Abstract
Inflammatory bowel disease (IBD) is a chronic disease that affects the entire digestive tract. IBD can be classified as ulcerative colitis or Crohn's disease. The key symptoms of IBD include the emergence of abscesses or pustules, pronounced abdominal discomfort, diarrhea, fistulas, and intestinal narrowing, all of which can greatly affect a patient's daily well-being. Several factors, including bacterial infections, immune response irregularities, and changes in the intestinal milieu, can contribute to the onset of IBD. The aim of this study was investigating the role of cirsimaritin in reducing the severity of colitis in animal model. To induce colitis in laboratory Swiss albino mice, a 4% dextran sulfate sodium (DSS) concoction was provided in their hydration source for a duration of six days. Before the onset of colitis, mice were treated with cirsimaritin (10 mg/kg) once daily to evaluate its potential treatment effects against DSS-induced inflammation. The results showed that 10 mg/kg of cirsimaritin decreased colitis severity (P<0.05). Moreover, cirsimaritin successfully reversed the detrimental effects induced by DSS, including weight reduction, colon truncation, tissue-related damage, increased levels of inflammatory cells in the affected region, and secretion of proinflammatory cytokines. Our findings suggest that cirsimaritin can effectively alleviate acute colitis triggered by DSS.

Abstract
Inflammatory bowel disease (IBD) is a collective term for two diseases: ulcerative colitis (UC) and Crohn's disease (CD). There are many factors, e.g., genetic, environmental and immunological, that increase the likelihood of these diseases. Indicators of IBDs include extracellular matrix metalloproteinases (MMPs). The aim of this review is to present data on the role of selected cytokines and metalloproteinases in IBD. In recent years, more and more transcriptomic studies are emerging. These studies are improving the characterization of the cytokine microenvironment inside inflamed tissue. It is observed that the levels of several cytokines are consistently increased in inflamed tissue in IBD, both in UC and CD. This review shows that MMPs play a major role in the pathology of inflammatory processes, cancer, and IBD. IBD-associated inflammation is associated with increased expression of MMPs and reduced ability of tissue inhibitors of metalloproteinases (TIMPs) to inhibit their action. In IBD patients in tissues that are inflamed, MMPs are produced in excess and TIMP activity is not sufficient to block MMPs. This review is based on our personal selection of the literature that was retrieved by a selective search in PubMed using the terms "Inflammatory bowel disease" and "pathogenesis of Inflammatory bowel diseases" that includes systematic reviews, meta-analyses, and clinical trials. The involvement of the immune system in the pathophysiology of IBD is reviewed in terms of the role of the cytokines and metalloproteinases involved.

Abstract
Background The ulcerative colitis (UC) and Crohn's disease (CD) subtypes of inflammatory bowel disease (IBD) are autoimmune diseases influenced by multiple complex factors. The clinical treatment strategies for UC and CD often differ, indicating the importance of improving their discrimination. Methods Two methods, robust rank aggregation (RRA) analysis and merging and intersection, were applied to integrate data from multiple IBD cohorts, and the identified differentially expressed genes (DEGs) were used to establish a protein-protein interaction (PPI) network. Molecular complex detection (MCODE) was used to identify important gene sets. Two differential diagnostic models to distinguish CD and UC were established via a least absolute shrinkage and selection operator (LASSO) logistic regression, and model evaluation was performed in both the training and testing groups, including receiver operating characteristic (ROC) curves, calibration plots and decision curve analysis (DCA). The potential value of MMP-associated genes was further verified using different IBD cohorts and clinical samples. Results Four datasets (GSE75214, GSE10616, GSE36807, and GSE9686) were included in the analysis. Both data integration methods indicated that the activation of the MMP-associated module was significantly elevated in UC. Two LASSO models based on continuous variable (Model_1) and binary variable (Model_2) MMP-associated genes were established to discriminate CD and UC. The results showed that Model_1 exhibited good discrimination in the training and testing groups. The calibration analysis and DCA showed that Model_1 exhibited good performance in the training group but failed in the testing group. Model_2 exhibited good discrimination, calibration and DCA results in the training and testing groups and exhibited greater diagnostic value. The effects of Model_1 and Model_2 were further verified in a new IBD cohort of GSE179285. The MMP genes exhibited high value as biomarkers for the discrimination of IBD patients using published cohort and immunohistochemistry (IHC) staining data. The MMP-associated gene levels were statistically significantly positively correlated with the levels of the differentially expressed cell types, indicating their potential value in differential diagnosis. The single-cell analysis confirmed that the expression of ANXA1 in UC was higher than that in CD. Conclusion MMP-associated modules are the main differential gene sets between CD and UC. The established Model_2 overcomes batch differences and has good clinical applicability. Subsequent in-depth research investigating how MMPs are involved in the development of different IBD subtypes is necessary.

Abstract
The aim of the present study was to explore the effects of bone marrow mesenchymal stem cells (BMSCs), combined with Atractylodes macrocephala polysaccharide (AMP), in an experimental model of ulcerative colitis. BMSCs were first isolated, cultured, and identified by flow cytometry. A rat model of colitis was established by trinitrobenzene sulfonic acid (TNBS) injection. Rats were treated with BMSCs with or without AMP for 1 or 2 weeks. H&E staining was performed to assess the extent of histological injury. IEC-6 and BMSCs were co-cultured and treated with AMP. Cell migration was measured using the Transwell assay, whilst the levels of cytokines in the rat blood samples were detected using ELISA. In addition, cytokine levels in the cell supernatant were measured by microarray. The results showed that BMSCs were successfully isolated. BMSCs treatment could markedly alleviate injury according to histological analysis and regulate inflammatory cytokine production in this rat model of TNBS-induced colitis, where a higher number of BMSCs was found in the intestinal tract, compared to the model. AMP not only potentiated the effects of BMSCs on preventing TNBS-induced colitis but also promoted BMSC homing to the injured tissue and regulated cytokines. Furthermore, BMSCs and AMP promoted the migration of IEC in vitro and influenced multiple genes. In conclusion, AMP treatment improved the therapeutic effects of BMSCs on ulcerative colitis, potentially providing a novel clinical treatment strategy for colitis.

Abstract
Inflammatory bowel diseases (IBD) are chronic inflammatory diseases of the gastrointestinal tract, encompassing two main disorders: Crohn's disease (CD) and ulcerative colitis (UC). In both these pathologies, excessive and local immune response against luminal antigens promotes a pathological process leading to various degrees of gut damage. Matrix metalloproteinases (MMPs) are a family of neutral proteases with the ability to degrade all components of extracellular matrix. In physiological conditions, MMPs are produced at very low level and generally in the latent form and are involved in the normal tissue turnover. Their function is inhibited by tissue inhibitors of metalloproteinases (TIMPs). However, in inflamed tissue of IBD patients, MMPs are produced in excess and/or the activity of TIMPs is not sufficient to block MMPs, thereby making a major contribution to the IBD-related mucosal degradation. In this review, we summarize the available evidence on the expression and role of MMPs in IBD.

Abstract
AbstractThe inflammatory disease’s increased prevalence leads to a major concern around the world. Still, there is a lack of effective and successful therapy in the reversal of Inflammatory Bowel Disease (IBD) symptoms. Whereas, reactive oxygen species (ROS) production and muddled defense capacity of antioxidants in IBD subjects reported several times. Many proton pump inhibitors have been reported previously for their anti-inflammatory effect. The present study is aimed to assess the ameliorative effect of lansoprazole in experimentally induced IBD in rats. Thirty-six female Sprague Dawley rats were divided equally into six groups based on their body weight. Lansoprazole (1, 5, and 10 mg/kg, p.o.) and 5-aminosalicylate (5-ASA, 100 mg/kg, p.o.) served as standard control respectively, given for 18 days once a day. On the 11th day of the study, colitis was induced by intrarectal instillation of 2, 4-Dinitrobenzene sulfonic acid (DNBS), and treatment was continued for the next 7 days. Administration of lansoprazole (at 5 and 10 mg/kg) significantly reduced DAI (Disease Activation Index) and CMDI (Colon Macroscopic Damage Index); which further justifies a reduction in colon inflammation grades, as well as histopathological changes, and reflected by the stalling of body weight. The anti-inflammatory effects were indicated by lowered MPO (myeloperoxidase) and SOD (superoxide dismutase) in colon tissue as well as restores colonic NO (nitric oxide) level. The study shows lansoprazole improved DAI and CMDI scores, reduction of neutrophil infiltration, and an improved antioxidant status indicating an anti-ulcerative effect in DNBS-induced experimental colitis that is comparable with 5-ASA treatment.

Abstract
Inflammatory bowel disease (IBD) is a continual ailment condition which engrosses the entire alimentary canal. The IBD can be primarily distinguished into two forms, ulcerative colitis, and Crohn's disease. The major symptoms of IBD include pustules or abscesses, severe abdominal pain, diarrhea, fistula, and stenosis, which may directly affect the patient's quality of life. A variety of mediators can stimulate the circumstances of IBD, some examples include infections by microbes such as bacteria, perturbation of the immune system and the surrounding environment of the intestines. Severe colitis was stimulated in the experimental animals through administering 4% dextran sulfate sodium (DSS) which is mixed in water ad libitum for 6 days. Eriocitrin (30 mg/kg) was then administered to the experimental animals followed by the induction of severe colitis to evaluate the therapeutic prospective of eriocitrin against the colon inflammation stimulated by DSS. In this study, eriocitrin (30 mg/kg) demonstrated significant (P < .05) attenuation activity against the DSS-stimulated severe colitis in experimental animals. Eriocitrin counteracted all of the clinical deleterious effects induced by DSS, such as body-weight loss, colon shortening, histopathological injury, accretion of infiltrated inflammatory cells at the inflamed region and the secretion of inflammatory cytokines. The results clearly showed that eriocitrin effectively attenuated DSS-induced acute colitis in experimental animals.

Abstract
The aim of this study was to investigate the effects of a sulfasalazine-containing hyaluronic acid (SASP/HA) systems on in vitro anti-inflammation and the alleviation of cartilage degradation in both lipopolysaccharide (LPS)-stimulated synoviocytes and a rat model of monosodium iodoacetate (MIA)-induced osteoarthritis (OA). The SASP/HA resulted in long-term release of SASP from the SASP/HA for up to 60 days in a sustained manner. In vitro studies performed using real-time polymerase chain reaction (PCR) assay revealed that the SASP/HA was able to effectively and dose-dependently inhibit the mRNA expression levels of pro-inflammatory cytokines such as matrix metalloproteinases-3 (MMP-3), cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in LPS-stimulated synoviocytes. In vivo studies showed that intra articular injection of SASP/HA greatly reduced the MIA-stimulated mRNA expression of MMP-3, COX-2, IL-6, and TNF-α in blood. Furthermore, these significant anti-inflammatory effects of SASP/HA contributed markedly to the alleviation of progression of MIA-induced OA and cartilage degradation, as demonstrated by X-ray, micro-computed tomography (micro-CT), gross findings, and histological evaluations. Therefore, our findings indicated that the long-term and sustained delivery of SASP using HA can play a therapeutic role in alleviating inflammation as well as protecting against cartilage damage in OA.

Abstract
AIM To investigate the therapeutic and immunoregulatory effects of 1,25-dihydroxyvitamin D (1,25(OH)D3) on 2,4,6-trinitrobenzenesulfonic acid (TNBS) -induced colitis in rats. METHODS Experimental colitis induced by enema administration of TNBS plus ethanol was treated with 5-aminosalicylic acid (5-ASA) and/or 1,25(OH)D3. Disease activity was measured using the disease activation index (DAI), colon macroscopic damage index (CMDI), histological colonic damage score, and myeloperoxidase (MPO) activity. The expression of toll-like receptor 9 (TLR9) in the colon was determined by reverse transcription-polymerase chain reaction and immunohistochemistry. RESULTS Rats with TNBS-induced colitis had significantly elevated DAI, CMDI, histological colonic damage score, and MPO activity (all P<0.001) compared to rats without colitis. Treatment with 5-ASA or 1,25(OH)D3 ameliorated colitis by lowering CMDI (P=0.049, P=0.040, respectively), histological colonic damage score (P=0.010, P=0.005, respectively), and MPO activity (P=0.0003, P=0.0013, respectively) compared with the TNBS group. Combined treatment with 5-ASA and 1,25(OH)D3 significantly decreased MPO activity (P=0.003). 1,25(OH)D3 attenuated colitis without causing hypercalcemia or renal insufficiency. TNBS significantly increased the number of TLR9 positive cells compared to control (P<0.010), while 5-ASA, 1,25(OH)D3, and combined treatment with 5-ASA and 1,25(OH)D3 significantly decreased it compared to TNBS group (all P<0.010). In TNBS group a moderate correlation was observed between MPO activity and the number of TLR9-positive cells (r=0.654, P<0.001). CONCLUSION TLR9 expression correlates with the extent of inflammation in TNBS-induced colitis. 1,25(OH)D3 relieves this inflammation possibly by decreasing TLR9 expression.

Abstract
OBJECTIVE To analyze the immunological characteristics of 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis model and examine the therapeutic effects and mechanisms of Astragalus polysaccharides (APS) treatment. METHODS Thirty-two male specific pathogen free Spragne-Dawley rats were randomly equally assigned to four groups: control, TNBS, APS and prednisone groups. Experimental colitis was induced by enema administration of TNBS. Then rats were treated with APS (0.5 g•kg-1•day-1, once daily) or prednisone (1.0 mg•kg-1•day-1, once daily) by gavage for 14 days. Macroscopic lesion and histological damage were determined, and activity of myeloperoxidase (MPO) was measured in the colonic tissues. Expressions of T-box expressed in T-cells (T-bet) and GATA-binding protein-3 (GATA-3) were determined by immunohistochemistry analysis and western blot. RESULTS Both macroscopic lesion and histological colonic damage induced by TNBS were reduced by APS and prednisone treatment. These were accompanied by significant attenuation of MPO activity (P=0.03). TNBS intervention enhanced the expression of both GATA-3 and T-bet, but the expression of T-bet was significantly enhanced than that of GATA-3, resulting in significant reduction of GATA-3/T-bet ratio (P=0.025). APS administration enhanced the expression of T-bet (P=0.04) and GATA-3 (P=0.019) in comparison to TNBS group, and resulting in an up-regulated GATA-3/T-bet ratio. Prednisone treatment inhibited both expressions; however it also resulted in up-regulation of the GATA-3/T-bet ratio. CONCLUSIONS These results demonstrated that APS exerted a beneficial immune regulatory effect on experimental colitis. It promoted the expression of T helper cell 1 (Th1) and T helper cell 2 (Th2) specific transcription factors but ultimately favor a shift toward Th2 phenotype, suggesting that APS possessed therapeutic potential in experimental colitis.

Abstract
Matrix metalloproteinase- (MMP-) 9 is one of the main metalloproteinases reported to be involved in extracellular matrix degradation and recently also in triggering of angiogenic switch in the course of inflammatory bowel diseases (IBD). The goal of our studies was to estimate in one experimental setting the levels of MMP-9 in sera of Crohn's Disease (CD) and ulcerative colitis (UC) patients and to evaluate its possible diagnostic potential in comparison with other biochemical markers and selected proinflammatory and angiogenic factors. The study group included 176 subjects (CD = 64, UC = 85, control = 27). Concentrations of serum MMP-9 were significantly higher in active than inactive forms of IBD, being higher in active UC than in active CD. Both in the case of CD and UC serum MMP-9 positively correlated with disease activity, IL-6 levels, platelet and leukocyte count, midkine, and PDGF-BB, as well as in UC with ESR and in CD with CRP, IL-1, and VEGF-A. Diagnostic accuracy of MMP-9 in distinguishing active UC from active CD was 66%, and displayed higher specificity than CRP (79.0% versus 61.6%, resp.). Evaluation of serum MMP-9 concentrations could aid in differentiation of active UC from active CD. MMP-9 correlated better with inflammatory and angiogenic parameters in CD than in UC.

Abstract
Inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) represent serious health burdens because of both the tissue-damaging disease itself and an elevated risk of colon cancer. The increased expression of many members of the matrix metalloproteinase (MMP) family of enzymes that occurs in colitis has long been associated with the destructive nature of the disease. Recent findings in cancer and other MMP-associated diseases, however, led us to question whether MMPs are indeed detrimental in the setting of colitis. Here, we focus on a single MMP family member, MMP10, and assess its role in a murine model of colonic tissue damage induced by dextran sulfate sodium (DSS) treatment. Using mice genetically deficient for MMP10, we find that absence of this enzyme leads to significantly worse disease scores and failure to resolve inflammation even after extended recovery periods. We show that MMP10 is produced predominantly by infiltrating myeloid cells in both murine and human colitis. Through bone marrow transplant experiments, we confirm that bone marrow-derived MMP10 contributes to colitis severity. Mice lacking MMP10 have a significantly higher propensity for development of dysplastic lesions in the colon after two rounds of DSS exposure. Thus, we conclude that MMP10 is required for resolution of DSS-induced colonic damage, and in its absence, chronic inflammation and ultimately dysplasia occurs.

Abstract
BACKGROUND Recently published data indicate that the inflammation in Crohn's disease (CD) may be accompanied by elevated levels of matrix metalloproteinases. AIMS The goals of the present study were the estimation of MMP-3 and -9 concentrations in sera of children with Crohn's disease, the examination of correlation between the concentrations of MMP-3 and -9 and clinical activity of the disease in the relation to the control group and the evaluation of the utility of MMP-3 and -9 concentration measurements as markers of disease activity. METHODS Serum concentrations of MMP-3 and -9 were estimated in 82 children (45 CD patients divided into severe, moderate and mild subgroups; 37 controls) and correlated with disease activity estimated by the Pediatric Crohn's Disease Activity Index (PCDAI), CRP, seromucoid and ESR. RESULTS Mean MMP-3 concentrations were: 2.49 ng/ml (95% CI: 1.76-3.52) for mild, 16.44 ng/ml (95% CI: 10.34-26.15) for moderate, 5.25 ng/ml (95% CI: 2.73-10.11) for severe CD and 1.95 ng/ml (95% CI: 1.53-2.48) for the control group (differences between all three groups were statistically significant; P < 0.001). Median MMP-9 concentrations were: 2.14 ng/ml (95% CI: 0-8.9) for mild, 14.21 ng/ml (95% CI: 4.53-21.48) for moderate, 42.2 ng/ml (95% CI: 5.74-61.27) for severe CD and 1.3 ng/ml (95% CI: 0.7-2.18) for the control group. MMP-9 concentrations in moderate and severe CD differed from the concentrations in mild CD (P = 0.002) and control group (P = 0.0001). MMP-3 concentration significantly correlated with MMP-9, PCDAI and ESR, while MMP-9 concentration significantly positively correlated with MMP-3, PCDAI, and CRP. Diagnostic utilities of the tests were: MMP-3 accuracy 75%, positive likelihood ratio (LR+) = 4.11 and negative likelihood ratio (LR-) = 0.51, sensitivity 56%, specificity 87%, Youden index 0.43; for MMP-9, accuracy 73%, LR+ = 5.14 and LR- = 0.50, sensitivity 56%, specificity 89%, Youden index 0.45; and for CRP, accuracy 74%, LR+ = 8.56 and LR- = 0.54, sensitivity 49%, specificity 94%, Youden index 0.43. CONCLUSIONS MMP-9 serum concentration increasing along with the activity of the disease, exhibiting high specificity and correlating well with the indices of inflammation might be of better usefulness in the prediction of CD activity status in children than MMP-3.

Abstract
In the experimental models of intestinal inflammation and humans with inflammatory bowel diseases (IBD), increased levels of the matrix metalloproteinases (MMPs), MMP-2 and -9 (also referred to as gelatinase A and B, respectively), in inflamed tissue sites can be detected. In the presented study, we investigated potential beneficial effects exerted by doxycycline nonselectively blocking MMPs and the selective gelatinase inhibitor RO28-2653 in acute DSS colitis. Treatment with either compound for 8 days ameliorated clinical colitis pathology with a superior outcome in RO28-2653-treated animals. As compared to placebo controls, histopathological changes in the colon were less distinct following MMP blockage and IL-6 secretion in ex vivo biopsies was downregulated, paralleled by a diminished influx of pro-inflammatory immune cells and lack of overgrowth of the colonic lumen by potentially pro-inflammatory Escherichia coli of the commensal colon flora. We conclude that selective gelatinase inhibition not only exerts beneficial effects by disrupting the vicious cycle of positive feedback between immune cell stimulation and MMP induction but also prevents overgrowth of the colonic lumen by pro-inflammatory E. coli despite a lack of direct anti-bacterial properties, thus unaffecting the commensal gut microbiota. These findings put RO28-2653 into a center stage for development of intervention strategies in human IBD.

Abstract
Methylsulfonylmethane (MSM), naturally occurring in green plants, fruits and vegetables, has been shown to exert anti-inflammatory and antioxidant effects. MSM is an organosulfur compound and a normal oxidative metabolite of dimethyl sulfoxide. This study was carried out to investigate the effect of MSM in a rat model of experimental colitis. Colitis was induced by intracolonic instillation of 1 ml of 5% of acetic acid. Rats were treated with MSM (400 mg/kg/day, orally) for 4 days. Animals were euthanized and distal colon evaluated histologically and biochemically. Tissue samples were used to measurement of malondialdehyde (MDA), myeloperoxidase (MPO), catalase (CAT), glutathione (GSH) and proinflammatory cytokine (TNF-α and IL-1β) levels. Results showed that MSM decreased macroscopic and microscopic colonic damage scores caused by administration of acetic acid. MSM treatment also significantly reduced colonic levels of MDA, MPO and IL-1β, while increased the levels of GSH and CAT compared with acetic acid-induced colitis group. It seems that MSM as a natural product may have a protective effect in an experimental ulcerative colitis.

Abstract
We examined the change of protein tyrosine kinases (PTKs) expression levels in colonic epithelial cells isolated from mice in which colitis was induced by oxazolone administration, using the monoclonal antibody YK34, which cross-reacts with a wide variety of PTKs. We identified focal adhesion kinase (FAK) and found the expression level increased due to the induction of colitis. Furthermore, we found that there was a positive correlation between FAK expression and the severity of colitis. Also, FAK expression localized in the colonic epithelium but not in the lamina propria, implying FAK functions in epithelial cells during colitis formation and/or wound repairing.

Abstract
BACKGROUND AND PURPOSE Cannabis is taken as self-medication by patients with inflammatory bowel disease for symptomatic relief. Cannabinoid receptor agonists decrease inflammation in animal models of colitis, but their effects on the disturbed motility is not known. (-)-Cannabidiol (CBD) has been shown to interact with Delta(9)-tetrahydrocannabinol (THC) in behavioural studies, but it remains to be established if these cannabinoids interact in vivo in inflammatory disorders. Therefore the effects of CBD and THC alone and in combination were investigated in a model of colitis. EXPERIMENTAL APPROACH The 2,4,6-trinitrobenzene sulphonic acid (TNBS) model of acute colitis in rats was used to assess damage, inflammation (myeloperoxidase activity) and in vitro colonic motility. Sulphasalazine was used as an active control drug. KEY RESULTS Sulphasalazine, THC and CBD proved beneficial in this model of colitis with the dose-response relationship for the phytocannabinoids showing a bell-shaped pattern on the majority of parameters (optimal THC and CBD dose, 10 mg.kg(-1)). THC was the most effective drug. The effects of these phytocannabinoids were additive, and CBD increased some effects of an ineffective THC dose to the level of an effective one. THC alone and in combination with CBD protected cholinergic nerves whereas sulphasalazine did not. CONCLUSIONS AND IMPLICATIONS In this model of colitis, THC and CBD not only reduced inflammation but also lowered the occurrence of functional disturbances. Moreover the combination of CBD and THC could be beneficial therapeutically, via additive or potentiating effects.

Abstract
A novel matrix metalloproteinase sequestering biomaterial (MI Theramer beads) restored the epithelial barrier in a double chamber in vitro test system after disruption by Cytochalasin D and the secretion of the metalloproteinase MMP-2. MI beads are chemically modified (hydroxamated) poly(methacrylic acid-co-methyl methacrylate). We are exploring the utility of this material in inflammatory bowel disease (IBD), in which one manifestation is a compromised intestinal epithelial barrier. In a first step towards this goal we incubated MI beads (or polymethyl methacrylate control beads) with Caco-2 epithelial cells and mesenchymal 3T3 fibroblasts on two sides of a Matrigel((R))-coated filter and used Cytochalasin D (Cyto D) to activate MMP-2 (secreted by the 3T3 cells), disrupt actin filaments of Caco-2 cells and render the epithelial barrier leaky, as measured by dextran fluorescein equilibration. Addition of MI beads to Cyto D-treated cells inhibited active MMP-2 and prevented equilibration of dextran fluorescein. This study is the first step in showing a potential benefit to local (as opposed to systemic) inhibition of metalloproteinases in IBD or other intestinal inflammatory diseases.

Abstract
The primary function of neutrophils in host defense is to contain and eradicate invading microbial pathogens. This is achieved through a series of swift and highly coordinated responses culminating in ingestion (phagocytosis) and killing of invading microbes. While these tasks are usually performed without injury to host tissues, in pathologic circumstances such as sepsis, potent antimicrobial compounds can be released extracellularly, inducing a spectrum of responses in host cells ranging from activation to injury and death. In the lung, such inflammatory damage is believed to contribute to the pathogenesis of diverse lung diseases, including acute lung injury and the acute respiratory distress syndrome, chronic obstructive lung disease, and cystic fibrosis. In these disorders, epithelial cells are targets of leukocyte-derived antimicrobial products, including proteinases and oxidants. Herein, we review the mechanisms involved in the physiologic process of neutrophil transepithelial migration, including the role of specific adhesion molecules on the leukocyte and epithelial cells. We examine the responses of the epithelial cells to the itinerant leukocytes and their cytotoxic products and the consequences of this for lung injury and repair. This paradigm has important clinical implications because of the potential for selective blockade of these pathways to prevent or attenuate lung injury.

Abstract
AIM To evaluate the protective effects of ilomastat, an exogenous matrix metalloproteinase (MMP) inhibitor, on trinitrobenzenesulfonic acid (TNB)-induced ulcerative colitis (UC) in rats. METHODS Male SD rats were randomly divided into model group, protective groups A and B, and normal control group. Rats in the model group received only intra-colonic TNB. Rats in the protective groups A and B received intra-peritoneal ilomastat of 10 mg/kg and 20 mg/kg, respectively, beside TNB. Rats in the normal control group received only intra-colonic normal saline. After 3 wk, segments of colon were obtained. RT-PCR and immunohistochemistry were used to examine the expression of MMP-1 and TIMP-1. Hematoxylin-eosin (HE) staining was used for pathological study. RESULTS The model of UC was successfully induced in rats. Inflammation of colonic mucosa greatly improved in protective groups A and B. Expression of MMP-1 and TIMP-1 in the model group, protective groups A and B was significantly higher than that in the normal control group (P < 0.0001) with MMP-1 expression increased more significantly than TIMP-1 expression. Expression of MMP-1 in protective groups A and B was significantly lower than that in the model group (P < 0.0001) . Expression of MMP-1 in protective group B was significantly lower than that in protective group A (P < 0.0001). CONCLUSION Ilomastat improves TNB-induced UC in rats by inhibiting the MMP-1 activity.

Abstract
BACKGROUND AND AIMS Tumor necrosis factor (TNF) superfamily members have attracted attention as new therapeutic targets for treating inflammatory disease. TNF-like weak inducer of apoptosis (TWEAK) is a unique, multifunctional TNF family cytokine that signals through its receptor, fibroblast growth factor-inducible molecule 14 (Fn14). The role of this pathway in the intestine has not been previously reported. METHODS The 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis model was conducted in TWEAK- or Fn14-deficient mice or in normal mice treated with a TWEAK-blocking monoclonal antibody, and clinical severity, histopathology, immunohistochemistry for cell infiltrates, TWEAK and Fn14, gene expression profiling in the colon, and systemic adaptive immunity were assessed. The effect of TWEAK on colon epithelial cell production of inflammatory mediators was analyzed in vitro. The gamma-irradiation injury model was conducted in TWEAK- or Fn14-deficient mice, and crypt epithelial death was assessed. RESULTS Colitis severity and histologic scores were significantly reduced by TWEAK pathway deficiency or TWEAK-blocking monoclonal antibody. Neutrophil and macrophage infiltrates, chemokines, cytokines, and matrix metalloproteinase expression were reduced in the TWEAK-deficient colon after TNBS administration; however, systemic adaptive immune responses to trinitrophenyl were not altered. Fn14 is expressed on colon epithelial cells in TNBS colitis, and TWEAK induces epithelial production of pathogenic mediators. TWEAK also regulates intestinal epithelial turnover, as evidenced by reduced epithelial cell death after gamma-irradiation injury in TWEAK and Fn14 knockout mice. CONCLUSIONS Our studies elucidate a nonredundant TWEAK-intestinal epithelial cell axis and suggest that blocking TWEAK may dampen chronic intestinal inflammation and allow normal epithelial repair.

Abstract
Matrix metalloproteinases (MMP) play an important role in pathogenesis of inflammatory bowel disease (IBD). Two known gelatinases, MMP-2 and MMP-9, are upregulated during IBD. Epithelial-derived MMP-9 is an important mediator of tissue injury in colitis, whereas MMP-2 protects against tissue damage and maintains gut barrier function. It has been suggested that developing strategies to block MMP-9 activity in the gut might be of benefit to IBD. However, given that MMP-2 and MMP-9 are structurally similar, such approaches would also likely inhibit MMP-2. Thus, to gain insight into outcome of inhibiting both MMP-2 and MMP-9, MMP-2(-/-)/MMP-9(-/-) double knockout mice (dKO) lacking both MMP-2 and MMP-9 were used in this study. Three models of murine colitis were used: dextran sodium sulfate (DSS), Salmonella typhimurium (S.T.), and trinitrobenzene sulfonic acid (TNBS). Our data demonstrate that MMP-2 and MMP-9 activities were highly upregulated in wild-type (WT) mice treated with DSS, S.T., or TNBS whereas dKO mice were resistant to the development of colitis. WT mice had extensive inflammation and tissue damage compared with dKO mice as suggested by histological assessment and myeloperoxidase activity. In conclusion, these results suggest an overriding role of MMP-9 in mediating tissue injury compared with the protective role of MMP-2 in development of colitis. Thus inhibition of MMP-9 may be beneficial in treatment of colitis even if resulting in inhibition of MMP-2.

Abstract
AIM: To evaluate the protective effects of ilomastat, an exogenous matrix metalloproteinase (MMP) inhibitor, on trinitrobenzenesulfonic acid (TNB)-induced ulcerative colitis (UC) in rats.
METHODS: Male SD rats were randomly divided into model group, protective groups A and B, and normal control group. Rats in the model group received only intra-colonic TNB. Rats in the protective groups A and B received intra-peritoneal ilomastat of 10 mg/kg and 20 mg/kg, respectively, beside TNB. Rats in the normal control group received only intra-colonic normal saline. After 3 wk, segments of colon were obtained. RT-PCR and immunohistochemistry were used to examine the expression of MMP-1 and TIMP-1. Hematoxylin-eosin (HE) staining was used for pathological study.
RESULTS: The model of UC was successfully induced in rats. Inflammation of colonic mucosa greatly improved in protective groups A and B. Expression of MMP-1 and TIMP-1 in the model group, protective groups A and B was significantly higher than that in the normal control group (P < 0.0001) with MMP-1 expression increased more significantly than TIMP-1 expression. Expression of MMP-1 in protective groups A and B was significantly lower than that in the model group (P < 0.0001) . Expression of MMP-1 in protective group B was significantly lower than that in protective group A (P < 0.0001).
CONCLUSION: Ilomastat improves TNB-induced UC in rats by inhibiting the MMP-1 activity.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are a family of metal-dependent enzymes responsible for the degradation and remodeling of extracellular matrix and basement membrane proteins that occurs during both normal physiologic activity and disease. It has been suggested that MMPs may also play a role in the pathogenesis of inflammatory bowel disease (IBD) by mediating mucosal breakdown in response to an enhanced inflammatory cascade. We previously demonstrated that elevated urinary MMP levels are independent predictors of disease status in cancer patients. Here we demonstrate that elevated urinary MMP levels may be biomarkers of disease activity in patients with IBD. METHODS We analyzed 95 urine samples prospectively collected from 55 children and young adults with known or suspected IBD who presented for evaluation to the Gastrointestinal Procedure Unit at Children's Hospital Boston. Urinary MMPs were analyzed in patients by zymography and compared to 40 age- and sex-matched controls. RESULTS Urinary MMP levels were significantly elevated (P < 0.0001) in patients with IBD, as well as in each subgroup (Crohn's disease or ulcerative colitis), relative to controls. Multiple logistic regression revealed that urinary MMP-2 and MMP-9 NGAL levels were independent predictors of Crohn's disease and ulcerative colitis (P < 0.0001). CONCLUSIONS These data are the first to demonstrate that urinary MMPs may represent novel noninvasive biomarkers for use in the evaluation of patients with IBD.

Abstract
AIM: To evaluate the effect of a matrix metalloproteinase (MMP) inhibitor, phenan-throline, on colonic inflammation in experi-mental colitis induced by trinitrobenzene sulfonic acid (TNBS) in rats.
METHODS: A rat model of experimental colitis was induced by administration of TNBS. Animals were divided into 3 groups, treated with 1, 10-phenanthroline (20 mg/kg per day), sulphasalazine, and double distilled water (1 mL, control group), respectively. All the animals were killed after 7 days. Myeloperoxidase (MPO) activity was assessed; the mRNA expression of MMP-1, MMP-2, MMP-3 and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in colon tissues were detected by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Meanwhile, MMP-3 and TIMP-1 proteins expression were analyzed by immunohistochemistry.
RESULTS: The absorbency value of MPO in the SASP group or phenanthroline group was significantly lower than that in the control group (0.25 ± 0.15, 0.16 ± 0.09 vs 0.48 ± 0.34, P = 0.025, 0.004). The expression levels of MMP-1, MMP-2 and MMP-3 mRNA had no markedly difference between the SASP group (0.19 ± 0.11, 0.35 ± 0.21, 0.25 ± 0.16) and phenanthroline group (0.33 ± 0.19, 0.29 ± 0.16, 0.22 ± 0.17); however, they were lower than those in the control group (0.45 ± 0.23, 0.53 ± 0.17, 0.62 ± 0.15; P = 0.002, 0.020, 0.000). There was no significant difference in TIMP-1 mRNA and protein among the three groups. However, the expression of MMP-3 protein in the SASP group or phenanthroline group was lower than that in the control group (2971.3 ± 1036.5, 2507.7 ± 1101.0 vs 7812.8 ± 4761.6, P = 0.000).
CONCLUSION: Phenanthroline may treat TNBS-induced colitis in rats by down-regulating MPO activity and MMP-1, MMP-2 and MMP-3 expression, but it has no effect on TIMP-1 expression.

Abstract
Matrilysin [matrix metalloproteinase 7 (MMP7)] is induced by mucosal injury of many tissues. To assess function of this proteinase, we subjected wild-type and Mmp7(-/-) mice to acute colon injury. When matrilysin expression was increasing, 73% of wild-type mice died, whereas only 32% of Mmp7(-/-) mice succumbed. Although re-epithelialization was delayed in Mmp7(-/-) mice, overall injury did not differ markedly between genotypes. We hypothesized that differences in acute inflammation caused increased mortality in wild-type mice. Indeed, whereas overall neutrophil influx into tissue was similar in wild-type and Mmp7(-/-) mice, their location and extent of migration differed between genotypes. Neutrophils were dispersed throughout the mucosa and within the lumen of wild-type mice, but these leukocytes were largely confined to the submucosa in Mmp7(-/-) mice. The levels of neutrophil chemokines, keratinocyte-derived chemokine and MIP-2, increased in the colon tissue of both genotypes, but these factors were detected only in lumenal lavages of wild-type mice. Our findings indicate that matrilysin mediates beneficial and deleterious effects in response to injury. On one hand, it promotes re-epithelialization, but it also controls the transepithelial influx of neutrophils, which if excessive, can lead to tissue damage.

Abstract
BACKGROUND AND PURPOSE Leukotriene B(4) (LTB(4)), formed by the sequential actions of the 5-lipoxygenase (5-LO) and leukotriene A(4) hydrolase (LTA(4)H), is a pro-inflammatory mediator implicated in the pathogenesis of inflammatory bowel disease. However, inhibitors of 5-LO have not proved to be consistent in their therapeutic efficacy in colitis. Another approach to inhibiting LTB(4) synthesis is through the use of inhibitors of LTA(4)H, such as the novel, potent and selective compound, JNJ 26993135. EXPERIMENTAL APPROACH The effect of oral administration of JNJ 26993135 has been evaluated in a rat model of colitis provoked by colonic instillation of trinitrobenzenesulphonic acid (TNBS). The extent and severity of the macroscopic inflammatory response, the colonic levels of myeloperoxidase (MPO) and LTB(4) and of the pro-inflammatory cytokines, tumour necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were measured. KEY RESULTS Oral administration of JNJ 26993135 (5, 15 and 30 mg kg(-1), twice a day) dose-dependently reduced both the extent and intensity of the colonic inflammatory damage observed 3 days after TNBS challenge. JNJ 26993135 also dose-dependently reduced the elevated colonic levels of LTB(4), as well as the inflammatory biomarkers, MPO, IL-6 and TNF-alpha. This dosing regimen was supported by the pharmacokinetic profile of JNJ 26993135, along with the demonstration of the inhibition of ex vivo production of LTB(4) in whole blood following oral administration. CONCLUSIONS AND IMPLICATIONS These results with JNJ 26993135 in the rat TNBS model support the role of LTB(4) in colitis and the potential value of targeting LTA(4)H for the treatment of inflammatory bowel diseases.

Abstract
BACKGROUND AND OBJECTIVE Matrix metalloproteinases are associated with matrix turnover in both physiological and pathological conditions. We postulate an association between aberrant matrix metalloproteinases proteolytic activity and the intestinal tissue destruction, seen in patients with Crohn's disease and/or ulcerative colitis. MATERIALS AND METHODS Surgically resected inflamed and non-inflamed ileum and colon with/without extensive fibrosis from 122 Crohn's disease, 20 ulcerative colitis and 62 control patients were homogenized. Protein levels of matrix metalloproteinases and tissue inhibitor of metalloproteinases were measured by enzyme-linked immunosorbent assays (ELISA), while matrix metalloproteinases and myeloperoxidase activity were measured by specific activity assays. RESULTS Expression of total levels of matrix metalloproteinases-1, -2, -3 and -9 relative to tissue inhibitor of metalloproteinases-1 and -2 was increased in inflamed inflammatory bowel disease compared to non-inflamed inflammatory bowel disease and control intestinal mucosa. Also, net matrix metalloproteinases-1, -2, -3 and -9 activity in inflamed inflammatory bowel disease was increased, with similar expression profiles in Crohn's disease and ulcerative colitis. Within inflamed inflammatory bowel disease, a close correlation of matrix metalloproteinases with myeloperoxidase was observed. The expression of matrix metalloproteinases and tissue inhibitor of metalloproteinases was similar in inflamed Crohn's disease tissue with or without extensive fibrosis and not related to fistulizing disease. CONCLUSIONS We have shown increased net matrix metalloproteinases activity in intestinal inflammatory bowel disease tissue, likely to contribute to the tissue damage and remodelling seen in inflammatory bowel disease.

Abstract
BACKGROUND Previous studies have shown an upregulation of matrix metalloproteinases (MMPs) in intestinal tissue of patients with inflammatory bowel disease (IBD) and significant clinical improvement after administration of the anti-TNF-a antibody infliximab. The aims of our study were to determine expression and secretion of MMP-1, -2, -3, -9, and their inhibitors TIMP-1, -2 by IBD versus control intestinal mucosa ex vivo and to assess the regulatory capacity by infliximab of the proteolytic phenotype. METHODS Intestinal mucosal explants from 20 IBD and 15 control patients were cultured with or without infliximab and/or the T-cell activator pokeweed mitogen (PWM). Explants and culture supernatants were analyzed for MMPs, TIMPs, and TNF-alpha protein, activity and/or mRNA levels. All patients were genotyped for functional TNF-alpha, MMP, and TIMP single nucleotide polymorphism (SNP) loci. RESULTS Expression of MMP and TIMP protein/activity in basal medium was higher in IBD versus control explants. Dependent on genotype at SNP loci, infliximab downregulated MMP-1, -3, and -9 relative to TIMP-1 and -2 and also decreased MMP-1 and -3 activities, while PWM enhanced these levels, partly counteracted again by infliximab. The expression of MMP-2 relative to TIMP did not change by treatment with infliximab and/or PWM. CONCLUSIONS The high expression of MMPs in patients with IBD suggests a role for these proteinases in the pathogenesis of this disease. Infliximab seems to induce a genotype-associated matrix protective phenotype, which may contribute to the observed therapeutic efficacy of this drug in IBD, particularly at the mucosal surface.

Abstract
Matrix metalloproteinases (MMPs) are a family of Zn(2+)-dependent extracellular matrix (ECM) degrading endopeptidases that share common functional domains, activation mechanisms, and collectively have the capacity to degrade all types of ECM proteins. In addition to playing a central role in ECM turnover, MMPs proteolytically activate or degrade a variety of nonmatrix substrates including chemokines, cytokines, growth factors, and junctional proteins. Thus, they are increasingly recognized as critical players in inflammatory response. Indeed, accumulating data from several studies indicate that they are the predominant proteases involved in the pathogenesis of inflammatory bowel disease (IBD) via their influence on the function and migration of inflammatory cells, mucosal ulceration, as well as matrix deposition and degradation. Some MMPs are constitutively expressed and play a protective role in IBD through their effect on cellular homeostasis, while others are induced during inflammation-mediated tissue damage. This article focuses on the role of the various MMPs in IBD, discussing their physiologic and pathogenetic role in the context of intestinal defense, mucosal inflammatory response, and immune cell-epithelial interaction.

Abstract
OBJECTIVE Tumor necrosis factor (TNF)-alpha-converting enzyme (TACE), which has been purified, regulates maturity of TNF-alpha. Matrix metalloproteinases (MMPs) play a key role in various inflammatory conditions. The incidence of intestinal damage has increased, but the mechanism and treatment have not been well understood. The purpose of this study was to investigate the roles of TACE and MMP in indomethacin (Indo)-induced intestinal damage as well as the therapeutic effects of TACE inhibitor and selective MMP inhibitor (sMMPi) on this intestinal damage in rats. MATERIAL AND METHODS In the first experiment, serial changes in intestinal ulcers and the production of MMP were investigated. In the second experiment, we assessed the effect of three TACE and/or MMP inhibitors and the production of TNF-alpha, TACE, MMP-3, -9 and tissue inhibitor of MMP (TIMP)-1. The rats were divided into five groups: a control group, and four groups that received Indo alone, Indo plus TACE inhibitor (GM6001), Indo plus a selective MMP-3 inhibitor and Indo plus an MMP-9/13 inhibitor, respectively. RESULTS MMP-3 was overexpressed at 24 h after Indo administration, when intestinal injury was most prominent macroscopically and microscopically. GM6001 significantly decreased ulcer severity and suppressed MMP-3 in a dose-dependent fashion. The selective MMP-3 inhibitor dose-dependently ameliorated intestinal damage to the same degree as GM6001, but the MMP-9 inhibitor had no effect on the injury. CONCLUSIONS MMP-3 inhibition ameliorates intestinal damage without apparently affecting either TNF-alpha or TACE production and the dose-response curve suggests that the beneficial effect of the so-called TACE inhibitor is actually mainly mediated via MMP-3 inhibition rather than TNF-alpha inhibition.

Abstract
AIM: To study whether matrix metalloproteinase-9 (MMP-9) is a key factor in epithelial damage in the dextran sodium sulphate (DSS) model of colitis in mice.
METHODS: MMP-9-deficient and wild-type (wt) mice were given 5% DSS in drinking water for 5 d followed by recovery up to 7 d. On d 5 and 12 after induction of colitis, gelatinases, MMP-2 and MMP-9, were measured in homogenates of colonic tissue by zymography and Western blot, whereas tissue inhibitor of metalloproteinases (TIMPs) were measured by reverse zymography. The gelatinolytic activity was also determined in supernatants of polymorphonuclear leukocytes (PMN) isolated from mice blood. Moreover, intestinal epithelial cells were stimulated with TNF-α to study whether these cells were able to produce MMPs. Finally, colonic mucosal lesions were measured by microscopic examination.
RESULTS: On d 5 of colitis, the activity of MMP-9 was increased in homogenates of colonic tissues (0.24 ± 0.1 vs 21.3 ± 6.4, P < 0.05) and PMN from peripheral blood in wt (0.5 ± 0.1 vs 10.4 ± 0.7, P < 0.05), but not in MMP-9-deficient animals. The MMP-9 activity was also up-regulated by TNF-α in epithelial intestinal cells (2.5 ± 0.5 vs 14.7 ± 3.0, P < 0.05). Although colitis also led to increase of TIMP-1 activity, the MMP-9/TIMP-1 balance remained elevated. Finally, in the MMP-9-deficient colitic mice both the extent and severity of intestinal epithelial injury were significantly attenuated when compared with wt mice.
CONCLUSION: We conclude that DSS induced colitis is markedly attenuated in animals lacking MMP-9. This suggests that intestinal injury induced by DSS is modulated by MMP-9 and that inhibition of this gelatinase may reduce inflammation.

Abstract
The effects of the inhibitors of glycogen synthase kinase-3beta (GSK-3beta), TDZD-8 and SB 415286, which can substantially reduce the systemic inflammation associated with endotoxic shock in vivo, have now been investigated on the acute colitis provoked by trinitrobenzene sulphonic acid (TNBS) in the rat. Administration of the GSK-3beta inhibitor TDZD-8 (0.1, 0.33 or 1.0 mg kg-1, s.c., b.i.d., for 3 days) caused a dose-dependent reduction in the colonic inflammation induced by intracolonic TNBS assessed after 3 days, both as the area of macroscopic involvement and as a score using 0-10 scale. Likewise, following administration of the GSK-3beta inhibitor SB 415286 (0.1, 0.33 or 1.0 mg kg-1, s.c., b.i.d., for 3 days), the extent and degree of the TNBS-provoked colonic inflammation was reduced. Administration of either TDZD-8 or SB 415286 reduced the fall in body weight following challenge with TNBS at each dose level studied. The increase in myeloperoxidase activity, an index of neutrophil infiltration into the TNBS-induced inflamed colon, was significantly inhibited by both TDZD-8 and SB 415286 at each dose level. The increase in the levels of the proinflammatory cytokine, TNF-alpha, in the inflamed colon was also significantly inhibited by either compound at the highest doses evaluated. The elevated levels of the transcription factor NF-kappaB subunit p65, as determined by Western blot in the nuclear extracts from the TNBS-provoked inflamed colonic tissue, were dose-dependently reduced by TDZD-8 or SB 415286 treatment. These findings demonstrate that two chemically distinct selective inhibitors of the activity of GSK-3beta reduce the inflammation and tissue injury in a rat model of acute colitis. The mechanisms underlying this anti-inflammatory action may be related to downregulation of NF-kappaB activity, involved in the generation of proinflammatory mediators.

Abstract
Matrix metalloproteinases (MMPs) and their endogenous inhibitors, tissue inhibitors of MMPs (TIMPs), are produced in the gastrointestinal tract by several structural cells. The balance between MMPs and TIMPs is essential for many physiological processes in the gut. However, imbalance between MMPs and TIMPs plays an important role in the pathophysiology of diverse intestinal inflammatory conditions. We reviewed the role of the MMP/TIMP system in the pathogenesis of intestinal inflammatory diseases and pharmacologic perspectives for the use of compounds that restore the MMP/TIMP balance.

Abstract
Extracellular matrix dynamics, crucial for tissue remodelling, are highly regulated by a cascade of matrix metalloproteinases (MMPs) during inflammation and wound healing processes in inflammatory bowel disease (IBD). Contrary to expectations, there are limited reports to date that MMP inhibitors have some beneficial therapeutic effects in experimental colitis models. Furthermore, clinical trials of MMP inhibitors against certain tumours have failed to show any therapeutic benefit. One major reason for this lack of success may be the apparent uncertainty about the precise spectrum of inhibitory activity required. Since tumour necrosis factor alpha (TNFalpha), a key mediator in colonic inflammation, promotes MMP production in a dose-dependent manner, the therapeutic success of anti-TNFalpha agents against IBD motivated us to re-evaluate the therapeutic potential of MMP inhibition. First, using a quantitative polymerase chain reaction (PCR), western blotting, and zymography, we determined which MMPs were relevant to experimental colitis induced in mice by dextran sulphate sodium. Next, we examined a distinct role for MAPK and NFkappaB signalling pathways in the regulation of the expression of these MMP genes. Finally, we examined whether transcriptional regulation of these MMPs, either indirectly using inhibitors of MAPK and/or NFkappaB signalling pathways or directly using siRNA directed against these MMPs, contributes to the prevention of colitis. Changes in the expression level of colonic MMP-3 and MMP-10 preceded the clinical course of colitis. Colitis improved in mice that received these signal inhibitors, together with suppression of MMP expression. Moreover, siRNA that targeted MMP-3 and MMP-10 effectively reduced both the transcription of these MMPs and the severity of colitis. We conclude that MMP-3 and MMP-10 play a causal role in excess tissue destruction in colitis. Specific inhibition of these MMPs should provide novel therapeutics against IBD.

Abstract
Recent evidence demonstrates that the increased expression and activity of matrix metalloproteinases (MMPs) may contribute to intestinal tissue injury and inflammation in inflammatory bowel disease, and that MMP inhibition might be a new therapeutic approach to controlling inflammatory response. In addition, MMPs may play a crucial role in physiological and pathophysiological reactions such as leukocyte accumulation into inflamed tissue, cytokine production from inflammatory and epithelial cells, T lymphocyte homing to the intestine, wound healing and proliferation of epithelial cells, and intestinal innate immunity. This review focuses on recent progress in elucidating the biological and pathological roles of MMPs in inflammatory bowel disease.

Abstract
The histamine H(4) receptor is a G-protein coupled receptor with little homology to the pro-inflammatory histamine H(1) receptor, expressed on cells of the immune system with hematopoietic lineage such as eosinophils and mast cells. The effects of the recently described highly selective histamine H(4) receptor antagonists JNJ 10191584 and JNJ 7777120 have now been investigated on the acute colitis provoked by trinitrobenzene sulphonic acid over 3 days in the rat. Treatment with JNJ 10191584 (10-100 mg/kg p.o., b.i.d.) caused a dose-dependent reduction in macroscopic damage, inhibition of the TNBS-provoked elevation of both colonic myeloperoxidase and tumour necrosis factor-alpha (TNF-alpha), and a reduction in the histologically assessed increase in mucosal and submucosal thickness and neutrophil infiltration. JNJ 7777120 (100 mg/kg p.o., b.i.d.) likewise reduced the macroscopic injury and the increases in colonic myeloperoxidase and TNF-alpha levels. These findings indicate a pro-inflammatory role for the histamine H(4) receptor in this model and suggest a novel pharmacological approach to the treatment of colitis.

Abstract
Secretory phospholipase A(2) (sPLA(2)) enzymes have been implicated in the pathogenesis of human inflammatory bowel disease (IBD). In this study we compared the efficacy of a potent, new and highly selective inhibitor of group IIa human sPLA(2) enzyme (5-(4-benzyloxyphenyl)-4S-(7-phenylheptanoylamino)-pentanoic acid; sPLA(2)I), with that of sulfasalazine, in a rat model of trinitrobenzene sulfonic acid (TNBS)-induced colitis. Following a single oral dose of sPLA(2)I (5 mg/kg), pharmacoactive levels of drug were detected in the serum within 15 min and for up to 24 h by liquid chromatography mass spectrometry analysis. Rats treated with sPLA(2)I (5 mg/kg/day) prior to induction of colitis were significantly healthier than TNBS-alone rats, as shown by reduced mortality, improved food intake and increased body weight, and significantly reduced colon myeloperoxidase levels, edema, tumour necrosis factor-alpha levels, and colon macroscopic pathology scores after 8 days. Rats pretreated with sulfasalazine (100 mg/kg/day) also had reduced disease expression markers similar to the sPLA(2)I, but exhibited no improvement in colon edema. This study supports a role for the group IIa sPLA(2) enzyme in pathology associated with the TNBS rat model of IBD, and suggests a possible therapeutic application for selective inhibitors of group IIa sPLA(2) inhibitors in the treatment of IBD.

Abstract
Primary sensory neurons are important in regard to the initiation and propagation of intestinal inflammation. The vanilloid receptor subtype-1 (VR-1) is a cation channel located on the sensory nerves that, when stimulated, release proinflammatory peptides. Previous reports have indicated that inhibition of VR-1 with capsazepine (CPZ), a VR-1 antagonist, attenuates dextran sodium sulfate (DSS) colitis in rats. DSS-induced colitis resembles ulcerative colitis with regard to its pathologic features. In this study, we examined the effect of CPZ on trinitrobenzene sulfonic acid (TNBS)-induced colitis, an experimental model of intestinal inflammation that most closely resembles the histologic and microscopic features of Crohn's disease. Colitis was induced by administering a single enema of 100 mg/kg TNBS in 50% ethanol via catheter to lightly anesthetized rats. Subsets of rats were treated with either 1 micromol/kg/ml of CPZ or CPZ-vehicle via enema for 6 days. Seven days after TNBS administration, rats were sacrificed and inflammation was assessed using a validated macroscopic damage score (MDS) and by measuring myeloperoxidase (MPO) activity. In addition, histologic examination was performed. TNBS administration resulted in reproducible chronic erosive lesions extending into the muscularis propria and extensive recruitment of neutrophils in the distal colon. MDS and MPO scores were considerably elevated in the TNBS colons when compared with the TNBS vehicle animals. TNBS rats treated with CPZ enemas exhibited a substantial reduction in MDS and MPO scores and demonstrated dramatically improved pathologic findings. Topical CPZ resulted in considerable attenuation of TNBS-induced colitis. These results support the role of VR-1 and sensory neurons with regard to intestinal inflammation.

Abstract
AIM: Overexpression of mucosal metalloproteinases (MMP) have been demonstrated recently in inflammatory bowel disease. Their activity can be counterbalanced by the tissue inhibitor of metalloproteinases (TIMP). The aim of this study was to evaluate the effect of ulcerative colitis (UC) on MMP-1 and TIMP-1 plasma concentrations, as two possible biomarkers of the disease activity.
METHODS: MMP-1 and TIMP-1 plasma concentrations were measured with an enzyme immunoassay in 16 patients with endoscopically confirmed active UC.
RESULTS: Plasma concentrations of both MMP-1 (13.7 ± 0.2 ng/ml) and TIMP-1 (799 ± 140 ng/ml) were significantly elevated in UC patients in comparison to healthy controls (11.9 ± 0.9 ng/ml and 220 ± 7 ng/ml respectively). There was no correlation between TIMP-1 and MMP-1 concentrations (r = -0.02). TIMP-1 levels revealed significant positive correlations with scored endoscopic degree of mucosal injury, disease activity index and clinical activity index values as well as C-reactive protein concentration. There was no correlation between MMP-1 and laboratory, clinical or endoscopic indices of the disease activity.
CONCLUSION: These results confirm the role of both MMP-1 and TIMP-1 in the pathogenesis of ulcerative colitis. However only TIMP-1 can be useful as a biomarker of the disease activity, demonstrating association with clinical and endoscopic pictures.

Abstract
OBJECTIVE To characterize the morphologic and immunologic features of adherent synovial fluid cells derived from patients with rheumatoid arthritis (RA), and to explore their potential function in vitro and in vivo by focusing on cartilage destruction. METHODS Synovial fluid adherent cells obtained from patients with RA and from control subjects were characterized by immunohistochemistry, flow cytometry, and electron microscopy. In vitro, these cells were cultured in the presence of cartilage particles. Cartilage destruction was monitored by the release of sulfated glycosaminoglycans (sGAG) into the medium, and the level of matrix metalloproteinase 1 (MMP-1) in the cell culture supernatant was measured by enzyme-linked immunosorbent assay. To inhibit cartilage destruction in vitro, the MMP inhibitor marimastat was tested in this system. In vivo, in the SCID mouse coimplantation model, RA synovial fluid adherent cells and RA synovial fibroblasts (as positive controls) were coimplanted with human cartilage under the kidney capsule and maintained there for 60 days. RESULTS In vitro, the synovial fluid adherent cells consisted of 2 subpopulations, large round-shaped macrophage-like cells (CD68+) and spindle-shaped fibroblast-like cells (Thy-1+). When passaged, the latter cells proliferated and organized themselves into 3-dimensional formations. This allowed them to reach collagen particles fixed with agarose. Fibroblasts derived from synovial tissues could not be used in this assay because they grew only in monolayers and not on agarose. The majority (>90%) of passaged RA synovial fluid adherent cells expressed the Thy-1+,CD45-,CD68-,CD86- phenotype. Electron microscopy did not reveal important morphologic differences between the 2 types of fibroblasts, those from synovial tissue or those from synovial fluid. However, synovial fluid adherent cells expressed lower levels of adhesion molecules, including CD54 and galectin 3, as well as the complement-regulatory molecule CD55. The in vitro release of sGAG associated with cell activity was 2.5-fold higher from RA synovial fluid adherent cells in comparison with that from negative control cells. The release of sGAG correlated with the concentration of MMP-1 and was inhibited by the broad-range MMP inhibitor marimastat in a dose-dependent manner. RA synovial fluid adherent cells coimplanted with cartilage in SCID mice showed the same invasive behavior as that displayed by tissue-derived RA synovial fibroblasts. CONCLUSION Similar to tissue-derived RA synovial fibroblasts, RA synovial fluid adherent cells, which contain "floating" anchorage-independent fibroblast-like cells, mediate cartilage destruction independent of the hyperplastic synovial tissue.

Abstract
OBJECTIVE To characterize the clinical and histopathologic changes in a rat model of broad-spectrum matrix metalloproteinase (MMP)-induced musculoskeletal syndrome (MSS), and to facilitate research into the causes and treatments of MSS in humans. METHODS Male Lewis rats weighing 150-180 gm were administered 10-30 mg of the broad-spectrum MMP inhibitor marimastat over a 2-week period via surgically implanted subcutaneous osmotic pumps. The animals were monitored and scored for the onset and severity of MSS, using clinical and histologic parameters. RESULTS Marimastat-treated rats exhibited various clinical signs, including compromised ability to rest on their hind feet, high-stepping gait, reluctance or inability to move, and hind paw swelling. Histologically, marimastat-treated rat joints were characterized by soft tissue and bone changes, such as increased epiphyseal growth plate, synovial hyperplasia, and increased cellularity in the joint capsule and extracapsular ligaments. The severity of MSS, as judged by clinical criteria (2 blinded observers using 3 clinical parameters), paw volume, and histologic score, was nearly identical. The observed changes were indistinguishable from those reported for primate models and mimic MSS in humans. CONCLUSION This simple and sensitive model of MSS is an attractive alternative for studying the pathology of MSS.

Abstract
AIM To determine the expression and distribution of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) in the normal human iris and ciliary body. METHODS Seven postmortem human eyes were fixed with formalin. The iris and ciliary body were dissected out and embedded in paraffin. The expression of MMPs -1, 2, 3, and 9, and TIMPs 1-4 in the iris and ciliary body was determined by a novel immunofluorescence technique and the results graded by masked observers. RESULTS Positive staining for MMPs and TIMPs was observed in all regions of the anterior uvea, and was more intense in the ciliary body than in the iris. Most MMPs and TIMPs showed similar patterns in their distribution. In the ciliary body, staining was strongest in the epithelium, and was localised to the epithelial cell cytoplasm, except for TIMP-3 which was strongly expressed in the basement membranes. In the iris, staining was most noticeable in the anterior border and anterior epithelial layer. Blood vessels in the stroma of the iris and ciliary body also stained moderately for MMPs and TIMPs. CONCLUSION Both MMPs and TIMPs are widely expressed in the anterior uvea, with a positive correlation between their expressions. Their differential localisation in the ciliary body suggests they may have a role in maintaining homeostasis in the uveal tract.
