P154 SINGLE-CELL ANALYSIS OF T CELL PATHOGENESIS IN PEDIATRIC CROHN’S DISEASE
Crohn’s disease (CD) is chronic complex autoimmune condition characterized by inflammation of the gastrointestinal tract. Pediatric CD diagnosed in patients younger than 20 years of age comprises 30% of all diagnosed CD. There is significant data to … Continue reading
17 PERIPARTUM ANTIBIOTIC EXPOSURE INDUCES PERSISTENT GUT DYSBIOSIS, IMPAIRS THE DEVELOPMENT OF IMMUNE TOLERANCE, AND INCREASES RISK FOR INFLAMMATORY BOWEL DISEASE IN GENETICALLY SUSCEPTIBLE OFFSPRING
The prevalence and incidence of inflammatory bowel diseases (IBD) has rapidly increased over the past century. Although the etiology of IBD remains unclear, changes in societal norms, environment, diet, and lifestyles are likely contributory factors th… Continue reading
22 CX3CR1+ MONONUCLEAR PHAGOCYTES CONTROL IMMUNITY TO INTESTINAL FUNGI
Background and Objectives: Recent evidence suggests that intestinal fungal communities possess Immunomodulatory properties and can influence the development of intestinal inflammation. Serum antibodies against the Saccharomyces cerevisiae mannan (AS… Continue reading
23 ESTABLISHING THE SPECIFIC CONTRIBUTION OF ADHERENT AND INVASIVE ESCHERICHIA COLI TO THE ONSET OF INFLAMMATORY BOWEL DISEASE
Adherent and invasive Escherichia coli (AIEC) appear to expand during inflammation and are observed in the ileal mucosa in subsets of Crohn’s patients. However, AIEC pathogenesis is poorly understood and cause-effect relationships between AIEC and IB… Continue reading
25 IDENTIFICATION OF PATHOGENIC BACTERIA IN SEVERE CROHN’S DISEASE
Despite great advancements in therapy, it remains unclear why inflammation in the digestive system of patients suffering Crohn’s Disease (CD) is progressive and leads to complications (e.g., enteric fistulas) that are only alleviated by surgical remo… Continue reading
26 THE INTESTINAL MICROBIOME IN INFLAMMATORY BOWEL DISEASE ACROSS THE PEDIATRIC AGE RANGE
The influence of genomics, immune response, and environment on inflammatory bowel disease (IBD) varies among patients. We aimed to characterize the differences and determine age and disease effects on the gut microbiome across the pediatric age range, … Continue reading
27 CANDIDA TROPICALIS INFECTION MODULATES THE GUT MICROBIOME IN DSS-INDUCED COLITIS IN C57BL/6 MICE
Infections (candidiasis) caused by Candida spp. including C. tropicalis, have dramatically increased worldwide, indicating that this organism is an emerging pathogenic yeast. Our recent studies indicate that C. tropicalis is significantly higher in C… Continue reading
P155 ELUCIDATING INTERACTIONS BETWEEN THE IMMUNE SYSTEM AND THE GUT MICROBIOTA IN A REDUCTIONIST MURINE MODEL OF INFLAMMATORY BOWEL DISEASE
Patients with inflammatory bowel disease (IBD) have altered intestinal microbial composition, but whether this altered microbiota is a cause or consequence of inflammation is unclear. The importance of the gut microbiota in IBD pathogenesis has been sh… Continue reading
P156 PSYCHOLOGICAL STRESS INDUCES ALTERATIONS IN BEHAVIOR AND THE MUCOSAL IMMUNE SYSTEM IN A SPONTANEOUS MOUSE MODEL OF ILEITIS
Patients with Crohn’s disease (CD) suffer from abnormally high rates of depression and anxiety. Depression among patients with CD are higher than other debilitating chronic medical conditions, such as cancer. Behavioral co-morbidities are associated … Continue reading
P157 THE ASSOCIATION STUDY BETWEEN HLA GENOTYPE AND MUCOSAL MICROBIAL COMPOSITION IN PATIENTS WITH INFLAMMATORY BOWEL DISEASES
Although inflammatory bowel diseases (IBD) is presumed to develop as the result of dysregulated immune response to the intestinal microbiota in genetically susceptible hosts, the association between microbiota and genotypes in IBD patients remains uncl… Continue reading
