Book Description
Immunology of Annelids provides a state-of-the-art review of the biological and biochemical processes involved in defense reactions of annelids. The book covers phylogeny, taxonomy, and fundamental body structure to provide basic information essential to developing a full understanding of the defense system of an organism. Physiological aspects of the relationship between the immune systems and cells and their limitations are discussed in detail, and the role of cells in cellular defense, transplantation, and humoral defenses is explained. The importance of annelids and their defense reaction from the phylogenetic standpoint is examined in a chapter comparing vertebrate and invertebrate defense strategies. Immunology of Annelids is a practical reference for cell biologists, immunologists, evolutionary and developmental biologists, and other researchers who need insight into the development and hierarchy of immune reactions.

Book Description
Immunologists, perhaps understandably, most often concentrate on the human immune system, an anthropocentric focus that has resulted in a dearth of information about the immune function of all other species within the animal kingdom. However, knowledge of animal immune function could help not only to better understand human immunology, but perhaps more importantly, it could help to treat and avoid the blights that affect animals, which consequently affect humans. Take for example the mass death of honeybees in recent years – their demise, resulting in much less pollination, poses a serious threat to numerous crops, and thus the food supply. There is a similar disappearance of frogs internationally, signaling ecological problems, among them fungal infections. This book aims to fill this void by describing and discussing what is known about non-human immunology. It covers various major animal phyla, its chapters organized in a progression from the simplest unicellular organisms to the most complex vertebrates, mammals. Chapters are written by experts, covering the latest findings and new research being conducted about each phylum. Edwin L. Cooper is a Distinguished Professor in the Laboratory of Comparative Immunology, Department of Neurobiology at UCLA’s David Geffen School of Medicine.

Book Description
It can be seen that the insects are the still attracting most research and researchers. However, an increasing interest is emerging to study new invertebrate groups, especially those where the genome is known. Even though Drosophila has been and still is an excellent model for immune studies, it is now clear that there are great differences between immune responses in Drosophila and that of several other invertebrates, which indeed calls for more research on other invertebrates

Book Description
Annotation This book is aimed at two audiences. First, it will present evidence for the earthworm's immune system. Second, the results strongly suggest that certain molecules of the earthworm's immune system may be exploited as natural antibiotics--thus the biomedical applications. There are two advantages for using earthworms. First, they are an inexpensive, non-controversial invertebrate model. Second, in contrast to other invertebrates (e.g. Drosophila, C elegans) they are essential for maintaining the integrity of soil. Earthworms have a highly effective immune system since cancer cannot be induced in them nor does it seem to occur in natural populations. Cytotoxicity of cancer cells has been examined in relation to two earthworm leukocytes based upon: structure; cell differentiation antigens; function revealed by FACS and mAbs. These cells are SMALL (8-11 m) electron dense (SC), positive for human cell adhesion molecules (CD11a, CD45RA, CD45RO, CDw49b, CD54, for?2-microglobulin and for Thy-1; LARGE (12-15 m) electron lucent cells (LC), negative for these same markers. Leukocytes synthesize and secrete lytic molecules (fetidins, CCF-1, lysenin, eiseniapore) participate in recognition of, binding to, killing and sequestration of cancer cells in vitro. Earthworm lytic levels are significantly higher than those of human NK cells. Earthworms possess a highly evolved, unique and efficient immune system that has facilitated long-term survival.

Book Description
The biological bases of invertebrate immune responses have interested scientists for decades, from the first relevant observation by E. Metchnikoff in 1882, who discovered phagocytosis while studying starfish larvae. Invertebrate immunology first began to be appre ciated as an important field in the late 1960s and 1970s. However, in the following years there was much controversy regarding the question: do invertebrates offer insight into the origin of the sophisticated immune responses of the vertebrates? There are several reasons why progress in research on invertebrate immune competence has been painfully slow. One of the main impediments to the progress, as compared to the fast development of knowledge in the vertebrate systems, was the fact that most of the studies concentrated on "whole organism" assays, mainly on grafting tissues between allogeneic partners. Only in the last few years have more and more aspects of invertebrate immunity been investigated on the cellular, biochemical and molecular levels. These studies led to discoveries of novel defense reactions, new pathways of effector mechanisms which are elicited after recognition of "nonself', and complex, sometimes highly polymorphic genetic elements that control invertebrate immune reactions. The importance of invertebrate immunity for understanding "immunology" as a whole, despite the conflicting models and hypotheses, is now much more recognized than before. Although most of the 20 phyla belonging to the inver tebrates have different modes of life, body organizations, habitats occupied, and biochemical patterns, they show striking aspects of exceptional precision for discriminating between self and nonself.

Book Description
E. L. Cooper In Volume 23 we considered, in seven chapters, the basic armamentarium of the invertebrate immune system and its cells, as well as an analysis of antigens, setting the stage for the initiation of an immune response. We studied cell products, natural or induced, as revealed by nonspecific and specific responses following antigenic challenge such as the pro phenol oxidase system, the lytic responses, the Ig superfamily, and the place this family offers invertebrates and insect hemolymph proteins as candidates for membership. At this point, these various topics seemed to converge, almost to overlap, in some instances, presenting a challenge as to how to move from one subject to another. Chapter 1, in this volume offers the bridge to Volume 23 and its final Chapter 7. This Volume 24 contains contributions pertaining to cell activities and the environment. Chapters 1-4 refer specifically to interactions between cells and the integration of cell activities. The focus is on a functional immune system, with antigenic challenge as a subtopic. In Chapters 5-7, the environment is considered from several points of view and the main subtopic here is the result of the consequences of connections and missed signals. The internal and external environments are treated, revealing what may happen when normal immune responses are interfered with. All this is integrated by the consideration of the three great regulatory systems, the ever-present network that somehow acts as the monitor or control for all incoming and outgoing signals.

Book Description
General Immunology provides a general overview of the immune system. It presents topics in immunology from all living groups, treating cells, tissues, organs, and organismal levels of biological organization. The book contains 23 chapters organized into eight sections. Section I serves as an introduction to immunology—a science, a sketch of its history, some of its more recent contributors, something about gathering facts, immunology journals, and the entire biomedical enterprise of which immunology is just a part. Section II is devoted to antigens while Section III examines the immune system in chordates and the ontogeny of the immune system. Section IV on cells of the immune system covers monocytes, macrophages, the three granulocytic types, and mast cells. Section V deals with phagocytosis and the interaction of lymphocytes. Section VI is devoted to antigens in relation to antibody synthesis, antigen-antibody interactions, immunologlobulin structure, and immunologlobulin assembly. Section VII on organs of the immune system examines bone marrow, thymus, spleen, lymph nodes, and lymphoid aggregations. Section VIII discusses the evolution of the immune system. This text was written for advanced undergraduates. However, its comprehensiveness makes it useful to immunologists and biologists at all levels as well as medical students and clinicians.

Book Description
Based on the assumption that invertebrates as well as vertebrates possess factors regulating hematopoiesis, response to infection or wounding, studies dealing with the evolution of immunity have focused on the isolation and characterization of putative cytokine-related molecules from invertebrates. Until recently, most of our knowledge of cytokine- and cytokine receptor-like molecules in invertebrates has relied on functional assays and similarities at the physicochemical level. As such, a phylogenetic relationship between invertebrate cytokine-like molecules and invertebrate counterparts could not be convincingly demonstrated. In the present book, recent studies demonstrating cytokine-like activities and related signaling pathways in invertebrates are critically reviewed, focusing on findings from molecular biology and taking advantage of the completion of the genome from the fly Drosophila and the worm Caenorhabditis elegans.
