The importance of insects for human welfare is unquestionable. This laboratory manual summarizes a number of key methods used by insect immunologists around the world. It should be helpful for those already working in this field & especially for scientists with general interest in this research topic as a methodical guide for the first steps. The experiments are described in detail, with step-by-step directions. Basic procedure for activation, detection, quantification & characterization of cellular & humoral defense reactions are given, along with protocols for more detailed investigations of cell differentiation & isolation of insect immune factors. Population genetic aspect, viral pathology & comparative studies revealing similarities with the vertebrate immune system are also included. The result described in the chapters show remarkable progress in our understanding of insect immunology. Simultaneously, the large number of still-unanswered questions make us realize that we have a lot left to learn about these fascinating animals. From future investigation we can expect a better understanding of the immune system's evolution, the discovery of new antimicrobial & regulatory insect molecules potentially useful in the therapy of human disease & new strategies for insect control.

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

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.

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.

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.

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.
