Macrophages Biology And Tissue Inflammation In Health And Disease

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.

One, No one, One Hundred Thousand - The Multifaceted Role of Macrophages in Health and Disease - Part A, provides in-depth reviews on the last progresses on the role of macrophages in health and diseases with a special focus on the role of macrophages in SARS-COV2, breast cancer, liver and salivary glands. Provides accurate reviews from selected experts on the topic of macrophages in different tissues such as lung, uterus, breast and liver Each chapter of the volume provides useful graphic material for ease of reading of the audience Provides the latest insights and future perspectives on macrophage heterogeneity in different diseases

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.

The type 2 immune response that develops during infectious disease has undergone major paradigm shifts in the last several years as new cell types and pathways have been identified. It is now clear that the type 2 immune response, characterized by elevations in specific cytokines, including IL-4, IL-5 and IL-13, is associated with helminth infections in both humans and mice. This response is complex and includes effector functions that mediate resistance, contributing to expulsion and in some cases destruction, of the parasite. But just as importantly, the type 2 immune response can also mediate tolerance mechanisms, which can mitigate tissue injury as these large multicellular parasites transit through vital organs. The tolerance mechanisms include both tissue repair and immune regulatory effects. These latter aspects of the helminth-induced type 2 immune response are increasingly recognized as a potential resource that can be mined for the development of novel immunotherapies that may enhance wound healing, control of autoimmune and inflammatory diseases and regulation of metabolic homeostasis. In this book, leading researchers in this exciting and dynamic field discuss the latest findings and emerging concepts, providing an intellectual framework that can be used as a basis for new discoveries and potentially new treatments for diseases associated with inflammation.

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.
