The concepts of the neuroendocrine system and the immune system emerged more or less simultaneously in the second half of the 20th century. Although these systems have a high degree of autonomy, it has also become clear that they interact in many ways and at different levels. This book focuses on the neuroendocrine and immune interactions that are fundamental to normal development and maintenance of health. The first introductory chapters are devoted to the historical and philosophical concepts within the field, as well as evolutionary considerations, offering critical interdisciplinary perspectives on the development of this field of research. Without attempting an exhaustive overview, the book then introduces some of the regulatory pathways that mediate interactions between the neuroendocrine and immune systems and examines modulating factors such as age and sex. In addition, several chapters address the importance of neuroendocrine-immune interactions in some disease states. Readers can expect to gain a broad perspective of neuroendocrine-immune interactions in development, health, and disease, along with a critical evaluation of current methods used in the field. Given its scope, the book is essential reading for undergraduate and graduate students with an interest in neuroendocrinology, neuroimmunology, and neuroscience, as well as postdoctoral fellows and established researchers seeking a comprehensive overview and historical perspective of the field of neuroendocrine-immune interactions.

Interactions between the immune, endocrine and nervous systems seldom appear as main issues in the neurosciences and in immunology. So far this was most likely due to the need to focus on the molecular and cellular bases of single neural, endocrine and immune processes. But hormones, neurotransmitters and neuropeptides can also influence more subtle mechanisms underlying immune cell activity. The contents of this volume aim at listing some aspects which show that not only the bases for neuroendocrine control of more refined mechanisms related to the organization and functioning of the immune systems to exist, but also that the immune system can actively communicate with neuroendocrine structures. The evidence is divided into three categories: - Anatomical, cellular and molecular bases for the exchange of information between immune, endocrine and neural cells, - reciprocal effects between immune and neuroendocrine mechanisms, and - immune-neuroendocrine regulatory circuits. Immunologically triggered neuroendocrine responses can be either beneficial or deleterious for the host. A systematic approach would imply the simultaneous evaluation of neuroendocrine and immune parameters and thus provide the basis for therapeutic interventions based on antagonizing or blocking undesirable effects.

Brain-immune interactions are essential to maintain health and their dysfunction contributes to diverse human diseases. Recent data show that haematopoietic processes and immune organs are under central autonomic control. Deficient regulation of inflammatory events contributes to brain diseases, whereas acute or chronic brain injury is linked with the development of systemic inflammatory conditions or immunosuppression. At present, common disorders with high socio-economic burden such as cancer, cardiovascular-, neuroinflammatory- and neurodegenerative diseases, asthma, allergies, autism, psychiatric conditions and sepsis are believed to be influenced, at least in part, by the dysfunction of brain-immune communication. Since the median age of the world's population is increasing rapidly, it is expected that the burden of common non-communicable diseases will further increase, which represents a huge challenge to the health care systems worldwide. Thus, there is an increasing demand to understand and treat complex diseases, many of which are age-related, and this is not possible unless the fine-tuned communication between large systems -such as the nervous and the immune system- is comprehensively understood. Although it is impossible to cover all areas of relevant research in this field, papers in this eBook give some insight to a few important aspects of brain-immune interactions and their contribution to disease. We hope that this collection could stimulate further relevant research and facilitate discussions to support the understanding of the highly complex interactions between the immune system and the brain in health and disease.

This informative publication updates the study of interaction of the nervous and endocrine systems with the immune system in the body. It describes the anatomical basis of these interactions, reviewing the innervation of lymphoid tissue and mast cells. The book discusses the effect of the endocrine system on immune function, including the relation of sex to the immune response. Emphasis is given to opioids, substance P, neurotensin, vasoactive intestinal peptide, somatostatin and cholecystokinin. Also addressed is the immunoregulatory effect of leukotrienes and platelet-activating factors. Scrutinized within are stress as an aspect of neuro-immune interactions, and the central role of the hypothalamus in this context. The book reviews the eye and the gastrointestinal tract with respect to the coordination of the nervous, endocrine, and immune systems in serving these organs. This work is of particular value to those in immunology, endocrinology, gastroenterology, and developmental biology.

In the last decades, several in vitro and in vivo studies have revealed the existence of a very complex network between the neuroendocrine and immune system. Important molecular mechanisms underlying these interactions, in both physiological and pathological conditions, have also been described. Indeed, hormones play a pivotal role in the development and functional regulation of the immune system – both innate and acquired responses. Immune system cells present specific hormone receptors and themselves produce some hormones, thus influencing hormone secretion. More recently, the modulation of hormone secretion has been attempted for treating associated autoimmune disorders, further supporting the strong interplay between the endocrine and immune system. Distinguished experts, who have published extensively in their fields, have contributed comprehensive chapters to this volume. The focus is on the various aspects of endocrine-neuro-immune connections, providing an updated panorama - from basics to clinical applications - of current knowledge and still debated issues.
