Project description:The aim of this study is to investigate the molecular mechanisms of IL23-IL17 immune axis in IBD, with particular attention to its role in maintaining mucosal barrier integrity under both physiological and pathological conditions
Project description:We generated genome-wide chromatin-state maps of immune cells purified from LPMC of IBD and non-IBD patients by using next generation sequencing.
Project description:We obtained transcriptome profiling (SAGE-seq) of immune cells purified from LPMC of IBD and non-IBD patients by using next generation sequencing.
Project description:Clinical remission is apparent when laboratory markers of inflammation are normal and clinical symptoms are absent. However, sub-clinical inflammation can still be present. A detailed analysis of the immune status during this inactive state of disease may provide a useful tool to subcategorize patients with subclinical immune activation We performed (un)supervised clustering analysis of IBD-associated genes and applied IngenuityM-BM-. pathway software to identify specific molecular profiles between patients. We analyzed RNA gene expression profiles of peripheral blood leucocytes (PBL) from pediatric IBD patients in clinical remission and age-matched controls.
Project description:Group 3 innate lymphoid cells (ILC3s) are abundant in the developing or healthy intestine to critically support tissue homeostasis in response to microbial cues and other environmental signals. However, during gastrointestinal disease including infections, colorectal cancer, or inflammatory bowel disease (IBD), intestinal ILC3 numbers are dramatically reduced and the remaining ILC3s become dysfunctional which fuels disease and barrier breakdown. To define the underlying transcriptomic changes, we employed RNA sequencing of ILC3s from IBD patients. This may help to gain a deeper understanding of the mechanisms driving these alterations and ultimately lead to novel preventive, diagnostic, or therapeutic opportunities in IBD.
Project description:The effects of stimulating intestinal epithelial cells with Th17 cytokines, IL17 and IL22, was investigated Experiment Overall Design: The human colonic epithelial cell line, T84 was grown to confluency in standard transwell plates and either mock treated, or treated with cytokines IL17 and IL22
Project description:q exactive hf, 28 min method, comparison between IBD patients and ctrl methanol extraction, human serum and feces methanol extraction
Project description:Mucosal-luminal interface (MLI) samples were collected from a cohort of children with new-onset IBD and microbial cells were harvested and processed for metaproteomic analysis. Deep metaproteomics data analysis was then performed for better understanding the MLI microbiota functions in the development of pediatric IBD.
