T-cell dysregulation and T-cell-related cytokine abnormalities are involved in the pathogenesis of immune thrombocytopenia (ITP). One of our previous studies showed that elevated IL-22 correlated to Th1 and Th22 cells plays an important role in the immunopathogenesis of ITP. In this study, we aimed to investigate the effects of high-dose dexamethasone(More)
OBJECTIVE To explore the functions of TH17 cell in cutaneous graft-versus-host disease (GVHD). METHODS A model of acute GVHD (aGVHD) was established with a major histocompatibility complex class I/II-disparate allogeneic bone marrow transplantation (BMT). Bone marrow monocytes and splenic T cells from donor C57/BL6 were enriched. The recipient BABL mice(More)
Acute graft-versus-host disease (aGVHD) has become the important complication post-allogeneic hematopoietic stem cell transplantation. Abnormally activated T cells might play an important role in the pathogenesis of aGVHD. But its exact mechanism remains poorly understood. T cell immune response cDNA 7 (TIRC7) has been identified to be essential in T cell(More)
β-Catenin is a key regulator of leukemia stem cell maintenance and drug resistance. Herein, we investigated the protective effects of the stromal cell-mediated VE-cadherin-β-catenin signal on Ph+ leukemia cells during imatinib treatment. We found stromal cells could desensitize imatinib and up-regulate VE-cadherin expression on Ph+ leukemia cells (K562 and(More)
OBJECTIVE To compare the efficacy and safety of low-dose rituximab combined with different dosage of glucocorticoids for immune thrombocytopenia (ITP). METHODS Seventy-four patients (35 male, median age 34 years, range 18-70 years) including 60 newly-diagnosed, 6 persistent, 5 chronic and 3 refractory patients were enrolled in this study, and separated(More)
The aim of study was to investigate the injury of bone marrow microenvironment after γ ray irradiation conditioning in mouse allogeneic hematopoietic stem cell transplantation (allo-HSCT). The mononuclear cells collected from mice bone marrow for culture in vitro, were identified by flow cytometry with double staining when cultured for 5 - 7 days. Mice were(More)
OBJECTIVE To investigate the effects of conditioning regimen on mice liver injury during hematopoietic stem cell transplantation. METHODS Forty healthy 8-10 weeks old female BALB/c mice were randomly divided into control group, non-myeloablative total body irradiation group, myeloablative total body irradiation group, busulfan group and cyclophosphamide(More)
OBJECTIVE To investigate the effect of allo-HSCT irradiation preconditioning on the homing of donor endothelial progenitor cells (EPCs). METHODS The mononuclear cells were collected form mice bone morrows, then cultured in EGM-2 medium. The cells were identified after 5-7 days and were labeled with CFSE. The mice were divided randomly into four groups,(More)
Numerous previous studies have suggested that cytotoxic T lymphocyte antigen-4 (CTLA-4) plays an important role in acute graft-versus-host disease (GVHD). How CTLA-4 acts in regulating acute GVHD remains unknown, however. In the present study, we found that, compared with healthy controls, CTLA-4 plasma and relative mRNA levels in patients with acute GVHD(More)
OBJECTIVE To investigate the proliferation of mouse splenic lymphocytes after shRNA mediated BTLA gene silence. METHODS Three specific shRNAs and one nonspecific shRNA (scrambled) were ligated to pSilencer3.1-H1-neo plasmid and then subcloned into lentiviral vector pLB. Recombinant viral particles were harvested post-transduction to 293T cells. Mouse(More)
