Immunity To Parasitic Infection

Parasitic infections remain a significant cause of morbidity and mortality in the world today. Often endemic in developing countries many parasitic diseases are neglected in terms of research funding and much remains to be understood about parasites and the interactions they have with the immune system. This book examines current knowledge about immune responses to parasitic infections affecting humans, including interactions that occur during co-infections, and how immune responses may be manipulated to develop therapeutic interventions against parasitic infection. For easy reference, the most commonly studied parasites are examined in individual chapters written by investigators at the forefront of their field. An overview of the immune system, as well as introductions to protozoan and helminth parasites, is included to guide background reading. A historical perspective of the field of immunoparasitology acknowledges the contributions of investigators who have been instrumental in developing this field of research.

Parasites cause many important diseases in humans and domestic animals, malaria being an example. Parasites have evolved to exploit hosts' bodies whereas hosts have evolved immune systems to control infections. Host-parasite interactions therefore provide fascinating examples of evolutionary 'arms-races' in which the immune system plays a key role. Modern research in immunoparasitology is directed towards understanding and exploiting the capacity to develop effective anti-parasite immunity. By concentrating on selected infections where research has made significant progress, Immunity to Parasites provides a clear account of how host immune responses operate and how parasites can evade immunity. The experimental basis of this research is emphasised throughout. This completely updated second edition includes an expanded section on anti-parasite vaccines. The text is aimed at undergraduates and postgraduates with interests in either parasitology or immunology and provides introductory sections on these topics to lead the reader into the later chapters.

We acknowledge the initiation and support of this Research Topic by the International Union of Immunological Societies (IUIS). We hereby state publicly that the IUIS has had no editorial input in articles included in this Research Topic, thus ensuring that all aspects of this Research Topic are evaluated objectively, unbiased by any specific policy or opinion of the IUIS.

Featuring the work of several world authorities, this volume places primary emphasis on the mechanism of parasite produced changes in the immune response (i.e. immunosuppression). The text covers parasitic diseases on which the World Health Organization has aggressively promoted research through its Program on Research and Training In Tropical Diseases. Chapters cover parasitic diseases such as malaria, American trypanosomiasis (Chagas' disease), African trypanosomiasis (sleeping sickness), leishmaniasis, schistosomiasis and onchocerciasis. Also included are discussions of toxoplasmosis and amebiasis. The material is drawn from the body of literature that has been rapidly accumulating for the last 15 years. An important feature of this text is that the contributors first outline existing knowledge about the immunology of each infection, thereby enabling the reader to more easily appreciate why and how the immunological alterations that accompany a disease are important, and then, to review the postulated mechanisms for such alterations. Consequently, the impact that each parasitic infection has on the immune system is always described in the "heart" of each chapter rather than at the beginning.

The book focuses on various aspects and properties of innate immunity, whose deep understanding is integral for safeguarding the human race from further loss of resources and economies due to innate immune response-mediated diseases. Throughout this book, we examine the individual mechanisms by which the innate immune response acts to protect the host from pathogenic infectious agents and other non-communicable diseases. Written by experts in the field, the volume discusses the significance of macrophages in infectious disease, tumor metabolism, and muscular disorders. Chapters cover such topics as the fate of differentiated macrophages and the molecular pathways that are important for the pathologic role of macrophages.
