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.

Download or read book Lung Inflammation written by Kian Chung Ong and published by BoD – Books on Demand. This book was released on 2014-05-14 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to perform its function in gas exchange, the lungs and all components of the respiratory system are constantly exposed to pathogens, toxins, pollutants, irritants, and allergens in the environment. Lung inflammation involves an array of mechanisms to defend the lung against these extrinsic agents and to repair injured tissue. Additionally, the lungs are a frequent target at risk to conditions associated with systemic inflammation that cause multi-organ damage. The inflammatory reaction in the lung is a complex and dynamic process, and our understanding in this field is rapidly progressing. Further elucidation of the complexity of inflammation will likely improve the clinicians approach to as well as the treatment of a myriad of lung disorders. The chapters in this book are selected topics of current interest in lung inflammation.

Download or read book The M2 Macrophage written by Tamás Röszer and published by Springer Nature. This book was released on 2020-08-03 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages are core components of the innate immune system. Once activated, they may have either pro- or anti-inflammatory effects that include pathogen killing, safe disposal of apoptotic cells or tissue renewal. The activation state of macrophages is conceptualized by the so-called M1/M2 model of polarization. M2 macrophages are not simply antagonists of M1 macrophages; rather, they represent a network of tissue resident macrophages with roles in tissue development and organ homeostasis. M2 macrophages govern functions at the interfaces of immunity, tissue development and turnover, metabolism, and endocrine signaling. Dysfunction in M2 macrophages can ruin the healthy interplay between the immune system and metabolic processes, and lead to diseases such as insulin resistance, metabolic syndrome, and type 1 and 2 diabetes mellitus. Furthermore, M2 macrophages are essential for healthy tissue development and immunological self-tolerance. Worryingly, these functions of M2 macrophages can also be disrupted, resulting in tumor growth and autoimmunity. This book comprehensively discusses the biology of M2 macrophages, summarizes the current state of knowledge, and highlights key questions that remain unanswered.

Available in PDF, EPUB and Kindle. Book excerpt: Macrophages are the sentinels of the immune system whose role has evolved beyond providing aseptic conditions to homeostasis, immune regulation, development, and behaviour. These cells have varied ontogenetic origins which reflects in their phenotypic and functional heterogeneity. Macrophage functions are fine-tuned by exogenous and endogenous signals and once tweaked, the information is included in their genetic makeup, albeit not indefinitely. Subversion of the macrophage functions is the hallmark of many pathogenic organisms and modulation of macrophage activity is pivotal to many therapeutic strategies. Fascinating and rapid developments in this field have necessitated the maintenance of currency of knowledge. This book provides a current account of information on varied topics in macrophage biology. Literature surveys have been presented in a captivating and lucid language. The contributing authors have also provided brief accounts of their own research. Every chapter provides a future perspective of what more could be achieved in the context of the current knowledge. The book will be of interest to students and researchers in microbiology, immunobiology, translational research, pathology, and related fields.

Download or read book M1 M2 Macrophages The Arginine Fork in the Road to Health and Disease written by Charles Dudley Mills and published by Frontiers Media SA. This book was released on 2015-03-23 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages have unique and diverse functions necessary for survival. And, in humans (and other species), they are the most abundant leukocytes in tissues. The Innate functions of macrophages that are best known are their unusual ability to either “Kill” or “Repair”. Since killing is a destructive process and repair is a constructive process, it was stupefying how one cell could exhibit these 2 polar – opposite functions. However, in the late 1980’s, it was shown that macrophages have a unique ability to enzymatically metabolize Arginine to Nitric Oxide (NO, a gaseous non – specific killer molecule) or to Ornithine (a precursor of polyamines and collagen for repair). The dual Arginine metabolic capacity of macrophages provided a functional explanation for their ability to kill or repair. Macrophages predominantly producing NO are called M1 and those producing Ornithine are called M2. M1 and M2 – dominant responses occur in lower vertebrates, and in T cell deficient vertebrates being directly driven by Damage and Pathogen Associated Molecular Patterns (DAMP and PAMP). Thus, M1 and M2 are Innate responses that protect the host without Adaptive Immunity. In turn, M1/M2 is supplanting previous models in which T cells were necessary to “activate” or “alternatively activate” macrophages (the Th1/Th2 paradigm). M1 and M2 macrophages were named such because of the additional key findings that these macrophages stimulate Th1 and Th2 – like responses, respectively. So, in addition to their unique ability to kill or repair, macrophages also govern Adaptive Immunity. All of the foregoing would be less important if M1 or M2 – dominant responses were not observed in disease. But, they are. The best example to date is the predominance of M2 macrophages in human tumors where they act like wound repair macrophages and actively promote growth. More generally, humans have become M2 – dominant because sanitation, antibiotics and vaccines have lessened M1 responses. And, M2 dominance seems the cause of ever - increasing allergies in developed countries. Obesity represents a new and different circumstance. Surfeit energy (e.g., lipoproteins) causes monocytes to become M1 dominant in the vessel walls causing plaques. Because M1 or M2 dominant responses are clearly causative in many modern diseases, there is great potential in developing the means to selectively stimulate (or inhibit) either M1 or M2 responses to kill or repair, or to stimulate Th1 or Th2 responses, depending on the circumstance. The contributions here are meant to describe diseases of M1 or M2 dominance, and promising new methodologies to modulate the fungible metabolic machinery of macrophages for better health.

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.

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.
