Abstract Abstract 1907 Defining in vivo effects and biodistribution of human bone marrow-derived mesenchymal stem cell (hMSCs) following allogeneic bone marrow transplantation (alloBMT) could impact the clinical utility of MSC therapy for the prevention and treatment of graft-versus-host disease (GvHD). Using an established model of murine alloBMT, we defined hMSC effects on GvHD and graft-versus-leukemia (GvL) activity. We first studied whether hMSC could modulate in vitro murine T-cell (TC) alloreactivity in mixed leukocyte cultures (MLCs). Specifically, hMSCs added to MLCs significantly reduced TC proliferation in a concentration-dependent manner distinct from human fibroblasts. In contrast to MLC cultures alone, MLCs containing hMSCs had significant reduction in TNFα, IFNγ, and IL-10 levels and higher levels of PGE2 and TGFβ1. Modulation in the inflammatory milieu was associated with changes in TC phenotypes, including more naïve and less activated TC surface marker expression (CD62L+CD69−) and the induction of CD4+CD25+FoxP3+ T-regulatory cells. To determine whether hMSCs could modulate in vivo mTC alloreactivity, irradiated recipient B6D2F1 (H-2bxd) mice were transplanted with allogeneic C57BL/6 (H-2b) BM and purified splenic TCs (B6→B6D2F1) and then were tail-vein injected with hMSC infusions (1 million per injection) on days one and four post-transplant. Syngeneic transplant recipients (B6D2F1→B6D2F1) were used as controls. hMSC-treated alloBMT mice had significantly prolonged survival and improved clinical GvHD scores, reduced splenic TC expansion and TNFα and IFNγ-producing TCs, and lower circulating TNFα and IFNγ levels versus untreated alloBMT mice. Bioluminescence imaging showed redistribution of labeled hMSCs from the lungs to abdominal organs within 72 hours following infusion. Importantly, GvHD target tissues (small and large bowel and liver) harvested from hMSC-treated alloBMT mice had significantly lower GvHD pathology scores than untreated alloBMT mice. We next determined the effects of hMSCs on GvL activity using the murine mastocytoma cell line, P815 (H-2d). TCs co-cultured with hMSCs maintained potent in vitro cytotoxic T-lymphocyte (CTL) activity comparable to untreated control CTLs. After challenge with P815 tumor cells, hMSCs-treated alloBMT mice had less severe GvHD, eradication of tumor burden, and improved leukemia-free survival compared to alloBMT control mice. Lastly, indomethacin (IM) added to MLC-hMSC co-cultures significantly reversed attenuation in both murine TC alloreactivity and surface activation expression. In addition, IM administered to hMSC-treated alloBMT mice reversed hMSC-associated survival advantage, suggesting that PGE2 in part mediates hMSC immunomodulatory effects. Together, our results show that hMSC infusions effectively attenuate GvHD and maintain GvL potency in alloBMT mice and reveal potential biomarkers and mechanisms of action underlying hMSC effects.

Graft Versus Leukemia

Allogeneic bone marrow transplantation (allo-BMT) is associated with both graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) effect. In the present study, we examined the contribution of cytotoxic effector mechanisms, which are mediated by tumor necrosis factor- (TNF-), Fas ligand (FasL), or perforin, to GVHD and GVL effect in a murine BMT model. Bone marrow cells plus spleen cells (BMS) from wild-type, FasL-defective, or perforin-deficient donors were transferred into lethally irradiated recipients in the parent (C57BL/6) to F1 (C57BL/6 × DBA/2) BMT model with or without prior inoculation of DBA/2 leukemia L1210 or P815 mast cytoma cells. The effect of anti–TNF- antibody administration was also examined. Whereas the defect or blockade of each cytotoxic pathway could ameliorate lethal acute GVHD, the GVL effect was differentially affected. The wild-type BMS recipients died of acute GVHD within 50 days without residual leukemia cells. The FasL-defective BMS recipients showed 60%< survival over 80 days without acute GVHD or residual leukemia cells. Administration of anti–TNF- antibody resulted in early leukemia relapse and the recipients died within 25 days with massive leukemia infiltration in the liver. The perforin-deficient BMS recipients died within 60 days with residual leukemia cells. These results suggest that blockade of the Fas/FasL pathway could be used for ameliorating GVHD without impairing GVL effect in allo-BMT.

Abstract We describe herein a case of nephrotic syndrome (NS) following allogeneic bone marrow transplantation (allo-BMT) for natural killer cell leukemia/lymphoma. Histologic studies defined the diagnosis as crescentic glomerulonephritis with massive immunoglobulin A (IgA) deposition, which has never been reported in NS cases following allo-BMT. Most of the massive infiltrated cells in the interstice were CD3+CD4−CD8+ T cells derived from the donor. We observed mesangial deposition of Haemophilus parainfluenza outer membrane (OMHP) antigen and decreased glycosylation of the IgA1 hinge in the recipient's samples is consistent with the recently reported pathogenesis of IgA nephropathy. Further, the titer of IgA antibody against the donor serum was as high as other IgA nephropathy cases. These findings suggest that NS and crescentic glomerulonephritis in this case occurred as one of the forms of chronic graft-versus-host disease (GVHD), and that IgA deposition was associated with H parainfluenza and decreased glycosylation of the IgA1 hinge.

Abstract Abstract: [Objective] Allogeneic bone marrow transplantation (allo-BMT) has been used for the treatment of refractory leukemia and donor lymphocyte infusion (DLI) was used for the purpose of graft versus leukemia (GVL) effects. However, DLI is associated with a risk of graft versus host disease (GVHD). Thus, new cellular-based methods are desired. In the present study, we performed thymus transplantation (TT) plus allo-BMT to explore it’s anti leukemia effects. [Methods] Recipient B6 mice (H-2b) bearing leukemia (EL-4 cells, H-2b) were irradiated 8 Gy. The next day, bone marrow cells from BALB/c mice (H-2d) were transplanted into the B6 mice. Simultaneously, DLI and thymus transplantation from the same donor were carried out. The survival period of the recipient B6 mice were examined, histological studies were performed in the liver, intestine, and the engrafted thymus from the recipients 4 weeks after the BMT. Surface markers on lymphocytes from the spleen were analyzed by 3-color fluorescence staining using a FACScan system to determine chimerism. [Results]. All mice treated with BMT showed fully donor-derived chimerism(H-2d). The survival rate in mice treated with BMT plus TT was significantly prolonged compared with those treated with BMT alone or BMT plus DLI. Histologically, both the cortex and medullar areas of the engrafted thymus under the renal capsule were clearly shown. Normal T-cell differentiation was also observed in the engrafted thymus. Microscopic founding of small intestine and liver in the BMT plus TT group indicated mild GVHD, whereas those treated with BMT plus DLI showed moderated to serious GVHD. The number of the CD4+ cells was significantly greater in the mice treated with BMT+TT compared with those with BMT alone or those with BMT + DLI. The percentage of FoxP3+ regulatory T cells among CD4+ cells was higher in the mice treated with BMT + TT comparable to those treated with BMT + DLI. The results for CD8+ T cells were similar to those for CD4+ cells. [Conclusion]. Allo-BMT combined with TT induces high thymopoiesis, and can elicit strong GVL effects with mild GVHD reaction. We thus found that donor-derived T cells play an important role in the treatment of leukemia. Also the details of the mechanisms are still unknown, one possibilities may be the continuous supplementation of T cells from the allogeneic thymus. The results of the present study suggest this strategy will become a new way for the treatment of refractory or relapse leukemia in human. Disclosures No relevant conflicts of interest to declare.
