RNA sequencing derived from intestinal biopsies from healthy controls and celiac disease patients

ABSTRACT: Aim: To compare the overall transcriptional profile in healthy controls and celiac disease patients. This dataset, was used to evaluate if our in vitro model (intestinal intraepithelial lymphocytes, desccribed in doi:10.1016/j.jaut.2020.10242 ) is representative of the transcriptional profile in the intestine under healthy or inflammatory conditions. Samples: Upper colonoscopy biopsies from 5 control and 11 celiac disease patients were taken, total RNA was extracted and RNA-sequencing was performed (without replicates)

Reprogramming of CTLs into natural killer-like cells in celiac disease

Project description:Celiac disease is an intestinal inflammatory disorder induced by dietary gluten in genetically susceptible individuals. The mechanisms underlying the massive expansion of interferon g–producing intraepithelial cytotoxic T lymphocytes (CTLs) and the destruction of the epithelial cells lining the small intestine of celiac patients have remained elusive. We report massive oligoclonal expansions of intraepithelial CTLs that exhibit a profound genetic reprogramming of natural killer (NK) functions. These CTLs aberrantly expressed cytolytic NK lineage receptors, such as NKG2C, NKp44, and NKp46, which associate with adaptor molecules bearing immunoreceptor tyrosine-based activation motifs and induce ZAP-70 phosphorylation, cytokine secretion, and proliferation independently of T cell receptor signaling. This NK transformation of CTLs may underlie both the self-perpetuating, gluten-independent tissue damage and the uncontrolled CTL expansion leading to malignant lymphomas in severe forms of celiac disease. Because similar changes were detected in a subset of CTLs from cytomegalovirus-seropositive patients, we suggest that a stepwise transformation of CTLs into NK-like cells may underlie immunopathology in various chronic infectious and inflammatory diseases.

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.

Gastrointestinal symptoms and pathology in patients with Common variable immunodeficiency

Project description:Based on the findings of increased IEL in duodenal biopsies in CVID, an overlap with celiac disease has been suggested. In the present study, increased IEL, in particular in the pars descendens of the duodenum, was one of the most frequent histopathological finding. We therefore examined the gene expression profile in pars descendens of duodenum in CVID patients with increased IEL (n=13, IEL mean 34 [range 22-56] IEL/100 EC), CVID with normal levels of IEL (n=7), celiac disease (n=10, Marsh grade 3a or above) and healthy controls (n=17) by gene expression microarray GI histopathological findings in 53 CVID patients that underwent upper and lower endoscopic examination were addressed. For the microarray analysis 20 CVID (7 CVID_normal and 13 CVID with incresed IEL), 10 patients with celiac diseases and 17 healthy controls were included.

Comparison of intestinal surface CD3- refractory celiac disease type II (RCDII) cell lines with intestinal surface CD3+ cell lines of non-RCDII patients

Project description:Analysis of transcriptional differences between aberrant (surface CD3-) RCDII cell lines and regular (surface CD3+) intraepithelial cell lines in order to characterize aberrant RCDII cells. All cell lines were cultured from duodenal biopsies of RCDII or non-RCDII (either celiac or non-celiac) patients. We compared 3 RCDII cell lines from RCDII patients P1-P3 with the following control cell lines: CD3+CD4+ T cell line from P1 and P3, CD3+CD8+ T cell line from P3 and mixed CD4/CD8+ T cell lines from non-RCDII patients. All control cells matched the phenotype of mature T cells (CD3+CD4+ and/or CD3+CD8+). Samples were randomly distributed among two BeadChips and measured in duplicates.
