Transcriptomic Landscape of Treatment - Naïve Erosive Esophagitis

Project description:Erosive Esophagitis (EE) is one of the common forms of gastroesophageal reflux disease (GERD). We performed transcriptomic analysis (RNA sequencing) of esophageal biopsies from patients with EE and healthy controls to increase understanding of complex cellular and molecular pathways in EE.

Conserved interferon signature between adult and pediatric eosinophilic esophagitis

Project description:Eosinophilic esophagitis (EoE) is an allergic inflammatory disease of the esophagus that occurs in both children and adults. Previous studies of affected tissue in pediatric cohorts have identified prominent signatures of eosinophilia and type 2 inflammation. However, the details of the immune response in adults with EoE are still being elucidated. To determine whether EoE in adults shares inflammatory profiles with those observed in children, we performed RNA-sequencing of paired esophageal biopsies and blood samples from adults with EoE or gastroesophageal reflux disease (GERD). Unbiased analysis of differentially expressed genes in tissue revealed a strong interferon signature that was significantly enriched in EoE patients as compared to patients with GERD. Both type I and type II interferon responsive genes were upregulated in adult biopsies, but not in blood. A similar increase in expression of interferon gene sets was observed in pediatric EoE biopsies as compared to non-EoE samples, and in public pediatric and adult RNA-sequencing data. Finally, we found that peripheral CD4+ T cells from children with EoE produce IFNG upon activation with EoE-causal allergens. Together, this work identifies a conserved interferon signature in pediatric and adult EoE, highlighting a role for non-type 2 inflammatory networks in the disease process.

Persistent epithelial barrier dysfunction and Periostin accumulation in histologic remission Eosinophilic Esophagitis

Project description:Patients with Eosinophilic esophagitis (EoE) require long-lasting resolution of inflammation to prevent fibrostenosis and dysphagia. However, the dissociation between symptoms and histologic improvement suggests persistent molecular drivers despite remission. We aimed to characterize persisting molecular alterations in pediatric patients with EoE using tissue proteomics. Esophageal tissue biopsies (n=151) and clinical data were collected prospectively from pediatric patients with EoE (N=34), gastroesophageal reflux disease (GERD; N=10; inflammatory controls) or functional disorders (FD; N=20; non-inflammatory controls). Biospies (n=131) acquired from the diagnostic endoscopy and up to 7 follow-ups were considered for proteome analysis in patients with EoE, while for GERD and FD only biopsies from initial diagnosis were included. Histologically active EoE (15 eosinophils per high power field (hpf)) was diagnosed in 79 biopsies and 52 samples derived from patients with EoE in remission (15 eosinophils per hpf). After microdissection of the epithelium proteins were extracted from the esophageal tissue followed by a liquid chromatography-tandem mass spectrometry. Proteomic analysis identified 3,704 different proteins in total across all samples.

Transcriptomic profiling of the acute mucosal response to local food injections in adults with eosinophilic esophagitis

Project description:Background: Exposure of the esophageal mucosa to food allergens can cause acute mucosal responses in patients with eosinophilic esophagitis (EoE), but the underlying local immune mechanisms driving these acute responses are not well understood. Objective: To gain insight into the early transcriptomic changes that occur during an acute mucosal response to food allergens in EoE. Methods: Bulk RNA-sequencing was performed on esophageal biopsies from adult EoE patients (n = 5) collected before and 20 minutes after intramucosal injection of various food extracts in the esophagus. Baseline biopsies from non-EoE controls (n = 5) were also included. Results: At baseline, the transcriptome of the EoE patients showed increased expression of genes related to an EoE signature. After local food injection, we identified 40 genes with a potential role in the early immune response to food allergens (most notably CEBPB, IL1B, TNFSF18, PHLDA2, and SLC15A3). These 40 genes were enriched in processes related to immune activation, such as the acute phase response, cellular responses to external stimuli, and cell population proliferation. TNFSF18 (also called GITRL), a member of the TNF superfamily that is best studied for its co-stimulatory effect on T cells, was the most dysregulated early EoE gene showing a 12-fold increase compared with baseline and an 18-fold increase compared with a negative visual response. Further experiments showed that the esophageal epithelium may be an important source of TNFSF18 in EoE, which was rapidly induced by stimulating differentiated esophageal epithelial cells with the key EoE cytokine interleukin-13. Conclusion: Our data provide unprecedented insight into the transcriptomic changes that mediate the acute mucosal immune response to food allergens in EoE, and suggests that TNFSF18 may be an important effector molecule in this response.
