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 microenvironmental 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 to provide state-of-the art knowledge of these cells in health and disease.

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.

Featuring contributions from eminent immunologists, microbial geneticists, and cell and molecular biologists, this single volume brings together a current understanding of how phagocytes recognize and respond to potentially pathogenic microbes. It explores and explains the complex biology underlying the different phagocyte lineages that enables them to sense and respond to their environments.

Macrophages are tissue resident phagocytes that have important roles in development and immunity. The observation that cancers become infiltrated by large numbers of macrophages was first made by Virchow in 1863, clinical and experimental studies suggest tumor-associated macrophages (TAM) are critical to promote carcinogenesis and tumor-progression, however to this day it still isn’t clear what regulates the recruitment of macrophages in tumors and what drives their pro-tumor functions. This volume will provide an overview of current research on the form and function of TAM, highlighting both the mechanistic roles they play in carcinogenesis and tumor progression as well as the molecular mechanisms that control their phenotype and function, and the final chapter addresses the issue of TAM as a potential target in cancer therapy.
