Book excerpt: Phagocytosis—Past and Future is a collection of contributions by investigators who met in the Province of Messina, Sicily, in October 1980 to discuss the functions of phagocytic leukocytes in the host-parasite relationship. The topics discussed are largely in the areas of cell biology, cellular immunology, and biochemistry. They ranged from aspects of cellular movement and the ingestion process per se, to definition of substances that affect the function of phagocytic leukocytes and the nature of cidal mechanisms at the molecular level. This volume is organized into six sections encompassing 33 chapters and begins with an overview of Ilya Ilich Metchnikoff's life as well as his scientific contributions, particularly in the area of bacteriology and his research on mesodermal amoeboid cells. The next chapters focus on the mechanism of phagocytosis, with reference to aspects of cell membrane, cell movement, and ingestion. The reader is methodically introduced to the biochemical aspects of phagocytosis, from molecular modulations to energetics, oxygen radicals, and enzymes. The discussion then shifts to macrophages, their function in antigen recognition, receptor-mediated endocytosis in macrophage cell hybrids, and the role of phagocytosis in macrophage activation. The remaining chapters examine the cidal mechanisms of phagocytic leukocytes and aspects of inflammation. This book will be of interest to scientists and researchers in fields such as biology, biochemistry, immunology, pathology, pharmacology, and physiology.

Download or read book Molecular and Cellular Biology of Phagocytosis written by Maurice B. Hallett and published by Springer Nature. This book was released on 2020-05-12 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phagocytosis is the engulfment of particulate matter by cells. It is a fundamental (and probably “primitive”) cell biological process which is important in single celled organisms such as amoeba; multicellular animals including coelenterates; and in higher animals. In humans and other mammals, specialised immune cells (phagocytes) utilise phagocytosis in their crucial role of engulfing and destroying infecting microbes. Yet, surprisingly, the biophysics and biochemistry underlying the process has only become clear recently with the advent of genetic manipulation and advances in single cell imaging. In this volume, the aim is to bring together recent fundamental advances that give a clear picture of the underlying mechanism involved in phagocytosis. Not only is this an important topic in its own right, but a full understanding of the process will have a potential impact on human medicine, since as antibiotics become less effective in fight infection, researchers are looking at alternative approaches, including enhancing the “natural” immunity brought about by immune phagocytes. The aim is to provide a comprehensive volume on the topic, with separate chapters on identified recent advances, each written by the major contributors in each area. In addition, the volume will attempt to give a wider overview than is often the case in single author reviews, with an emphasis here on the cell biological understanding of phagocytosis using biophysical approaches alongside the biochemical and imaging approaches.
Download or read book Antibody Fc written by Margaret Ackerman and published by Academic Press. This book was released on 2013-08-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibody Fc is the first single text to synthesize the literature on the mechanisms underlying the dramatic variability of antibodies to influence the immune response. The book demonstrates the importance of the Fc domain, including protective mechanisms, effector cell types, genetic data, and variability in Fc domain function. This volume is a critical single-source reference for researchers in vaccine discovery, immunologists, microbiologists, oncologists and protein engineers as well as graduate students in immunology and vaccinology. Antibodies represent the correlate of protection for numerous vaccines and are the most rapidly growing class of drugs, with applications ranging from cancer and infectious disease to autoimmunity. Researchers have long understood the variable domain of antibodies, which are responsible for antigen recognition, and can provide protection by blocking the function of their target antigen. However, recent developments in our understanding of the protection mediated by antibodies have highlighted the critical nature of the antibody constant, or Fc domain, in the biological activity of antibodies. The Fc domain allows antibodies to link the adaptive and innate immune systems, providing specificity to a wide range of innate effector cells. In addition, they provide a feedback loop to regulate the character of the immune response via interactions with B cells and antigen-presenting cells. - Clarifies the different mechanisms of IgG activity at the level of the different model systems used, including human genetic, mouse, and in vitro - Covers the role of antibodies in cancer, infectious disease, and autoimmunity and in the setting of monoclonal antibody therapy as well as naturally raised antibodies - Color illustrations enhance explanations of the immune system
Download or read book The Mononuclear Phagocyte System in Infectious Disease written by Geanncarlo Lugo-Villarino and published by Frontiers Media SA. This book was released on 2019-10-04 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mononuclear Phagocyte System (MPS) of vertebrates is composed of monocytes, macrophages and dendritic cells. Together, they form part of the first line of immune defense against a variety of pathogens (bacteria, fungi, parasites and viruses), and thus play an important role in maintaining organism homeostasis. The mode of transmission, type of replication and mechanism of disease-causing differ significantly for each pathogen, eliciting a unique immune response in the host. Within this context, the MPS acts as both the sentinel and tailor of the immune system. As sentinels, MPS cells are found in blood and within tissues throughout the body to patrol against pathogenic insult. The strategy to detect 'microbial non-self' relies on MPS to recognize conserved microbial products known as 'pathogen-associated molecular pattern' (PAMPs). PAMPs recognition represents a checkpoint in the response to pathogens and relies on conserved 'pattern recognition receptors' (PRRs). Upon PRR engagement, MPS mount a cell-autonomous attack that includes the internalization and compartmentalization of intracellular pathogens into toxic compartments that promote destruction. In parallel, MPS cells launch an inflammatory response composed of a cellular arm and soluble factors to control extracellular pathogens. In cases when innate immunity fails to eliminate the invading microbe, MPS serves as a tailor to generate adaptive immunity for pathogen eradication and generation of "memory" cells, thus ensuring enhanced protection against re-infection. Indeed, MPS cell functions comprise the capture, process, migration and delivery of antigenic information to lymphoid organs, where type-1 immunity is tailored against intracellular microbes and type-2 immunity against extracellular pathogens. However, this potent adaptive immunity is also a double-edge sword that can cause aberrant inflammatory disorders, like autoimmunity or chronic inflammation. For this reason, MPS also tailors tolerance immunity against unwanted inflammation. Successful clearance of the microbe results in its destruction and proper collection of debris, resolution of inflammation and tissue healing for which MPS is essential. Reciprocally, as part of the evolutionary process taking place in all organisms, microbes evolved strategies to circumvent the actions bestowed by MPS cells. Multiple pathogens modulate the differentiation, maturation and activation programs of the MPS, as an efficient strategy to avoid a dedicated immune response. Among the most common evasion strategies are the subversion of phagocytosis, inhibition of PRR-mediated immunity, resistance to intracellular killing by reactive oxygen and nitrogen species, restriction of phagosome maturation, modulation of cellular metabolism and nutrient acquisition, regulation of cell death and autophagy, and modulation of pro-inflammatory responses and hijacking of tolerance mechanisms, among others. The tenet of this eBook is that a better understanding of MPS in infection will yield insights for development of therapeutics to enhance antimicrobial processes or dampen detrimental inflammation for the host's benefit. We believe that contributions to this topic will serve as a platform for discussion and debate about relevant issues and themes in this field. Our aim is to bring expert junior and senior scientists to address recent progress, highlight critical knowledge gaps, foment scientific exchange, and establish conceptual frameworks for future MPS investigation in the context of infectious disease.
Download or read book Updates on Brucellosis written by Manal Mohammad Baddour and published by BoD – Books on Demand. This book was released on 2015-11-19 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brucellosis is a major zoonotic disease that may cause a serious illness in humans and animals. Global prevalence of human brucellosis remains significant. More than half a million new brucellosis cases from 100 countries are reported annually to the World Health Organization (WHO). The majority of these cases are reported in developing countries.In humans, brucellosis (undulant fever, Malta fever) is characterized by an acute bacteremic phase followed by a chronic stage that may extend over many years and may involve many tissues. It is a systemic disease, and many organ systems (nervous system, heart, skeletal system, bone marrow, etc.) may become involved following hematogenous dissemination. Although eradicated in some countries, it remains one of the most economically important zoonosis worldwide as it is responsible for huge economic losses as well as significant human morbidity in endemic areas. Because of the nonspecific clinical manifestations of human brucellosis and the need for prolonged combination therapy with antibiotics that are not routinely prescribed for other infectious diseases, laboratory confirmation of the diagnosis is of paramount importance for adequate patient management. In addition, evidence of brucellosis has serious public health implications because it discloses exposure to a contaminated source (infected animals or their products, unsafe laboratory practices, or a potential biological warfare attack). This book addresses human brucellosis with stress on symptoms including those related to the less recognized disease localizations, risk of exposure, treatment, and prevention. Light is shed on animal brucellosis as it pertains to human exposure. The book also emphasizes on laboratory procedures in culturing and serologic techniques. Epidemiologic surveillance is among this books subjects as well as veterinary control measures.
Download or read book Phagocytosis Microbial Invasion written by S. Gordon and published by Elsevier. This book was released on 2000-01-27 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume focuses on microbial invasion strategies of pathogen uptake. An accompanying volume (Vol. 5) in the series presents the phagocytic process from the viewpiont of the host cell. This field of study is growing rapidly after a somewhat slow start over recent decades. This collection of invited chapters attempts to reflect current research and brings together cell biologists, microbiologists, and immunologists wiht disthemes, hopefully like a symphony rather than a boring catalogue. It will be evident that editorial bias favors intracellular parasitism and medically important organisms. The neutrophil is far more than a supporting player to the macrophage and some attempt is made to remind the reader of some of its unique skills. To retain a manageable size, the emphasis is on relatively early events such as mutual recognition, cell entry, and response, rather than on longterm changes in gene expression by either host cell or pahtogen. Viruses are excluded not because of lack of importance but because of somewhat different research approaches, although it is becoming increasingly clear that large viruses (e.g. Vaccinia) and Listeria monocytogenes, share common strategies in invasion and intercellular spread.

Download or read book Pharmacology written by John Hadden and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive treatise on the reticuloendothelial system is a project jointly shared by individual members of the Reticuloendothelial (RE) Society and bio medical scientists in general who are interested in the intricate system of cells and molecular moieties derived from those cells which constitute the RES. It may now be more fashionable in some quarters to consider these cells as part of what is called the mononuclear phagocytic system or the lymphoreticular sys tem. Nevertheless, because of historical developments and current interest in the subject by investigators from many diverse areas, it seems advantageous to present in one comprehensive treatise current information and knowledge con cerning basic aspects of the RES, such as morphology, biochemistry, phylogeny and ontogeny, physiology, and pharmacology as well as clinical areas including immunopathology, cancer, infectious diseases, allergy, and hypersensitivity. It is anticipated that, by presenting information concerning these apparently het erogeneous topics under the unifying umbrella of the RES, attention will be focused on the similarities as well as interactions among the cell types constitut ing the RES from the viewpoint of various disciplines. The treatise editors and their editorial board, consisting predominantly of the editors of individual vol umes, are extremely grateful for the enthusiastic cooperation and enormous task undertaken by members of the biomedical community in general and especially by members of the American as well as European and Japanese Reticuloen dothelial Societies.
Download or read book Mononuclear Phagocytes written by R. van Furth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixteen years have passed since the first Leiden Conference on Mononuclear Phagocytes. That first meeting led to new nomenclature, i. e. , the Mononuclear Phagocytes System (MPS), which was published in the Bulletin of the World Health Organization (R. van Furth, et aI. , Bull. WHO, 1972, 46: 845-852). The paradigm of the MPS has the advantage of being much more consistent than the Reticuloendothelial System (RES) (L. Aschoff, Ergebn. Inn. Med. Kinderheilk. 1924, 26:1), because cells with similar characteristics can be classified in the same category. The essence ota new concept is, according to Popper, that it must be susceptible to falsification. This has been attempted several times for the MPS by those who adhere to the RES. However, in biology no one can be certain of truth. Any theory must be based on experimental observations and/or theoretical consider ations and both should be presented in such a way that others can try to refute it, then or later. One may have a theoretical or a pragmatic preference for a theory which at a given time is regarded as possibly truc, but later it may be shown to be false. In other words, what we present in this volume is regarded as true at this moment, but others may consider it as not true and try to disprove it. Controversies often stimulate new research.
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 Immunity written by Luba Vikhanski and published by Chicago Review Press. This book was released on 2016-04-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Around Christmas of 1882, while peering through a microscope at starfish larvae in which he had inserted tiny thorns, Russian zoologist Elie Metchnikoff had a brilliant insight: what if the mobile cells he saw gathering around the thorns were nothing but a healing force in action? Metchnikoff's daring theory of immunity—that voracious cells he called phagocytes formed the first line of defense against invading bacteria—would eventually earn the scientist a Nobel Prize, shared with his archrival, as well as the unofficial moniker "Father of Natural Immunity." But first he had to win over skeptics, especially those who called his theory "an oriental fairy tale." Using previously inaccessible archival materials, author Luba Vikhanski chronicles Metchnikoff's remarkable life and discoveries in the first moder n biography of this hero of medicine. Metchnikoff was a towering figure in the scientific community of the early twentieth century, a tireless humanitarian who, while working at the Pasteur Institute in Paris, also strived to curb the spread of cholera, syphilis, and other deadly diseases. In his later years, he startled the world with controversial theories on longevity, launching a global craze for yogurt, and pioneered research into gut microbes and aging. Though Metchnikoff was largely forgotten for nearly a hundred years, Vikhanski documents a remarkable revival of interest in his ideas on immunity and on the gut flora in the science of the twenty-first century.
