Project description:Background: Hepatitis E Virus (HEV) is a new causative agent of chronic hepatitis in solid organ transplant recipients in Europe. Factors associated with the occurrence and persistence of chronic HEV infection remain largely unknown but chronic evolution seems to be the consequence of hostM-bM-^@M-^Ys immunological factors rather than of viral factors. Method: In a prospective case-control study, we have determined in whole blood of chronically HEV-infected kidney-transplant recipients the host response using microarray technology. Results: Chronically HEV-infected kidney-transplant recipients exhibited a specific transcriptional program, in which interferon effectors were prominent. The intensity of expression of each signatureM-bM-^@M-^Ys gene was significantly lower in patients who were subsequently cleared of HEV than in patients who were not. Furthermore, in patients who were cleared of HEV, a higher expression of these genes was associated with a longer delay until HEV clearance. Conclusions: The specific transcriptional program determined in chronically HEV-infected kidney-transplant recipients suggests an activation of type I interferon response. Intensity of interferon-stimulated genes expression could be useful to forecast the outcome of infection. High expression of interferon-stimulated genes could signify a dysregulation in the interferon response that might favour the persistence of the HEV infection.

Project description:This is an RNA-seq study of human lung transplant recipients. Bronchoalveolar lavage cells were collected on the first day after lung transplant. We performed bulk RNA-sequencing on 19 lung transplant recipients with severe primary graft dysfunction (PGD) and 19 lung transplant recipients without primary graft dysfunction. As this data is human identifiable, raw data are not included in this record.

Project description:Post-transplant lymphoproliferative disorders (PTLD) are a major complication of solid organ transplantation and represent a cause of severe morbidity and mortality among transplanted patients. Apart from EBV infection, knowledge of the pathogenesis of monoclonal PTLD is limited. Powerful analysis techniques, such as whole genomic DNA profiling (arrayCGH), can improve our understanding of PTLD pathogenesis. Toward this aim, we obtained the whole genome profiling using the Affymetrix GeneChip Human Mapping 10k 2.0 from 20 cases of PTLD and we compared them with those assessed in 25 cases of DLBCL from immunocompetent patients, as a control group. Recurrent lesions were detected among all the samples. Chromosome 18q, 7q, 3q and 12 were the most common gains in DLBCL of immunocompetent hosts. Chromosomes 5p and 11p were commonly gained in PTLD-DLBCL. The latter had frequent losses of 6q, 17p, 1p, and 9p. Chromosome 12p was the most frequent target of deletions among PTLD-DLBCL. The LOH pattern was characterized by involvement of chromosomes 13q and 17p in DLBCL and 10, 1q, 9p and 11q among PTLD-DLBCL. Interestingly, LOH did not always match the DNA loss. In particular, chromosome 10 seemes to be targeted by uniparental disomy in PTLD. Small deletions and gains, involving both known (BCL2 and PAX5) and unknown genes (ZDHHC14), have been identified. Our data suggest that PTLD share, at a lower frequency, common genetic aberrations with DLBCL from immunocompetent patients. The demonstration of 9p13 amplification indicates the importance of PAX5 in PTLD. The combination of DNA copy number and LOH assessment lead to the hypothesis that uniparental disomy may be a potential mechanism in B-cell lymphomagenesis. Twenty specimens of monoclonal B-cell PTLD, collected from 20 solid organ transplant recipients. Keywords: Genomic DNA on Affymetrix 10K SNP array
