Induction of regulatory M2 macrophage-like immunosuppressive cells from mouse ES cells that contribute to prolong allogeneic immune rejection

ABSTRACT: A promise of cell replacement therapy using pluripotent stem cells (PSCs) such as embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs) as donor source has been increased. However, particularly when ESCs were used, immune suppression should be required because the donor-recipient combination would be allogeneic. In this study, we examined a concept that some immunosuppressive cells could be induced from PSCs and those cells could prevent allogeneic immune rejection of the PSCs-based transplantation. In fact, we successfully induced immunosuppressive cells that resemble M2 macrophages in terms of cell surface molecule and gene expressions. They efficiently suppressed allogeneic T cell proliferative responses, at least partly, in nitric oxide dependent manner. We applied these cells to in vivoallogeneic transplantation and found that they substantially prolonged ESCs-derived graft survival. These results open a new insight for development of a practical immune-regulatory strategy in cell replacement therapy using PSCs.

Difference of the gene expression between ESdSC and ESdDC was analyzed. Two independent experiment were performed.

Murine regulatory T cells stimulated by death receptor 3 agonistic antibody

Project description:CD4+Foxp3+ regulatory T cells (Treg) are a subpopulation of T cells, which regulate the immune system and enhance immune tolerance after transplantation. Donor-derived Treg prevent the development of lethal acute graft and host disease (GVHD) in murine models of allogeneic hematopoietic cell transplantation. It was reported that a single treatment of the agonistic antibody to Death receptor 3 (DR3) in donor mice resulted in the expansion of donor derived Treg and prevented acute GVHD, although the precise role of DR3 signaling in GVHD has not been elucidated. We analyzed the gene expression profile, immune phenotype, and function of DR3-activated Treg in a murine model of allogeneic hematopoietic cell transplantation. CD4+Foxp3+ Treg were sorted from the mice stimulated with anti-DR3 or control antibody using fluorescence-activated cell sorter for RNA extraction and hybridization on Affymetrix microarrays.

Tolerant and rejecting T cell microarray

Project description:anti-CD4, CD8 and CD40L treated versus control murine CD4+ T cells from micegrafted with hESC derived xenografts. Human embryonic stem cells (ESCs), by virtue of their capability to self-renew and differentiate into almost all body cell types, represent the first type of pluripotent stem cells (PSCs) to be used in clinical transplantation to humans in recent phase-I trials. As it is unlikely that any such cells or their progeny will survive in an allogeneic host, there is an urgent need to understand how to get long-term acceptance and functional differentiation with minimal immunosuppression. Here, we show that brief induction with combined monoclonal antibody-mediated coreceptor and costimulation blockade enables long-term survival and engraftment of murine ESCs, human ESCs, human induced PSCs, and human ESC-derived progenitor cells from all three embryonic germ layers. Tolerance induced to PSC-derived progenitors appears, remarkably, to extend to protection of their differentiated progenies, and sometimes even to different tissues derived from the same donor, suggesting linked-suppression as a likely operative mechanism. These results suggest that once tolerance has been established to PSC-derived progenitor cells, it can be extended to their differentiated progenies. Global gene expression profiling of graft infiltrating T-lymphocytes identifies gene sets that differ between rejecting and tolerant populations including gene upregulation in pathways associated with apoptosis, cell adhesion, transcription suppression and TGF synthesis; and gene downregulation in pathways associated with inflammation in recipients treated with combined coreceptor and costimulation blockade. Mice grafted with hESC derived tissues and untreated (control) or tolerised via injections of anti-CD4, anti CD8 and CD40L. CD3+ T cells isolated from the gratfs 30 days later.

Donor T cells in ovarian graft versus host disease

Project description:Analysis of donor CD4+ and CD8+ T cells purified from spleens and ovaries after murine syngeneic and allogeneic hematopoietic stem cell transplantation Infertility associated with ovarian failure is a serious late complication for female survivors of allogeneic hematopoietic stem cell transplantation (SCT). While the role of pretransplant conditioning regimen has been well appreciated, increasing application of reduced-intensity conditioning facilitated us to revisit the other factors possibly affecting ovarian function after allogeneic SCT. We have addressed whether donor T-cell mediated graft-versus-host disease (GVHD) could be causally related to female infertility in mice. To study transcriptomes of donor T cells infiltrating into the ovary, donor T cells were sorted from recipients' ovaries and microarray analysis was performed.

Cyclophosphamide for Prevention of Graft-Versus-Host Disease After Allogeneic Peripheral Blood Stem Cell Transplantation in Patients With Hematological Malignancies

Project description:This phase II trial studies how well cyclophosphamide works in preventing chronic graft-versus-host disease after allogeneic peripheral blood stem cell transplant in patients with hematological malignancies. Giving chemotherapy and total-body irradiation before transplantation helps stop the growth of cancer cells and prevents the patient’s immune system from rejecting the donor’s stem cells. Healthy stem cells from a donor that are infused into the patient help the patient’s bone marrow make blood cells; red blood cells, white blood cells, and platelets. Sometimes, however, the transplanted donor cells can cause an immune response against the body’s normal cells, which is called graft-versus-host disease (GVHD). Giving cyclophosphamide after transplant may prevent this from happening or may make chronic GVHD less severe.

Donor Macrophages Modulate Rejection after Heart Transplantation

Project description:Cellular rejection after heart transplantation imparts significant morbidity and mortality. Current immunosuppressive strategies are imperfect, target recipient T-cells, and have adverse effects. The innate immune response plays an essential role in the recruitment and activation of T-cells. Targeting the donor innate immune response would represent the earliest interventional opportunity within the immune response cascade. There is limited knowledge regarding donor immune cell types and functions in the setting of cardiac transplantation and no current therapeutics exist for targeting these cell populations. Distinct populations of donor and recipient macrophages co-exist within the transplanted heart. Donor CCR2+ macrophages are key mediators of allograft rejection and deletion of MYD88 signaling in donor macrophages is sufficient to suppress rejection and extend allograft survival. This highlights the therapeutic potential of donor heart-based interventions.

Induced expression of PD-L1 in spermatogonial stem cells by self-renewal division allows allogeneic offspring production [Sequencing]

Project description:Testis immune privilege is thought to be mediated by somatic cells. However, it is not strong enough to protect allogeneic spermatogonial stem cells (SSCs) transplanted into the seminiferous tubules. Here we report successful production of allogeneic offspring by inducing PD-L1 in SSCs. Activation of self-renewal division induced PD-L1 and B7-H3 expression in cultured SSCs, which produced sperm after allogeneic transplantation. While B7-H3 depletion did not influence colonization, PD-L1 depletion prevented donor-derived spermatogenesis. PD-L1 expression was induced by BCL6B via reactive oxygen species (ROS) generation, suggesting that self-renewal stimulation confers immune privilege by ROS. In contrast, reduced ROS or Mapk14 deficiency downregulated PD-L1 expression. Allogeneic offspring were produced by SSC transplantation into congenitally infertile mice and busulfan-treated wild-type mice. Therefore, SSCs can escape rejection when their self-renewal division is stimulated.
