Role of beta3-adrenergic receptors in intestinal diseases

2022

The Inflammatory Bowel Diseases (IBD), characterized by a gastro-intestinal tract inflammation, are a global health-care problem due to their morbidity, mortality and the constant increase in their worldwide incidence. The available therapies are still not curative only providing temporary symptomatic relief and reduction in complications.Although etiology is still unclear, IBD results in an interplay of various factors among which impaired and/or inappropriate immune response toward intestinal bacteria. Increasing disease incidence link environmental triggers occurring during socioeconomic development to IBD, especially stress. In this work, we aimed to investigated the role of adrenergic …

Hypoxia Positively Regulates the Expression of pH-Sensing G-Protein–Coupled Receptor OGR1 (GPR68)

2016

Background & Aims: A novel family of proton-sensing G-proteinâcoupled receptors, including ovarian cancer G-proteinâcoupled receptor 1 (OGR1) (GPR68) has been identified to play a role in pH homeostasis. Hypoxia is known to change tissue pH as a result of anaerobic glucose metabolism through the stabilization of hypoxia-inducible factor-1α. We investigated how hypoxia regulates the expression of OGR1 in the intestinal mucosa and associated cells. Methods: OGR1 expression in murine tumors, human colonic tissue, and myeloid cells was determined by quantitative reverse-transcription polymerase chain reaction. The influence of hypoxia on OGR1 expression was studied in monocytes/macrophages and…

Anti-inflammatory Function of High-Density Lipoproteins via Autophagy of IκB Kinase

2015

Background & Aims: Plasma levels of high-density lipoprotein (HDL) cholesterol are frequently found decreased in patients with inflammatory bowel disease (IBD). Therefore, and because HDL exerts anti-inflammatory activities, we investigated whether HDL and its major protein component apolipoprotein A-I (apoA-I) modulate mucosal inflammatory responses in vitro and in vivo. Methods: The human intestinal epithelial cell line T84 was used as the in vitro model for measuring the effects of HDL on the expression and secretion of tumor necrosis factor (TNF), interleukin-8 (IL-8), and intracellular adhesion molecule (ICAM). Nuclear factor-κB (NF-κB)-responsive promoter activity was studied by …

A real life comparison of the efficacy of adalimumab versus golimumab in moderate-to-severe ulcerative colitis. A multicenter experience from the sic…

2017

Introduction: Adalimumab (ADA) and golimumab (GOL) are effective in the induction and maintenance treatment of moderate-to-severe ulcerative colitis (UC). No comparable data between the 2 drugs are available up to now. Aims & Methods: We reported the Sicilian Network experience on the comparative efficacy of ADA and GOL in patients (pts) with moderate-to-severe UC. From June 2015 until April 2017, 197 consecutive pts with moderate to severe UC were treated with ADA or GOL. The efficacy was evaluated at 8 week and at the end of the follow up considering ‘‘clinical response’’ (reduction of at least 2 points of Partial Mayo Score with concomitant steroid reduction or discontinuation) and “…

Third year IB high school students' perceptions on the international baccalaureate diploma programme: internationalisation, English medium instructio…

2014

Tämän kvalitatiivisen tutkielman tavoitteena oli selvittää viimeisen vuosikurssin käyneiden IB-lukiolaisten käsityksiä opiskelusta suomalaisessa IB-lukiossa. Aineiston keruussa käytettiin puolistrukturoituja teemahaastatteluja, ja tutkimusta varten haastateltiin seitsemää suomalaisen IB-lukion oppilasta. Tutkimuskysymykset koostuivat seuraavista aihealueista: IB-lukioon hakeminen ja koulutuksen rakenne, IB-opiskelijaprofiili, englannin kielen rooli koulutuksessa, jatkokoulutus- ja uraodotukset sekä kansainvälisyys. Tutkimustulokset osoittavat, että suomalaiset IB-lukiolaiset kokevat jo kouluaikana olevansa hyvin kansainvälisesti suuntautuneita. He pitävät opiskelua englannin kielellä tärkeä…

ROLE OF CHAPERONES IN HEALTHY BOWEL AND IBD.

2015

The chaperoning system is the wole complement of chaperones, co-chaperones and chaperone cofactors of the body that preserves cell and tissue homeostasis. Its structural and/or functional defects can cause pathologic conditions, nemed chaperonopathies. Large bowel homeostasis includes a healthy status of the mucosal tissues and the microbiota. An alteration of one of them may determine, in turn, modifications of the other. Molecular chaperones of bacteria and human origin have been implicated in inflammatory bowel disease (IBD). In IBD chaperone levels usually increase and their cellular and subcellular loclization change. This is considered a physiological stress-response of mucosal cells …

IBD, malignancy and oral microbiota: Analysis of the literature

2016

The human microbiota, in adults, varies in number and species based on the location in the gastrointestinal tract. The highest concentration is at the intestinal level, where mainly Bacteroidetes, Actinobacteria, Firmicutes and proteobacteria are found. Instead, in the oral cavity, five major phyla exists. Firmicutes, Actinobacteria, Proteobacteria, Bacteroidetes and Fusobacteria. Variations in the microbiota cause bysbiosis, which is responsible to a great extent for the onset of many diseases including inflammatory bowel disease (IBD) and colorectal cancer (CRC). In some cases (8-10%) IBD has shown oral manifestations that may reflect a change in the composition of the oral microbiota. Th…
