The Immune Neuroendocrine Circuitry

The book summarises the current understanding of the Nervous -, Endocrine and Immune systems with emphasis on shared mediators and receptors and functional interaction. In addition to the fundamental physiological and pathophysiological mechanisms, which are presented in detail, some clinically relevant subjects are also presented, such as inflammation, asthma and allergy, autoimmune disease, immunodeficiency and the acute phase response. • A comprehensive presentation of neuroimmune biology • Introduces the subject matter to the uninformed reader • Contains basic information, theoretical considerations and up-to-date clinical chapters • The clinical chapters will be helpful to practising physicians

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.

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.

This authoritative handbook covers all aspects of immunosenescence, with contributions from experts in the research and clinical areas. It examines methods and models for studying immunosenescence; genetics; mechanisms including receptors and signal transduction; clinical relevance in disease states including infections, autoimmunity, cancer, metabolic syndrome, neurodegenerative diseases, frailty and osteoporosis; and much more.

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.

Is this a time for a sleeping giant to rise? We have known since study of the lymphocyte and plasma cells really began in earnest in the early 1940's that the pituitary adrenal axis under intimate control of the hypothalamus could influence immunological functions profoundly. We have also known for at least 20 years in my recollection that female sex hor mones can maximize certain immunity functions while male sex hormones tend to suppress many immunological reactions. The thyroid hormones accelerate antibody production while at the same time sp~eding up de gradation of antibodies and immunoglobulins and thyroidectomy decreases the rate of antibody production. Further, much evidence has accumulated indicating that the brain, yes even the mind, can influence in significant ways susceptibility to infections, cancers and to development of a variety of autoimmune diseases. More than 20 years ago, my colleagues and I convinced ourselves, if no one else, that hypnosis can exert major in fluences on the effector limb of the classical atopic allergic reactions. We showed with Aaron Papermaster that the Prausnitz-Kustner reaction may be greatly inhibited, indeed largely controlled, by post-hypnotic suggestion. And it was not even necessary for us to publish our discovery because scientists in John Humphrey's laboratory at Mill Hill Research Center in London had beaten us to the punch. They described hypnotic control of both the PK reaction and delayed allergic reactions to tuberculin by hypnosis.

Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.
