Assessing Cellular and Transcriptional diversity of IIeal Mucosa amongst Treatment Naïve and Treated Crohn’s disease

ABSTRACT: Crohn’s disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. We used single cell RNA sequencing (scRNAseq) to define the cellular and transcriptional activity of the mucosa at different stages of disease progression in CD.

Multi-Omics Characterization of Colon Mucosa and Submucosa/Wall from Crohn’s Disease Patients

Project description:Crohn’s disease (CD) is a subtype of inflammatory bowel disease (IBD) characterized by transmural disease. The concept of transmural healing (TH) has been proposed as an indicator of deep clinical remission of CD and as a predictor of favorable treatment endpoints. Understanding the pathophysiology involved in transmural disease is critical to achieving these endpoints. How-ever, most studies have focused on the colon intestinal mucosa, overlooking the contribution of the colon intestinal wall in Crohn’s disease. Multi-omics approaches have provided new avenues for exploring the pathogenesis of Crohn’s disease and identifying potential biomarkers. Therefore, we analyzed and compared the gene and protein expression and dysregulated biological functions in the distinct tissue compartments of mucosa and submucosa/wall of colon resections from CD patients. We aimed to use transcriptomic and proteomic technologies to compare immune and mesenchymal cell profiles and pathways in the mucosal and submucosa/wall compartments to better understand refractory disease elements to achieve transmural healing. We employed a comprehensive multi-omics approach to investi-gate the molecular profiles of the colon mucosa and submucosa/wall compartments in patients with chronic Crohn’s disease. The results revealed similarities and differences in gene and protein ex-pression profiles, metabolic mechanisms, and immune and non-immune pathways between these two compartments. Additionally, the identification of protein isoforms highlights the complex molecular mechanisms underlying this disease. These findings have the potential to inform the development of novel therapeutic strategies to achieve TH.

IBD single cell data from colonic mucosa

Project description:Inflammatory bowel diseases (IBDs) including ulcerative colitis (UC) and Crohn’s disease (CD) are chronic inflammatory diseases with increasing worldwide prevalence that show a perplexing heterogeneity in manifestations and response to treatment. We applied single cell RNA sequencing (scRNAseq) a to colonic tissue from a combined healthy, UC and CD cohort.

RNA-seq of nonstenotic and stenotic areas of patients with Crohn’s disease

Project description:Fibrostenotic disease is a common complication in Crohn’s disease (CD). We performed bulk RNA sequencing (n=16) of paired intestinal biopsies taken from nonstenotic and stenotic areas of patients with CD (n=8).

Single-cell sequencing of developing human gut reveals transcriptional links to childhood Crohn’s disease

Project description:In this study, we performed single-cell transcriptional profiling of human embryonic and fetal gut samples obtained from 9 human embryos spanning ages 6-10 PCW and three regions (duo-jejunum, ileum and colon). Additionally, we profile mucosal biopsies from the terminal ileum of healthy children aged 4-12 years (n = 8) as well as a group of children newly diagnosed with Crohn’s disease (CD) (n = 7), a common form of IBD. Tissue samples were treated using an enzymatic dissociation protocol and single cell suspensions were then processed using the 3’v2 10x Genomics Chromium workflow. In a subset of samples, the intestinal epithelial cell fraction was enriched by performing magnetic bead sorting for EPCAM. In total, we generate single cell transcriptomes of ~90,000 primary human intestinal cells providing a rich resource and detailed roadmap. Using this data as well as scRNAseq profiles of human fetal gut derived organoids we describe embryonic and fetal epithelium composition, trace their differentiation dynamics and signaling partners, and provide links to regenerating Crohn’s disease epithelium.

16S V3-V4 -based microbial profiling of matched healthy and inflamed ileal mucosa from patients affected by Crohn’s disease

Project description:Crohn’s Disease (CD) pathogenesis is still unclear. Disorders in the mucosal immunoregulation and its crosstalk with the microbiota may represent an important component in tissue injury. We aimed to characterize the molecular immune response distribution within the ileal layers ( mucosa, submucosa and serosa) and to evaluate the correlated microbiota in pathological/healthy settings comparing first surgery/relapse clinical conditions.

The Gut Microbiota Metabolite Succinate promotes Adipose Tissue Browning in Crohn’s Disease

Project description:In Crohn’s disease (CD), microbe-host interactions are altered, with changes in microbial’s communities and barrier defects leading to translocation of microbes to surrounding adipose tissue (AT). We evaluated the presence of beige AT depots in CD and questioned whether succinate and/or bacterial translocation promotes white-to-beige transition in adipocytes.

Expression Profiles of Circular RNAs in colon biopsies from Crohn’s Disease Patients by Microarray Analysis

Project description:To investigate the expression profiles of circRNAs in colon tissues of the patients with Crohn’s Disease(CD) , ulcerative colitis (UC) and healthy controls (HC), we used circRNA microArray analysis form Arraystar to examine the expression of circRNAs in colon tissues of CD,UC and HC.
