About this Research Topic
The gastrointestinal tract is the largest surface in mammals' body, and is in unceasing contact with a huge load of microorganisms, constituting the intestinal microbiota, and different antigens and xenobiotic coming from the diet. As such, intestinal innate and adaptive immune systems are finely regulated in order to tolerate commensal microorganisms and food-derived molecules, while maintaining the ability to mount a vigorous immune response against pathogens, followed by a prompt restoration of mucosal homeostasis.
Indeed, perturbations in these precise regulatory mechanisms may lead to the occurrence of inappropriate immune activity and/or the persistence of an inflammatory response and, thus, to the onset of intestinal diseases; in fact, several gut disorders arise from uncontrolled, chronic inflammation, as is the case for Inflammatory Bowel Diseases, Microscopic Colitides, Coeliac Disease and Diverticular Disease.
Several factors contribute to the development of the aforementioned clinical entities, including the composition of host microbiota, host immune system features and potential environmental stimuli, although, many pathogenetic mechanisms have yet to be completely elucidated. Undeniably, inflammatory conditions of the gut represent a significant burden for the Health Systems of Westernized countries, as treatment options are not curative and those disorders usually relapse.
Therefore, the aim of the present Research Topic is to further elucidate mechanisms leading to the onset and/or worsening of intestinal inflammation and recapitulate recent advances in the knowledge of the pathogenesis and clinical management of gut inflammatory conditions.
Potential topics include, but are not limited to:
• Pathogenesis and clinical aspects of Inflammatory Bowel Diseases
• Pathogenesis and clinical aspects of Coeliac Disease
• Pathogenesis and clinical aspects of Microscopic Colitides
• Pathogenesis and clinical aspects of Diverticular Disease
• Microbiota characterization and interactions with mucosal immune system
• Biomarkers of intestinal inflammation
