Expression of CCL20 and Its Corresponding Receptor CCR6 Is Enhanced in Active Inflammatory Bowel Disease, and TLR3 Mediates CCL20 Expression in Colonic Epithelial Cells
Skovdahl, Helene Kolstad; Granlund, Atle Van Beelen; Østvik, Ann Elisabet; Bakke, Ingunn; Bruland, Torunn; Torp, Sverre Helge; Damås, Jan Kristian; Sandvik, Arne Kristian (Journal article; Peer reviewed, 2015)Background: The chemokine CCL20 and its receptor CCR6 are putative drug targets in inflammatory bowel disease, and CCL20 is a novel IBD predilection gene. Previous findings on the CCL20 response in these diseases are ... -
Expression of Toll-like receptor-3 is enhanced in active inflammatory bowel disease and mediates the excessive release of lipocalin 2
Østvik, Ann Elisabet; Granlund, Atle Van Beelen; Torp, Sverre Helge; Flatberg, Arnar; Beisvag, Vidar; Waldum, Helge; Flo, Trude Helen; Espevik, Terje; Damås, Jan Kristian; Sandvik, Arne Kristian (Journal article; Peer reviewed, 2013)Anti-microbial peptides might influence the pathogenesis and course of inflammatory bowel disease (IBD). We sought to clarify the role of the anti-microbial glycoprotein lipocalin 2 (LCN2) in the colon by determining its ... -
Mucosal toll-like receptor 3-dependent synthesis of complement factor B and systemic complement activation in inflammatory bowel disease
Østvik, Ann Elisabet; Granlund, Atle Van Beelen; Gustafsson, Björn; Torp, Sverre Helge; Espevik, Terje; Mollnes, Tom Eirik; Damås, Jan Kristian; Sandvik, Arne Kristian (Journal article, 2014)Background: Recent studies link Toll-like receptor 3 (TLR3) to the pathogenesis of inflammatory bowel disease (IBD). Screening TLR3-agonist response in an intestinal epithelial cell line, we found complement factor B mRNA ... -
Relevance of TNBS-Colitis in Rats: A Methodological Study with Endoscopic, Historical and Transcripttomic Characterization and Correlation to IBD
Brenna, Øystein; Furnes, Marianne Waldum; Drozdov, Ignat; Granlund, Atle Van Beelen; Flatberg, Arnar; Sandvik, Arne Kristian; Zwiggelaar, Rosalie; Mårvik, Ronald; Nordrum, Ivar Skjåk; Kidd, Mark; Gustafsson, Björn (Journal article; Peer reviewed, 2013)Background: Rectal instillation of trinitrobenzene sulphonic acid (TNBS) in ethanol is an established model for inflammatory bowel disease (IBD). We aimed to 1) set up a TNBS-colitis protocol resulting in an endoscopic ... -
The guanylate cyclase-C signaling pathway is down-regulated in inflammatory bowel disease
Brenna, Øystein; Bruland, Torunn; Furnes, Marianne Waldum; Granlund, Atle Van Beelen; Drozdov, Ignat; Emgård, Johanna; Brønstad, Gunnar; Kidd, Mark; Sandvik, Arne Kristian; Gustafsson, Björn (Journal article; Peer reviewed, 2015)Objective. Activation of membrane receptor guanylate cyclase-C (GC-C) is implicated in gastrointestinal fluid and electrolyte balance, preservation of intestinal barrier integrity, anti-trophic effects and inhibition of ... -
Whole Genome Gene Expression Meta-Analysis of Inflammatory Bowel Disease Colon Mucosa Demonstrates Lack of Major Differences between Crohn's Disease and Ulcerative Colitis
Granlund, Atle Van Beelen; Flatberg, Arnar; Østvik, Ann Elisabet; Drozdov, Ignat; Gustafsson, Björn; Kidd, Mark; Beisvag, Vidar; Torp, Sverre Helge; Waldum, Helge; Martinsen, Tom Christian; Damås, Jan Kristian; Espevik, Terje; Sandvik, Arne Kristian (Journal article; Peer reviewed, 2013)Background: In inflammatory bowel disease (IBD), genetic susceptibility together with environmental factors disturbs gut homeostasis producing chronic inflammation. The two main IBD subtypes are Ulcerative colitis (UC) ...
