| 1 | Intestinal inflammation and colorectal cancer:A doubleedged sword?显示文摘Chronic inflammation is thought to be the leading cause of many human cancers including colorectal cancer(CRC).Accordingly,epidemiologic and clinical studies indicate that patients affected by ulcerative colitis and Crohn's disease,the two major forms of inflammatory bowel disease,have an increased risk of developing CRC.In recent years,the role of immune cells and their products have been shown to be pivotal in initiation and progression of colitis-associated CRC.On the other hand,activation of the immune system has been shown to cause dysplastic cell elimination and cancer suppression in other settings.Clinical and experimental data herein reviewed,while confirming chronic inflammation as a risk factor for colon carcinogenesis,do not completely rule out the possibility that under certain conditions the chronic activation of the mucosal immune system might protect from colonic dysplasia. | Angelamaria Rizzo Francesco Pallone Giovanni Monteleone Massimo Claudio Fantini | 2011 | World Journal of Gastroenterology2011，17，26： | 25 |
| 2 | Emerging role of IL-23/IL-17 axis in H pylori-associated pathology显示文摘Colonization of stomach by H pylori is followed by a marked infiltration of the mucosa with polymorphonuclear leukocytes, macrophages, and lymphocytes that very often remains asymptomatic, but in some circumstances can lead to the development of gastroduodenal ulceration, gastric carcinoma, and mucosa-associated lymphoid tissue lymphoma. The molecular mechanisms by which H pylori triggers and maintains the local immune response are complex, but there is evidence that cytokines produced by both immune and non-immune cells contribute to amplify the ongoing inflammation. H pylori infection is associated with a marked mucosal induction of T helper (Th) type 1 and Th17-type cytokines that is governed by specific antigen-presenting cell-derived molecules, such as interleukin (IL)-12 and IL-23. In this paper, we will review the available data on the expression and role of IL-23 and IL-17 in H pylori- related gastritis. | Roberta Caruso Francesco Pallone Giovanni Monteleone | 2007 | World Journal of Gastroenterology2007，13，42： | 20 |
| 3 | Interleukin-12 and Th1 immune response in Crohn’s disease: Pathogenetic relevance and therapeutic inplication显示文摘Crohn’s disease (CD) and ulcerative colitis (UC) are chronic inflammatory disorders of the gastrointestinal tract that share clinical and pathological characteristics. The most accredited hypothesis is that both CD and UC result from a deregulated mucosal immune response to normal constituents of the gut microflora. Evidence, however, indicates that the main pathological processes in these two diseases are distinct. In CD, the tissue- damaging inflammatory reaction is driven by activated type 1 helper T-cell (Th1), whereas a humoral response predominates in UC. Consistently, a marked accumulation of macrophages making interleukin (IL)-12, the major Th1-inducing factor, is seen in CD but not in UC mucosa. Preliminary studies also indicate that administration of a monoclonal antibody blocking the IL-12/p40 subunit can be useful to induce and maintain clinical remission in CD patients. Notably, the recently described IL-23 shares the p40 subunit with IL-12, raising the possibility that the clinical benefit of the anti-IL-12/p40 antibody in CD may also be due to the neutralization of IL-23 activity. This review summarizes the current information on the expression and functional role of IL-12 and IL- 12-associated signaling pathways both in patients with CD and experimental models of colitis, thus emphasizing major differences between IL-12 and IL-23 activity on the development of intestinal inflammation. | Ilaria Peluso Francesco Pallone Giovanni Monteleone | 2006 | World Journal of Gastroenterology2006，12，35： | 16 |
| 4 | Post-endoscopic retrograde cholangio-pancreatography pancreatitis:Is time for a new preventive approach?显示文摘Acute pancreatitis is the most common serious complication of endoscopic retrograde cholangio-pancre-atography (ERCP) and its incidence may exceed 25% in some high-risk patient subsets. In some patients, pancreatitis may follow a severe course with pancreatic necrosis, multiorgan failure, permanent disability and even death. Hence, approaches which minimize both the incidence and severity of post-ERCP pancreatitis are worth pursuing. Pancreatic stents have been used with some success in the prevention of post-ERCP, while so far pharmacological trials have yielded disappointing results. A recent multicenter, randomized, placebo-controlled, double-blind trial has shown that rectally administered indomethacin is effective in reducing the incidence of post-ERCP pancreatitis, the occurrence of episodes of moderate-to-severe pancreatitis and the length of hospital stay in high-risk patients. These results together with the demonstration that rectal administration of indomethacin is not associated with en-hanced risk of bleeding strongly support the use of this drug in the prophylaxis of post-ERCP pancreatitis. | Stella Tammaro Roberta Caruso Francesco Pallone Giovanni Monteleone | 2012 | World Journal of Gastroenterology2012，18，34： | 13 |
| 5 | Impairment of ghrelin synthesis in Helicobacter pyloricolonized stomach:New clues for the pathogenesis of H.pylori-related gastric inflammation显示文摘Ghrelin,the ligand of growth hormone secretagogue receptor 1a,takes part in several functions of the digestive system,including regulation of appetite,energy homeostasis,gastric acid secretion and motility.Ghrelin has also immunoregulatory properties and is supposed to inhibit some inflammatory pathways that can mediate gastric damage.Interestingly,ghrelin synthesis is reduced in the gastric mucosa of patients with Helicobacter pylori(H.pylori)infection,a worldwide condition inducing a T helper(Th)1/Th17 cell responsedriven gastritis,which may evolve towards gastric atrophy and cancer.In this article,we review the available data on the expression of ghrelin in H.pylori infection and discuss how the defective ghrelin synthesis may contribute to sustain the ongoing inflammatory response in this disease. | Omero Alessandro Paoluzi Giovanna Del Vecchio Blanco Roberta Caruso Ivan Monteleone Giovanni Monteleone Francesco Pallone | 2014 | World Journal of Gastroenterology2014，20，3： | 8 |
| 6 | Interleukin-21 triggers effector cell responses in the gut显示文摘In the gut of patients with Crohn's disease and patients with ulcerative colitis,the major forms of inflammatory bowel diseases(IBD) in humans,the tissue-damaging immune response is mediated by an active cross-talk between immune and non-immune cells.Accumulating evidence indicates also that cytokines produced by these cells play a major role in initiating and shaping this pathologic process.One such cytokine seems to be interleukin(IL)-21,a member of the common γ-chainreceptor family.IL-21 is produced in excess in the in-flamed intestine of patients with IBD mostly by activated CD4+ T helper cells co-expressing interferon-γ and follicular T helper cells.Moreover,both in vitro and in vivo studies indicate that excessive IL-21 production leads to the activation of multiple signaling pathways that expand and sustain the ongoing mucosal inflammation.In this article,we review the available data supporting the pathogenic role of IL-21 in IBD. | Daniela De Nitto Massimiliano Sarra Francesco Pallone Giovanni Monteleone | 2010 | World Journal of Gastroenterology2010，16，29： | 8 |
| 7 | Malignant gastric outlet obstruction:Which is the best therapeutic option?显示文摘Malignant gastric outlet obstruction(MGOO)is a clinical condition characterized by the mechanical obstruction of the pylorus or the duodenum due to tumor compression/infiltration,with consequent reduction or impossibility of an adequate oral intake.MGOO is mainly secondary to advanced pancreatic or gastric cancers,and significantly impacts on patients’survival and quality of life.Patients suffering from this condition often present with intractable vomiting and severe malnutrition,which further compromise therapeutic chances.Currently,palliative strategies are based primarily on surgical gastrojejunostomy and endoscopic enteral stenting with self-expanding metal stents.Several studies have shown that surgical approach has the advantage of a more durable relief of symptoms and the need of fewer re-interventions,at the cost of higher procedure-related risks and longer hospital stay.On the other hand,enteral stenting provides rapid clinical improvement,but have the limit of higher stent dysfunction rate due to tumor ingrowth and a subsequent need of frequent reinterventions.Recently,a third way has come from interventional endoscopic ultrasound,through the development of endoscopic ultrasound-guided gastroenterostomy technique with lumen-apposing metal stent.This new technique may ideally encompass the minimal invasiveness of an endoscopic procedure and the long-lasting effect of the surgical gastrojejunostomy,and brought encouraging results so far,even if prospective comparative trial are still lacking.In this Review,we described technical aspects and clinical outcomes of the above-cited therapeutic approaches,and discussed the open questions about the current management of MGOO. | Edoardo Troncone Alessandro Fugazza Annalisa Cappello Giovanna Del Vecchio Blanco Giovanni Monteleone Alessandro Repici Anthony Yuen Bun Teoh Andrea Anderloni | 2020 | World Journal of Gastroenterology2020，26，16： | 7 |
| 8 | Common immunologic mechanisms in inflammatory bowel disease and spondylarthropathies显示文摘Spondyloarthropathies(SpA) are commonly observed extra-intestinal manifestations of both Crohn's disease(CD) and ulcerative colitis(UC), the two major forms of inflammatory bowel diseases(IBD).However, the immunological link between these two clinical entities is still poorly understood.Several lines of evidence indicate that SpA may originate from the relocation to the joints of the immune process primarily induced in the gut.The transfer of the intestinal inflammatory process into the joints implicates that immune cells activated in the gut-draining lymph nodes can localize, at a certain point of the intestinal disease, either into the gut or into the joints.This is indicated by the over-lapping expression of adhesion molecules observed on the surface of intestinal and synovial endothelial cells during inflammation.Moreover bacterial antigens and HLA-B27 expression may be implicated in the reactivation of T cells at the articular level.Finally, accumulating evidence indicates that a T helper 17 cell-mediated immune response may contribute to IBD and IBD-related SpA with a crucial role played by tumor necrosis factor-α in CD and to a lesser extent in UC. | Massimo C Fantini Francesco Pallone Giovanni Monteleone | 2009 | World Journal of Gastroenterology2009，15，20： | 5 |
| 9 | Involvement of interleukin-15 and interleukin-21, two γ-chain-related cytokines, in celiac disease显示文摘Celiac disease (CD), an enteropathy caused by dietary gluten in genetically susceptible individuals, is histologically characterized by villous atrophy, crypt cell hyperplasia, and increased number of intra-epithelial lymphocytes. The nature of CD pathogenesis remains unclear, but recent evidence indicates that both innate and adaptive immune responses are necessary for the phenotypic expression and pathologic changes characteristic of CD. Extensive studies of molecules produced by immune cells in the gut of CD patients have led to identification of two cytokines, namely interleukin (IL)-15 and IL-21, which are thought to play a major role in orchestrating the mucosal inflammatory response in CD. Here we review the current knowledge of the expression and function of IL-15 and IL-21 in CD. | Daniela De Nitto Ivan Monteleone Eleonora Franzè Francesco Pallone Giovanni Monteleone | 2009 | World Journal of Gastroenterology2009，15，37： | 3 |
| 10 | Lumen-apposing metal stents for malignant biliary obstruction: Is this the ultimate horizon of our experience?显示文摘In the last years, endoscopic ultrasonography (EUS) has evolved from a purely diagnostic technique to a more and more complex interventional procedure, with the possibility to perform several type of therapeutic interventions. Among these, EUS-guided biliary drainage (BD) is gaining popularity as a therapeutic approach after failed endoscopic retrograde cholangiopancreatography in distal malignant biliary obstruction (MBO), due to the avoidance of external drainage, a lower rate of adverse events and re-interventions, and lower costs compared to percutaneous trans-hepatic BD. Initially, devices created for luminal procedures (e.g., luminal biliary stents) have been adapted to the new trans-luminal EUSguided interventions, with predictable shortcomings in technical success, outcome and adverse events. More recently, new metal stents specifically designed for transluminal drainage, namely lumen-apposing metal stents (LAMS), have been made available for EUS-guided procedures. An electrocautery enhanced delivery system (EC-LAMS), which allows direct access of the delivery system to the target lumen, has subsequently simplified the classic multi-step procedure of EUS-guided drainages. EUS-BD using LAMS and ECLAMS has been demonstrated effective and safe, and currently seems one of the most performing techniques for EUS-BD. In this Review, we summarize the evolution of the EUS-BD in distal MBO, focusing on the novelty of LAMS and analyzing the unresolved questions about the possible role of EUS as the first therapeutic option to achieve BD in this setting of patients. | Andrea Anderloni Edoardo Troncone Alessandro Fugazza Annalisa Cappello Giovanna Del Vecchio Blanco Giovanni Monteleone Alessandro Repici | 2019 | World Journal of Gastroenterology2019，25，29： | 3 |
| 11 | Proteinase activated-receptors-associated signaling in the control of gastric cancer显示文摘Gastric cancer(GC)is the fourth most common cancer in the world and the second cause of cancer-related death.Gastric carcinogenesis is a multifactorial process,in which environmental and genetic factors interact to activate multiple intracellular signals thus leading to uncontrolled growth and survival of GC cells.One such a pathway is regulated by proteinase activated-receptors(PARs),seven transmembrane-spanning domain G protein-coupled receptors,which comprise four receptors(i.e.,PAR-1,PAR-2,PAR-3,and PAR-4)activated by various proteases.Both PAR-1 and PAR-2 are over-expressed on GC cells and their activation triggers and/or amplifies intracellular pathways,which sustain gastric carcinogenesis.There is also evidence that expression of either PAR-1 or PAR-2 correlates with depth of wall invasion and metastatic dissemination and inversely with the overall survival of patients.Consistently,data emerging from experimental models of GC suggest that both these receptors can be important targets for therapeutic interventions in GC patients.In contrast,PAR-4levels are down-regulated in GC and correlate inversely with the aggressiveness of GC,thus suggesting a negative role of this receptor in the control of GC.In this article we review the available data on the expression and role of PARs in GC and discuss whether manipulation of PAR-driven signals may be useful for interfering with GC cell behavior. | Silvia Sedda Irene Marafini Roberta Caruso Francesco Pallone Giovanni Monteleone | 2014 | World Journal of Gastroenterology2014，20，34： | 3 |

| 18 | Molecular basis of the potential of mesalazine to prevent colorectal cancer显示文摘Patients with ulcerative colitis (UC) and Crohn's disease (CD) are at increased risk for developing colorectal cancer (CRC), and this is believed to be a result of chronic inflammation. Although conclusive evidence is still missing, both epidemiological and experimental observations suggest that certain drugs used to treat inflammation, such as mesalazine, can reduce the incidence of colitis-associated CRC. Therefore, in recent years, several studies have been conducted to dissect the mechanisms by which mesalazine interferes with CRC cell growth and survival. This review summarizes the current information on the molecular mechanisms that underlie the antineoplastic action of mesalazine. | Carmine Stolfi Roberto Pellegrini Eleonora Franzè Francesco Pallone Giovanni Monteleone | 2008 | World Journal of Gastroenterology2008，14，28： | 1 |
