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

ABSTRACT: 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.

Phenotypic and genomic analysis of an exceptional case of enteropathy associated T cell lymphoma

Project description:Approximately 2–5% of adult-onset coeliac disease (CD) patients develops refractory coeliac disease (RCD). In contrast to RCD type I, RCD type II is characterised by the presence of aberrant small intestinal intraepithelial T-lymphocytes (IEL) expressing cytoplasmic CD3 but lacking surface expression of CD3, CD4 and CD8. Development of Enteropathy Associated T-cell Lymphoma (EATL) is directly associated with the presence of >20% aberrant IEL in RCD II patients and has a very poor prognosis. We report on an exceptional case of EATL presenting as leukemic ascites and on the unique opportunity to perform extensive phenotypic and genomic analysis of this malignancy. Flow cytometric immunophenotyping of the ascitic EATL presentation showed CD30 expression typical for EATL and loss of the above mentioned surface markers similar to the aberrant IEL it originated from, as indicated by an identical monoclonal TCR-gamma rearrangement. In addition, expression of a substantial number of markers, including CD2, CD7, CD11a/CD18, CD52, CD103 and granzyme B was lost, which has not been reported sofar. Expression of proliferation markers Ki-67 en PCNA was clearly detected in the majority of EATL cells. Karyotype and comparative genomic hybridisation (CGH) analyses showed many genomic alterations, including chromosomal gains and losses up to 47Mb not previously reported for EATL. In conclusion, the current exceptional EATL presentation displays both immunophenotypic and genomic alterations not described previously and not included in the current WHO classifications of lymphoid malignancies.

Comprehensive proteomics analyses of IL-15 driven activation of intestinal intraepithelial lymphocytes

Project description:Intestinal intraepithelial lymphocytes (IEL) are an abundant population of tissue-resident T cells that protect the gut from pathogens and maintain intestinal homeostasis. The cytokine IL-15 is trans-presented by epithelial cells to IEL in complex with the IL-15 receptor α chain (IL-15Rα) and plays essential roles both in maintaining IEL homeostasis, and in inducing IEL activation in response to epithelial stress. When overproduced, IL-15 is a key driver of the gluten-induced enteropathy Coeliac disease, through cytotoxic activation of IEL. To better understand how IL-15 directly regulates both homeostatic and inflammatory functions of IEL, we performed quantitative proteomics of IL-15/Rα-stimulated murine IEL, sorted into their 3 main subpopulations, TCRγδ CD8αα, TCRαβ CD8αβ and TCRαβ CD8αα expressing IEL. The data reveal that high IL-15/Rα stimulation licenses cell cycle activation, upregulates the biosynthetic machinery in IEL, increases mitochondrial respiratory capacity and induces expression of cell surface immune receptors and adhesion proteins that potentially drive IEL activation.

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)

NPMâ??ALK permits the survival of thymic T cells with aberrant T cell receptor rearrangements enabling thymic escape and tumor development

Project description:We present evidence to support a new model of Anaplastic Large Cell Lymphoma (ALCL) pathogenesis in which the malignancy is initiated in early thymocytes, prior to TCR rearrangement which is bypassed in NPMâ??ALK transgenic mice following Notch1 expression. In support, we show that T cell receptor (TCR) rearrangements are aberrant in some human ALCL, yielding events that would not normally be permissive for survival during T cell development. However, a TCR is required for thymic egress and subsequent development of peripheral tumors in mice yet this TCR must be downâ??regulated for Tâ??cell lymphomagenesis. Children affected by ALCL may thus harbor lymphoma-initiating cells in the thymocyte population that seeds relapse after chemotherapy. comparative genomic hybridization data from 43 human Anaplastic Large Cell Lymphoma (ALCL) samples and control samples
