Available in PDF, EPUB and Kindle. Book excerpt: Neutrophils play a central role in host defense against infection and tissue injury. PMNs integrate opposing cues within the inflammatory microenvironment, which converge on selected receptors. Among these receptors is the pleiotropic receptor, formyl peptide receptor 2/lipoxin receptor (FPR2/ALX), which can recognize over 20 structurally diverse proteins, peptides, and lipid ligands. Among these ligands are N-formylated peptides released from mitochondria of dying or dead host cells. At present, little is known about the molecular basis for how FPR2/ALX integrates opposing cues and triggers diverse biological responses. We wanted to test the effect of N-formylated peptides on human neutrophils' functions in sepsis-like syndrome. We found that the pleiotropic receptor FPR2/ALX integrates opposing signals that govern phagocytosis, bacterial killing, the fate of neutrophils, and ultimately the outcome of the inflammatory response. This action of N-formylated peptides is mediated through induction of the release of neutrophil elastase from the primary granules and subsequent downregulation of complement C5a receptor on the cell surface. This effect can be reversed by pro-resolving lipid mediators, aspirin-triggered 15-epi-lipoxin A4 (15-epi-LXA4) and 17-epi-resolvin D1 (17-epi-RvD1). Our results could lead to the development of novel pharmacological strategies to enhance FPR2/ALX-mediated protective mechanisms that may limit the inflammatory response and promote the resolution of inflammation.
Download or read book Resolution Pharmacology Innovative Therapeutic Approaches Based on the Biology of Resolution to Control Chronic Diseases of Western Societies written by Mauro Perretti and published by Frontiers Media SA. This book was released on 2019-11-04 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this eBook, we have grouped together 16 original contributions which have addressed the translational potential for therapeutics developed on the conceptual framework of the resolution of inflammation. The take home message of our effort, and the efforts of our colleagues who wrote these pieces, is that completely different drugs can be designed and modelled on the mediators and targets of resolution. By implementing this 180° shift in the way we plan the drug development programme (that is by focusing on agonists and/or promoting the actions of pro-resolution agonists) we can offer a fresh approach to the clinical management of chronic diseases that affect the modern society. With this series of articles we foresee the birth of Resolution Pharmacology. The 16 contributions presented herein confirm the broad relevance of pro-resolving physio-pharmacology with the description of pro-resolving mechanisms in distinct diseases, from atherosclerosis and heart infarct, to cystic fibrosis and diabetes. This testifies on one hand the fundamental role that inflammatory mechanisms play in virtually all pathological settings and, on the other hand, the great potential that a novel approach to anti-inflammatory therapy by exploiting resolution mediators and targets may have. Thus, while there is broad recognition that evidence-based interventions have transformed cardiovascular, inflammation and endocrine care, new therapies are still needed for growing numbers of patients with unmet needs. As an example, an estimated 17 million people world-wide die annually of cardiovascular diseases, particularly heart attacks and strokes. Cardiovascular diseases occur almost equally in men and women and are the leading cause of death and morbidity worldwide. It is estimated that only 1/1,000 compounds entering preclinical testing are then trialled in man and the actual cost of developing a new therapeutic into clinical practice has grown exponentially over the past two decades (estimated $1.2B). Over the last 20 years or more, scientists have appreciated the biology of the resolution of inflammation, which provides a new paradigm in our understanding of the inflammatory process with the appreciation of genetic, molecular and cellular mechanisms that are engaged to actively resolve inflammation. The ‘resolution of acute inflammation’ is enabled by counter-regulatory checkpoints to terminate the host reaction while at the same time promoting healing and repair. The potential of lipid mediators to enact pro-resolving effects in the context of cystic fibrosis is presented by Recchiuti et al., while Fredman reasons on the potential for these molecules in atherosclerosis. This resonates well with the contributions from Bäck and colleagues who have focused on pro-resolving receptors to offer vasculo-protection in intimal hyperplasia and more generally in cardiovascular disease. On the same vein is the scholar contribution of Leoni and Soehnlein who focus on heart disease, with Qin et al. presenting the latest findings on the effect of an Annexin A1-derived peptide in myocardial infarction. Hansen et al. and de Gaetano et al. bring in the complexity of diabetes and associated morbidity with a focus on specialised pro-resolving lipid mediators but also introducing the potential of dietary approaches. As the western diet favours disease, an omega-3 rich diet can lead to higher availability of lipid mediators to afford tissue protection if not reverting its pathological status. Docosahexaenoic acid and its bioactive derivatives are endowed with potent anti-nociceptive properties following bone fracture, as shown by Zhang et al. The broad relevance of the pharmacological approach reaches the skin with Resolvin D1 protecting against UV irradiation (Saito et al.). Reduced skin inflammation is also achieved with an Annexin A1 peptide that impacts on the outcome of heterologous transplantation (Lacerda et al.). Indeed, modulating the phenotype of immune cells can provide long lasting beneficial outcomes, as attained with CDK inhibitors (Cartwright et al.) and PI3K inhibitors in experimental gout (Galvao et al.). Such an effect is also achieved with a third group of pro-resolving therapeutics, the melanocortin receptor agonists, with important modulation of macrophage reactivity (Patruno et al.) with Spana et al., providing new pharmacology following selective activation of the MC1 receptor. Finally, Hopkin et al. discuss the potential for targeting immune cell trafficking as a way to control immune mediated diseases, bringing in not only pro-resolving mediator agonists, but also approaches to reduce chemo/cytokine gradients or modulating S1P and 11-beta hydroxysteroid dehydrogenase. Finally, we wish to highlight that this wealth of science has also bought to the forefront specific pro-resolving receptors (including FPR2/ALX, GPR32, ChemR23 and MC1), all G protein coupled receptors that are therefore amenable to pharmacological exploitation for drug discovery programmes. We see that not only agonists to the receptors can be developed, some of them modelled on the natural ligands (e.g. resolvins, lipoxins, Annexin A1-derived peptides or melanocortin peptides), but also that the creativity of this pharmacology can be attained through biased ligands and positive allosteric modulators. Deep knowledge of pro-resolving receptor biology and their cell-specific signalling can accelerate the generation of novel anti-inflammatory depicted on the resolution of inflammation. In conclusion, with this eBook, we propose time is ready to exploit the concepts of resolution and use its targets and mediators for the identification of better drugs to establish ‘Resolution Pharmacology’. We predict Resolution Pharmacology will represent an important innovation in the way common diseases will be treated in the next decades of this millennium.

Download or read book The Molecular Mechanisms of Chronic Inflammation Development written by Masaaki Murakami and published by Frontiers E-books. This book was released on with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflammation is critical for the development of many complex diseases and disorders including autoimmune diseases, metabolic syndrome, neurodegenerative diseases, cancers, and cardiovascular diseases. Inflammation comes as two types: chronic inflammation, which can be defined as a dysregulated form of inflammation, and acute inflammation, which can defined as a regulated form. Because of its special role in the aforementioned diseases, establishing methods to control chronic inflammation is important for developing cures and treatments. One challenge for this purpose has been the ability to distinguish chronic and acute inflammation based on molecular biology diagnostics. Thus, this Research Topic is focused on articles that can shed some new light on the molecular mechanisms responsible for the development of chronic inflammation and its related conditions.

Download or read book Neurobiology of Chemical Communication written by Carla Mucignat-Caretta and published by CRC Press. This book was released on 2014-02-14 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Download or read book Molecular Basis of Health and Disease written by Undurti N. Das and published by Springer Science & Business Media. This book was released on 2011-04-02 with total page 591 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes how the balance between pro- and anti-inflammatory molecules is related to health and disease. It is suggested that many diseases are initiated and their progress is influenced by inflammatory molecules and a decrease in the production and/or action of anti-inflammatory molecules and this imbalance between pro- and anti-inflammatory molecules seems to have been initiated in the perinatal period. This implies that strategies to prevent and manage various adult diseases should start in the perinatal period. An alteration in the metaolism of essential fatty acids and their anti-inflammatory molecules such as lipoxins, resolvins, protecitns, maresins and nitrolipids seems to play a major role in the pathobiology of several adult diseases. Based on these concepts, novel therapeutic approaches in the management of insulin resistance, obesity, type 2 diabetes mellitus, metabolic syndrome, cancer, lupus, rheumatoid arthritis and other auto-immune diseases are presented. Based on all these evidences, a unified concept that several adult diseases are due to an alteration in the balance between pro- and anti-inflammatory molecules is discussed and novel methods of their management are presented.
