The dysregulation of pro-inflammatory cytokines as a result of stress exposure has become widely implicated in the complex etiology of depression. Patients with depression have been shown to have elevated levels of pro-inflammatory cytokines both in plasma and cerebral spinal fluid. During times of stress pro-inflammatory cytokines are primarily regulated by glucocorticoids and catecholamines that work in opposition to one another to inhibit (glucocorticoid receptor) or stimulate (beta-adrenergic receptor) pro-inflammatory cytokine production. While chronic stress can lead to heightened levels of both glucocorticoids and catecholamines, it is not known how the dysregulation of these systems affect the regulation of pro-inflammatory cytokines. This dissertation focused its work through three aims. Aim 1 explored norepinephrine's regulation of microglial pro-inflammatory cytokines. Aim 2 examined sex differences in the regulation of brain IL-1 beta by glucocorticoids and catecholamines following chronic stress. Finally, aim 3 sought to uncover glucocorticoids effect on norepinephrine turnover. Together, these aims help to better understand how chronic stress alters the regulation of brain pro-inflammatory cytokines with implications for depression.

Within the past few years, it has become recognized that the immune system communicates to the brain. Substances released from activated immune cells (cytokines) stimulate peripheral nerves, thereby signaling the brain and spinal cord that infection/inflammation has occurred. Additionally, peripheral infection/inflammation leads to de novo synthesis and release of cytokines within the brain and spinal cord. Thus, cytokines effect neural activation both peripherally and centrally. Through this communication pathway, cytokines such as interleukin-1, interleukin-6 and tumor necrosis factor markedly alter brain function, physiology and behavior. One important but underrecognized aspect of this communication is the dramatic impact that immune activation has on pain modulation. The purpose of this book is to examine, for the first time, immune-to-brain communication from the viewpoint of its effect on pain processing. It is aimed both at the basic scientist and health care providers, in order to clarify the major role that substances released by immune cells play in pain modulation. This book contains chapters contributed by all of the major laboratories focused on understanding how cytokines modulate pain. These chapters provide a unique vantage point from which to examine this question, as the summarized work ranges from evolutionary approaches across diverse species, to the basics of the immune response, to the effect of cytokines on peripheral and central nervous system sites, to therapeutic potential in humans.

Until a few years ago, cytokines were only known to immunologists; now these molecules have burst upon neurosciences and permeated several avenues of current research. This book examines the possible role of cytokines in mental depression, based on recent clinical and experimental data, and constitutes the first attempt to make a synthesis between the exciting new developments in cytokine research and their implications for the pathophysiology of mental disorders.

Cytokines had been characterized in the early eighties as communication mole cules between immune cells, and between immunocytes and other peripheral cells, such as fibroblasts and endothelial cells. They play a key role in the regulation of the immune response and the coordination of the host response to infection. Based on these biological properties, nobody would have predicted that one decade later cytokines would burst upon neurosciences and permeate into several avenues of current research. In neurology, the connection between cytokines and inflammation, and the demonstration of a pivotal role of some of these molecules in cell death by apoptosis, prompted the investigation of their involvement in several neurological diseases involving an inflammatory component, including multiple sclerosis, brain trauma, stroke, and Alzheimer's disease. This movement started in the late eighties, and the corresponding field of research, known as neuroimmunology, is presently booming. In psychiatry, however, the relationship between cytokines and mental disorders was much less evident and took longer to materialize. The first indication that cytokines might be involved in psychopathology came from cancerology and internal medicine.

The brain and immune system are involved in an intricate network of bidirectional communication. This relationship is vital for optimal physiological and psychological development and functioning but can also result in unwanted outcomes. In particular, this interaction plays an important role in cognition, mood and behaviour. Neuroinflammation is known to contribute to neurological and affective disorders including impaired learning and memory, depressive, anxiety and schizoaffective symptoms, as well as pain. The development of these conditions often occurs on the backdrop of pre-existing physical illnesses which give rise to increased activation of the immune system, such as cancer, obesity, infection and autoimmune disorders. Similarly, psychological states can alter regulation of the immune system. This has been most extensively studied in the context of stress and immune function. Understanding the underlying mechanisms that lead to the onset of inflammation-induced neuropathology and stress-induced immune suppression will contribute to the development of novel and effective treatment strategies for both the disease and its neurological side effects. In this research topic we explored the relationship between the immune system and the brain throughout life. We include both original research and review papers from animal, clinical and molecular perspectives.

Cytokines and Mental Health explores the relationship between cytokines, neural circuitry and mental health. It is interdisciplinary and "translational", bringing together information that spans the spectrum from the molecular and cellular levels to the patient and the clinic. Content includes chapters that discuss cytokine pathways in the brain, the neurochemical and neuroendocrine effects of cytokines, and the behavioral effects of cytokines including sickness behavior. These chapters in basic research are followed by a more clinical section that discusses the role of cytokines in neuropsychiatric disorders such as major depression, schizophrenia and Alzheimer's disease. The book offers different things to different people. It should be of great interest to neuroscientists and immunologists working in the field of psychoneuroimmunology. It would also greatly benefit mental health professionals including psychiatrists, psychologists and clinicians of diverse background who are interested in mind-body medicine.

"Mechanisms of Neuroinflammation" book explains how the neuronal cells become swollen at the moment of the blood-brain barrier disruption and how they lose their immunological isolation. A cascade of cytokines and immune cells from the bloodstream enters the nervous system, inflaming neurons and activating the glia. This produces a neuroinflammatory process that can generate different neurodegenerative diseases. Better understanding of mechanisms that are activated at the time when the damage to the brain occurs could lead to the development of suitable therapies that revert the neuronal inflammation and thus prevent further damage to the nervous system.

Several new developments in the field of neuroimmunology with focus on the brain-to-immune system communication have been the incentive for this PIR volume. It covers topics such as brain-immune interactions, the impact of stress on the immune response, pain and immunosuppression, the modulation of inflammation and pain by the sympathetic nervous system, consequences of nerve injury for the immune system, neuronal mechanisms of immune cell recruitment, and the modulation of the immune response by corticotropin-releasing hormone or adenosine. The authors are a unique group of scientists who are all interested in brain-to-immune interactions; however, each from a different perspective. The volume will serve both neurobiologists and immunologists to understand the influence of the central nervous system on peripheral inflammation. Many aspects of this book will also be stimulating for researchers in the pain field.

Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.
