Individuals with acute myeloid leukemia (AML) harboring an internal tandem duplication (ITD) in the gene encoding Fms-related tyrosine kinase 3 (FLT3) who relapse after allogeneic hematopoietic cell transplantation (allo-HCT) have a 1-year survival rate below 20%. We observed that sorafenib, a multitargeted tyrosine kinase inhibitor, increased IL-15 production by FLT3-ITD leukemia cells. This synergized with the allogeneic CD8 T cell response, leading to long-term survival in six mouse models of FLT3-ITD AML. Sorafenib-related IL-15 production caused an increase in CD8CD107aIFN-γ T cells with features of longevity (high levels of Bcl-2 and reduced PD-1 levels), which eradicated leukemia in secondary recipients. Mechanistically, sorafenib reduced expression of the transcription factor ATF4, thereby blocking negative regulation of interferon regulatory factor 7 (IRF7) activation, which enhanced IL-15 transcription. Both IRF7 knockdown and ATF4 overexpression in leukemia cells antagonized ...

Extreme graft-versus-host disease (aGVHD) is the most common problem for individuals undergoing allogeneic come cell transplantation. the lethality of aGVHD and in dealing with lower GI system disease. ILC2 infusion was connected with decreased donor proinflammatory Th1 and Th17 852391-20-9 cells, build up of donor myeloid-derived suppressor cells (MDSCs) mediated by ILC2 creation of IL-13, improved GI system buffer function, and a maintained graft-versus-leukemia (GVL) response. Jointly, these results recommend that infusion of donor ILC2h to restore gastrointestinal system homeostasis may improve treatment of serious lower GI system aGVHD. Intro Allogeneic come cell transplant (allo-SCT) offers the potential to offer healing therapy for individuals with high-risk severe leukemia, lymphoid malignancies, and additional cancerous illnesses (1C3). Despite improvements in HLA keying in and come cell donor selection, graft-versus-host disease (GVHD) continues to be the main problem of allo-SCT, with ...

In HSCT, the natural alloreactivity of donor T lymphocytes play a major role in the eradication of the underlying malignant disease in the so-called GVL effect1. However, the majority of alloantigens are not only expressed by leukemic cells, but also by normal cells. The GVL effect is therefore often accompanied by an alloimmune attack against healthy tissues, whose manifestations are known as GVHD. GVHD is a severe disease that is often lethal. GvHD prevention is accomplished through either T-cell depletion of the graft or post-transplant immune suppression. Although effective in abating GVHD incidence and severity, both strategies unfortunately associate with a significant reduction in the GVL effect, thus jeopardizing the overall efficacy of HSCT.. Alternatively to avoiding alloreactivity tout-court, suicide gene therapy proposes to exploit the GVL effect, while having the possibility to switch off GVHD at will2. This goal is achieved through the ex vivo genetic modification of T lymphocytes ...

Allogeneic immune cells, particularly T cells in donor grafts, recognize and eliminate leukemic cells via graft-versus-leukemia (GVL) reactivity, and transfer of these cells is often used for high-risk hematological malignancies, including acute myeloid leukemia. Unfortunately, these cells also attack host normal tissues through the often fatal graft-versus-host disease (GVHD). Full separation of GVL activity from GVHD has yet to be achieved. Here, we show that, in mice and humans, a population of interleukin-9 (IL-9)-producing T cells activated via the ST2-IL-33 pathway (T9IL-33 cells) increases GVL while decreasing GVHD through two opposing mechanisms: protection from fatal immunity by amphiregulin expression and augmentation of antileukemic activity compared with T9, T1, and unmanipulated T cells through CD8α expression ...

Successful prevention of post-transplantation relapse after donor lymphocyte infusion (DLI) depends on its capability to mediate an effective graft-versus-leukemia (GVL) response while minimizing DLI-related toxicity, including graft-versus-host disease (GVHD). We assessed the effects of decitabine (DEC), a hypomethylating agent, upon allogeneic immune reaction in a murine model of DLI. Significantly greater tumor growth retardation and survival prolongation occurred in mice administered with 1.0 mg/kg DEC for 5 days (DEC-1.0) than in control or DEC-0.1 mice. Upon prompt DEC and DLI co-administration, dendritic cells (DCs) were activated; DEC-1.0/DLI induced severe GVHD, and survival was significantly lower than with DLI alone or DEC-0.1/DLI treatments. IFN-γ and CD28 levels were higher in splenic DCs of DEC-1.0 mice than in those of control mice. Assessment of delayed DLI co-administration with DEC, when IFN-γ levels were normalized to control levels, revealed that DEC-1.0/DLI successfully

Although an increasing number of MiHA in different HLA molecules have been identified in the last decades, the number of MiHA with therapeutic relevance is still limited.3-7 We previously demonstrated induction of CD8+ T cells specific for hematopoietic restricted MiHA HA-1 and HA-2 in a patient who developed a strong GvL response with limited GvHD of the skin after treatment with DLI for relapsed CML more than one year after HLA-matched alloSCT.13 We also isolated CD4+ T cells from this patient, and showed recognition of 6 HLA class II associated MiHA, of which 5 MiHA have been identified by screening a recombinant bacteria cDNA library.15,17 In this report, we demonstrated that in addition to HA-1 and HA-2, which are both presented by HLA-A*02:01, CD8+ T cells were induced against 4 MiHA in HLA-B*40:01 and one MiHA in HLA-B*08:01, illustrating the diversity of MiHA targeted in this GvL response. The HLA-B*40:01 restricted MiHA were identified by screening a plasmid cDNA expression library and ...

MUSC Hollings Cancer Center researchers identified that blocking an alternative energy pathway for T-cells after hematopoietic stem cell transplant helps reduce graft-versus-host disease (GVHD) in an animal model of leukemia. Xue-Zhong Yu, M.D., who also is associate director of Basic Science at Hollings, and collaborators at the Indiana University School of Medicine discovered that donor T-cells must have the key enzyme lysosomal acid lipase in order to induce GVHD.. The Yu laboratory focuses on understanding the biological balance between GVHD and graft-versus-leukemia effect. Hematopoietic stem cell transplantation is used as a treatment option for some leukemia patients. T-cells in stem cell grafts from a donor are given to a leukemia patient in order to kill the cancer and reboot the patients immune system. GVHD is a big clinical challenge because the donor T-cells, which come from the bone marrow, can attack the patients organs. Anywhere from 30% to 70% of patients develop acute GVHD ...

The primacy of the gastrointestinal (GI) tract in dictating the outcome of graft-versus-host disease (GVHD) is broadly accepted; nevertheless, the mechanisms managing this effect are understood poorly. on donor Testosterone levels cells, leading to their emigration into the GI system where they mediate fulminant disease. These data recognize a vital, distinct anatomically, donor DC subset that amplifies GVHD. We showcase multiple healing goals and the capability of GVHD hence, once started by receiver antigen-presenting cells, to generate a unique, localised, and lethal feed-forward cascade of donor DCCmediated indirect alloantigen cytokine and GBR-12909 display release within the GI system. Allogeneic hematopoietic control cell transplantation is certainly a therapy for hematopoietic malignancies in which treat is certainly attained by immune-mediated graft-versus-leukemia (GVL) results. Graft-versus-host disease (GVHD) is certainly a equivalent procedure whereby regular tissues, especially ...

Dr McGee is referring Tyler back to SCCA for testing and possible treatment. Most likely, Tyler would get a Donor Lymphomcyte Infusion. This is like a booster shot of white blood cells from his father, that should stimulate the marrow to attack the leukemia cells that are floating around in there. The goal of this treatment is to get Tyler back into full remission, but would likely cause a recurrence and possibly an increase in Tylers Graft vs Host (GVHD) symptoms, but would also increase the Graft vs. Leukemia effect (beneficial). I know this all sounds very complicated, but we are working through this and finding out about the procedure ...

Patients with leukemia who receive a T cell-depleted allogeneic stem cell graft followed by postponed donor lymphocyte infusion (DLI) can experience graft-versus-leukemia (GVL) reactivity, with a lower risk of graft-versus-host disease (GVHD). Here, we have investigated the magnitude, diversity, and specificity of alloreactive CD8 T cells in patients who developed GVL reactivity after DLI in the absence or presence of GVHD. We observed a lower magnitude and diversity of CD8 T cells for minor histocompatibility antigens (MiHAs) in patients with selective GVL reactivity without GVHD. Furthermore, we demonstrated that MiHA-specific T cell clones from patients with selective GVL reactivity showed lower reactivity against nonhematopoietic cells, even when pretreated with inflammatory cytokines. Expression analysis of MiHA-encoding genes showed that similar types of antigens were recognized in both patient groups, but in patients who developed GVHD, T cell reactivity was skewed to target broadly ...

The graft-versus-leukemia (GVL) effect in allogeneic hematopoietic stem cell transplantation (alloSCT) is potent against chronic phase chronic myelogenous leukemia (CP-CML), but blast crisis CML (BC-CML) and acute myeloid leukemias (AML) are GVL resistant. To understand GVL resistance, we studied GVL against mouse models of CP-CML, BC-CML, and AML generated by the transduction of mouse BM with fusion cDNAs derived from human leukemias. Prior work has shown that CD4+ T cell-mediated GVL against CP-CML and BC-CML required intact leukemia MHCII; however, stem cells from both leukemias were MHCII negative. Here, we show that CP-CML, BC-CML, and AML stem cells upregulate MHCII in alloSCT recipients. Using gene-deficient leukemias, we determined that BC-CML and AML MHC upregulation required IFN-γ stimulation, whereas CP-CML MHC upregulation was independent of both the IFN-γ receptor (IFN-γR) and the IFN-γ/γ receptor IFNAR1. Importantly, IFN-γR-deficient BC-CML and AML were completely resistant ...

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is an established and powerful treatment modality for patients with multiple hematological malignancies and inborn errors. In particular, the immunotherapeutic effect, known as the graft versus leukemia (GVL) effect, significantly reduces the rate of relapse in leukemia patients, receiving their allograft as consolidation therapy in first or subsequent remission However, GVL is strongly associated with the occurrence of acute and/or chronic graft versus host disease (GVHD). GVHD occurs in 35%-50% of the transplanted patients, still substantially limiting the outcome and the more widespread use of allo-SCT .Thus, allo-SCT strategies which separate GVHD from GVL effects and therapies which treat effectively GVHD are urgently needed. The core of acute GVHD treatment consists of immunosuppression, with 1-2mg/kg/d prednisolone as the standard first line treatment. Several studies demonstrate an overall complete response rate to ...

Our group is interested in understanding the biology of immune responses following allogeneic haematopoietic stem cell transplantation (allo-HSCT). Graft-versus-host disease (GVHD) is a major clinical problem and is caused by donor T cells within the graft that recognize antigens found in the patient but not the donor. Following allo-HSCT, activated donor T cells are recruited to peripheral organs where they cause severe injury, for example colitis or dermatitis. A similar immune reaction can occur in the lymphoid organs and bone marrow, a process co-opted therapeutically to achieve a graft-versus-leukaemia (GVL) effect. Although GVL can be separated from GVHD in experimental models, few of the identified strategies have been successfully translated into clinical practice. This failure reflects considerable redundancy in the mechanisms leading to GVHD and a lack of whole system approaches that readily address the complexity of this disorder ...

Bone marrow transplantation, or allogeneic hematopoietic stem cell transplant (HCT), is the only curative therapy for many patients with leukemia. Certain immune cells, called T cells, contained in the donor HCT graft can cause a graft versus leukemia (GVL) effect which eliminates leukemic cells. Unfortunately, there are also donor T cells in the HCT graft that can cause a condition called graft versus host disease (GVHD). GVHD is a life-threatening immune response that remains the major barrier to the success of transplantation. Dr. ...

We have previously shown that Kb-restricted and peptide-specific CTLs can be detected among BALB/c splenocytes. Such cells were very rare and were obscured by many alloreactive cells recognizing the target cells in a peptide-independent manner. We had to deplete such cells in order to generate several peptide-specific CTL lines (27). Similar protocols have been successfully used to deplete graft-versus-host activity without compromising the graft-versus-leukemia effect of allogeneic PBLs in bone marrow transplantation (35)(36)(37). However, since we (data not shown) and others (38) had difficulty generating allorestricted CTLs against individual peptides when CTLs and target cells were completely allogeneic to each other, we wished to analyze the spectrum of CTL precursors specific for allogeneic MHC-peptide complexes in closely related versus unrelated MHC combinations. Our results show that an alloresponse against a related MHC molecule contains more peptide-specific T cells than a response ...

Organic killer (NK) cells mediate GVL effects after allogeneic hematopoietic cell transplantation (allo-HCT) by the production of inflammatory cytokines and by direct target lysis. suppression showed diminished NK cell degranulation. In contrast degranulation was normal or increased after T-cell replete transplants given with immune suppression. Strikingly target cell-induced IFNγ production was markedly reduced in every transplant settings specifically with T cell-depleted or naive T cell-containing umbilical cable blood grafts recommending a job for T cells in NK education. Although degranulation was equivalent in the KIR and KIR+? populations that coexpressed NKG2A focus on cell-induced IFNγ creation was limited by the subset of NK cells expressing KIR inhibited by self-ligands. Hence cytokine production and cytotoxic function usually do not coexist in NK cells reconstituting following allo-HCT consistently.
