Although, Phagocytosis was first described nearly 120 year ago, we are just recently beginning to understand the molecules that phagocytic cells use to bring about this complex cell function. Molecular Mechanisms of Phagocytosis was prepared as a series of up-to-date essays (chapters) that describe the present knowledge on the various steps of the phagocytic process from initial cell contact, through internalization of the foreign particle, to the final phagosome formation where the phagocytosed particle is destroyed.

Phagocytosis has been at the forefront of cell biology for more than a century. Initially, phagocytosis, which comes from Greek words meaning “devouring cells,” was discovered in the late 19th century by Ilya Metchnikoff, who was awarded, together with Paul Ehrlich, the Nobel Prize in Physiology and Medicine in 1908 “in recognition of their work on immunity.” At that time Metchnikoff had already identified a function for phagocytes not only in host defense but also as scavengers of degenerating host cells during metamorphosis of tadpoles, thus providing one of the first descriptions of apoptotic cell clearance by macrophages (Kaufmann 2008). Since then, much has been learned about phagocytosis, and the previous several decades have witnessed outstanding progress in understanding the functions and the molecular mechanisms of phagocytosis. Two main types of targets are cleared by phagocytosis: microbial pathogens and dying cells. Rapid recognition and clearance of dying cells by phagocytes plays a pivotal role in development, maintenance of tissue homeostasis, control of immune responses, and resolution of inflammation. Clearance of dying cells can be divided into several stages, including sensing, r- ognition, binding and signaling, internalization, and immunological responses. In this book, our contributors address these different stages of dead cell cle- ance and examine how impaired clearance of dying cells may lead to human d- eases. We have attempted to provide sufficient cross-referencing and indexing to enable the reader to easily locate the ideas elaborated in the different chapters.

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.

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.

Phagocytosis is an evolutionarily conserved mechanism that serves as the first line of host defense in multicellular organisms. The traditional definition of phagocytosis involves the engulfment and degradation of large solid particles (>0.5 μm), initiated by receptor activation on phagocytes. It forms an essential aspect of innate immunity through the uptake and destruction of infectious pathogens, while also participating in the removal of apoptotic cells during tissue remodeling and development. Professional phagocytes, such as macrophages, neutrophils, and dendritic cells, are well equipped with a wide range of phagocytic receptors. In addition, these specialized leukocytes can signal to lymphocytes within the adaptive arm of host immunity. This review emphasizes the role of two well-characterized opsonic receptors, the Fcγ receptor and the complement receptor, CR3 in macrophages. In particular, it focuses on the different mechanisms employed by these receptors during particle recognition and phagocytic uptake. Bacterial species often manipulate phagocyte signaling in order to evade their engulfment and degradation and consequently provide further insight into key regulators of the phagocytic process. Finally, we draw attention to the physiological relevance of studying the simultaneous engagement of multiple phagocytic receptors, in order to better understand receptor crosstalk and the underlying coordination of downstream signaling for efficient phagocytosis.
