Small hypoxia-primed mesenchymal stem cells attenuate graft-versus-host disease.

Project description:Mesenchymal stem cells (MSCs) are of particular interest for the treatment of immune-related diseases due to their immunosuppressive capacity. Here, we show that Small MSCs primed with Hypoxia and Calcium ions (SHC-MSCs) exhibit enhanced stemness and immunomodulatory functions for treating allogeneic conflicts. Compared with naïve cultured human umbilical cord blood-derived MSCs, SHC-MSCs were resistant to passage-dependent senescence mediated via the monocyte chemoattractant protein-1 and p53/p21 cascade and secreted large amounts of pro-angiogenic and immunomodulatory factors, resulting in suppression of T-cell proliferation. SHC-MSCs showed DNA demethylation in pluripotency, germline, and imprinted genes similarly to very small embryonic-like stem cells, suggesting a potential mutual relationship. Genome-wide DNA methylome and transcriptome analyses indicated that genes related to immune modulation, cell adhesion, and the cell cycle were up-regulated in SHC-MSCs. Particularly, polo-like kinase-1 (PLK1), zinc-finger protein-143, dehydrogenase/reductase-3, and friend-of-GATA2 play a key role in the beneficial effects of SHC-MSCs. Administration of SHC-MSCs or PLK1-overexpressing MSCs significantly ameliorated symptoms of graft-versus-host disease (GVHD) in a humanized mouse model, resulting in significantly improved survival, less weight loss, and reduced histopathologic injuries in GVHD target organs compared with naïve MSC-infused mice. Collectively, our findings suggest that SHC-MSCs can improve the clinical treatment of allogeneic conflicts, including GVHD.

Small sized mesenchymal stem-cells primed with hypoxia attenuate graft-versus-host disease [transcriptome dataset]

Project description:Mesenchymal stem-cells (MSCs) are of particular interest for treating immune-related diseases due to their immunosuppressive capacities. Here, we show that Small sized MSCs primed with Hypoxia and Calcium ion (SHC-MSCs) exhibit the enhanced functions regarding stemness and immunomodulation for treating allogeneic conflicts. Compared with naïve cultured human umbilical cord-blood MSCs, SHC-MSCs were resistant to the passage dependent cellular senescence mediated by MCP-1 and p53/p21 cascade and highly secreted the pro-angiogenic and immune-modulatory factors, resulting in suppression of T-cell proliferation. Genome-wide DNA methylome and transcriptome analysis indicate that SHC-MSCs characteristically up-regulated immune-modulation, cell adhesion and cell-cycle related genes. As downstream factors, PLK1, ZNF143, DHRS3, and FOG2 proteins played a key role on the beneficial effects of SHC-MSCs, evidenced by the promoted self-renewal, migration, pro-angiogenic, anti-inflammatory, and T cell suppression capacities in their-over-expressing MSCs. Importantly, administration of SHC-MSCs or PLK1-over-expressing cells (PLK1-MSCs) significantly reduced the symptoms of graft-versus-host disease (GVHD) in a humanized mouse model which led to significantly improved survival, less weight loss, and less histopathologic injuries of GVHD target organs compared with naive MSC-infused mice. Collectively, our study suggests that small-sized MSCs primed with hypoxia could advance the therapeutic strategy for the clinical treatment of allogeneic conflicts including GVHD.

Kras-Deficient T Cells Attenuate Graft-versus-Host Disease but Retain Graft-versus-Leukemia Activity.

Project description:Acute graft-versus-host disease (aGVHD) is one major serious complication that is induced by alloreactive donor T cells recognizing host Ags and limits the success of allogeneic hematopoietic stem cell transplantation. In the current studies, we identified a critical role of Kras in regulating alloreactive T cell function during aGVHD. Kras deletion in donor T cells dramatically reduced aGVHD mortality and severity in an MHC-mismatched allogeneic hematopoietic stem cell transplantation mouse model but largely maintained the antitumor capacity. Kras-deficient CD4 and CD8 T cells exhibited impaired TCR-induced activation of the ERK pathway. Kras deficiency altered TCR-induced gene expression profiles, including the reduced expression of various inflammatory cytokines and chemokines. Moreover, Kras deficiency inhibited IL-6-mediated Th17 cell differentiation and impaired IL-6-induced ERK activation and gene expression in CD4 T cells. These findings support Kras as a novel and effective therapeutic target for aGVHD.

Human amnion-derived mesenchymal stem cells attenuate xenogeneic graft-versus-host disease by preventing T cell activation and proliferation.

Project description:Acute graft-versus-host disease (GVHD) is characterized by severe tissue damage that is a life-threatening complication of allogeneic hematopoietic stem cell transplantation. Due to their immunosuppressive properties, mesenchymal stem cells (MSC) have been increasingly examined for the treatment of immune-related diseases. We aimed to assess the immunosuppressive effects of human amnion-derived MSC (AMSC) in a xenogeneic GVHD NOD/Shi-scid IL2rγnull mouse model using human peripheral blood mononuclear cells (PBMC). Additionally, we used human bone marrow-derived MSC (BMSC) as comparative controls to determine differences in immunomodulatory functions depending on the MSC origin. Administration of AMSC significantly prolonged survival, and reduced human tumor necrosis factor-α (TNF-α) concentration and percentage of programmed cell death protein-1 receptor (PD-1)+CD8+ T cell populations compared with in GVHD control mice. Furthermore, colonic inflammation score and percentage of human CD8+ T cell populations in AMSC-treated mice were significantly lower than in GVHD control and BMSC-treated mice. Interestingly, gene expression and protein secretion of the PD-1 ligands were higher in AMSC than in BMSC. These findings are the first to demonstrate that AMSC exhibit marked immunosuppression and delay acute GVHD progression by preventing T cell activation and proliferation via the PD-1 pathway.
