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:We have employed miRNA microarray expression profiling to identify miRNA differentially expressed in neonatal bowel tissues with different gastrointestinal conditions. Bowel tissues were collected from infants who underwent surgery treatment for necrotizing enterocolitis (NEC), spontaneous intestinal perforation (SIP). Infants with other non-inflammatory, congenital intestinal conditions were employed as the Surgical-Control. Differential miRNA microarray analysis was performed.
Project description:We have employed whole genome microarray expression profiling to identify genes differentially expressed in neonatal bowel tissues of different gastrointestinal conditions. Bowel tissues were collected from infants who underwent surgery treatment for necrotising enterocolitis (NEC) and spontaneous intestinal perforation (SIP). Infants with other non-inflammatory, congenital intestinal conditions were employed as the Surgical-Control. Differential whole genome microarray analysis was performed.
Project description:In this study we wanted to identify baseline predictors of successful vedolizumab therapy in patients with inflammatory bowel disease.
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 spatial transcriptomics at single-cell resolution (CosMx Spatial Molecular Imaging) to human inflamed and uninflamed intestine.
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.
