The award of an N-ECCO Travel Grant, organised by ECCO, enabled me to spend time as an intern in the prestigious Inflammatory Bowel Diseases Centre at Humanitas Research Hospital, the largest IBD centre in Italy. The Centre provides the most innovative treatments and therapeutic strategies for IBD patients in accordance with current scientific evidence and offers a multidisciplinary approach to IBD with the help of industry experts and novel technologies. At the Humanitas outpatient clinic dedicated to IBD, patients are followed by IBD nurse Simona Radice. In addition to the provision of medical assistance to patients, the Centre is strongly engaged in research activities aimed at developing new treatments and diagnostic and/or therapeutic strategies. Participation in clinical trials is subject to a preliminary clinical evaluation during a specialist visit to the Centre.

The role of Nlrp9b in regulating intestinal inflammation

Aim of the research

Innate immune signalling pathways, including inflammasome-forming Noll-like receptors (NLR), are thought to mediate the risk of Inflammatory Bowel Disease (IBD) since this system acts as the first line of defence in the recognition of enteric pathogens. In our preliminary study, we identified a new NLR member, Nlrp9b, whose role in the pathogenesis of IBD remains to be clarified. The aim of our study is to investigate the role of Nlrp9b in regulating intestinal inflammation and the underlying mechanisms.

TSG-6, a potential new therapeutic target in fistulising Crohn’s Disease

Background

Fistulising Crohn’s Disease (CD) represents a demanding, complex, and as yet unresolved issue, characterised by lesions with active pus drainage through the external fistula openings. Despite advances in understanding of the pathophysiology, to date there are no specific and efficient therapies or molecular markers for its treatment or prevention. TNF-α stimulated gene/protein-6 (TSG-6), an anti-inflammatory protein produced in response to signals from injured tissue, has been shown to exert remarkable therapeutic effects on colitis and on wound healing in various disease models.

Monocyte-derived macrophages as crucial players in the resolution of inflammation and tissue repair in Inflammatory Bowel Disease

Background

Inflammatory Bowel Disease (IBD) is characterised by chronic inflammation of the gastrointestinal tract leading to debilitating symptoms. No curative therapies are currently available for IBD, with the consequence that the disease has a significant impact on the emotional, financial and social status of patients and their families. Although most studies conducted on IBD over the past few decades have investigated abnormal adaptive immunity, the focus has recently shifted towards alterations in innate immune response. Recent data suggest a causal link between defects in the resolution of inflammation associated with impaired bacterial clearance, excessive cytokine secretion and altered monocyte-macrophage (Mφ) transition in patients with IBD.

Deciphering the gut-specific B cell response in Inflammatory Bowel Disease (IBD)

Aim of the research

Given that there is a large complement of mucosal B cells that plays a pivotal role in the regulation of the microbiome and in mucosal homeostasis, it is likely that they play an important but yet understudied role in the pathogenesis of IBD. Therefore, we hypothesize that mucosal inflammation as seen in IBD will induce a B cell response with homeostatic and perhaps pathogenic properties.

Investigation of the role of Par4-associated cell polarity and associated barrier defects in Inflammatory Bowel Diseases

Aim of the research

In Inflammatory Bowel Diseases (IBD), epithelial barrier defects occur as a consequence of chronic inflammation. Recent research has suggested that cell polarity alterations may be upstream of barrier defects and additionally play a role in IBD-associated carcinogenesis (colitis-associated and small intestinal carcinoma). Par4 is a gene encoding a protein crucial in the development of cell polarity. LKB1, its human homologue, is mutated in Peutz-Jeghers syndrome (PJS), a genetic condition characterised by a higher risk of epithelial cancers. Considering the pivotal role of Par4/LKB1 in the development of epithelial cell polarity, this project aims to assess its involvement in IBD-associated barrier defects and carcinogenesis.

Most patients with chronic IBD are diagnosed at a young age. After baseline diagnosis many of these young patients have to undergo repeated imaging procedures during the variable clinical course of their disease. Ultrasound, CT and MRI are used to image transmural alterations and extra-intestinal manifestations of the disease and to monitor response to treatment.

One of the main goals of ECCO is to promote IBD-related basic and clinical research as well as to foster interaction and productive collaboration among European research groups working in the IBD field. To achieve this goal, ECCO continues to award Grants, Fellowships and Travel Awards.

For 2018 the number of awardees has increased to an amazing total of more than 30.

Fat in IBD – Much more than an innocent bystander 

Within the framework of the 6^th SciCom Workshop, the role of fat and lipids in IBD pathogenesis was highlighted. Six highly interesting talks shed light on the fact that fat is much more than an innocent bystander in IBD.
