Book Description
Immunoregulation is one of the areas which has witnessed the most explosive advances of immunology during the past decade. It is in this area that the current view of the immune system has arisen and developed. There is indeed little doubt that immune reactions are primarily determined by messages which are genera ted within the immune system and passed among different types of immunologie cells. This cell communication not only determines the type, intensity and duration of the response after perturbation of the immune system by exogenous antigens, but it is also essential for preventing autoimmune reactions and their clinical conse quences. In order to assure aperfect balance within the enormous com plexity of the immune system, it is not surprising that multiple self-regulatory mechanisms are organized at different levels, such as antibody feedback, idiotypic-anti-idiotypic responses, suppres sor and helper T cells, lymphokine signals and genetic require ments. A nu mb er of observations in recent years have, however, demonstrated that consistent contributions to the immunological homeostasis are given also by signals generated outside of the immune system, namely,in the central and autonomous nervous system as weIl as in the endocrine apparatus. Furthermore, the interactions between the immune system and the other body homestatic mechanisms seem to be bidirectional: if immunological cells may be targets of neuroendocrinological factors, immunological products seem in turn to contribute to the neuro endocrine homeostasis.

Book Description
Aging inspired a large number of theories trying to rationalize the aging process common to all living beings. In this publication the most important environmental and intrinsic mechanisms involved in the aging process and in its pathological consequences are reviewed. Furthermore theoretical and experimental evidence of the most important theoretical elements based on Darwinian evolution, cellular aging, role of cell membranes, free radicals and oxidative processes, receptor-mediated reactions, the extracellular matrix and immune functions as well as the most important environmental and intrinsic mechanisms involved in the aging process and in its pathological consequences are discussed. These presentations of theories and related experimental facts give a global overview of up to date concepts of the biology of the aging process and are of essential reading not only for specialists in this field but also for practitioners of scientific, medical, social and experimental sciences.

Book Description
Methods in Toxicology, Volume 2: Mitochondrial Dysfunction provides a source of methods, techniques, and experimental approaches for studying the role of abnormal mitochondrial function in cell injury. The book discusses the methods for the preparation and basic functional assessment of mitochondria from liver, kidney, muscle, and brain; the methods for assessing mitochondrial dysfunction in vivo and in intact organs; and the structural aspects of mitochondrial dysfunction are addressed. The text also describes chemical detoxification and metabolism as well as specific metabolic reactions that are especially important targets or indicators of damage. The methods for measurement of alterations in fatty acid and phospholipid metabolism and for the analysis and manipulation of oxidative injury and antioxidant systems are also considered. The book further tackles additional methods on mitochondrial energetics and transport processes; approaches for assessing impaired function of mitochondria; and genetic and developmental aspects of mitochondrial disease and toxicology. The text also looks into mitochondrial DNA synthesis, covalent binding to mitochondrial DNA, DNA repair, and mitochondrial dysfunction in the context of developing individuals and cellular differentiation. Microbiologists, toxicologists, biochemists, and molecular pharmacologists will find the book invaluable.

Book Description
Glucocorticoids regulate multiple metabolic and developmental processes and play a vital role in the maintenance of basal and stress-related homeostasis. For the last 50 years, pharmacologic doses of glucocorticoids have been used in the treatment of inflammatory, autoimmune, and lymphoproliferative diseases and in the prevention of allograft rejection, while substitution doses have been employed in the management of adrenocortical insufficiency. aspects of glucocorticoid action, in particular, (i) the impact of maternal and early life stress on stress-related gene regulation in the offspring; (ii) the importance of glucocorticoids and their receptors; (iii) further understanding of the mechanisms of GR action, including its effect on chromatin modulation, its interaction with coactivators and corepressors, and the genetic dissection of GR function in mice; (iv) The interaction of hGR with other transcription factors, such as NF-kappa-B, p53, transforming growth factor beta (TGF-beta) and the chicken ovalbumin upstream promoter transcription factor II (COUP-TFII); recycling, ubiquitination and degradation of the receptor, actions of the GR-beta isoform, a novel synthetic nonsteroidal target gene-specific agonist, the importance of target tissue activity of 11-beta-hydroxysteroid dehydrogenase type 1 in glucocorticoid action in health and disease, the interaction of the receptor with the nutrient carnitine, the anthrax products protective antigen (PA) and lethal factor (LF), and the human immunodeficiency virus type-1 (HIV-1)-encoded molecules Vpr and Tat; (vi) an update on the effects of glucocorticoids on the immune system; and (vii) the clinical implications of glucocorticoid action, including glucocorticoid resistance/hypersensitivity, familial and sporadic glucocorticoid resistance, and the effects of stress and depression.

Book Description
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.
