Project description:In comparison with allogeneic hematopoietic stem cell transplantation using other sources, umbilical cord blood transplantation (UCBT) offers substantial clinical advantages including a lower incidence and severity of acute graft-versus-host disease (GVHD) despite the use of allogeneic UCB stem cells with more disparate HLA. However, detailed pathophysiology of acute GVHD developed after UCBT has not yet been clarified. Here, we examined the roles of inflammatory cells in the pathogenesis of acute GVHD following UCBT, by expression profiling of a total of 615 genes in each of 4 subsets (CD4+, CD8+, CD14+, and CD56+) of peripheral blood mononuclear cells (PBMCs), which were taken from 5 patients with hematologic malignancy, in whom acute GVHD had developed after UCBT. By comparing expression profiles measured during acute GVHD with those measured upon discharge (recovery phase), for each subset of PBMCs, we identified immuno-regulatory genes which were assumed to be linked to the pathogenesis of acute GVHD. Keywords: disease state analysis CD4+, CD8+, CD14+, and CD56+ cell subsets were isolated from the peripheral blood mononuclear cells (PBMCs) of 5 patients with hematologic malignancy, in whom acute GVHD had developed after cord blood transplantation. PBMCs were taken twice â during acute GVHD phase and upon discharge (recovery phase), from each patient. By using a custom-made fibrous oligonucleotide DNA microarray Genopal (Mitsubishi Rayon), we compared expression profiles of 615 unique genes measured during acute GVHD with those measured upon discharge (recovery phase), for each subset of PBMCs.

Here, we examined the roles of inflammatory cells in the pathogenesis of acute GVHD following UCBT, by expression profiling of a total of 595 genes in each of 4 subsets (CD4+, CD8+, CD14+, and CD56+) of peripheral blood mononuclear cells (PBMCs), which were taken from 3 patients with hematologic malignancy, in whom acute GVHD had developed after UCBT. We compared expression profiles measured during acute GVHD with those measured opon discharge (recovery phase), for each subset of PBMCs to identify immuno-regulatory genes which were assumed to be linked to the pathogenesis of acute GVHD. Keywords: disease state analysis Peripheral blood mononuclear cells (PBMCs) were taken from 3 patients with hematologic malignancy, in whom acute GVHD had developed after cord blood transplantation. CD4+, CD8+, CD14+, and CD56+ cell subsets were isolated from the PBMCs of 2 patients, while only CD8+ and CD56+ cell subsets were isolated from the PBMCs of a patient. PBMCs were taken twice - during acute GVHD phase and upon discharge (recovery phase), from each patient.

Project description:The aim of this study is to assess the Fecal Microbiota Transplantation (FMT) efficacy in the prevention of allogeneic hematopoietic stem cell transplantation (allo-HSCT) complications and particularly Graft versus Host Disease (GvHD).
The hypothesis of this study is that allogeneic FMT may improve outcomes of these patients.

Project description:We obtained and collected PBMCs from patients with acute GVHD (aGVHD) and non-GVHD patients who did not develop aGVHD after HSPC transplantation, provided by Asan Medical Center. To understand the effect of NGO on aGVHD/nonGVHD patient's PBMCs, we treated PBMCs with NGO and analyzed changes in the transcriptome.

Project description:Allogeneic hematopoietic stem cell transplantation (HSCT) is the treatment of choice for high-risk hematological malignancies, yet a major complication associated with this therapy is acute graft-versus-host disease (GVHD). Despite a well-defined pathophysiological mechanism, there are no definitive markers for predicting acute GVHD development or progression to advanced stages. In the current study, we enrolled four acute GVHD and four acute GVHD-free recipients of allogeneic HSCT and collected peripheral blood just prior to onset of clinical acute GVHD for analysis on Affymetrix GeneChip Human Genome U133 Plus 2.0 microarrays. We noted significant differences in expression of 1,658 genes between control and acute GVHD patients, based on an analysis of covariance (ANCOVA) by type of transplant, a pooled error estimate, and a false discovery rate (FDR) of 10%. In conclusion, we offer the first report of a preliminary molecular signature of acute GVHD in allogeneic HSCT patients.

Project description:Graft-versus-host disease (GvHD) is still one of the major complications following allogeneic stem cell transplantation (SCT) triggered by alloreactive donor T cells. Whereas murine data have clearly shown the beneficial effects of regulatory T cells (Tregs) on the development of GvHD, data from the human system are rare mainly due to low cell numbers of circulating or organ-infiltrating Tregs in lymphopenic patients. Here, we present a comparative analysis of Tregs from patients with and without acute/ chronic GvHD designed as a dynamical approach studying the whole genome profile over the first 6 months after SCT. For this purpose, blood samples were collected monthly for FACS-based isolation of CD4+CD25highCD127low/- Tregs. The Treg transcriptome showed a high stability in the first half year representing the most sensitive time window for tolerance induction. However, the comparison of the Treg transcriptome from patients with and without GvHD uncovered regulated gene transcripts that point to a reduced suppressive function of Tregs with diminished migration capacity to the target organs likely contributing to the development of GvHD. These findings highlight the critical role of human Tregs in the pathophysiology of GvHD and identify novel targets for the manipulation of Tregs to optimize cellular immune intervention strategies. Keywords: cell type comparison Relative gene expressions were determined by normalized intensity values. GeneSpring analysis was performed using the Treg transcriptome data with following comparisons: no GvHD d90 versus no GvHD d150, no GvHD d90 versus acute GvHD, no GvHD d150 versus chronic GvHD, acute GvHD versus chronic GvHD, acute GvHD versus GvHD d90 and chronic GvHD versus GvHD d150 (Figure 2). Cut-off was a transcript fold change of 2 or -2 in at least one comparison. Student´s t-test was used to identify significant expression changes.
