Résumé :

Endothelin (ET)-1 has been launched as an important mediator in bronchial asthma, which is an eosinophilic airway inflammation. However, the interplay between ET-1 and other proinflammatory mediators during the development of airway inflammation has not been elucidated. We wanted to study 1) whether the production of ET-1 precedes the production of other proinflammatory mediators and 2) whether ET-1 stimulates the production of these mediators within the airways. These hypotheses were studied during the development of an eosinophilic airway inflammation in rats. The increase in ET-1 mRNA level in lung tissue preceded the increase in mRNA levels of tumor necrosis factor-α, interleukin (IL)-1β, and IL-8. Treatment of the animals with the ET receptor antagonist bosentan resulted in a substantial decrease in the concentrations of tumor necrosis factor-α, IL-4, IL-1β, interferon-γ, and ET-1 in bronchoalveolar lavage fluid. In conclusion, the synthesis of ET-1 as measured by increased mRNA level precedes the synthesis of other proinflammatory cytokines of importance for the development of an eosinophilic airway inflammation, and ET antagonism inhibits the production of these mediators within the airways. Whether treatment with ET antagonists will prove beneficial for patients with eosinophilic airway inflammations like bronchial asthma is not yet known.

Résumé :

The spatiotemporal dynamics of inflammation provide vital insights into the understanding of skin inflammation. Skin inflammation primarily depends on the regulatory feedback between pro- and anti-inflammatory mediators. Healthy skin exhibits fading erythema. In contrast, diseased skin exhibits expanding erythema with diverse patterns, which are clinically classified into five types: circular, annular, arcuate, gyrate, and polycyclic. Inflammatory diseases with expanding erythema are speculated to result from the overproduction of pro-inflammatory mediators. However, the mechanism by which feedback selectively drives the transition from a healthy fading erythema to each of the five types of diseased expanding erythema remains unclear. This study theoretically elucidates the imbalanced production between pro- and anti-inflammatory mediators and prospective treatment strategies for each expanding pattern. Our literature survey showed that eleven diseases exhibit some of the five expanding erythema, thereby suggesting a common spatiotemporal regulation underlying different patterns and diseases. Accordingly, a reaction-diffusion model incorporating mediator feedback reproduced the five observed types of diseased expanding and healthy fading patterns. Importantly, the fading pattern transitioned to the arcuate, gyrate, and polycyclic patterns when the productions of anti-inflammatory and pro-inflammatory mediators were lower and higher, respectively than in the healthy condition. Further depletion of anti-inflammatory mediators caused a circular pattern, whereas further overproduction of pro-inflammatory mediators caused an annular pattern. Mechanistically, the bistability due to stabilization of the diseased state exhibits circular and annular patterns, whereas the excitability exhibits the gyrate, polycyclic, arcuate, and fading patterns as the threshold of pro-inflammatory mediator concentration relative to the healthy state increases. These dynamic regulations of diffusive mediator feedback provide effective treatment strategies for mediator production wherein skins recover from each expanding pattern toward a fading pattern. Thus, these strategies can estimate disease severity and risk based on erythema patterns, paving the way for developing noninvasive and personalized treatments for inflammatory skin diseases.

Résumé :

Abstract Epigallocatechin-3-gallate (EGCG), a bioactive component of green tea, has been reported to exert anti-inflammatory effects in immune cells. EGCG has been shown to activate the metabolic regulator, AMP-activated protein kinase (AMPK). Mesangial cells from MRL/lpr lupus-like mice are hyper-responsive to immune stimulation and overproduce nitric oxide (NO) and other inflammatory mediators when stimulated. In our current studies, we sought to determine if EGCG would inhibit inflammation in AMPK deficient mesangial cells. Cultured mesangial cells from MRL/lpr mice were treated with siRNA for mouse Prkaa2-Design A, specific for AMP-activated protein kinase-alpha (AMPK-α) or siRNA negative control for mouse. After 48 hours, the cells were serum-starved for 2 hours, treated with 50 μM epigallocatechin-gallate (EGCG) for one hour, and stimulated with lipopolysaccharide (LPS)/interferon (IFN)-γ for 30 minutes. The addition of siRNA inhibited AMPK expression in mesangial cells. LPS/IFN-γ induced inflammatory mediator production (iNOS expression, supernatant NO, and interleukin-6) as expected. Interestingly, EGCG blocked inflammatory mediator production in the AMPK deficient cells suggesting EGCG inhibits inflammatory pathways independently of AMPK to decrease inflammatory mediatory production. Taken together, these studies show that EGCG attenuated inflammation in MRL/lpr mouse mesangial cells independent of AMPK.

Résumé :

Characterization of the molecular response under caries lesions requires a robust and reliable transcript isolation system, and analysis of data indicated that collection of extracted teeth in either liquid nitrogen/RNA-stabilizing solution facilitated this. Subsequent transcriptional analysis indicated higher general activity in carious pulps, while characterization of inflammatory mediators, including cytokines and S100 proteins, highlighted increasing expression levels associated with both microbial front progression and elevated cellular immune response. Analysis of the pleiotropic hormone adrenomedullin (ADM) indicated that transcript and protein levels are increased in pulpal tissue during caries, and that protein levels sequestered in dentin due to primary dentinogenesis are comparable with those of TGF-β1. Expression analysis of a leucine-rich-repeat-containing protein (LRRC15/Lib) indicated that this highly conserved molecule was up-regulated during caries, is transcriptionally regulated by pro-inflammatory stimuli, and is relatively abundant in mineralized tissues.

Résumé :

During peritoneal dialysis, peritoneal cells are repeatedly exposed to a non-physiologic hypertonic environment with high glucose content and low pH. Current sterile dialysis solutions cause inflammation in the submesothelial compact zone, leading to fibrosis, angiogenesis, and, eventually, ultrafiltration failure. Although the normal interstitium separates the peritoneal microvasculature from the dialysis fluid and makes transperitoneal transport less efficient, changes in the submesothelial compact zone can result in progressive increases in solute transfer and ultrafiltration diminution. This peritoneal dysfunction will further be amplified with the development of an epithelial-to-mesenchymal transition of mesothelial cells and dissipation of the osmotic driving force through the increased area and solute transport that accompany neoangiogenesis of the submesothelial microvasculature. The alteration of the peritoneal membrane can be further aggravated by peritonitis, advanced glycation end-products, and glucose degradation products. Furthermore, new data are emerging to support a proinflammatory role for peritoneal adipocytes.

Résumé :

Lipid mediator informatics is an emerging area denoted to the identification of bioactive lipid mediators (LMs) and their biosynthetic profiles and pathways. LM informatics and proteomics applied to inflammation, systems tissues research provides a powerful means of uncovering key biomarkers for novel processes in health and disease. By incorporating them with system biology analysis, we review here our initial steps toward elucidating relationships among a range of bimolecular classes and provide an appreciation of their roles and activities in the pathophysiology of disease. LM informatics employing liquid chromatography-ultraviolet-tandem mass spectrometry (LC-UV-MS/MS), gas chromatography-mass spectrometry (GC-MS), computer-based automated systems equipped with databases and novel searching algorithms, and enzyme-linked immunosorbent assay (ELISA) to evaluate and profile temporal and spatial production of mediators combined with proteomics at defined points during experimental inflammation and its resolution enable us to identify novel mediators in resolution. The automated system including databases and searching algorithms is crucial for prompt and accurate analysis of these lipid mediators biosynthesized from precursor polyunsaturated fatty acids such as eicosanoids, resolvins, and neuroprotectins, which play key roles in human physiology and many prevalent diseases, especially those related to inflammation. This review presents detailed protocols used in our lab for LM informatics and proteomics using LC-UV-MS/MS, GC-MS, ELISA, novel databases and searching algorithms, and 2-dimensional gel electrophoresis and LC-nanospray-MS/MS peptide mapping.

Résumé :

Abstract The resolution of inflammation is an active and dynamic process. Newly identified lipid mediators have been recognized as key players during the process of inflammation resolution. These lipid-derived molecules constitute three classes of compounds (lipoxins, resolvins and protectins), all derived from essential fatty acids. New data demonstrates that these lipid mediators regulate aspects of the immune response, including inhibition of neutrophil infiltration, reduction of T cell cytokine production and stimulation of macrophage phagocytic activity. However, their effects on B lymphocytes are unknown. We show for the first time that the novel lipid mediator lipoxin B4 and 17-HDHA increase the ability of normal human B cells to produce IgM and IgG when activated with CpG plus anti-IgM. The two lipid derived molecules along with lipoxin A4 also enhance B cell differentiation, measured by an increased frequency of CD38+ cells. In addition, resolvin D1 and AT-resolvin also increase antibody production in CpG-stimulated B cells. None of the inflammation resolution lipid mediators affect proliferation and are non-toxic to the cells. Increase of plasma cell differentiation and antibody production coincides with the known involvement of pro-resolving mediators during the late stages of inflammation and pathogen clearance.

Résumé :

Lipid mediators are important regulators in inflammatory responses, and their biosynthetic pathways are targeted by commonly used anti-inflammatory drugs. Switching from pro-inflammatory lipid mediators (PIMs) to specialized pro-resolving (SPMs) is a critical step toward acute inflammation resolution and preventing chronic inflammation. Although the biosynthetic pathways and enzymes for PIMs and SPMs have now been largely identified, the actual transcriptional profiles underlying the immune cell type-specific transcriptional profiles of these mediators are still unknown. Using the Atlas of Inflammation Resolution, we created a large network of gene regulatory interactions linked to the biosynthesis of SPMs and PIMs. By mapping single-cell sequencing data, we identified cell type-specific gene regulatory networks of the lipid mediator biosynthesis. Using machine learning approaches combined with network features, we identified cell clusters of similar transcriptional regulation and demonstrated how specific immune cell activation affects PIM and SPM profiles. We found substantial differences in regulatory networks in related cells, accounting for network-based preprocessing in functional single-cell analyses. Our results not only provide further insight into the gene regulation of lipid mediators in the immune response but also shed light on the contribution of selected cell types in their biosynthesis.

Résumé :

AbstractOmega-3 polyunsaturated fatty acids (PUFAs), including eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, display a wide range of beneficial effects in humans and animals. Many of the biological functions of PUFAs are mediated via bioactive metabolites produced by fatty acid oxygenases such as cyclooxygenases, lipoxygenases and cytochrome P450 monooxygenases. Liquid chromatography–tandem mass spectrometry-based mediator lipidomics revealed a series of novel bioactive lipid mediators derived from omega-3 PUFAs. Here, we describe recent advances on omega-3 PUFA-derived mediators, mainly focusing on their enzymatic oxygenation pathway, and their biological functions in controlling inflammation and tissue homeostasis.

Résumé :

Background: Despite the advances of current optimal treatment of atherosclerotic disease, the incidence of events after acute coronary syndrome (ACS) remains high. Colchicine, with its well-established pleiotropic anti-inflam- matory effects, may inhibit NLRP3 inflammasome, a key mediator in atherosclerosis-associated inflammation (AAI) thus reducing systemic inflammation. NRLP3 inflammasome activation inside leukocytes (mainly monocytes and neutrophils) is precipitated by cholesterol crystals that are present in all atherosclerosis stages. 􏰟􏰋􏰡􏰈􏰇􏱎􏰋􏰇􏰆􏰂 􏰍􏰀􏰂􏰅􏰩􏰍􏰂􏰅􏰃􏰆 􏰃􏰜 􏰢􏰎􏰃􏰐􏰅􏰆􏰜􏰏􏰍􏰝􏰝􏰍􏰂􏰃􏰎􏰁 􏰀􏰁􏰂􏰃􏰄􏰅􏰆􏰇􏰈 􏰈􏰋􏰀􏰌 􏰍􏰈 􏰅􏰆􏰂􏰇􏰎􏰏􏰇􏰋􏰄􏰅􏰆􏰐􏰑􏰒 􏰍􏰆􏰗 􏰅􏰆􏰂􏰇􏰎􏰏􏰇􏰋􏰄􏰅􏰆􏰐􏰑􏰣 􏰳􏰅􏰏􏰏 􏰜􏰃􏰏􏰏􏰃􏰳􏰨 􏰘􏰌􏰇􏰈􏰇 cytokines are the crucial inflammatory pathway mediators that promote the formation of plaque and instability in the inflammatory cascade. Objective: This review will elaborate on the function of immune cells in atherosclerosis, explain the mechanisms of NLRP3 inflammasome activation in the context of AAI, and address the possible role of colchicine specifically targeting NLRP3 inflammasome and its concomitant downstream mediators in ACS, and provide an overview of current or ongoing studies produced in this area. Discussion : NRLP3 inflammasome activation inside leukocytes (mainly monocytes and neutrophils) is precipitat- ed by cholesterol crystals that are present in all atherosclerosis stages. Subsequent activation of pro-inflammatory pathway mediators that promote the formation of plaque and instability in the inflammatory cascade. A potential advantage of a medication acting through an inflammatory milieu found in atherosclerotic lesions has recently become the need for novel therapeutic options. Colchicine, with its well-established pleiotropic anti-inflammato- ry effects, may inhibit NLRP3 inflammasome, a key mediator in atherosclerosis-associated inflammation (AAI) thus reducing systemic inflammation. Conclusion: Colchicine is a safe and reliable medication for ACS patients, alongside reveal various benefit in reducing inflammation through inhibition of NLRP3 Inflammasome`

Résumé :

Controlled resolution or the physiologic resolution of a well-orchestrated inflammatory response at the tissue level is essential to return to homeostasis. A comprehensive understanding of the cellular and molecular events that control the termination of acute inflammation is needed in molecular terms given the widely held view that aberrant inflammation underlies many common diseases. This review focuses on recent advances in the understanding of the role of arachidonic acid and ω-3 polyunsaturated fatty acids (PUFA)–derived lipid mediators in regulating the resolution of inflammation. Using a functional lipidomic approach employing LC-MS-MS–based informatics, recent studies, reviewed herein, uncovered new families of local-acting chemical mediators actively biosynthesized during the resolution phase from the essential fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These new families of local chemical mediators are generated endogenously in exudates collected during the resolution phase, and were coined resolvins and protectins because specific members of these novel chemical families control both the duration and magnitude of inflammation in animal models of complex diseases. Recent advances on the biosynthesis, receptors, and actions of these novel anti-inflammatory and proresolving lipid mediators are reviewed with the aim to bring to attention the important role of specific lipid mediators as endogenous agonists in inflammation resolution.

Résumé :

Understanding of spatiotemporal profiling of inflammatory mediators and their associations with MΦ accumulation is crucial to elucidate the complex immune properties. Here, we used murine thioglycollate elicited peritonitis to determine concentrations of 23 inflammatory mediators in peritoneal exudates and plasma before (day 0) and after (days 1 and 3) thioglycollate administration to peritoneal cavities; these mediators included TNF-α, FGF-9, IFN-γ, IP-10, RANTES, IL-1α, IL-6, IL-7, IL-10, IL-11, IL-12p70, IL-17A, lymphotactin, OSM, KC/GRO, SCF, MIP-1β, MIP-2, TIMP-1, VEGF-A, MCP-1, MCP-3, and MCP-5. Our results showed that concentrations of most mediators in exudates and plasma reached peak levels on day 1 and were significantly reduced on day 3. Conversely, MΦnumbers started to increase on day 1 and reached peak levels on day 3. Moreover, LPS treatmentin vitrosignificantly induced mediator productions in cell culture media and lysates from MΦisolated on day 3. Our results also showed that on day 0, concentrations of many mediators in plasma were higher than those in exudates, whereas on day 1, the trend was reversed. Overall, the findings from thioglycollate elicited peritonitis reveal that reversible chemotactic gradients between peritoneal exudates and blood exist in basal and inflamed conditions and the inflammatory mediator productionin vivois disassociated with macrophage accumulation during inflammation resolution.

Résumé :

Inflammation-associated insulin resistance contributes to chronic disease in humans and other long-lived species, such as horses. Insulin resistance arises due to an imbalance among molecular signalling mediators in response to pro-inflammatory cytokines in the aged and obese. The mammalian heat shock protein response has received much attention as an avenue for attenuating inflammatory mediator signalling and for contributing to preservation and restoration of insulin signalling in metabolically important tissues. Data on heat shock proteins and inflammatory signalling mediators in untrained and aged horses are lacking, and horses represent an untapped resource for studying the mediator imbalance contributing to insulin resistance in a comparative model.

Résumé :

The interest in lipid mediators of inflammation as potential contributors to the pathogenesis of gastric ulcer has increased markedly over the past 20 yr. Although a great deal is known about the actions of mediators such as leukotrienes, thromboxane, and platelet-activating factor in experimental models of ulceration, evidence supporting a role for these mediators in human gastric ulcer is sorely lacking. This review attempts to answer a number of questions regarding the contribution of these mediators to the pathogenesis of gastric ulceration and the possible use of specific inhibitors, antagonists, and dietary manipulation in the treatment of gastric ulcer. Potential directions for future research in this field are suggested as are some of the pitfalls to be avoided in such studies.

Résumé :

Crohn's disease and ulcerative colitis are clinically, immunologically, and morphologically distinct forms of inflammatory bowel disease (IBD). However, smooth muscle function is impaired similarly in both diseases, resulting in diarrhea. We tested the hypothesis that differential cellular, genetic, and immunological mechanisms mediate smooth muscle dysfunction in two animal models believed to represent the two diseases. We used the rat models of trinitrobenzene sulfonic acid (TNBS)- and dextran sodium sulfate (DSS)-induced colonic inflammations, which closely mimic the clinical and morphological features of Crohn's disease and ulcerative colitis, respectively. DSS inflammation induced oxidative stress initially in mucosa/submucosa, which then propagated to the muscularis externa to impair smooth muscle function. The muscularis externa showed no increase of cytokines/chemokines. On the other hand, TNBS inflammation almost simultaneously induced oxidative stress, recruited or activated immune cells, and generated cytokines/chemokines in both mucosa/submucosa and muscularis externa. The generation of cytokines/chemokines did not correlate with the recruitment and activation of immune cells. Consequently, the impairment of smooth muscle function in DSS inflammation was primarily due to oxidative stress, whereas that in TNBS inflammation was due to both oxidative stress and proinflammatory cytokines. The impairment of smooth muscle function in DSS inflammation was due to suppression of Gαq protein of the excitation-contraction coupling. In TNBS inflammation, it was due to suppression of the α1C1b subunit of Cav1.2b channels, CPI-17 and Gαq. TNBS inflammation increased IGF-1 and TGF-β time dependently in the muscularis externa. IGF-1 induced smooth muscle hyperplasia; both IGF-1 and TGF-β induced hypertrophy. In conclusion, both TNBS and DSS induce transmural inflammation, albeit with different types of inflammatory mediators. The recruitment or activation of immune cells does not correlate directly with the intensity of generation of inflammatory mediators. The inflammatory mediators in TNBS and DSS inflammations target different genes to impair smooth muscle function.

Résumé :

Mast cells (MCs) and eosinophils (EOs) appeared hundreds of millions of years ago during the evolutionary process and continue to be retained by all vertebrate species. There is no convincing evidence of the absence of these cells in vertebrates under normal conditions. These cells are involved in the reactions of innate and adaptive immunity, in the control of tissue growth and tissue remodeling, activation of adipose tissue, affect reproductive functions and have a wide range of mediators involved in homeostasis. It is known that the interaction of these cells is involved in the initiation and maintenance of allergic inflammation. FcRI-mediated MC activation leads to mediators secretion, among which there are many chemotactic agents for EOs. These agents attract the EOs to the site of allergic inflammation. The EOs come into physical contact with the MCs, accompanied by the EO activation. As a result of the action of mediators released from MCs and EO, the active state of the cells is enhanced and maintained, and, accordingly, the process of inflammation is prolonged with the corresponding consequences in the form of triggering tissue remodeling. Eosinophil-derived active substances released during the reaction, having at least anti-mediator properties, contribute to the suppression and resolution of allergic inflammation. Such a look at the nature of the interactions between EOs and MCs justifies the comparative determination of the kinetics of the release of pro-allergic mediators from those cells and the formation of EO-derived compounds with antiallergic activity. It is expected that such studies will be carried out in the nearest future.

Résumé :

ABSTRACT Epidemiological studies have implicated periodontal disease (PD) as a risk factor for the development of cardiovascular disease (CVD). These studies addressed the premise that local infection may perturb the levels of systemic inflammatory mediators, thereby promoting mechanisms of atherosclerosis. Levels of inflammatory mediators in the sera of subjects with only PD, only CVD, both diseases, or neither condition were compared. Subjects were assessed for levels of C-reactive protein (CRP), serum amyloid A (SAA), ceruloplasmin, α1-acid-glycoprotein (AAG), α1-antichymotrypsin (ACT), and the soluble cellular adhesion molecules sICAM-1 and sVCAM by enzyme-linked immunoabsorbent and/or radial immunodiffusion assays. CRP levels in subjects with either condition alone were elevated twofold above subjects with neither disease, whereas a threefold increase was noted in subjects with both diseases (P = 0.0389). Statistically significant increases in SAA and ACT were noted in subjects with both conditions compared to those with one or neither condition (P = 0.0162 and 0.0408, respectively). Ceruloplasmin levels were increased in subjects with only CVD (P = 0.0001). Increases in sVCAM levels were noted in all subjects with CVD (P = 0.0054). No differences in sICAM levels were noted among subject groups. A trend toward higher levels of AAG was noted in subjects with both conditions and for ACT in subjects with only PD. Immunohistochemical examination of endarterectomy specimens of carotid arteries from subjects with atherosclerosis documented SAA and CRP deposition in association with atheromatous lesions. The data support the hypothesis that localized persistent infection may influence systemic levels of inflammatory mediators. Changes in inflammatory mediator levels potentially impact inflammation-associated atherosclerotic processes.

Résumé :

The presence of the so-called “low-grade” inflammatory state is recognized as a critical event in adipose tissue dysfunction in obesity. This chronic “low-grade” inflammation in white adipose tissue is powerfully augmented through the infiltration of macrophages, which, together with adipocytes, perpetuate a vicious cycle of macrophage recruitment and secretion of free fatty acids and deleterious adipokines that predispose the development of obesity-related comorbidities, such as insulin resistance and nonalcoholic fatty liver disease. In the last decade, many factors have been identified that contribute to mounting uncontrolled inflammation in obese adipose tissue. Among them, bioactive lipid mediators derived from the cyclooxygenase and 5-lipoxygenase pathways, which convert the ω-6-polyunsaturated fatty acid (PUFA) arachidonic acid into potent proinflammatory eicosanoids (i.e., prostaglandins [PGs] and leukotrienes), have emerged. Interestingly, the same lipid mediators that initially trigger the inflammatory response also signal the termination of inflammation by stimulating the biosynthesis of anti-inflammatory and proresolving lipid autacoids. This review discusses the current status, characteristics, and progress in this class of “stop signals”, including the lipoxins, which were the first identified ω-6 PUFA–derived lipid mediators with potent anti-inflammatory properties; the recently described ω-3 PUFA–derived lipid mediators resolvins and protectins; and the cyclopentenone PGs of the D series. Special emphasis is given to the participation of these bioactive lipid autacoids in the resolution of adipose tissue inflammation and in preventing the development of obesity-related complications.
