Book Description :

In insect and other arthropod immune systems, discrimination between self and nonself tissues is accomplished through the combined actions of two immunocytes and several humoral factors. Immunology of Insects and Other Arthropods presents a comprehensive look at this and other important topics in arthropod immunology. Issues discussed include insect immunocytes and other hemocytes, including computer image analysis of immunocyte serial sections; the two basic cellular immune reactions (phagocytosis and encapsulation), including the molecular basis and roles of gap junctions in encapsulation; how encapsulation is affected by polydnavirus and encapsulation-promoting factors; why insect cells are immune to HIV; humoral factors; and antibacterial factors in Lepidoptera, Diptera, and other insect orders. Other topics include hemolymph proteins interacting with mammalian complement cascade; adaptive humoral response in the American cockroach; antigenic stimulation of hemaglutinin production in insects; and the applications of the Limulus Amebocyte Lysate (LAL) in detecting endotoxins in pharmaceuticals, medical devices, clinical diagnosis, and hygienic control. This book represents an important reference source for hematologists, pathologists, immunologists, AIDS researchers, comparative immunologists, and pharmaceutical companies.

Book Description :

Rhodnius prolixus is a bloodfeeding hemipteran insect and a vector of Trypanosoma cruzi, the etiologic agent of Chagas disease. This disease affects over 18 million people in Latin America, and there are no vaccines or efficacious drugs. Because of the unique lifecycle of T. cruzi within the vector, and its avoidance of the hemocoel where the primary immune response occur, we investigated the role of the innate immune response of R. prolixus to pathogens and parasites, including T. cruzi. Insect immunity is based on three principles: pathogen recognition, induction of appropriate regulatory pathways; and the production of molecules to eliminate the pathogens. In this dissertation, I use functional genomics (Suppressive Subtractive Hybridization) to identify and describe genes involved in the immune response of R. prolixus and the implications for T. cruzi. Initially we identified expressed sequence tags (ESTs) corresponding to genes that are differentially expressed in response to parasites and bacteria, and assigned putative gene functions based on sequence similarities. This thesis focuses on four genes of interest including a transcription factor (Dorsal), which may function in the regulation of expression of immune peptides, and three antimicrobial peptides (Defensin, Lysozyme and Prolixin) that serve directly to eliminate pathogens. Transcriptional factor binding motifs (NF-KB) present in the promoters of two of these genes (lysozyme and defensin) suggest they are transcriptionally regulated by Dorsal, whereas prolixin is not. We evaluated the temporal and spatial expression profiles of the antimicrobial peptide genes, using real time quantitative PCR, to establish molecular relationships between parasite and vector. Subsequently, we expressed dorsal and prolixin in bacteria and tested their functions. We concluded that invasion of the hemocoel of R. prolixus activates components of the immune system and the production of compounds lethal to T. cruzi, but the pathogen survives by living exclusively in the intestine avoiding vector responses. This study contributes to our overall knowledge of insect immunity, the arsenal of immune molecules available to different insects, and identifies novel and highly conserved immune molecules found in higher and lower insects.

Book Description :

Insects are the most numerous and diverse group of animals on earth, not only in number of individuals, but also in number of species. They inhabit virtually all terrestrial and freshwater environments, where they must protect themselves from an array of commensal, pathogenic and parasitic organisms that share the same ecological niches. Since the early 20th century, scientists have been intrigued by how insects defend themselves against microbial attack. We are currently witnessing a break-through in our understanding of the mechanisms governing immune reactions in insects. Molecular Mechanisms of Immune Responses in Insects covers various aspects of these mechanisms starting with a historical chapter on the origins of insect immunity. There are also chapters that cover antibacterial peptides from insects and their mode of action, relationships between insect defense proteins and development and immune mechanisms in vectors of transmissible disease. Other key areas covered include antibacterial peptides of the insect reproductive tract, regulation of insect immune genes and immune protein cascades, as well as a chapter on the cellular tools that revolutionized the study of molecular mechanisms of the insect immunity. Molecular Mechanisms of Immune Responses in Insects is written for a broad audience ranging from specialists in the field of innate immunity to informed biologists and graduate students fascinated by the simplistic efficiency of a `primitive' immune system. Fully up-to-date, this volume presents the reader with the most significant work from the major laboratories throughout the world. The contributors to the book reflect, both in concept and style, the international dimension of this area of science.

Book Description :

Under continual attack from both microbial pathogens and multicellular parasites, insects must cope with immune challenges every day of their lives. However, this has not prevented them from becoming the most successful group of animals on the planet. Insects possess highly-developed innate immune systems which have been fine-tuned by an arms race with pathogens spanning hundreds of millions of years of evolutionary history. Recent discoveries are revealing both an unexpected degree of specificity and an indication of immunological memory - the functional hallmark of vertebrate immunity. The study of insect immune systems has accelerated rapidly in recent years and is now becoming an important interdisciplinary field. Furthermore, insects are a phenomenally rich and diverse source of antimicrobial chemicals. Some of these are already being seriously considered as potential therapeutic agents to control microbes such as MRSA. Despite a burgeoning interest in the field, this is the first book to provide a coherent synthesis and is clearly structured around two broadly themed sections: mechanisms of immunity and evolutionary ecology. This novel text adopts an interdisciplinary and concept-driven approach, integrating insights from immunology, molecular biology, ecology, evolutionary biology, parasitology, and epidemiology. It features contributions from an international team of leading experts. Insect Infection and Immunity is suitable for both graduate students and researchers interested in insect immunity from either an evolutionary, genetical, physiological or molecular perspective. Due to its interdisciplinary and concept-driven approach, it will also appeal to a broader audience of immunologists, parasitologists and evolutionary biologists requiring a concise overview.

Book Description :

Innate immunity is a new branch of immunology, confirmed by three Nobel Prize winners in 2011. It is the first line of defense against pathogens and is in a way the preliminary step of adaptive immunity which occurs later, and only present in vertebrates. This book examines the way in which innate immunity was discovered in invertebrates. As a starting point, it looks at the work of Louis Pasteur on silkworm disease and the findings of Ilya Metchnikov, discoverer of phagocytosis. It also investigates André Paillot, who in 1920 demonstrated the existence of humoral immunity in insects, unrelated to the type of immunity that was initially thought to be present in all vertebrates. Finally, Innate Immunity shows how the group directed by Jules Hoffmann found strong similarities between the innate immunity response of insects and mammals. The discovery of a receptor protein in Drosophila, which is also found in humans, was what led to Jules Hoffmann being awarded the Nobel Prize in 2011. Presents the transformations experienced by the domains of innate immunity Shows the lineage of these results Bridges the gap between innate immunity of invertebrates and that of vertebrates

Book Description :

Immunity in insects is different from immunity in vertebrates. Insects lack immunoglobulins even though they are capable of reacting against foreign components with effective defense mechanism. There has been a marked advancement in most of the fields of science in the past two decades. Insect immunity is also one of them. It is a developing subject which is now established as a new branch in insect study. This treatise is an attempt to compile meaningful articles of leading workers in this field, nevertheless we do not claim that leadership in insect immunity is by any means restricted to them. The idea is to provide a vibrant description of various aspects of "Insect Immunity". With the rapid development of the subject, it is difficult for any one author to discuss all the aspects of an area in a limited number of pages, even then they have done their utmost to include the entire development of the subject in their articles. The treatise deals with insect haemocytes, their population, isolation and role in defense mechanism, humoral encapsulation, inducible humoral antibacterial immunity, cellular immune reactions, role of endocrines, role of prophenol oxidase system in cellular communication, haemagglutinins and impact of parasite on insect immune system. Some topics could not be covered because experts in those area though willing could not complete their commitment within time limits.

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 :

Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the study of ento mology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances some times depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been sufficiently ironed out to permit students to master the manipulations in a few laboratory periods. Many specialized techniques are confined to one specific research labora tory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in method ology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which may be appli cable for use in biology laboratory courses.

Book Description :

This comprehensive book thoroughly covers the field of stinging insect allergy; addressing all clinical aspects, including diagnosis and therapeutic recommendations. Stinging Insect Allergy: A Clinician’s Guide begins with a look into the entomologic aspects of Hymenoptera insects (bees, vespids, wasps and ants), which cause nearly all the IgE mediated reactions due to insects. Further chapters single out and examine the unique aspects of common Hymenoptera species, such as bees and fire ants, in rich detail. Later chapters clinically review what is known about non-Hymenoptera biting insects, such as mosquitoes. In addition, multiple chapters address the overlap of Hymenoptera allergy as practiced in North America and Europe, as well as other sciences. Final chapters cover the impact ecology is having on insect allergy; and the impact insect allergy is having on other areas of medicine, such as mast cell disorders. Stinging Insect Allergy: A Clinician’s Guide is an ideal resource for medical students, residents, allergists, and general practitioners alike, and also serves as an important reference text for any practitioner of allergy and immunology who desires a complete picture of Hymenoptera and non-Hymenoptera insect allergy.

Book Description :

Several discoveries are noteworthy for allowing us to probe the recesses of the virus℗Ư infected cell and to search for cryptic viral genomes which might provide clues in our studies of cancer etiology or developmental biology. One of the most notable was the dis℗Ư covery of reverse transcriptase. This marked a momentous occasion in the history of molecular biology. Not only did it provide insight into the mechanism of persistence of retroviruses but it also provided us with an enzyme that could synthesize a DNA copy of any RNA. This DNA copy could then be used as a hybridization reagent to search for both complementary DNA and viral-specific RNA. Thus one could follow the course of any viral infection or probe in tumor cells for hidden viral genomes. Second, a great deal of credit must be given to the geneticists who isolated the various deletion mutants in the 'avian retrovirus system and thus provided us with the frrst means of isolating gene-spe℗Ư cific probes. Finally, the laboratories which have mapped the genome have provided us with the framework in which to ask very specific questions with our gene-specific probes. Recently, numerous excellent reviews concerning various aspects of the retroviruses have appeared. In this review I shall not even attempt to present a comprehensive review of retroviruses.
