD. The results also demonstrated that treatment with the antioxidants N-acetylcysteine and a derivative of vitamin E (tocopherol succinate, propofol), both in vitro and in vivo, reduced the oxidative stress. The results indicate that various blood cells, including RBC, neutrophils, and lymphocytes, are under oxidative stress and that treatment with antioxidants reduced the stress and, thus, may be useful in ameliorating the severe consequences of GVHD.
