An Investigation Into the Role of Optineurin in Macrophage-Mediated Acute Antibacterial Response in Inflammatory Bowel Disease
An investigation into the role of optineurin in macrophage-mediated acute antibacterial response in inflammatory bowel disease By Thean Soon Chew A thesis submitted to UCL for the degree of Doctor of Philosophy Division of Medicine 2015 1 I, Thean Soon Chew confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 ex nihilo nihil fit 3 Abstract Crohn’s disease (CD) is now recognised to be due to defective host responses to bacteria in genetically susceptible individuals. Others in our research group previously found defective neutrophil recruitment, bacterial clearance and monocyte-derived macrophage (MDM) proinflammatory cytokine secretion in CD. To investigate the defective cytokine secretion, we performed transcriptomic analysis and identified reduced MDM optineurin (OPTN) expression in 10% CD patients. Here, I show that macrophages stimulated with E. coli, bacterial Toll-like and NOD-like receptor ligands upregulate OPTN, a Golgi complex protein that regulates vesicle transport. In vitro, Optn-/- bone marrow-derived macrophages (BMDM) stimulated with E. coli secrete significantly lower levels of proinflammatory TNF and IL6 cytokines, which is normalised to wildtype levels on addition of lysosomal function inhibitors. In vivo, Optn-/- mice develop a more severe Citrobacter colitis with greater mortality, an early defective neutrophil recruitment to the bowel and lower levels of serum proinflammatory cytokines. The Optn-/- mice also demonstrated a similar phenotype of defective neutrophil recruitment and lower serum proinflammatory cytokines in an E. coli-induced peritonitis. These results indicate that the low OPTN expression originally identified in CD macrophages has likely contributed to an attenuated antibacterial response, which potentially led to the development of bowel inflammation. -

While major advances since 2000 have provided strong mechanistic clues implicating a version 1 de-regulation in the normal interaction among host genetics, immunity, 24 Apr 2020 microbiome, and the environment, more recent progress has generated entirely new hypotheses and also further refined older disease concepts. In this review, we focus specifically on these novel developments in the pathogenesis of ulcerative colitis. F1000 Faculty Reviews are written by members of the prestigious F1000 Faculty.
