P105 THE PROGRESSION OF INFLAMMATORY BOWEL DISEASE THROUGHOUT LATIN AMERICA: A SYSTEMATIC REVIEW
The incidence and prevalence of ulcerative colitis (UC) and Crohn’s disease (CD) is stabilizing in the Western world, but increasing in developing countries. However, epidemiological data on IBD is lacking from Latin American countries. The aim of th… Continue reading
03 TOWARDS DISEASE INTERCEPTION: CONTRIBUTION OF POLYGENIC RISK SCORES TOWARDS AGE-DEPENDENT RISK OF IBD IN A HIGH-RISK POPULATION
As the focus shifts to precision medicine, there is increasing prioritization of intervening before disease inception and early intervention as these will allow for disease prevention and/or prompt treatment with therapies with improved side-effect pro… Continue reading
P106 INFLAMMATORY BOWEL DISEASE CHARACTERIZATION OF SHARED AND UNIQUE ALTERATIONS IN IMMUNE CELLS, MOLECULAR PATHWAYS, AND TRANSCRIPTS
Inflammatory Bowel Disease (IBD), characterized by chronic inflammation of the intestine, is propelled by alterations in the immune profile and inflammatory mediators within affected tissue. However, as IBD pathobiology is heterogeneous in nature, a mo… Continue reading
P107 USING BIOINFORMATICS TO PRIORITIZE FOR BIOCHEMICAL AND BIOPHYSICAL ANALYSIS SNPS AND PROTEINS ASSOCIATED WITH INFLAMMATORY BOWEL DISEASE
Inflammatory bowel diseases (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), comprise a group of immune disorders of the digestive tract with significant negative impacts on quality of life. The etiologies are not well understood, b… Continue reading
P108 LONGITUDINAL MQTL STUDY IN BLOOD FROM PEDIATRIC CROHN’S DISEASE PATIENTS
Crohn’s disease (CD) is a relapsing-remitting inflammatory disorder with flares of inflammation. We have recently shown that CD associated DNA methylation signatures in blood are a transient consequence of inflammation. Here, we investigated how gene… Continue reading
30 ELEVATION OF PLASMA ONCOSTATIN M IS ASSOCIATED WITH PRIMARY BIOCHEMICAL NONRESPONSE AND SECONDARY CLINICAL NONRESPONSE TO INFLIXIMAB IN PEDIATRIC CROHN’S DISEASE PATIENTS
Oncostatin M (OSM) and OSM receptor (OSMR) were found to be highly expressed in inflamed intestinal tissue in patients with Crohn’s disease (CD) and ulcerative colitis (UC).1 West et al. also found elevations of mucosal OSM was strongly associated w… Continue reading
P109 DISTINCT MECHANISMS OF INTEGRIN ACTIVATION IN REGULATORY T CELLS MODULATE INFLAMMATORY BOWEL DISEASE AND AUTOIMMUNITY
The recruitment of lymphocytes from the circulation to the gut mucosa plays a critical role in inflammatory bowel disease (IBD); in particular, most classes of T cells promote disease; however regulatory T cells (Treg) suppress immune responses and res… Continue reading
P110 GUT MICROBIOTA CHANGES DIRECLTY INDUCED BY IL-1α NEUTRALIZATION LEAD TO REDUCTION OF ILEITIS AND DSS-INDUCED COLITIS IN SAMP1/YITFC MICE
We have previously shown that neutralization of IL-1α with a specific murine monoclonal antibody (FLO1) in 25-wk old SAMP1/YitFc (SAMP) mice with established CD-like ileitis, ameliorates ileitis severity. These results were associated with gut microbi… Continue reading
P111 TGFβ SIGNALING SUPPRESSES COLON EPITHELIAL INFLAMMATORY RESPONSES
It is well-established that microbiota and immune cells signal to colon epithelial cells to increase production of chemokines and pro-inflammatory cytokines that can accelerate inflammation, but we have found that TGFβ/SMAD4 signaling in colon epithel… Continue reading
P113 COMPARATIVE TRANSCRIPTOMIC ANALYSIS OF IBD MOUSE MODELS AND PATIENT COHORTS FOR INTERSPECIES TRANSLATION
The complex inflammatory bowel diseases, Crohn’s Disease (CD) and Ulcerative Colitis (UC), are driven by a myriad of immune, microbial, and environmental factors that manifest in tissue inflammation and lesions. Though several mouse models exist for … Continue reading
