Xu R, Du W, Yang Q, Du A. ITGB2 related to immune cell infiltration as a potential therapeutic target of inflammatory bowel disease using bioinformatics and functional research. J Cell Mol Med 2024; 28:e18501. [PMID: 39088353 PMCID: PMC11293422 DOI: 10.1111/jcmm.18501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 05/23/2024] [Accepted: 06/08/2024] [Indexed: 08/03/2024] Open
Abstract
Inflammatory bowel disease (IBD) is a chronic systemic inflammatory condition regarded as a major risk factor for colitis-associated cancer. However, the underlying mechanisms of IBD remain unclear. First, five GSE data sets available in GEO were used to perform 'batch correction' and Robust Rank Aggregation (RRA) to identify differentially expressed genes (DEGs). Candidate molecules were identified using CytoHubba, and their diagnostic effectiveness was predicted. The CIBERSORT algorithm evaluated the immune cell infiltration in the intestinal epithelial tissues of patients with IBD and controls. Immune cell infiltration in the IBD and control groups was determined using the least absolute shrinkage selection operator algorithm and Cox regression analysis. Finally, a total of 51 DEGs were screened, and nine hub genes were identified using CytoHubba and Cytoscape. GSE87466 and GSE193677 were used as extra data set to validate the expression of the nine hub genes. CD4-naïve T cells, gamma-delta T cells, M1 macrophages and resting dendritic cells (DCs) are the main immune cell infiltrates in patients with IBD. Signal transducer and activator of transcription 1, CCR5 and integrin subunit beta 2 (ITGB2) were significantly upregulated in the IBD mouse model, and suppression of ITGB2 expression alleviated IBD inflammation in mice. Additionally, the expression of ITGB2 was upregulated in IBD-associated colorectal cancer (CRC). The silence of ITGB2 suppressed cell proliferation and tumour growth in vitro and in vivo. ITGB2 resting DCs may provide a therapeutic strategy for IBD, and ITGB2 may be a potential diagnostic marker for IBD-associated CRC.

Antibiotics (Basel) 2024; 13:267. [PMID: 38534702 DOI: 10.3390/antibiotics13030267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 03/14/2024] [Accepted: 03/15/2024] [Indexed: 03/28/2024] Open
Abstract
Helicobacter pylori (H. pylori) infection is a prominent entity within human infectious diseases which cause chronic gastritis, peptic ulcers, gastric malignancies, and extragastric disorders. Its persistent colonization can lead to a systemic inflammatory cascade, potentially instigating autoimmune responses and contributing to the pathogenesis of autoimmune diseases. While the specific etiopathogenesis of inflammatory bowel diseases (IBDs) is still unknown, it is widely recognized that immunological, genetic, and environmental factors are implicated. Various bacterial and viral pathogens have been implicated in the pathogenesis of IBDs. Numerous studies suggest a correlation between H. pylori infection and IBDs. While subject to debate, this link suggests that the bacterium's presence somehow impacts the progression of IBDs by modifying the diversity of the gut microbiota, consequently altering local chemical profiles and disrupting the pattern of gut immune response. However, epidemiological evidence indicates a protective role of H. pylori infection against the onset of autoimmune diseases. Additionally, laboratory findings demonstrate H. pylori's capacity to promote immune tolerance and restrict inflammatory reactions. The aim of this review is to elucidate the proposed mechanisms and confounding factors that underlie the potential association between H. pylori infection and IBDs.

Abstract
Chronic inflammatory enteropathy (CIE) in dogs, a spontaneous model of human inflammatory bowel disease (IBD), is associated with a high rate of cobalamin deficiency. The etiology of hypocobalaminemia in human IBD and canine CIE remains unknown, and compromised intestinal uptake of cobalamin resulting from ileal cobalamin receptor deficiency has been proposed as a possible cause. Here, we evaluated the intestinal expression of the cobalamin receptor subunits, amnionless (AMN) and cubilin (CUBN), and the basolateral efflux transporter multi-drug resistance protein 1 (MRP1) in 22 dogs with CIE in comparison to healthy dogs. Epithelial CUBN and AMN levels were quantified by confocal laser scanning microscopy using immunohistochemistry in endoscopic ileal biopsies from dogs with (i) CIE and normocobalaminemia, (ii) CIE and suboptimal serum cobalamin status, (iii) CIE and severe hypocobalaminemia, and (iv) healthy controls. CUBN and MRP1 expression was quantified by RT-qPCR. Receptor expression was evaluated for correlation with clinical patient data. Ileal mucosal protein levels of AMN and CUBN as well as mRNA levels of CUBN and MRP1 were significantly increased in dogs with CIE compared to healthy controls. Ileal cobalamin receptor expression was positively correlated with age, clinical disease activity index (CCECAI) score, and lacteal dilation in the ileum, inversely correlated with serum folate concentrations, but was not associated with serum cobalamin concentrations. Cobalamin receptor downregulation does not appear to be the primary cause of hypocobalaminemia in canine CIE. In dogs of older age with severe clinical signs and/or microscopic intestinal lesions, intestinal cobalamin receptor upregulation is proposed as a mechanism to compensate for CIE-associated hypocobalaminemia. These results support oral supplementation strategies in hypocobalaminemic CIE patients.

Crosstalk between alternative splicing and inflammatory bowel disease: Basic mechanisms, biotechnological progresses and future perspectives. Clin Transl Med 2023; 13:e1479.

Abstract
BACKGROUND Alternative splicing (AS) is an omnipresent regulatory mechanism of gene expression that enables the generation of diverse splice isoforms from a single gene. Recently, AS events have gained considerable momentum in the pathogenesis of inflammatory bowel disease (IBD). METHODS Our review has summarized the complex process of RNA splicing, and firstly highlighted the potential involved molecules that target aberrant splicing events in IBD. The quantitative transcriptome analyses such as microarrays, next-generation sequencing (NGS) for AS events in IBD have been also discussed. RESULTS Available evidence suggests that some abnormal splicing RNAs can lead to multiple intestinal disorders during the onset of IBD as well as the progression to colitis-associated cancer (CAC), including gut microbiota perturbations, intestinal barrier dysfunctions, innate/adaptive immune dysregulations, pro-fibrosis activation and some other risk factors. Moreover, current data show that the advanced technologies, including microarrays and NGS, have been pioneeringly employed to screen the AS candidates and elucidate the potential regulatory mechanisms of IBD. Besides, other biotechnological progresses such as the applications of third-generation sequencing (TGS), single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST), will be desired with great expectations. CONCLUSIONS To our knowledge, the current review is the first one to evaluate the potential regulatory mechanisms of AS events in IBD. The expanding list of aberrantly spliced genes in IBD along with the developed technologies provide us new clues to how IBD develops, and how these important AS events can be explored for future treatment.

Immune response modulation in inflammatory bowel diseases by Helicobacter pylori infection. World J Gastroenterol 2023; 29:4604-4615. [PMID: 37662864 PMCID: PMC10472898 DOI: 10.3748/wjg.v29.i30.4604] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 07/01/2023] [Accepted: 07/24/2023] [Indexed: 08/10/2023] Open
Abstract
Many studies point to an association between Helicobacter pylori (H. pylori) infection and inflammatory bowel diseases (IBD). Although controversial, this association indicates that the presence of the bacterium somehow affects the course of IBD. It appears that H. pylori infection influences IBD through changes in the diversity of the gut microbiota, and hence in local chemical characteristics, and alteration in the pattern of gut immune response. The gut immune response appears to be modulated by H. pylori infection towards a less aggressive inflammatory response and the establishment of a targeted response to tissue repair. Therefore, a T helper 2 (Th2)/macrophage M2 response is stimulated, while the Th1/macrophage M1 response is suppressed. The immunomodulation appears to be associated with intrinsic factors of the bacteria, such as virulence factors - such oncogenic protein cytotoxin-associated antigen A, proteins such H. pylori neutrophil-activating protein, but also with microenvironmental changes that favor permanence of H. pylori in the stomach. These changes include the increase of gastric mucosal pH by urease activity, and suppression of the stomach immune response promoted by evasion mechanisms of the bacterium. Furthermore, there is a causal relationship between H. pylori infection and components of the innate immunity such as the NLR family pyrin domain containing 3 inflammasome that directs IBD toward a better prognosis.

Abstract
Although gut microbiome dysbiosis has been associated with inflammatory bowel disease (IBD), the relationship between the oral microbiota and IBD remains poorly understood. This study aimed to identify unique microbiome patterns in saliva from IBD patients and explore potential oral microbial markers for differentiating Crohn's disease (CD) and ulcerative colitis (UC). A prospective cohort study recruited IBD patients (UC: n = 175, CD: n = 127) and healthy controls (HC: n = 100) to analyze their oral microbiota using 16S rRNA gene sequencing. Machine learning models (sparse partial least squares discriminant analysis (sPLS-DA)) were trained with the sequencing data to classify CD and UC. Taxonomic classification resulted in 4041 phylotypes using Kraken2 and the SILVA reference database. After quality filtering, 398 samples (UC: n = 175, CD: n = 124, HC: n = 99) and 2711 phylotypes were included. Alpha diversity analysis revealed significantly reduced richness in the microbiome of IBD patients compared to healthy controls. The sPLS-DA model achieved high accuracy (mean accuracy: 0.908, and AUC: 0.966) in distinguishing IBD vs. HC, as well as good accuracy (0.846) and AUC (0.923) in differentiating CD vs. UC. These findings highlight distinct oral microbiome patterns in IBD and provide insights into potential diagnostic markers.

Abstract
Background & aims The faecal immunochemical test (FIT), a non-invasive test for screening colorectal cancer (CRC), is being increasingly understood to reflect heightened inflammation. We aimed to investigate the association between abnormal FIT results and onset of inflammatory bowel disease (IBD), a disease characterized with chronic gut mucosal inflammation. Methods Participants in the Korean National Cancer Screening Program for CRC between 2009-2013 were analysed and divided into positive and negative FIT result groups. The incidence rates of IBD after screening were calculated after excluding cases of haemorrhoids, CRC, and IBD at baseline. Cox proportional hazard analyses were used to identify independent risk factors for IBD occurrence during follow-up, and 1:2 propensity score matching was performed as a sensitivity analysis. Results In total, 229,594 and 815,361 participants were assigned to the positive and negative FIT result groups, respectively. The age- and sex-adjusted incidence rates of IBD in participants with positive and negative test results were 1.72 and 0.50 per 10,000 person-years, respectively. Adjusted Cox analysis revealed that FIT positivity was associated with a significantly higher risk of IBD (hazard ratio 2.93, 95% confidence interval: 2.46, 3.47, P <.001), which was consistent for both disease subtypes of ulcerative colitis and Crohn's disease. The results of Kaplan-Meier analysis in the matched population yielded identical findings. Conclusions Abnormal FIT results could be a preceding sign of incident IBD in the general population. Those with positive FIT results and suspected IBD symptoms could benefit from regular screening for early disease detection.

Abstract
Polysaccharides show protective effects on intestinal barrier function due to their effectiveness in mitigating oxidative damage, inflammation and probiotic effects. Little has been known about the effects of polysaccharides from Artocarpus heterophyllus Lam. pulp (jackfruit, JFP-Ps) on intestinal barrier function. This study aimed to investigate the effects of JFP-Ps on intestinal barrier function in high fat diet-induced obese rats. H&E staining and biochemical analysis were performed to measure the pathological and inflammatory state of the intestine as well as oxidative damage. Expression of the genes and proteins associated with intestinal health and inflammation were analyzed by RT-qPCR and western blots. Results showed that JFP-Ps promoted bowel movements and modified intestinal physiochemical environment by lowering fecal pH and increasing fecal water content. JFP-Ps also alleviated oxidative damage of the colon, relieved intestinal colonic inflammation, and regulated blood glucose transport in the small intestine. In addition, JFP-Ps modified intestinal physiological status through repairing intestinal mucosal damage and increasing the thickness of the mucus layer. Furthermore, JFP-Ps downregulated the inflammatory genes (TNF-α, IL-6) and up-regulated the free fatty acid receptors (GPR41 and GPR43) and tight junction protein (occludin). These results revealed that JFP-Ps showed a protective effect on intestinal function through enhancing the biological, mucosal, immune and mechanical barrier functions of the intestine, and activating SCFAs-GPR41/GPR43 related signaling pathways. JFP-Ps may be used as a promising phytochemical to improve human intestinal health.

Abstract
Inflammatory bowel disease (IBD) is a chronic disorder associated with the inflammation in the digestive tract. The exact cause of IBD is unknown; nevertheless, in IBD, the homeostasis of key regulatory factors involved in intestinal immunity has been documented to be disrupted. Despite the lack of a viable treatment for IBD, synthetic drugs and monoclonal antibodies are currently used to treat it. However, these treatments have side effects, and the high relapse rate limits their usage. Dietary polyphenols constitute a great variety of compounds and have shown an array of biological properties. Resveratrol is a natural polyphenol found in grapevines and berries. The therapeutic ability of resveratrol against IBD is amply demonstrated in many in vivo studies. Resveratrol can interact with several molecular targets (Nf-kB, SIRT1, mTOR, HIF-1α, miRNAs, and TNF-α) and effectively prevent/ alleviate IBD symptoms with promising results. Although resveratrol has profound anti-inflammatory properties against IBD, its therapeutic employment is limited due to its low water solubility, less chemical stability, less bioavailability, and rapid metabolism in vivo. Hence, resveratrol encapsulation using different carries and its controlled release has become a promising strategy to overcome limitations. Herein, we meticulously review, talk-over the anti-inflammatory effect and mechanisms of resveratrol in IBD. We further provide the latest information on resveratrol formulations and nano-delivery systems used in oral delivery of resveratrol for the treatment of IBD and offer our view on future research on resveratrol in IBD treatment.

Abstract
Diosgenin (DIO) is a kind of steroid sapogenin derived from natural plants. It exerts strong anti-infection, antiallergy, antiviral, and antishock pharmacological properties. In this article, the protective effects of DIO against dextran sulfate sodium (DSS)-induced colitis in mice were researched. Compared with the 2.5% DSS treatment group, 15 mg/kg body weight of diosgenin alleviated colitis disease, evidenced by the increased body weight, the decrease in the disease activity index, and the histological scores. Furthermore, 16S rRNA high-throughput sequencing results demonstrated that DIO improved the colon homeostasis through modulating the gut microbiota, including increases in the relative abundance of several probiotic bacteria, such as Prevotellaceae (from 1.4% to 5.8%), Lactobacillus (from 12.3% to 29.7%), Mucispirillum (from 0.07% to 0.49%), and decreases in the pathogenic bacteria, such as Streptococcus (from 1.6% to 0.6%) and Pseudomonadaceae (from 0.004% to 0%). In addition, the concentration of gut microbial metabolites, total short-chain fatty acids (SCFAs), acetic acid, and propionic acid were significantly increased after DIO supplementation. In conclusion, our findings suggested that DIO attenuates DSS-induced colitis in mice by means of modulating imbalanced gut microbiota and increases in SCFA generation.

Abstract
BACKGROUND Chromofungin (CHR: chromogranin-A 47-66) is a chromogranin-A derived peptide with anti-inflammatory and anti-microbial properties. Ulcerative colitis (UC) is characterized by a colonic decrease of CHR and a dysregulation of dendritic CD11c+ cells.
AIM To investigate the association between CHR treatment and dendritic cells (DCs)-related markers in different immune compartments in colitis.
METHODS A model of acute UC-like colitis using dextran sulphate sodium (DSS) was used in addition to biopsies collected from UC patients.
RESULTS Intrarectal CHR treatment reduced the severity of DSS-induced colitis and was associated with a significant decrease in the expression of CD11c, CD40, CD80, CD86 and interleukin (IL)-12p40 in the inflamed colonic mucosa and CD11c, CD80, CD86 IL-6 and IL-12p40 within the mesenteric lymph nodes and the spleen. Furthermore, CHR treatment decreased CD80 and CD86 expression markers of splenic CD11c+ cells and decreased NF-κB expression in the colon and of splenic CD11c+ cells. In vitro, CHR decreased CD40, CD80, CD86 IL-6 and IL-12p40 expression in naïve bone marrow-derived CD11c+ DCs stimulated with lipopolysaccharide. Pharmacological studies demonstrated an impact of CHR on the NF-κB pathway. In patients with active UC, CHR level was reduced and showed a negative linear relationship with CD11c and CD86.
CONCLUSION CHR has protective properties against intestinal inflammation via the regulation of DC-related markers and CD11c+ cells. CHR could be a potential therapy of UC.

Abstract
Introduction Ste20-related protein proline/alanine-rich kinase (SPAK) affects cell proliferation, differentiation, and transformation, and sodium and chloride transport in the gut. However, its role in gut injury pathogenesis is unclear. Objective We determined the role of SPAK in chemotherapy-induced intestinal mucositis using in vivo and in vitro models. Methods Using SPAK-knockout (KO) mice, we evaluated the severity of intestinal mucositis induced by 5-fluorouracil (5-FU) by assessing body weight loss, histological changes in the intestinal mucosa, length of villi in the small intestine, pro-inflammatory cytokine levels, proliferative indices, and apoptotic indices. We also evaluated changes in gut permeability and tight junction-associated protein expression. Changes in cell permeability, proliferation, and apoptosis were assessed in SPAK siRNA-transfected 5FU-treated IEC-6 cells. Results 5-FU-treated SPAK-KO mice exhibited milder intestinal mucositis, reduced pro-inflammatory cytokine expression, increased villus length, good maintenance of proliferative indices of villus cells, decreased apoptotic index of enterocytes, reduced gut permeability, and restoration of tight junction protein expression (vs. 5-FU-treated wild-type mice). Under in vitro conditions, siRNA-mediated SPAK-knockdown in IEC-6 cells decreased cell permeability and maintained homeostasis following 5-FU treatment. Conclusion SPAK deficiency attenuated chemotherapy-induced intestinal mucositis by modulating gut permeability and tight junction-associated protein expression and maintaining gut homeostasis in murine small intestinal tissues following gut injury. The expression of SPAK may influence the pathogenesis of chemotherapy-induced intestinal mucositis.

Abstract
The intestinal mucosal immune barrier protects the host from the invasion of foreign pathogenic microorganisms. Immune cells and cytokines in the intestinal mucosa maintain local and systemic homeostasis by participating in natural and adaptive immunity. Deficiency of the intestinal mucosal immune barrier is associated with a variety of intestinal illnesses. Exosomes are phospholipid bilayer nanovesicles that allow cell-cell communication by secreting physiologically active substances including proteins, lipids, transcription factors, mRNAs, micro-RNAs (miRNAs), and long noncoding RNAs (lncRNAs). Exosomal lncRNAs are involved in immune cell differentiation and the modulation of the immune response. This review briefly introduces the potential role of exosomal lncRNAs in the intestinal mucosal immune barrier and discusses their relevance to intestinal illnesses.

Abstract
The present study aimed to evaluate the efficacy of flaxseed supplementation in the management of metabolic syndrome (MetS)-related parameters among the patients with mild-to-moderate ulcerative colitis (UC). A randomized controlled clinical trial was conducted on 70 patients with UC. Participants were randomized in the intervention group, which received 30 g/day ground flaxseed powder or control group. Anthropometric and biochemical variables were assessed at the beginning and end of 12 weeks of intervention. Of the 70 patients enrolled in this study, 64 subjects were included in the final analysis. From baseline to 12 weeks' intervention, flaxseed supplementation resulted in a significant reduction in the serum concentration of insulin (p < .001), HOMA-IR (p < .001), triglyceride (p = .001), total cholesterol (p < .001), and significant increase in the serum levels of HDL (p = .008). Also, we found a significant improvement in the SCCAI score (p < .001), TNF-α (p = .03), and CRP (p < .001) following the flaxseed supplementation. However, we not observed any significant differences between two groups regarding the body weight, BMI, waist circumferences, systolic, and diastolic blood pressure (p > .05). Overall, 12 weeks of flaxseed supplementation resulted in greater improvement in the some MetS-related parameters.

Abstract
Ulcerative colitis (UC) is a widespread inflammatory bowel disease that causes long-lasting inflammation and ulcers in the colon and rectum. In the inflamed tissue of patients with UC, the tight junctions are disrupted and large amounts of pro-inflammatory cytokines are produced, resulting in immune dysregulation. The expression of Nur77 is significantly reduced in the colon of inflammatory bowel disease, while Nur77 deficiency increases the susceptibility to DSS-induced colitis. Here, we report that Gly-Pro-Ala (GPA) peptide isolated from fish skin gelatin hydrolysate can significantly alleviate intestinal inflammation and damage caused by DSS-induced mice colitis. Besides maintaining the intestinal epithelial barrier, GPA alleviates intestinal inflammation and oxidative stress by inhibiting NF-κB activation. Interestingly, GPA binds to the ligand-binding domain of Nur77 and stimulates its autotranscriptional activity to enhance its expression in intestinal epithelial cells. Furthermore, GPA activates the promoter of IκBα to increase its expression, resulting in the abolishment of the NF-κB pathway. In contrast, the inhibitory effects of GPA on colitis are abolished in Nur77-/- mice. Our results suggest that as a Nur77 modulator, GPA may be applied to the prevention of intestinal inflammation.

Abstract
Inflammatory bowel disease (IBD) is a chronic and progressive disorder with destructive inflammation in the gastrointestinal tract (GIT). Biologics have changed the management of IBD, but have serious limitations, which is associated with their systemic administration via injection. Oral administration is the most accepted route of drug administration. However, the physiological barriers of the GIT pose significant challenges for oral administration of biologics, making this route of administration currently unavailable. The status of tissue barriers to oral drug delivery is altered in IBD. This may bring more challenges, but also present opportunities for oral delivery of biologics. This article provides an overview of disease-induced alterations of GIT barriers in IBD and discusses challenges, opportunities and commonly-utilised strategies for oral delivery of complex therapeutics, including biologics and nanomedicines.

Abstract
Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory disease affecting the colon, and its incidence is rising worldwide. Nur77, belongs to the NR4A subfamily of nuclear hormone receptors, plays a critical role in controlling the pathology of colitis. The aim of this study is to investigate the protection effect and mechanism of Gly-Pro-Ala (GPA) peptide, isolated from fish skin gelatin hydrolysate, in a mouse model of dextran sulfate sodium- (DSS-) induced colitis and intestinal epithelial cells (IECs) stimulated by lipopolysaccharide (LPS). In vivo, GPA treatment alleviates DSS-induced weight loss, disease activity index (DAI) increase, colon length shortening, and colonic pathological damage. Production of proinflammatory cytokines, ROS, and MDA is significantly decreased by GPA treatment. In vitro, GPA significantly inhibits proinflammatory cytokine production, cytotoxicity, ROS, and MDA in IECs. Furthermore, GPA induces autophagy to suppress inflammation and oxidative stress. GPA promotes Nur77 translocation from the nucleus to mitochondria where it facilitates Nur77 interaction with TRAF6 and p62, leading to the induction of autophagy. In addition, GPA contributed to the maintenance of tight junction architecture in vivo and in vitro. Taken together, GPA, as a Nur77 modulator, could exert anti-inflammatory and antioxidant effects by inducing autophagy in IECs, suggesting that GPA may be promising for the prevention of colitis.

Abstract
Dextrans are homopolysaccharides of D-glucose units produced by lactic acid bacteria. They have several technological applications and potential utilisation in positively modulating gut microbiota is attracting increasing attention. Whereas the prebiotic activity of low polymerisation degree (DP) dextrans has been established, high DP dextrans still deserve deeper investigation. In the present study, a long linear chain dextran produced by Weissella cibaria was compared to inulin with regards to the growth of specific health-related taxa and to the production of organic acids in pH-controlled batch cultures of intestinal microbiota. qPCR quantification of Lactobacillus, Bifidobacterium, Prevotella, Bacteroides fragilis, and Faecalibacterium prausnitzii revealed differences in their relative abundance, depending on the carbon source, that reflected the pattern of fermentation products determined by HPLC. Dextran mainly enhanced the relative amount of Prevotella and Bacteroides, consistently with a favourable acetate-propionate ratio suggesting a promising utilisation as functional ingredient in the food industry.

Abstract
Inflammatory bowel disease (IBD) is a chronic and life-threating inflammatory disease of gastroenteric tissue characterized by episodes of intestinal inflammation. The pathogenesis of IBD is complex. Recent studies have greatly improved our knowledge of the pathophysiology of IBD, leading to great advances in the treatment as well as diagnosis of IBD. In this review, we have systemically reviewed the pathogenesis of IBD and highlighted recent advances in host genetic factors, gut microbiota, and environmental factors and, especially, in abnormal innate and adaptive immune responses and their interactions, which may hold the keys to identify novel predictive or prognostic biomarkers and develop new therapies.

Abstract
Levan is a fructose polymer with diverse applications in the food and medical industries. In this study, levansucrase from Rahnella aquatilis (RaLsrA) was hyper-secreted using a Saccharomyces cerevisiae protein secretion system. An optimal secretion signal, a translation fusion partner (TFP) containing an N-terminal 98 amino acid domain from a mitochondrial inner membrane protein, UTH1, was employed to secrete approximately 50 U/mL of bioactive RaLsrA into culture media with 63% secretion efficiency by fed-batch fermentation. Although the purified RaLsrA was useful for enzymatic conversion of high-molecular-weight levan of approximately 3.75 × 106 Da, recombinant yeast secreting RaLsrA could produce levan more efficiently by microbial fermentation. In a 50-L scale fermenter, 76-g/L levan was directly converted from 191-g/L sucrose by recombinant yeast cells, attaining an 80% conversion yield and 3.17-g/L/h productivity. Thus, we developed a cost-effective and industrially applicable production system for food-grade levan.

Abstract
Gene vectors for oral delivery encounter harsh conditions throughout the gastrointestinal tract, and the continuous peristaltic activity can quickly remove the vectors, leading to inefficient intestinal permeation. Therefore, vectors have demanding property requirements, such as stability under various pH and, more importantly, efficient uptake in different intestinal segments. In this study, a functional polymer, cholesterol-grafted poly(β-amino ester) (poly[hexamethylene diacrylate-β-(5-amino-1-pentanol)] (CH-PHP)), is synthesized and electrostatically interacted with plasmid DNA to form a CH-PHP/DNA complex (CPNC). This complex is designed to target the Niemann-Pick C1-like receptor, a cholesterol receptor, to improve oral gene delivery efficacy. With the presence of cholesterol, CH-PHP shows mitigated cytotoxicity, enhanced enzyme resistance, and improved gene condensing ability. CPNC further contributes to ≈43.1- and 2.3-fold increases in luciferase expression in Caco-2 cells compared with PNC and Lipo 2000/DNA complexes, respectively. In addition, the in vivo transfection efficacy of CPNC is ≈4.1-, 2.1-, and 1.6-fold higher than that of Lipo 2000/DNA complexes in rat duodenum, jejunum, and ileum, respectively. Therefore, CPNC may be a promising delivery vector for gene delivery, and using a cholesterol-specific endocytic pathway can be a novel approach to achieve efficient oral gene transfection.

Abstract
BACKGROUND There is little information regarding the use of biologics in Inflammatory Bowel Disease (IBD) patients in Japan. The aim of this study was to determine the factors associated with the use of biologics in the treatment of Japanese patients with IBD. METHODS An online survey was conducted among Japanese patients with IBD (n = 1035). Socioeconomic as well as treatment related information was collected. Logistic regression was applied to analyze the determinants of biologic treatment. RESULTS Younger age (≤ 40 years vs. > 65 years; OR:0.24), time since diagnosis (< 2 years vs. < 15 years; OR: 4.16), surgical history (OR:1.98) and visiting university hospitals (university hospitals vs. clinics; OR: 0.47) were associated with biologic treatment for Japanese IBD patients. CONCLUSIONS Currently, biologics have been used in younger IBD patients which may give rise to the presence of an age bias in biologic treatment. Further studies are required to confirm these results and to define appropriate IBD patients who should be treated with biologic agent.

Abstract
The beneficial effects exerted by probiotics in inflammatory bowel disease (IBD) are well known, although their exact mechanisms have not been fully elucidated, and only few studies have focused on their impact on selected miRNAs and the gut microbiota composition. Therefore, our aim was to correlate the intestinal anti-inflammatory activity of the probiotic Saccharomyces boulardii in the dextran sodium sulphate (DSS) model of mouse colitis and the changes induced in miRNA expression and gut microbiota populations. Probiotic was given orally (5×109 CFU) to C57BL/6 mice for 26 days. After 2 weeks, the colitis was induced adding DSS to the drinking water. Mice were scored daily using a Disease Activity Index (DAI). After sacrifice, the colonic specimens were evaluated by determining the expression of inflammatory markers and micro-RNAs by qRT-PCR. Moreover, changes in microbiota populations were evaluated by pyrosequencing. Probiotic ameliorated the colonic damage induced by DSS, as evidenced by lower DAI values and colonic weight/length compared with untreated mice. The treatment modified the colonic expression of different inflammatory markers and the epithelial integrity proteins, and induced changes in micro-RNAs expression. Moreover, microbiota characterization showed that probiotic treatment increased bacterial diversity, thus ameliorating the dysbiosis produced by DSS-colitis. Saccharomyces boulardii exerted intestinal anti-inflammatory effects in DSS-mouse colitis, through the modulation in the immune response, involving modification of altered miRNA expression, being associated to the improvement of the inflammation-associated dysbiosis in the intestinal lumen, which could be of great interest to control the complex pathogenesis of IBD.

Abstract
The beneficial effects of probiotics on immune-based pathologies such as inflammatory bowel disease (IBD) have been well reported. However, their exact mechanisms have not been fully elucidated. Few studies have focused on the impact of probiotics on the composition of the colonic microbiota. The aim of the present study was to correlate the intestinal anti-inflammatory activity of the probiotic Escherichia coli Nissle 1917 (EcN) in the dextran sodium sulfate (DSS) model of mouse colitis with the changes induced in colonic microbiota populations. EcN prevented the DSS-induced colonic damage, as evidenced by lower disease activity index (DAI) values and colonic weight/length ratio, when compared with untreated control mice. The beneficial effects were confirmed biochemically, since the probiotic treatment improved the colonic expression of different cytokines and proteins involved in epithelial integrity. In addition, it restored the expression of different micro-RNAs (miR-143, miR-150, miR-155, miR-223, and miR-375) involved in the inflammatory response that occurs in colitic mice. Finally, the characterization of the colonic microbiota by pyrosequencing showed that the probiotic administration was able to counteract the dysbiosis associated with the intestinal inflammatory process. This effect was evidenced by an increase in bacterial diversity in comparison with untreated colitic mice. The intestinal anti-inflammatory effects of the probiotic EcN were associated with an amelioration of the altered gut microbiome in mouse experimental colitis, especially when considering bacterial diversity, which is reduced in these intestinal conditions. Moreover, this probiotic has shown an ability to modulate expression levels of miRNAs and different mediators of the immune response involved in gut inflammation. This modulation could also be of great interest to understand the mechanism of action of this probiotic in the treatment of IBD.

Abstract
In recent years, using genetic engineering and bioengineering techniques, Bifidobacterium as a carrier to express specific functions of the protein or polypeptide, has become a new treatment for disease. Ulcerative colitis (UC) is a type of inflammatory bowel diseases (IBD). Although the cause of this inflammatory disorder is still unknown, a large amount of evidence suggests that ulcerative colitis is associated with increased activity of reactive oxygen species (ROS), manganese superoxide dismutase (MnSOD) is a kind of superoxide dismutase (SOD) has been demonstrated to play a key role in the pathophysiology of colitis. Here, we explored the Bifidobacterium as a drug delivery system to orally deliver a potent anti-inflammatory but poor penetration and stability antioxidant enzymes human MnSOD, transported into cells by a penetratin PEP-1. We constructed an expression vector expressing PEP-1-hMnSOD fusion protein, and successfully expressed hMnSOD fusion protein in engineered Bifidobacterium. Then we identified the bioactivity of engineered Bifidobacterium in LPS-induced inflammatory cell model. Finally, we used Bifidobacterium expressing PEP-1-hMnSOD fusion protein against DSS-induced ulcerative colitis mice. B. longum-PEP-1-rhMnSOD can successfully express rhMnSOD in the colon. We found that levels of inflammatory cytokines TNF-α, IL-1β, IL-6 and IL-8 as well as histological damage in colonic tissues showed that engineered Bifidobacterium effectively reduced dextran sulfate sodium(DSS)-induced ulcerative colitis, we also tested the MPO, verified the above conclusions. These results suggest that oral Bifidobacterium expressing PEP-1-hMnSOD fusion protein can be treated as a new method of UC treatment.

Abstract
AIM AND OBJECTIVES Hirschsprung-associated enterocolitis (HAEC) continues to be an important cause of morbidity in patients with Hirschsprung's disease (HSCR). HAEC can occur at any time during the course of the disease. The reported incidence of HAEC before surgery ranges from 6 to 50%, and after surgery, it ranges from 2 to 35%. HAEC and inflammatory bowel disease (IBD) have similar clinical presentation including diarrhea, hematochezia, and abdominal pain. In recent years, isolated cases of IBD have been reported in patients who had surgical treatment for HSCR. The exact pathogenesis of HAEC or IBD is not known. However, both conditions are characterized by an abnormal intestinal mucosal barrier function, which may be a common pathway. The purpose of this meta-analysis was to determine the clinical presentation and outcome in patients with HSCR who developed IBD after pull-through operation. MATERIALS AND METHODS A systematic literature search for relevant articles was performed in four databases using the combinations of the following terms "inflammatory bowel disease", "Crohn/Crohn's disease", "ulcerative colitis", and "Hirschsprung disease/Hirschsprung's disease" for studies published between 1990 and 2017. The relevant cohorts of HSCR associated with IBD were systematically searched for clinical presentation and outcomes. RESULTS 14 studies met defined inclusion criteria, reporting a total of 66 patients who had HSCR associated with IBD. Mean age at first operation for HSCR was 5.8 months, mean age at diagnosis of IBD was 7.7 years, and the majority of patients were male (73%). The extent of aganglionosis was total colonic aganglionosis in 41% of patients, long segment in 45%, and rectosigmoid in 14%. The majority of patients underwent a Duhamel procedure (84%) for HSCR. The distribution of IBD was Crohn's disease in 72.3% of patients, ulcerative colitis in 16.9%, and others in 10.8%. Eight articles (47 patients) reported about HAEC, and 22 patients (47%) had experienced HAEC after surgery for HSCR. CONCLUSION Male patients with extensive colonic aganglionosis who continue to suffer from postoperative HAEC after a Duhamel procedure are more susceptible to develop IBD. Recognition of IBD may be important in the long-term follow-up of HSCR patients who have had postoperative HAEC.

Abstract
BACKGROUND The aim of this study was to investigate the effect of anti-TNF therapy on glucose and lipid metabolism in nondiabetic, nonobese patients with inflammatory bowel disease (IBD). PATIENTS AND METHODS We studied 44 patients with IBD, without a known history of diabetes. Three of the patients were diagnosed with overt diabetes and were excluded. Eighteen of the remaining patients (9 M/9 F, 33.6 ± 8.8 years) were on anti-TNF therapy for longer than 1 year, while 23 patients (16 M/7 F, 38.7 ± 12.5 years) were treated with aminosalicylates (AMSs). Twelve of the patients from the second group were then treated with anti-TNF and reassessed 6 months later. Fasting glucose, insulin, c-peptide, HbA1c, lipid, CRP, and fibrinogen levels were determined, and HOMA-IR index was calculated in all patients. RESULTS Patients from the two therapy groups were matched for age and BMI and were not obese. We did not find any differences between patients from the two therapy groups regarding fasting glucose, c-peptide, HbA1c, total cholesterol, HDL, LDL, triglycerides, CRP, and HOMA-IR index. In patients who were treated for 6 months with anti-TNF, a statistically significant decrease in insulin (before 15.5 ± 5.9 versus after 9.9 ± 2.9 μIU/ml, p = 0.042) and c-peptide (before 2.4 ± 1 versus after 1.3 ± 0.4 ng/ml, p = 0.030) levels as well as the HOMA-IR index (before 4.2 ± 1.9 versus after 2.2 ± 0.9, p = 0.045) was observed, without any changes in weight, BMI, glucose, HbA1c, lipid, CRP, and fibrinogen levels. CONCLUSION Anti-TNF therapy exerts a favorable effect on insulin sensitivity, while it has no effect on lipid levels in nondiabetic, nonobese patients with inflammatory bowel disease.

Abstract
The inflammatory bowel diseases (IBDs), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory conditions of the gastrointestinal tract and involve a complicated reciprocity of environmental, genetic, and immunologic factors. Despite substantial advances in the foundational understanding of the immunological pathogenesis of IBD, the detailed mechanism of the pathological progression in IBD remains unknown. In addition to Th1/Th2 cells, whose role in IBD has been previously well defined, recent evidence indicates that Th17 cells and Tregs also play a crucial role in the development of IBD. Diets which contain excess sugars, salt, and fat may also be important actors in the pathogenesis of IBD, which may be the cause of high IBD incidence in western developed and industrialized countries. Up until now, the reason for the variance in prevalence of IBD between developed and developing countries has been unknown. This is partly due to the increasing popularity of western diets in developing countries, which makes the data harder to interpret. The enterocrinins glucagon-like peptides (GLPs), including GLP-1 and GLP-2, exhibit notable benefits on lipid metabolism, atherosclerosis formation, plasma glucose levels, and maintenance of gastric mucosa integrity. In addition to the regulation of nutrient metabolism, the emerging role of GLPs and their degrading enzyme dipeptidyl peptidase-4 (DPP-4) in gastrointestinal diseases has gained increasing attention. Therefore, here we review the function of the DPP-4/GLP axis in IBD.

Differential intestinal anti-inflammatory effects of Lactobacillus fermentum and Lactobacillus salivarius in DSS mouse colitis: impact on microRNAs expression and microbiota composition. Mol Nutr Food Res 2017; 61.

Abstract
SCOPE To compare the intestinal anti-inflammatory effects of two probiotics Lactobacillus fermentum and Lactobacillus salivarius in mouse colitis, focusing on their impact on selected miRNAs and microbiota composition. METHODS AND RESULTS Male C57BL/6J mice were randomly assigned to four groups (n = 10): non-colitic, DSS colitic and two colitic groups treated with probiotics (5 × 108 CFU/mouse/day). Both probiotics ameliorated macroscopic colonic damage. They improved the colonic expression of markers involved in the immune response, and the expression of miR-155 and miR-223. L. fermentum also restored miR-150 and miR-143 expression, also linked to the preservation of the intestinal barrier function. Besides, these beneficial effects were associated with the amelioration of the microbiota dysbiosis and a recovery of the SCFAs- and lactic acid-producing bacterial populations, although only L. fermentum improved Chao richness, Pielou evenness and Shannon diversity. Moreover, L. fermentum also restored the Treg cell population in MLNs and the Th1/Th2 cytokine balance. CONCLUSION Both probiotics exerted intestinal anti-inflammatory effects in DSS-mouse colitis, maybe due to their ability to restore the intestinal microbiota homeostasis and modulate the immune response. L. fermentum showed a greater beneficial effect compared to L. salivarius, which makes it more interesting for future studies.

Abstract
INTRODUCTION Methionine cycle plays an essential role in regulating many cellular events, especially transmethylation reactions, incorporating the methyl donor S-adenosylmethionine (SAM). The transmethylations and substances involved in the cycle have shown complicated effects and mechanisms on immunocytes developments and activations, and exert crucial impacts on the pathological processes in immune disorders. Areas covered: Methionine cycle has been considered as an effective means of drug developments. This review discussed the role of methionine cycle in immune responses and summarized the potential therapeutic strategies based on the cycle, including SAM analogs, methyltransferase inhibitors, S-adenosylhomocysteine hydrolase (SAHH) inhibitors, adenosine receptors specific agonists or antagonists and homocysteine (Hcy)-lowering reagents, in treating human immunodeficiency virus (HIV) infections, systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), multiple sclerosis (MS), systemic sclerosis (SSc) and other immune disorders. Expert opinion: New targets and biomarkers grown out of methionine cycle have developed rapidly in the past decades. However, impacts of epigenetic regulations on immune disorders are unclear and whether the substances in methionine cycle can be clarified as biomarkers remains controversial. Therefore, further elucidation on the role of epigenetic regulations and substances in methionine cycle may contribute to exploring the cycle-derived biomarkers and drugs in immune disorders.

Abstract
Inflammatory bowel diseases (IBDs), including Crohn's disease (CD) and ulcerative colitis (UC), are prevalent and debilitating health problems worldwide. Many types of drugs are used to treat IBDs, but they exhibit adverse effects such as vomiting, nausea, abdominal pain, diarrhea, etc. In order to overcome the limitations of current therapeutic drugs, scientists have searched for functional foods from natural resources. In this study, we investigated the anti-colitic effects of Wasabia japonica extract in a DSS-induced colitis model. Wasabi japonica is a plant of the Brassicaceae family that has recently been reported to exhibit properties of detoxification, anti-inflammation, and induction of apoptosis in cancer cells. In this study, we generated wasabi ethanol extract (WK) and assessed its anti-colitic effect. In addition, in order to improve delivery of the extract to the colon, WK was coated with 5% Eudragit S100 (WKE), after which the anti-colitic effects of WKE were assessed. In conclusion, WK prevented development of colitis through inhibition of the NF-kB signaling pathway and recovery of epithelial tight junctions. In addition, the anti-colitic effect of WK was enhanced by improving its delivery to the colon by coating the WK with Eudragit S100. Therefore, we suggest that wasabi can be used as a new functional food to prevent IBDs due to its anti-colitic effect.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) of the colon as a target site. Previous reports regarding the efficacy of α-mangostin (αMG) to inhibit nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinases (MAPKs) as well as relatively high distribution to the colon suggested the therapeutic potential of this compound in UC model. In dextran sodium sulfate (DSS)-induced colitis mice (DSS mice), the disease activity index scores involving diarrhea, bloody stool, body weight reduction, and myeloperoxidase (MPO) activities of the esophagus and colon increased with the reduced colon length. Also histologic disturbances and changes of NF-κB and MAPK pathways including phosphorylation of IκB kinase, ERK1/2, SAPK/JNK and p38 were observed in the colon of the DSS mice. However, all of these impaired conditions in the DSS mice were restored by αMG treatment, and the intestinal metabolism of αMG decreased, increasing its distribution to the colons in the DSS mice compared with the control mice. All of these results suggest that high distribution of αMG in the colon might attenuate DSS-induced colitis by inhibiting NF-κB and MAPK pathways in the colon.

Predicting Pre-emptive Discussions of Biologic Treatment: Results from an Openness and Preference Survey of Inflammatory Bowel Disease Patients and Their Prescribers. Adv Ther 2017; 34:1398-1410. [PMID: 28484953 PMCID: PMC5487867 DOI: 10.1007/s12325-017-0545-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Indexed: 12/21/2022]
Abstract
INTRODUCTION It is important to compare patient and provider discrepancies on stated openness to and preference for biologics as well as predictors associated with initial discussions on biologic use. METHODS Patients (N = 263) and physicians (N = 100) completed a self-administered Web-based survey assessing demographics, health characteristics, and behaviors related to inflammatory bowel disease (IBD) treatment. Bootstrap methods were used to check discrepancies between providers' and patients' stated openness to and preference for biologics. Classification and regression tree (CART) analysis identified patient-specific predictors associated with initial biologics discussions. RESULTS A total of 170 patients responded consistently to preference questions, and 169 patients responded consistently to openness questions. Physicians significantly overestimated patients' openness to biologics in general (85.46% vs. 74.61%, p < 0.0001), but underestimated patients' openness to the intravenous (IV) mode of administration (MOA; 55.97% vs. 63.96%, p < 0.0001). Overall, physicians significantly underestimated patient preference for IV MOA (22.07% vs. 42.35%, p < 0.0001) and, to a lesser extent, subcutaneous MOA (48.84% vs. 54.69%, p < 0.0001). Among Crohn's disease (CD) patients (N = 123), CART threshold analysis identified an inpatient visit in the last 6 months, CD diagnosis for more than 3 years, and non-adherence to prior IBD treatment as most positively predictive of having an initial biologics discussion. CONCLUSION Physicians appear to underestimate patient preferences in favor of biologics, especially IV formulations. Since it is unclear if physicians were aware of the patients' preferences beforehand, this study supports the need for validated, shared decision-making tools when initiating IBD treatment. Additional studies are necessary to measure physicians' influences on patient preference/treatment-related decisions and the impact on patient outcomes.

Abstract
Background There is no established treatment of AA amyloidosis, a long-term complication of various chronic inflammatory diseases associated with increased mortality, such as familial Mediterranian fever (FMF). Recently there are few reports pointing out that tocilizumab(TCZ), an anti IL-6 agent may be effective in AA amyloidosis resistant to conventional treatments. We report our data on the effect of TCZ in patients with FMF complicated with AA amyloidosis. Methods FMF patients with histologically proven AA amyloidosis, treated with TCZ (8 mg/kg per month) were followed monthly and the changes in creatinine, creatinine clearance, the amount of 24-hour urinary protein, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were noted throughout the treatment period. Adverse effects of the treatment were closely monitored. Results TCZ was given to 12 patients (6 F, 6 M) who also continued to receive colchicine (1.9 ± 0.4 mg/day). Coexisting diseases were ankylosing spondylitis(4) and Crohn’s disease(1). The mean age was 35.2 ± 10.0 years and the mean follow-up on TCZ was 17.5 ± 14.7 months. The renal functions remained stable (mean creatinine from 1.1 ± 0.9 mg/dl to 1.0 ± 0.6 mg/dl), while a significant decrease in acute phase response (the mean CRP from 18.1 ± 19.5 mg/L to 5.8 ± 7.1 mg/L and ESR from 48.7 ± 31.0 mm/h to 28.7 ± 28.3 mm/h) was observed and the mean 24-hour urinary protein excretion reduced from 6537.6 ± 6526.0 mg/dl to 4745.5 ± 5462.7 mg/dl. Two patients whose renal functions were impaired prior to TCZ therapy improved significantly on this regimen. No infusion reaction was observed. None of the patients experienced any FMF attack under TCZ treatment with the exception of 2, one of whom had less frequent attacks while the other had episodes of erysipelas-like erythema. Conclusıon Tocilizumab improved the acute phase response and the renal function in this group of patients and was generally well tolerated. Besides improving the renal function TCZ seemed to control the recurrence of FMF attacks too. Further studies are warrented to test the efficacy and safety of TCZ in AA amyloidosis secondary to FMF as well as other inflammatory conditions.

Abstract
Cytokines play an important role in the immunopathogenesis of inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, where they drive and regulate multiple aspects of intestinal inflammation. The imbalance between proinflammatory and anti-inflammatory cytokines that occurs in IBD results in disease progression and tissue damage and limits the resolution of inflammation. Targeting cytokines have been novel strategies in the treatment of IBD. Recent studies show the beneficial effects of anticytokine treatments to IBD patients, and multiple novel cytokines are found to be involved in the pathogenesis of IBD. In this review, we will discuss the recent advances of novel biologics in clinics and clinical trials, and novel proinflammatory and anti-inflammatory cytokines found in IBD with focusing on IL-12 family and IL-1 family members as well as their relevance to the potential therapy of IBD.

Abstract
Ulcerative colitis (UC) is a chronic, relapsing and debilitating idiopathic inflammation, with variable and complex pathophysiologies. Our objective was to elucidate patterns of gene expression underlying the progression of UC disease. Single endoscopic pinch FFPE biopsies (n = 41) were sampled at both active and inactive stages at the same site in individual UC patients and compared with each other and with non-inflammatory bowel disease healthy controls. Gene expression results were validated by quantitative reverse transcriptase-PCR (QRT-PCR), and results at the protein level were validated by immunohistochemistry and western blot. Analysis of microarray results demonstrated that UC patients in remission display an intermediate gene expression phenotype between active UC patients and controls. It is clear that UC active site recovery does not revert fully back to a healthy control phenotype. Both UC active and inactive tissue displayed evidence, at both the gene expression and protein level, of a positive precancerous state as indicated by increases in the expression of Chitinase 3-Like-1, and the colorectal cancer metastasis marker MMP1. A key distinguishing feature between active and inactive UC, however, was the mobilization of marker genes and proteins for the Epithelial Mesenchymal Transition (EMT) pathway only in active UC. Analysis of the gene expression signatures associated with UC remission identified multiple pathways which appear to be permanently dysregulated in UC patients at formerly active sites in spite of clear histological recovery. Among these pathways, the EMT pathway was specifically up-regulated only in active UC emphasizing the potential for cancer progression in these patients.

Abstract
OBJECTIVE Emerging evidence suggests that microRNA (miRNA)-mediated gene regulation influences a variety of autoimmune disease processes, including Crohn's disease (CD), but the biological function of miRNAs in CD remains unclear. We examine miRNA level in colon tissues and study the potential functions of miRNAs that regulate pathological genes during the inflammation process. DESIGN miRNA levels were assayed in the inflamed colon of 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced and IL-10 knockout (KO) chronic colitis mice and CD patients by microarray or qRT-PCR. The influence of differently expressed miR-141 on its putative target genes, CXCL12β, and leukocyte migration was investigated in colonic epithelia cells, colitis models and CD patients. The role of miR-141 was further studied in the experimental colitis mice by intracolonic administration of miR-141 precursors or inhibitors. RESULTS An inverse correlation between miR-141 and CXCL12β/total-CXCL12 was observed predominantly in the epithelial cells of the inflamed colons from colitic mice and CD patients. Further study demonstrated that miR-141 directly regulated CXCL12β expression and CXCL12β-mediated leukocyte migration. Upregulation or downregulation of miR-141 in the TNBS-induced or IL-10 KO colitic colon regulated leukocyte infiltration and alleviated or aggravated experimental colitis, respectively. Additionally, colonic overexpression of CXCL12β abolished the therapeutic effect of miR-141 in TNBS-induced colitis. CONCLUSIONS This study showed that the pathway of miR-141 targeting CXCL12β is a possible mechanism underlying inflammatory cell trafficking during colonic inflammation process. Inhibiting colonic CXCL12β expression and blocking colonic immune cell recruitment by using miRNA precursors represents a promising approach that may be valuable for CD treatment.

Abstract
BACKGROUND Overexpression of IL-23 has been implicated in the pathogenesis of Crohn's disease. Using vaccines to block overexpressed endogenous cytokines has emerged as a new therapeutic strategy for the long-term treatment of the disease. AIM We sought to develop peptide-based vaccines specific to IL-23 and evaluate their effects in colitis mice. MATERIALS & METHODS The vaccine was developed by inserting a peptide derived from mouse IL-23 p19 into the carrier protein, hepatitis B core antigen, using molecular engineering methods. One vaccine against IL-23 p19 was obtained that induced high-titered and long-lasting antibodies to IL-23 without the use of adjuvants. The inhibitory effect of vaccine-immunized serum was subsequently evaluated in vitro. To evaluate the in vivo effects, mice were subcutaneously injected with the vaccine, carrier or saline three times. Two weeks after the last injection, chronic colitis was induced in mice by seven weekly administrations with 2,4,6-trinitrobenzene sulfonic acid. RESULTS In vitro studies revealed that serum IL-23 p19-specific IgG significantly suppressed IL-23-induced IL-17 production by splenocytes. In vivo evaluation of the effect of the vaccine in mice with chronic colitis indicated that vaccine-immunized mice exhibited a decrease in colon inflammation, collagen deposition and levels of IL-23 and IL-12 cytokines, compared with control groups. CONCLUSION IL-23 p19 vaccine is capable of downregulating inflammatory responses in chronic murine colitis, providing a novel therapeutic approach in Crohn's disease.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE AND AIM OF THE STUDY Phellinus linteus is a herb used in traditional Asian medicine to treat stomachache, inflammation, and tumors. Recent studies show that the extract of Phellinus linteus has anti-inflammatory and antitumor activities. However, Phellinus linteus extract has limitation of high cost and limited availability because of supply shortage. Here, we grew Phellinus linteus on germinated brown rice to address the issue of supply shortage and investigated anti-inflammatory effect in vivo as well as in vitro. MATERIALS AND METHODS Phellinus linteus grown on germinated brown rice (PBR) were extracted using filtration steps, which included γ-aminobutyric acid (GABA). The PBR (200, 500mg/kg/day) was applied into the mouse model of dextran sodium sulfate (DSS)-induced colitis and lipopolysaccharide (LPS)-stimulated mouse macrophage RAW264.7 cells. We used sulfasalazine as a reference drug. In addition, mechanism related to anti-inflammatory was investigated by Western blotting. RESULTS In the mouse model of DSS-induced colitis, PBR ameliorated the pathological characteristics of colitis such as shortening of colon length and improved the disease activity index score. In addition, we showed that PBR reduced the expression of nuclear factor-kappa B (NF-κB) in colitis. Western blotting showed that PBR decreased the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (Cox-2) proteins. Further, PBR treatment reduced the expression of mitogen-activated protein kinases (MAPKs) (e.g., extracellular signal-regulated protein kinase (ERK) and p38) in the mouse model of DSS-induced colitis. CONCLUSIONS Treatment of RAW 264.7 macrophages with a combination of PBR and LPS showed a significant concentration-dependent inhibition of nitric oxide (NO) and prostaglandin E2 (PGE2) production. In addition, we determined the ability of PBR to reduce the iNOS and tumor necrosis factor (TNF)-α expression. PBR inhibited the expression of iNOS, NF-κB, and Cox-2 proteins in LPS-stimulated RAW264.7 macrophages. This study presents the potential use of PBR as a drug candidate against colitis.

Abstract
Inflammation is an immune response that marks several pathophysiological conditions in our body. Though adaptive immune cells play a major role in the progression of the disease, components of innate immune system, mainly monocytes and macrophages play the central role in onset of inflammation. Tissue-associated macrophages are widely distributed in the body showing tremendous anatomical and functional diversity and are actively involved in maintaining the homeostasis. They exhibit different phenotypes depending on their residing tissue microenvironment and the two major functional phenotypes are classically activated M1 phenotype showing pro-inflammatory characteristics and alternatively activated M2 phenotype demonstrating anti-inflammatory nature. Several cytokines, chemokines and other regulatory mediators delicately govern the balance of the two phenotypes in a tissue. This balance, however, is subverted during infection, injury or autoimmune response leading to increased population of M1 phenotype and subsequent chronic inflammatory disease states. This review underlines the role of macrophages in inflammatory diseases with an insight into potential molecular targets for nucleic acid therapy. Finally, some recent nanotechnology-based approaches to devise macrophage-specific targeted therapy have been highlighted.

Abstract
Intestinal crypt epithelial cells synthesize glucocorticoids, steroid hormones that protect against inflammatory bowel disease. To investigate how intestinal glucocorticoids are regulated during chronic inflammation, we induced chronic colitis in mice by exposing them to the chemical dextran sulfate sodium (DSS). We found that intestinal glucocorticoid secretion and expression of the genes Cyp11a1 and Cyp11b1 (which encode enzymes that synthesize glucocorticoids) were initially stimulated, but declined during the chronic phase, whereas tumor necrosis factor (TNF) and inflammatory cytokines secreted by T helper type 1 (TH1) and TH17 cells continuously increased in abundance in the inflamed colon. This suggested that inadequate intestinal glucocorticoid synthesis is a feature of chronic intestinal inflammation. We screened for cytokines that regulated intestinal glucocorticoid synthesis and found that TNF suppressed corticosterone secretion and Cyp11a1 and Cyp11b1 expression in an intestinal crypt epithelial cell line. TNF suppressed steroidogenesis by activating the transcription factors c-Jun and nuclear factor κB (NF-κB), which both interacted with the transcription factor NR5A2 and repressed Cyp11a1 reporter activity. This repression was relieved by expression of a dominant-negative form of c-Jun amino-terminal kinase 1 (JNK1), inhibitor of NF-κB, or by a JNK inhibitor. Furthermore, the dominant-negative TNF inhibitor XPro1595 inhibited c-Jun and NF-κB activation in mice, restored intestinal Cyp11a1 and Cyp11b1 expression, reduced colonic cell death, and rescued chronic colitis caused by DSS. Thus, during chronic colitis, TNF suppresses intestinal steroidogenic gene expression by inhibiting the activity of NR5A2, thus decreasing glucocorticoid synthesis and sustaining chronic inflammation.

Abstract
The metabolic syndrome can be prevented by the Mediterranean diet, characterized by fiber, omega-3 polyunsaturated fatty acids and polyphenols. However, the composition of the Mediterranean diet, which can be viewed as a natural multiple supplement, is poorly controlled, and its beneficial effects poorly predictable. The metabolic syndrome is associated with intestinal dysbiosis and the gut microbioma seems to be the main target and player in the interactions occurring between probiotics, prebiotics, omega 3 polyunsaturated fatty acids, and polyphenols. From the reviewed evidence, it is reasonable to manage growth and metabolism of gut microflora with specific prebiotics and polyphenols. Even though the healthy properties of functional foods and nutraceuticals still need to be fully elucidated, available data suggest that well-designed supplements, containing the better ratio of omega-3 polyunsaturated fatty acids and antioxidants, specific probiotic strains, and selected polyphenols and prebiotics, could be useful in metabolic syndrome prevention and treatment.

Abstract
The nociceptin receptors (NOPs) are expressed in the gastrointestinal (GI) tract on muscle cell membranes and neurons, as well as the immune cells that infiltrate the mucosa. The involvement of NOPs in the pathophysiology of GI inflammation has been suggested, but due to the lack of selective NOP agonists, it never fully elucidated. Our aim was to characterize the anti-inflammatory and antinociceptive effect of the NOP agonist, SCH 221510 [3-endo-8-[bis(2-methylphenyl)methyl]-3-phenyl-8-azabicyclo [3.2.1]octan-3-ol], as a potential therapeutic strategy in the treatment of inflammatory bowel diseases (IBD). The anti-inflammatory action of SCH 221510 was determined after intraperitoneal, oral, and intracolonic administration of SCH 221510 (0.1-3.0 mg/kg once or twice daily) in mice treated with 2,4,6-trinitrobenzenesulfonic acid (TNBS). Antinociceptive action of SCH 221510 was evaluated in the mouse model of mustard oil (MO)-induced abdominal pain. Relative NOP mRNA expression was assessed in patients with IBD using real-time reverse transcriptase-polymerase chain reaction. We found that the expression of NOP mRNA was significantly decreased in patients with IBD. The administration (0.1 and 1.0 mg/kg i.p. twice daily and 3 mg/kg p.o. twice daily) of SCH 221510 attenuated TNBS colitis in mice. This effect was blocked by a selective NOP antagonist [J-113397 [(±)-1-[(3R*,4R*)-1-(cyclooctylmethyl)-3-(hydroxymethyl)-4-piperidinyl]-3-ethyl-1,3-dihydro-2H-benzimidazol-2-one]]. The intracolonic injections of SCH 221510 did not improve colitis in mice. The antinociceptive effect of SCH 221510 was observed after oral administration of SCH 221510 in MO-induced pain tests in mice with acute colitis. In conclusion, our results show a potent anti-inflammatory and antinociceptive effect upon selective activation of NOP receptors and suggest that the NOP agonist SCH 221510 is a promising drug candidate for future treatment of IBD.
