Acute respiratory distress syndrome (ARDS) is a crippling disease with no effective therapy characterized by progressive dyspnea. Mesenchymal stem cells (MSCs) have emerged as a new therapeutic modality for ARDS because MSCs can attenuate inflammation and repair the damaged tissue by differentiating into several cell types. Macrophages participate in the(More)
Macrophage infiltration of skin GVHD lesions correlates directly with disease severity, but the mechanisms underlying this relationship remain unclear and GVHD with many macrophages is a therapeutic challenge. Here, we characterize the macrophages involved in GVHD and report that dexamethasone palmitate (DP), a liposteroid, can ameliorate such GVHD by(More)
To study cow's milk allergy at the cellular level, we assessed the reactivity of peripheral blood mononuclear cells from patients allergic to cow's milk to alpha s1-casein, which is one of the major allergens in cow's milk. Proliferation of the cells to alpha s1-casein activation showed a rather weak response. Therefore to understand T-cell reactivity to(More)
We aimed to evaluate the impact of pretransplant imatinib administration on the outcome of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adults with Philadelphia chromosome-positive (Ph(+)) acute lymphoblastic leukemia (ALL). We retrospectively analyzed 738 patients with Ph(+) ALL that underwent allo-HSCT between 1990 and 2010 using data(More)
TP53 mutation is associated with various hematological malignancies and immunohistochemistry of p53 has been used as a simple method to establish the presence of a TP53 mutation. Since the significance of p53 expression is controversial in myelodysplastic syndrome (MDS) patients treated with azacitidine (Aza), we analyzed the prevalence of p53 expression as(More)
Hemophagocytic syndrome (HPS) induced by uncontrolled macrophage activation and subsequent graft failure is a frequent and prominent complication after allogeneic stem cell transplantation (allo-SCT), a cause of severe morbidity and death, and a therapeutic challenge. Liposome-incorporated dexamethasone, dexamethasone palmitate (DP), shows greater efficacy(More)
To evaluate the effect of post-transplant imatinib administration, 34 Philadelphia chromosome-positive acute lymphoblastic leukaemia (Ph(+)ALL) patients were retrospectively analysed, with 7 receiving post-transplant imatinib administration. Overall survival was significantly better in patients with post-transplant administration (66.7% vs. 29.6% at 3(More)
To identify factors to improve the outcomes of related and unrelated allogeneic stem cell transplantations (allo-SCT) for Philadelphia chromosome-negative acute lymphocytic leukemia (Ph(-) ALL) in the first complete remission (CR1), we retrospectively analyzed 1139 Ph(-) ALL patients using the registry data, particularly the details of 641 patients(More)
We retrospectively reviewed 104 biopsy specimens of previously untreated skin acute graft-versus-host disease (GVHD) within 100 days after allogeneic stem cell transplantation, and analyzed the relationship between types of infiltrating cells and clinical outcomes. Counting the total number of CD8(+) T cells, CD163(+) macrophages, and CD1a(+) dendritic(More)
