Book Synopsis Macrophages in inflammation and its resolution by : Heiko Mühl
Download or read book Macrophages in inflammation and its resolution written by Heiko Mühl and published by Frontiers E-books. This book was released on with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages were initially identified as a key element in the innate host response to infection and injury due to their phagocytic clearance and elimination of pathogenic and non-pathogenic entities. However, as macrophage research advanced it became clear that not only are these cells amenable to the acquisition of multiple plastic phenotypes during inflammatory responses to different pathogens, they also play a paramount role in the termination of inflammation and acquired immune responses. In addition, macrophages profoundly affect host physiology when they migrate to distant sites and differentiate to specialized cells, like foam cells, osteoclasts, adipose tissue- and tumor -associated macrophages and other macrophage-derived cell types. These processes are affected by the inflammation-resolution axis and can result in health threats, such as atherosclerosis, bone loss, obesity, fibrosis and cancer. This Research Topic issue will cover a wide range of topics in macrophage biology: 1. Macrophages in immune responses to pathogens 2. Macrophages in the termination of acute and acquired immunity. 3. The role of macrophages and their descendents in inflammation-associated pathologies. 4. Macrophage polarization and differentiation. Particular focus will be given to the modulation of macrophage phenotype and function following their encounter with apoptotic cells and the signaling cascades that govern these changes.

Book Synopsis Macrophages: Biology and Role in the Pathology of Diseases by : Subhra K. Biswas
Download or read book Macrophages: Biology and Role in the Pathology of Diseases written by Subhra K. Biswas and published by Springer. This book was released on 2014-11-12 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages are a key component of the innate immune system and play an integral role in host defense and homeostasis. On one hand, these cells contribute to host defence by triggering inflammation, displaying microbicidal/tumoricidal properties, regulating the activation of adaptive immunity and promoting resolution of inflammation. On the other hand, they contribute to essential trophic functions such as neural patterning, bone morphogenesis and ductal branching in mammary glands. Thus, macrophages are extremely versatile cells that can respond efficiently to tissue micro environmental cues by polarizing to distinct phenotypes, depending on the functions they need to perform. Indeed, functional diversity and plasticity are hallmarks of these cells. Macrophages may also play a detrimental role. An overwhelming body of literature has indicated their crucial role in pathogenesis. The list includes sepsis, cancer, metabolic syndrome, immunodeficiency, auto-immune disease-virtually impacting every major pathology that we know. These observations have suggested macrophages and their related molecules as potential targets in therapeutic applications. Available evidence proclaims macrophages as a key player in homeostasis, host defense and disease. Crucial developments in the past few years call for a re-evaluation and update of our understanding of macrophages. The present book is an endeavour that attempts provide state-of-the art knowledge of these cells in health and disease.

Book Synopsis Targeting Monocytes/Macrophages to Treat Atherosclerotic Inflammation by : Alessandro Corti
Download or read book Targeting Monocytes/Macrophages to Treat Atherosclerotic Inflammation written by Alessandro Corti and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is by now widely recognized that atherosclerosis - with its burden of consequences in cerebro- and cardiovascular diseases - is just a chronic inflammatory process of the arterial wall. A very peculiar, complex and as yet still poorly understood process, upon which hundreds of scientists from several different fields are continuously concentrating their investigative efforts in search of possible leads to therapeutic approaches. Initiation of the disease is given by deposition of lipid in the intimal layers, resulting in endothelial activation and infiltration of blood-derived mononuclear cells. These mature into macrophages, become activated, express scavenger receptors such as SR-A and CD36 and ingest the oxidized lipoprotein accumulating in the lesion. Macrophages thus represent an obvious target for intervention, as they play a crucial role in the progression of the atherosclerotic inflammation. Studies have shown that hypercholesterolaemia can increase monocyte mobilisation from bone marrow into the circulation, and several chemokines and their receptors are involved in the recruitment of blood borne monocytes into the arterial wall. Monocyte-derived macrophages are capable of sustaining their local proliferation, but resident macrophages possibly also participate in progression of the disease. Remarkably, smooth muscle cells can acquire macrophage-like features during atherogenesis, including the ability to uptake lipid, thus becoming a significant proportion of the CD68+ so called 'foam cells'. Lipid-laden macrophages induce extracellular matrix degradation, while lipid uptake eventually causes their death with formation of a necrotic core. The efficiency in clearance of dead cells by phagocytes (efferocytosis), can also be considered as a determinant of plaque vulnerability. An important feature of macrophages is their great plasticity and functional diversity in response to signals from the plaque microenvironment. Several such 'signals' (cholesterol, oxidative stress, hypoxia, cytokines...) can in fact modulate cell differentiation at transcriptional and epigenetic levels, thus altering the balance between the effector vs. reparative functions of macrophages. A whole gamut of specific subsets are thus originated, which appear to be simultaneously present in lesions with proportions that vary according to their location, the disease stage, and the presence of additional cell types such as e.g. dendritic cells. The result is a multiplicity of potential pharmacological targets, representing a major obstacle for the devisement of therapeutic strategies. Experimental approaches have been attempted in diverse directions: e.g. modulating the macrophage phenotype to an anti-inflammatory and resolving state, or blocking pro-inflammatory cytokines that macrophages produce, or alternatively enhancing efferocytosis in order to favour the resolution of inflammation and stabilization of plaques. Blocking monocyte recruitment was proposed in order to hinder the initial steps of atherogenesis. Other treatments were aimed to inhibiting local proliferation of pro-inflammatory macrophages. Specific targeting of macrophages has however to date not yet provided significant, translational results. The present Research Topic collects articles to help unravel the complexity of macrophage behaviour in atherosclerosis and identify innovative pharmacological approaches.
Book Synopsis Engineering the Knee Meniscus by : Kyriacos Athanasiou
Download or read book Engineering the Knee Meniscus written by Kyriacos Athanasiou and published by Springer Nature. This book was released on 2022-05-31 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The knee meniscus was once thought to be a vestigial tissue, but is now known to be instrumental in imparting stability, shock absorption, load transmission, and stress distribution within the knee joint. Unfortunately, most damage to the meniscus cannot be effectively healed by the body. Meniscus tissue engineering offers a possible solution to this problem by striving to create replacement tissue that may be implanted into a defect site. With a strong focus on structure-function relationships, this book details the essential anatomical, biochemical, and mechanical aspects of this versatile tissue and reviews current meniscus tissue engineering strategies and repair techniques. We have written this text such that undergraduate students, graduate students, and researchers will find it useful as a first foray into tissue engineering, a cohesive study of the meniscus, or a reference for meniscus engineering specifications.

Book Synopsis Skin and Arthropod Vectors by : Nathalie Boulanger
Download or read book Skin and Arthropod Vectors written by Nathalie Boulanger and published by Academic Press. This book was released on 2018-01-20 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent research on skin immunity and the skin microbiome reveals the complexity of the skin and its importance in the development of immunity against arthropod-borne diseases. In diseases such as malaria, borreliosis, leishmaniasis, trypanosomiasis, etc., the skin interface has been shown as an essential site for pathogens to hide from the immune system, and as a potential site of persistence. Only very few vaccines have been successfully developed so far against these diseases, likely because of an insufficient understanding on the development of skin immunity against pathogens. Skin and Arthropod Vectors expands our knowledge on the role of the skin interface during the transmission of arthropod-borne diseases and particularly its immunity. This work may support researchers who strive for developing more efficient diagnostic tools and vaccines. It also gives scientists and advanced students working in related areas a better insight on how humans and animals are attractive to arthropods to develop better repellents, or to set up transgenic arthropods. Offers the only compilation of research focusing on both the skin interface and arthropod vectors, with contributions from international experts Advances research in the effort toward generating more effective diagnostic tools and vaccines focusing on the skin interface Can also serve as supplemental material for dermatology lectures or specialized lectures on medical entomology and skin immunity
Book Synopsis Plasticity of monocytes/macrophages: phenotypic changes during disease progression by : Ruoxi Yuan
Download or read book Plasticity of monocytes/macrophages: phenotypic changes during disease progression written by Ruoxi Yuan and published by Frontiers Media SA. This book was released on 2023-12-07 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophage is a key component of innate immunity that exhibit extensive plasticity and heterogeneity. They are present in virtually every organ of the body and can be replenished by circulating monocytes following insults. Originally macrophages were divided into two major phenotypes: pro-inflammatory M1, which is initiated by TNF-α, INF-γ, and bacterial components such as lipopolysaccharide (LPS), and anti-inflammatory M2, which is activated through stimulation of IL-4, IL-10, and IL-13. However, segregation into two distinct phenotypes is a marked simplification of the in vivo reality and it is now widely accepted that macrophage phenotype is plastic and determined by highly complex microenvironments, and therefore likely more accurately considered as a spectrum of possible forms of activation. Numerous studies have documented flexibility in their programming, with macrophages switching from one functional phenotype to another in response to the variable microenvironmental signals of the local milieu. Various macrophage populations exist that play distinct and non-redundant roles in fibrosis, tissue repair, and regeneration. For instance, in a general wound healing process, embryo-derived tissue-resident macrophages are rapidly replaced by monocytes after the initial injury. These monocyte-derived macrophages play an active role in the early initiation of acute inflammation. As early as 24–72 h upon tissue injury, macrophage function changes toward an anti-inflammatory phenotype that promotes cell proliferation and tissue remodeling. Upon resolution of inflammation, steady-state self-maintenance of macrophages is also recovered. The wound microenvironment has a predominant role in the behavior and functionality of cells. Both mouse and human diabetic wound preferably induce persistent proinflammatory macrophage polarization that contributes to chronic, non-healing wounds. Contrastingly, prolonged activation of M2 macrophages can also lead to excessive wound healing and ultimately fibrosis. In the context of cancer, anti-inflammatory macrophages have been associated with tumor progression and immunosuppression, thereby negatively affecting the prognosis of patients. On the other hand, studies also showed that the phenotypical changes of macrophages are also accompanied by changes in glycolysis and mitochondrial-related genes as well. Classically activated, proinflammatory M1 macrophages depend to a large extent on glycolysis and produce lactate as the tricarboxylic acid cycle is blocked at two steps. Alternatively, activated M2 macrophages prefer β-oxidation and oxidative phosphorylation to synthesize ATP. However, the number and diversity of signals and the magnitude of the response required to switch macrophages into a pro or anti-inflammatory state remain unclear. A number of techniques have been developed over the years to identify and visualize cell populations, uncover regulatory relationships between genes, and track the trajectories of distinct cell lineages in development. The identification of mechanisms and molecules associated with macrophage plasticity and polarized activation provides a basis for macrophage-centered diagnostic and therapeutic strategies. Understanding and being able to controllable promote the desired macrophage phenotypes could have a significant impact on a wide range of diseases.
Book Synopsis Regulation of Inflammation, Its Resolution and Therapeutic Targeting by : Mariagrazia Uguccioni
Download or read book Regulation of Inflammation, Its Resolution and Therapeutic Targeting written by Mariagrazia Uguccioni and published by Frontiers Media SA. This book was released on 2018-01-11 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflammation is a fundamental protective mechanism and at the same time the driving force of a variety of major diseases in humans. Indeed, acute self-resolving inflammation usually plays a positive role for the host, as exemplified by infectious diseases where its positive role is well established and testified by its perception as innate immunity. On the other hand, non-resolving inflammation and consequent chronicization is a key determinant of immunopathology and clinical manifestations of most major diseases in humans. As a consequence, it is increasing appreciated that the problem with inflammation is not how often it starts, but how often it fails to resolve. Appropriate resolution of inflammatory responses, which also drives activation of tissue damage repair mechanisms and return of local tissues to homeostasis, is a necessary process for ongoing health. Interestingly, cells sustaining these processes are also key to the proinflammatory responses, and the underlying “pro-resolving” molecular pathways are triggered as part of the pro-inflammatory response. This clearly indicates resolution of inflammation as an active process requiring functional repolarization of inflammatory cells that calls our attention on the underlying molecular mechanisms. The increasing number of anti-inflammatory drugs best-sellers in the pharma market is a clear indication of the relevance of having inflammation under check; nonetheless, there is still a great need for better acting pharmacological tools for the control of inflammation. Indeed, the remarkable success of biological drugs targeting proinflammatory cytokines has indicates that tools able to block proinflammatory mediators have promising applications, but at the same time has made clear that there are intrinsic limitations to this approach which frequently vanish undermine the activity of single targeting drugs, including the well-known redundancy of inflammatory mediators. Under self-limiting conditions inflammation spontaneously resolves in an active process. Some cellular and molecular mechanisms involved in inflammation resolution have been uncovered in the recent past, and include generation of specific cytokines, apoptosis of inflammatory leukocytes, lipid mediators, macrophage repolarization and others are likely to be revealed in the next future, since loss-of-function mutations of an increasing number of genes results in the development of spontaneous inflammation in experimental animals. We argue that “pushing for“ inflammation resolution by exploiting active naturally-occurring pro-resolving processes may have significant advantages over the attempt to simply “push back” inflammation by passive blockade of proinflammatory mediators. At present the research in the field of inflammation aims at identifying and validates new molecules involved in the resolution of inflammation as a basis for the development of innovative therapeutic strategies in chronic inflammatory and autoimmune diseases. This involves the discovery of new natural or synthetic “pro-resolving” molecules from plant and animals and the investigation of endogenous inflammation “pro-resolving” mechanisms, including atypical chemokine receptors, decoy receptors, and microRNA. An extensive effort is focused on the regulation by “pro-resolving” agents on two molecular systems of key relevance in inflammation: the chemokine system, which regulates recruitment, permanence and egress of leukocyte in tissues; and the Toll Like Receptor (TLR)/IL-1R system, which is central for the activation of infiltrating leukocytes.
