Download or read book Immunobiology of the Macrophage written by David S. Nelson and published by Academic Press. This book was released on 2014-06-28 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunobiology of the Macrophage presents an account of the state of knowledge of the immunobiology of the macrophage. The book’s contributors—immunologists of diverse scientific and geographic backgrounds—have been encouraged to give personal accounts of developments in their special fields of interest as well as critical surveys of the backgrounds leading to these developments. The book begins with a study on the functions of macrophages in the initiation and regulation of antibody responses in vitro. This is followed by separate chapters on topics such as the role of macrophages in making antigen more immunogenic and less tolerogenic; functional distinctions between macrophages at different sites; and the role of the macrophage in antigen recognition by T lymphocytes. Subsequent chapters examine interactions between macrophages and lymphocytes in the production of interferon and other mediators of cellular immunity; macrophage cell lines and their uses in immunobiology; and cytotoxic macrophages in allograft rejection.

Available in PDF, EPUB and Kindle. Book excerpt: Historically the study of the immune system and metabolism have been two very separate fields. In recent years, a growing literature has emerged illustrating how the multiple processes of cellular metabolism are intricately linked to several aspects of immune function and development. This Research Topic covers recent progress in the field now known as “Immunometabolism” and the role of metabolism in immune tolerance. Immune tolerance is operationally defined as a state where a host’s immune system is balanced such that although self-reactive lymphocytes are present, they are kept in check by immune regulation. Perturbations to this homeostasis may result in self-reactive lymphocytes gaining the upper hand and mediating auto-immune disease. Maintenance of immune tolerance involves a large cast of different cell types including effector T cells, regulatory T cells, B cells, stromal cells, dendritic cells and macrophages. Intracellular pathways and individual enzymes of metabolism have been shown to be harnessed by cells of both the adaptive and innate immune system to allow particular immune functions to be achieved. Examples include metabolic enzymes serving ‘moonlighting’ functions in mRNA translation, gene splicing, and kinase activation. Other examples include the requirement for de novo fatty acid synthesis for differentiation into Th17 effectors and CD8 memory T cells or products of the TCA cycle promoting pro-inflammatory cytokine production. Likewise, the availability of extracellular metabolic substrates has a large impact on the maintenance of local immune tolerance. For example, there are different requirements for glucose, glutamine and fatty acids for effector versus regulatory T cell development. Also tolerogenic dendritic cells mediate lowering of extracellular essential amino acids by their enhanced catabolism, promoting the induction of regulatory T cells. The purpose of this Research Topic is to provide an update on the current understanding of the multiple roles for metabolism in regulating the immune system.
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.
Download or read book Immune regulation at the fetal maternal interface with focus on decidual macrophages written by Judit Svensson?Arvelund and published by Linköping University Electronic Press. This book was released on 2015-04-21 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: A successful pregnancy requires that the maternal immune system adapts to tolerate the semi-allogeneic fetal-placental unit. This adaptation mainly occurs locally, i.e. at the fetal-maternal interface, where fetal-derived tissues come into close contact with maternal cells in the uterine endometrium (called decidua during pregnancy). Macrophages and regulatory T (Treg) cells are maternal immune cells that are enriched in the decidua and they likely play a central role in promoting fetal tolerance. However, the precise function of decidual macrophages and the factors regulating both macrophages and Treg cells in humans are unknown. The aim of this thesis was to characterize the phenotype and function of decidual macrophages from first trimester human pregnancy and to identify factors responsible for inducing tolerogenic properties in both decidual macrophages and Treg cells. CD14+ decidual macrophages showed characteristics of immune suppressive or homeostatic macrophages (expression of CD163, CD206 and CD209), mainly produced immunosuppressive cytokines, like IL-10 and IL-35, while levels of inflammatory cytokines, for instance IL-12 and IL-23, were low. Decidual macrophages also induced the expansion of CD25highFoxp3+ Treg cells, but not of Th1, Th2 and Th17 cells, in vitro. In addition, decidual macrophages preferentially secreted the monocyte- and Treg cell-associated chemokines CCL2 and CCL18, while Th1-, Th2- and Th17-related chemokines were produced at low levels. These results suggest that decidual macrophages contribute to create the unique decidual cell composition and a tolerogenic immune environment that is compatible with fetal development. Further, by comparing decidual macrophages with different in vitro macrophage subsets, we showed that M-CSF and IL-10, but not GM-CSF, Th1 or Th2 stimuli, induced macrophages that resemble decidual macrophages in terms of cell surface marker expression, cytokine andchemokine production and gene expression profile. First trimester placental tissue, in particular placental trophoblast cells, was identified as an important source of M-CSF and IL-10. We also demonstrated that human fetal-derived placental tissue can induce the characteristics of decidual macrophages (CD163+CD206+CD209+IL-10+CCL18+) and the selective expansion of functionally suppressive CD25highFoxp3+ Treg cells, the latter partly mediated through IL-10, TGF-? and TRAIL. The placenta also limited activation of Th cells, for instance by generally reduced cytokine production. Our data show that the placenta has a unique ability to induce tolerogenic immune cells with a reduced inflammatory potential, which is essential for maintaining tissue integrity and preventing inflammation-induced fetal loss.

Available in PDF, EPUB and Kindle. Book excerpt: Immunological Tolerance: A Reassessment of Mechanisms of the Immune Response presents the basic biological phenomena of immunological tolerance. This book discusses immunology as a critical field for the analysis of molecular features of mammalian cell genetics, biosynthesis, differentiation, and interactions among cell types. Organized into six chapters, this book begins with an overview of the relationship between antigen structure and its ability to induce tolerance. This text then examines the essentiality of antigen for the proliferation of activated antibody-forming clones and discusses the role of antibody in homeostasis and suppression. Other chapters consider the restoration and transfer of immunological responsiveness by thoracic duct lymphocytes. This book discusses as well the distribution of antigen in tissues and cells. The final chapter deals with the origin of carrier antibody and the significance of maternal transfer of antibodies and antigens. This book is a valuable resource for immunologists, microbiologists, scientists, and clinicians.

Available in PDF, EPUB and Kindle. Book excerpt: Immunological Tolerance: Mechanisms and Potential Therapeutic Applications documents the proceedings of a conference held at Brook Lodge, Michigan, April 27-May 1, 1974. The conference brought together many of the investigators who have actively contributed to furthering knowledge and understanding of immunological tolerance. It will be immediately clear to the reader that the conference was structured in a way to consider phenomena of tolerance and immune suppression as interrelated entities with a certain degree of emphasis on the possible common cellular mechanisms involved. The volume contains 36 contributions presented during the seven sessions of the conference. The papers presented in Session I examined T-cell tolerance. The presentations in Session II focused on B cell tolerance. The papers in Sessions III and IV focused on the mechanisms of B cell and T cell tolerance, respectively. Session V dealt with the activity of suppressor cells as a mechanism of tolerance. The papers in Session VI investigated the suppressive activity of antibody and antigen-antibody complexes. In Session VII a final General Discussion was held in order to identify what has been established concerning the phenomenology and mechanisms of specific immunological tolerance, what are the major unresolved issues, and what approaches appear most promising to answer these questions.

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.
