Transcriptome of RCD-2 biopsies

ABSTRACT: About 5% of celiac disease (CeD) patients do not respond to a gluten-free diet and progress to refractory celiac disease (RCD), a severe progression that is characterized by infiltration of intraepithelial T-lymphocytes (IELs). RCD type II (RCDII) patients show clonal expansions of IELs that result in a poor prognosis and a high mortality rate through development of aggressive enteropathy-associated T-cell lymphoma.
RCDII has a poor prognosis (5-year survival rate <50%) also because of the development of enteropathy-associated T-cell lymphoma. Diagnosis of RCDII is complex and involves a combination of several techniques such as multiplex PCR analysis to determine the clonality of T-cell receptor gene rearrangements and immunohistochemistry or flow-cytometry to define the cell surface markers of IELs. Therefore studying the genetics and genomics of RCD2 susceptibility may provide novel insights into mechanistic basis for RCD2 development. The aim of this experiment was to profile the global gene expression changes in order to understand the dysregulated pathways in RCD2 biopsies and to uncover downstream pathways affected by RCD2 genetic susceptibility loci.
All patients were diagnosed with RCD2 and gut biopsies were collected from these patients to perform microarray based gene expression analysis. RNA from eleven RCD2 biopsy samples were analyzed using Illumina Human Ref8 v1 array.

Gene expression profiling of Type II Enteropathy-associated T-cell lymphoma

Project description:Type II Enteropathy-associated T-cell lymphoma (Type II EATL) is an aggressive intestinal T-cell lymphoma with poor prognosis and has not been molecularly profiled. Through targeted amplicon sequencing, we identified a large portion of Type II EATL samples that harbor mutations in the STAT5B, JAK3 and GNAI2 genes. Here we performed gene expression profiling on four Type II EATL samples in order to better characterize this disease. As Type II EATL is suggested to arise from CD8+ IELs, we integrated our data with publicly available profile of CD8Î±Î± and CD8Î±Î² T-cells from healthy donors (GSE33374). Gene expression profiling independently demonstrated strong enrichment of several aspects of GPCR and JAK-STAT signaling pathways. Moreover, an significant association was identified with genes containing STAT5B binding sites in their promoters. Microarray gene expression profiling was performed on 4 Type II Enteropathy-associated T-cell lymphoma and a combination of unsupervised and supervised clustering was performed to determine any differentially activated pathways between samples with tumor and healthy human CD161++CD8aa and CD161++CD8ab T cells (found under accession number GSE33374)

INTERLEUKIN 15-DEPENDENT T CELL-LIKE INNATE INTRAEPITHELIAL LYMPHOCYTES DEVELOP IN THE INTESTINE AND TRANSFORM INTO LYMPHOMAS IN CELIAC DISEASE

Project description:The nature of gut intraepithelial lymphocytes lacking antigen receptors remains controversial. Herein we showed that, in humans and in mice, innate intestinal intraepithelial lymphocytes expressing intracellular CD3 (iCD3+ innate IELs) differentiate along an Id2 transcription factor (TF)-independent pathway in response to TF NOTCH1, interleukin 15 (IL-15) and Granzyme B signals. In NOTCH1-activated human hematopoietic precursors, IL-15 induced Granzyme B, which cleaved NOTCH1 into a peptide lacking transcriptional activity. As a result, NOTCH1 target genes indispensable for T cell differentiation were silenced and precursors were reprogrammed into innate cells with T cell marks including intracellular CD3 and T cell rearrangements. This pathway was operational in vivo in the mouse gut and led to the local differentiation of iCD3+ innate IELs from a bone marrow-derived precursor. In a subset of celiac patients, iCD3+ innate IELs with gain-of-function mutations in Janus kinase 1 or Signal transducer and activator of transcription 3 displayed enhanced response to IL-15 and acquired a selective advantage that favored clonal expansion and transformation into lymphoma. Overall we characterized gut T cell-like innate IELs, deciphered their pathway of differentiation, and showed their malignant transformation in celiac disease.

Novel type of EATL evolving from mucosal M-NM-3M-NM-4-T-cells in a RCD type I patient

Project description:Enteropathy associated T-cell lymphoma (EATL) is a rare non-Hodgkin lymphoma that may complicate celiac disease and typically occurs in patients with refractoriness to the gluten- free diet. The majority of these patients harbor intra-epithelial lymphocytes (IEL) with an aberrant phenotype in the small intestine which are thus considered as the M-bM-^@M-^XprecursorM-bM-^@M-^Y lymphoma cells. We here report on a case of extra-intestinal EATL that originated from a clonal M-NM-3M-NM-4-IEL population rather than from aberrant IEL. This EATL displayed a distinctive pattern of immunophenotypical, T-cell receptor immunogenetic, and chromosomal aberrancies defining this lymphoma as a novel variant of EATL. sample vs reference

Novel type of EATL evolving from mucosal γδ-T-cells in a RCD type I patient

Project description:Enteropathy associated T-cell lymphoma (EATL) is a rare non-Hodgkin lymphoma that may complicate celiac disease and typically occurs in patients with refractoriness to the gluten- free diet. The majority of these patients harbor intra-epithelial lymphocytes (IEL) with an aberrant phenotype in the small intestine which are thus considered as the ‘precursor’ lymphoma cells. We here report on a case of extra-intestinal EATL that originated from a clonal γδ-IEL population rather than from aberrant IEL. This EATL displayed a distinctive pattern of immunophenotypical, T-cell receptor immunogenetic, and chromosomal aberrancies defining this lymphoma as a novel variant of EATL.

Gene expression in duodenal biopsy samples from CVID enteropathy patients and healthy controls

Project description:A subgroup of CVID patients presents with gastrointestinal complications (enteropathy), which manifests in the duodenum as celiac like-diese ase. CVID enteropathy patients can present with severe histopathology in form of villous atrophy (CVID VA) or without VA (CVID noVA). RNAseq data from CVID VA and CVID noVA derived duodenal tissues were compared to each other and to healthy controls.
