Повний текст джерелаThe course of pediatric-onset inflammatory bowel disease (Crohn’s diseae, ulcerative colitis and IBDD unclassified) can be complicated by structural or functional sequelae. Structural complications include intestinal fibrosis which can cause bowel strictures. IBD can be associated with functional abdominal pain persisting despite remission of inflammation. The purpose of our work was to determine the burden of these complications and search for association with previous severity of inflammation, based on!two clinical studies and two animal models. In the first study, TFI-MICI, we showed that 20% of children and adolescents with IBD in clinical and biochemical Remission had functional gastrointestinal disorders, among which 15% had functional abdominal pain disorders (FAPD). FAPD was! Ssociated with increased fatigue, depressive symptoms and reduced quality of life, but not with anxiety. There was no association between the severity of IBD and presence of FAPD. The second study, STENO-PED, focused on imaging and clinical predictors of response!to treatment in children and adolescents with stricturing small bowel Crohn’s disease. We showed that the predictors for surgery were a dilation proximal to the stricture of >30mm, and a PCDAI score at diagnosis of stricture > 22.5. Receiving an anti-TNFα treatment after diagnosis of stricture was a protective factor from surgery. Experimental models allowing to follow the progression of fibrosis along with inflammation and assess response to Treatment are lacking, in particular for pre-pubertal animals. We adapted to Sprague-Dawley pre-pubertal rats a model of acute (1 dose of! TNBS) and chronic (3 doses of TNBS) hapten-induced colitis. The rats in both models developed significant inflammation, based on histology and magnetic resonance colonography. Rats in the chronic colitis model developed histologic fibrosis. There was a non-significant trend to fibrosis in the acute model. !We treated rats in both models with MODULEN IBD® from induction of colitis to collection of colonic samples. This treatment did not reverse inflammation nor fibrosis. Fibrosis and functional abdominal pain in pediatric-onset IBD are two important problems, although functional pain appeared to be not more frequent than in the general population. Animal models could be of great assistance in order to better decipher the link between inflammation and fibrosis, and see if an effective early suppression of inflammation along with new anti-fibrotic therapies could halt the progression of fibrosis

Повний текст джерелаInflammatory bowel disease (IBD), both ulcerative colitis (UC) and Crohn’s disease (CD), face an increased risk of colorectal cancer (CRC). CRC develop from a precursor lesion, dysplasia. In contrast to sporadic colorectal carcinogenesis, less is known about molecular mechanisms and genetic alterations underlying colorectal carcinogenesis complicating IBD. Moreover, most data in the literature are focused on UC. The aim of this work was to better characterize intestinal neoplasias complicating IBD from a pathological and molecular point of view. We observed similar frequencies of dysplasia adjacent to and distant from CRC in both CD and UC. We showed that the microsatellite instability (MSI) phenotype, a phenotype due to mismatch repair (MMR) genes defects, was involved in a significant part of these neoplasias. The mechanisms underlying MMR deficiency in the setting of IBD were different from those in sporadic MSI CRC and seemed to be more related to those observed in hereditary MSI CRC. In contrast, the mechanisms of tumoral progression seemed to be similar to those of other MSI tumors. At least, we showed that MGMT (O6 methylguanine-DNA methyltransferase) field defect, a repair gene not belonging to the MMR system, may be a crucial initiating step prior to MMR deficiency in the development of MSI CRC arising in different clinical contexts (sporadic, inherited, and IBD-associated CRC)

Повний текст джерелаIn recent years, the involvement of intestinal microbiota in the pathogenesis of inflammatory bowel disease (IBD) has been established. The aim of our study was to determine the impact of dysbiosis in intestinal ecosystem of IBD patients.These three studies allowed us to confirm the fundamental role of IBD-associated dysbiosis. First, IBD-associated dysbiosis has been identified as a potential predictive tool of relapse, before local or systemic inflammation. Second, IBD-associated dysbiosis has been involved as an actor in the emergence of an imbalance of intestinal ecosystem. This imbalance was characterised by an alteration of microbiota enzymatic activity leading to modifications in the luminal bile acid pool composition and may affect the anti-inflammatory effects of some bile acids on gut epithelial cells and could participate in the chronic inflammation loop of IBD. Moreover, a deficiency in the antimicrobial defense systems of defensins may be an explanation for the break of the antibacterial barrier function in inflammatory bowel diseases maintaining dysbiosis.These results reinforce the prominent role of the microbiota in the development of IBD and suggest that restoring normobiosis could be a new goal for optimal IBD management

Повний текст джерелаPainful sensation is a hallmark of the inflammatory response induced by the infection by pathogens or tissue damage. Pro-inflammatory mediators released during inflammation directly activate primary sensory neuron to initiate painful message. This painful message is regulated in situ via the secretion of opioids by effectors CD4+ T lymphocytes generated in response to the pathogen. The analgesic properties of the CD4+ T lymphocytes are acquired upon activation by antigen loaded-dendritic cells in the draining lymph nodes via the de novo synthesis of enkephalin. Enkephalins are released by effector CD4+ T lymphocytes upon their arrival at the site of inflammation after new antigen stimulation with the cognate antigen. A defective regulation of CD4 + T cells in the intestinal mucosa can lead to the development of inflammatory bowel disease (IBD). My work shows in mice that Th1 and Th17 effector CD4+ T lymphocytes that are associated with IBD produce enkephalins. Using colorectal distension, I demonstrate that, during the acute phase of colitis, characterized by the activation of innate immune cells, mice exhibit visceral hypersensitivity. This hypersensitivity disappears in the later stages of the disease, when T cells infiltrate the inflamed mucosa. This inhibition of visceral hypersensitivity is dependent on the activation of the peripheral opioid receptors by the local release of enkephalins by CD4+ T cells. The intensity of visceral hypersensitivity appears to correlate with the rate of infiltration of the mucosa by T cells rather than the extent of tissue damage. This observation led us to develop a new anti-nociceptive strategy based on the recruitment of T cells at the early phase of colitis. The strategy that we adopted to accelerate the recruitment of T cells to the site of inflammation, was based on the establishment of a secondary immune response. I showed immunization of mice allowed, during a second exposure of to the antigen in the inflammatory site, reduce inflammatory visceral pain. This analgesic strategy was effective in both models of visceral pain that I have studied, the DSS-induced colitis in mice, and the cyclophosphamide-induced interstitial cystitis in rats. The use, in my protocol, of vaccines commonly used in human medicine allows considering rapid application in humans

Повний текст джерелаInflammatory Bowel Diseases (IBD) are a major public health issue in industrialized and newly-industrialized countries. Crohn’s disease (CD) and Ulcerative Colitis (UC) both present intestinal dysbiosis and chronic inflammatory responses towards members of the microbiota. Secretory Ig (SIg), SIgA and SIgM, are inducers of immune tolerance towards this microbiota. In humans, only SIgA2 can uptaken by M cells of the Peyer’s Patches and transported to the mucosa with their antigens. This reverse transcytosis (RT) is dependent on Dectin-1 and Siglec-5 binding. We show that SIgM can also undergo RT and IgA sub-class and isoform condition dendritic cell phenotypes and affinity for each IgA receptor is key for these interactions. In IBD, we uncover pathogenic functions on IgA1-induced selection of the microbiota in CD, and loss of function of IgA2 for microbiota selection in UC. Finally, we show that Dectin-1 ligands can limit RT in vivo in mouse models of colitis and thus limit inflammation. This work offers new avenues regarding the understanding of dysbiosis maintenance et provides novel therapeutic approaches in the care for IBD. It can be transposed in other metabolic disease wherein dysbiosis promotes inflammation, such as type 2 diabetes and obesity

Повний текст джерелаInflammatory Bowel Disease (IBD) patients, such as Crohn's disease or ulcerative colitis suffer from chronic and relapsing intestinal inflammation that favours the development of colitis associated cancer (CAC). This inflammation is initiated by aberrant activations of the innate immune responses associated to intestinal barrier defects. The conventional medical therapies consist to decrease the inflammatory response, which also decrease the risk of colon carcinoma but lead to severe side-effects. Recently, a number of animal studies have demonstrated that innate immune responses are attenuated by stimulation of the efferent arm of vagus nerve (VN) through its neurotransmitter acetylcholine (ACh) that acts on resident macrophages α7 nicotinic receptor (α7 nAChR). ACh also acts as a signalling molecule in epithelial cells through cholinergic receptors such as nAChR or muscarinic (mAChR) receptors. In the current study, we aimed to extend these findings to CAC prevention by treating human adenocarcinoma cell lines through targeting cholinergic receptors with nicotine (which binds nAChR) and ACh (which binds both cholinergic receptors). Using HT-29 and Caco-2 cell lines, we demonstrated that ACh-induced activation of mAChR results in cell dissociation together with changes in expression and localization of intestinal tight and adherens junction proteins. ACh-induced modulation of cell adhesion proprieties correlates with the acquisition of invasive potential. By contrast, nicotine-mediated activation of nAChR maintains epithelial cell organisation. ACh-released by VN stimulation (VNS) could effectively preserve epithelium integrity thus limiting inflammatory response and tumor development. However, attention should be paid on the nature of the cholinergic receptor solicited. Indeed, regarding to the protective effects of nAChR signalling on epithelial cells, activation of mAChR would worsen the disease and led to increase inflammation. These data have important repercussions on the therapeutic potential of VNS in IBD and CAC, which may represent “the yin and yang” of the intestinal homeostasis

Повний текст джерелаThe interaction between microbiota and the epithelium play a key role in establishing and maintaining intestinal homeostasis by the production of factors influencing the environment. The ecto-pantetheinase Vanin-1 (Vnn1) produces pantothenate (vitB5) and cysteamine in the coenzyme A degradation pathway. Using mouse models, we highlighted the role of Vnn1 in intestinal inflammation and we described the overexpression of VNN1 in IBD patients. Thus, VNN1 is a marker of IBD. To understand the impact of Vnn1 expression on intestinal homeostasis, we developed the ViVA transgenic mouse (Villin-Vanin) constitutively overexpressing Vnn1 under the control of the villin promoter. The ViVA mouse is protected from DSS induced colitis with less epithelial damage rather than a reduction of inflammation. A microarray study on microdissected colonocytes allowed us to identify genes expression signatures associated to the preservation of mucosal integrity in the ViVA mouse under DSS treatment and a better health status on ViVA colonocytes at the basal state

Повний текст джерелаTherapeutic antibodies display complex pharmacokinetic properties. When the antigenic mass increases, they are eliminated faster, and thus an active disease is responsible for a fast clearance. Moreover, patients can produce antibodies to the drug, leading to a strongly accelerated clearance. In this work, we studied the variability of the pharmacokinetics and of the concentration-effect relationship of anti-TNFα antibodies in inflammatory bowel diseases (IBD). The intra-individual variability of infliximab was described using compartmental modelling, and the relationship between disease activity and clearance was demonstrated at the individual level. A model was built to detect clearance increases putatively linked to immunogenicity, independently from evidencing any anti-drug antibodies in blood samples, thus avoiding the analytical issues that hampers the detection of immunization. The time-varying pharmacokinetics was comfronted to the clinical response, showing that clearance was predicitive of the respsonse in induction and de-escalation settings. Therefore, it was hypothetized that monitoring the clearance could help the follow-up of the disease, as an early marker of disease activity and evolution. Last, it was shown that cumulated exposure to infliximab was linked to the risk of developping opportunistic infections. Based on this data, recommandations regarding the modalities of regimen adaptations could be built, that are currently lacking. All the work presented here contribute to enhance our knowledge of the pharmacology of anti-TNFα antibodies, but also of other therapeutic antibodies, and to improve their use in clinical settings

Повний текст джерелаInflammatory bowel diseases (IBD), which two major forms are Crohn’s disease and ulcerative colitis, affect 2.2 million people in Europe. They are characterized by the inflammation of all or part of the digestive tract. Recent studies have shown that the endocannabinoid system has a beneficial role against inflammation of the gut through the CB2 receptor and the endocannabinoids. Our work focuses on the development of selective CB2 agonists for the treatment of IBD.First, two series of compounds were designed and synthesized around oxazole and isoxazole heterocycles. Different groups, known to be essential for CB2 agonist activity in previous series, were introduced on these heterocycles. These new compounds were evaluated for their pharmacological activity.Simultaneously, some original pyrimido[5,4-d]- and pyrido[3,2-d]oxazole compounds were synthesized starting from 5-amino-2-phenyloxazole-4-carbonitrile. Indeed, this pattern possesses an enaminonitrile system favorable to cyclisation. Firstly, the synthesis of these new bicycles was optimized. Then, pharmacophoric groups essential for the agonist CB2 activity were introduced to design new potential CB2 receptor agonists based on these bicycles

Повний текст джерелаInflammation is a natural body defence reaction in response to injuries. The clearance of apoptotic cells by macrophages is at the origin of a pro-resolving microenvironment composed of various soluble factors, allow the arrest of the inflammatory response and to initiate tissue repair. The resolution of inflammation is sometimes defective and contributes to the development of chronic inflammatory diseases, such as chronic inflammatory bowel disease (IBD), which include Crohn's disease (CD) and ulcerative colitis (UC). In this context, we propose to evaluate the therapeutic effect of these pro-resolving factors in the treatment of IBD. This factors derived from the culture of macrophages with apoptotic cells, and called SuperMApo (Supernatant issued from Macrophage Apoptotic cell culture) (Patent # WO2014106666-A1, 2013) contains pro-resolving factors similar to those found in the physiological process of inflammatory resolution, and which may be absent or ineffective in these patients.In this work, we have demonstrated the therapeutic effect of SuperMApo using two experimental models of colitis. To assess the relevance of these models to clinical practice, we have implemented flexible video endoscopy. The therapeutic effect of SuperMApo has been shown to decrease the clinical, endoscopic and histological score of colitis mice, accompanied by improved intestinal permeability and mucosal healing in vivo. This therapeutic effect is related in part to reprogramming of antigen presenting cells (APC), in particular cDC and macrophages, which exhibit less response to TLR ligands, promote induction of Treg and inhibit Th1 production. In addition, SuperMApo induces a marked tissue repair of the intestinal mucosa associated with activation of myofibroblasts, the active form of fibroblasts, and the epithelial intestinal cells (IEC). In particular, SuperMApo increases the migration, proliferation and wound healing properties of these two cell types. This effect depends in part on the growth factors contained in SuperMApo such as TGF-β, IGF-I and VEGF. Finally, preliminary results show that SuperMApo induces a repairing state on fibroblasts from patients with IBD. This opens widely the use of SuperMApo as a clinically approach to propose this new therapeutic option to refractory patients suffering from IBD
