Differences in microbiome populations following hematopoietic stem cell transplantation in Crohn?s disease patients

ABSTRACT: Treatment of severely refractory Crohn’s disease (CD) patients remains a clinical challenge. Recent studies show the efficacy of autologous hematopoietic stem cell transplant (HSCT) in these severely compromised patients. HSCT is thought to eliminate auto-reactive cells; however, no specific studies of immune reconstitution in CD patients are available. We studied a group of CD patients (n=18) receiving autologous HSCT. We studied changes in the microbiome induced by HSCT and some non-CD samples.

Differences in tissue immune cell populations following hematopoietic stem cell transplantation in Crohn’s disease patients

Project description:Treatment of severely refractory Crohn’s disease (CD) patients remains a clinical challenge. Recent studies show the efficacy of autologous hematopoietic stem cell transplant (HSCT) in these severely compromised patients. HSCT is thought to eliminate auto-reactive cells; however, no specific studies of immune reconstitution in CD patients are available. We studied a group of CD patients receiving autologous HSCT, with 50% of them achieving endoscopic drug-free remission. To elucidate the mechanism driving efficacy, we studied changes in the immune cell composition in tissue induced by HSCT.

HSCT is thought to eliminate auto-reactive cells; however, no specific studies of immune reconstitution in CD patients are available. We studied a group of CD patients (n=18) receiving autologous HSCT and non-IBD patients (n=19) to elucidate the mechanism of interaction with the microorganisms.

Expression data from whole blood in CD patients undergoing HSCT.

Project description:Treatment of severely refractory Crohn’s disease (CD) patients remains a clinical challenge. Recent studies show efficacy of autologous hematopoietic stem cell transplant (HSCT) in these severely compromised patients. HSCT is thought to eliminate auto-reactive cells; however the mechanisms are incompletely understood. We followed a group of patients (n=18) receiving autologous HSCT, with 50% of them achieving endoscopic drug-free remission. To elucidate the mechanism driving efficacy we compared the immunological changes induced by HSCT in responders and non-responders.

Adipose derived stem cells (ASCs) methylation differences between Crohn Disease and No-Crohn individuals

Project description:Pathological expansion of adipose tissue (AT) is supported by adipocyte precursors, termed adipose-derived stem cells (ASCs). Elucidation of mechanisms underlying ASC function may lead to therapeutic interventions to use in cell therapy treatments on Crohn’s disease patients. Using epigenome-wide association studies, we explored the impact of Crohn’s disease on the methylation signature of human ASCs

Endoscopic Detection of Dysplasia in Crohn ‘s Disease Patient

Project description:Patients with Crohn’s disease (CD) have an increased risk of small bowel adenocarcinoma (SBA). Long duration of CD is the main risk factor. SB dysplasia has been associated with SBA in 20% of cases, always described in diseased sites. The progression to neoplasia and natural history remains unknown but progression of inflammation to dysplasia and then to adenocarcinoma is suspected. As for surveillance recommendations for colorectal carcinoma in long standing inflammatory colonic disease, endoscopic screening of SB could be proposed in CD patients with risk factors of SBA. No study can be found in literature. The investigators propose a multicenter exploratory open study on prospective cohort of CD patients with high risk of dysplasia or cancer. The goal is evaluate the rate of dysplasia and adenocarcinoma detected by enteroscopy with biopsies in a high risk CD population

Immune-restricted epigenetic reader SP140 maintains macrophage identity and activation states critical to intestinal homeostasis [RNA-seq]

Project description:Introduction: SP140 is a bromodomain/plant homeo domain (PHD)-containing reader with immune-restricted expression, and single nucleotide polymorphisms (SNPs) within SP140 associate with Crohn’s disease (CD). However, the function of SP140 and the consequences of disease-associated SP140 SNPs have remained unknown. Results: Individuals carrying CD-associated SNPs within SP140 had defective SP140 mRNA splicing, diminished SP140 protein, and severely suppressed innate immune signatures that stratified them from other CD patients. Conclusion: SP140 is a critical orchestrator of macrophage identity, and a loss of SP140 due to genetic variation contributes to a molecularly defined subset of CD characterized by suppressed innate immunity.

Core Ileal Transcriptome in Pediatric Crohn Disease

Project description:We report the global pattern of ileal gene expression in a cohort of 359 treatment-naïve pediatric Crohn Disease, Ulcerative Colitis patients and controls. We focus on genes with consistent altered expression in inflamed and unaffected ileum of CD [ileal-involved CD (iCD) and non-invloved ileal CD (cCD)], but not in the ileum of ulcerative colitis or control.
