The system of processes and structures which consists of interactions between the nervous system and the immune system is termed as the neuroimmune system. It involves electrophysiological and biochemical processes, and is integral in protecting the neurons from pathogens. Sensory neurons and immune cells are used by the neuroimmune system for the detection and management of harmful stimuli. The neuroimmune system is primarily comprised of glial cells. Neurons and glial cells work together to deal with attacking pathogens. Both glial cells and neurons express chemokine receptors, thus chemokines act as mediators in neuron-glial cell interaction. Different approaches, evaluations, methodologies and advanced studies on neuroimmune interactions and their clinical aspects have been included in this book. It presents this complex subject in the most comprehensible and easy to understand language. This book will serve as a valuable source of reference for graduate and post graduate students.

The nervous system plays an important role in the regulation of immunity and inflammation. On the other hand unbalanced immune responses in inflammatory and autoimmune conditions may have a deleterious impact on neuronal integrity and brain function. Recent studies have characterized neural pathways communicating peripheral inflammatory signals to the CNS, and brain- and spinal cord-derived circuitries controlling various innate and adaptive immune responses and inflammation. A prototypical neural reflex circuit that regulates immunity and inflammation is the vagus nerve-based “inflammatory reflex”. Ongoing research has revealed cellular and molecular mechanisms underlying these neural circuits and indicated new therapeutic approaches in inflammatory and autoimmune disorders. Pharmacological and bioelectronic modulation of neural circuitry has been successfully explored in preclinical settings of sepsis, arthritis, inflammatory bowel disease, obesity-driven disorders, diabetes and other diseases. These studies paved the way to successful clinical trials with bioelectronic neuronal modulation in rheumatoid arthritis and inflammatory bowel disease. Dysregulated release of cytokines and other inflammatory molecules may have a severe impact on brain function. Brain inflammation (neuroinflammation), imbalances in brain neuronal integrity and neurotransmitter systems, and cognitive impairment are characteristic features of post-operative conditions, sepsis, liver diseases, diabetes and other disorders characterized by immune and metabolic dysregulation. Derangements in cytokine release also play a pivotal role in depression. Characteristic brain reactive antibodies in autoimmune conditions, including systemic lupus erythematosus and neuromyelitis optica, significantly contribute to brain pathology and cognitive impairment. These studies, and the simultaneous characterization of neuro-protective cytokines, identified new therapeutic approaches for treating neurological complications in inflammatory and autoimmune disorders. This Frontiers Research Topic is a forum for publishing research findings and methodological and conceptual advances at the intersection of immunology and neuroscience. We hope that presenting new insight into bi-directional neuro-immune communication in inflammation and autoimmunity will foster further collaborations and facilitate the development of new efficient therapeutic strategies.

It is now well appreciated that the immune system, in addition to its traditional role in defending the organism against pathogens, communicate in a well-organized fashion with the brain to maintain homeostasis and regulate a set of neural functions. Perturbation in this brain-immune interactions due to inflammatory responses may lead to psychiatric and neurological disorders. Microglia are one of the essential cells involved in the brain-immune interactions. Microglial cells are now not simply regarded as resident tissue macrophages in the brain. These cells are derived from myeloid progenitor cells in the yolk sac in early gestation, travel to the brain parenchyma and interact actively with neurons during the critical period of neurogenesis. Microglia provide a trophic support to developing neurons and take part in the neural wiring through the activity-dependent synapse elimination via direct neuron-microglia interactions. Altered microglial functions including changes in the gene expression due to early life inflammatory events or psychological and environmental stressors can be causally related to neurodevelopmental diseases and mental health disorders. This type of alterations in the neural functions can occur in the absence of infiltration of inflammatory cells in the brain parenchyma or leptomeninges. In this sense, the pathogenetic state underlying a significant part of psychiatric and neurological diseases may be similar to “para-inflammation”, an intermediate state between homeostatic and classical inflammatory states as defined by Ruslan Medzhitov (Nature 454:428-35, 2008). Therefore, it is important to study how systemic inflammation affects brain health and how local peripheral inflammation induces changes in the brain microenvironment. Chronic pain is also induced by disturbance in otherwise well-organized multisystem interplay comprising of reciprocal neural, endocrine and immune interactions. Especially, early-life insults including exposure to immune challenges can alter the neuroanatomical components of nociception, which induces altered pain response later in life. Recently the discrete roles of microglia and blood monocyte-derived macrophages are being defined. The distinction may be further highlighted by disorders in which the brain parenchymal tissue is damaged. Therefore, studies investigating the dynamics of immune cells in traumatic brain injury and neurotropic viral infections including human immunodeficiency virus, etc. as well as neurodegenerative diseases such as amyotrophic lateral sclerosis are promising to clarify the interplay between the central nervous and immune systems. The understanding of the histological architecture providing the infrastructure of such neuro-immune interplay is also essential. This Frontiers research topic brings together fourteen articles and aims to create a platform for researchers in the field of psychoneuroimmunology to share the recent theories, hypotheses and future perspectives regarding open questions on the mechanisms of cell-cell interactions with chemical mediators among the nervous, immune and endocrine systems. We hope that this platform would reveal the relevance of the studies on multisystem interactions to enhance the understanding of the mechanisms underlying a wide variety of neurological and psychiatric disorders.

As lifespans increase, more people around the world find themselves victims of chronic pain. In spite of this, treatment options continue to be severely limited. Anti-inflammatory drugs can only do so much, while painkillers like opioids have led to crippling addictions and fatal overdoses. The subject of the book is the role of immune cells, including glial cells, and neuroimmune interactions in chronic pain. The book begins by examining the preclinical and clinical evidence supporting the involvement of non-neuronal cells in chronic pain. It discusses the interactions between non-neuronal cells and neurons in the regulation of chronic pain. It then presents the implications of these findings, including promising and emerging treatments such as specialized pro-resolving mediators (SPMs, such as resolvins and protectins), immune cell therapy, and complementary and alternative medicine, as well as neuromodulation and regenerative medicine, which may prove to be the turning point for hundreds of millions of patients world-wide who struggle to escape from the shadow of chronic pain. The book presents ground-breaking research that will alter current perspectives on chronic pain.

For those of us involved in research on the neural mechanisms that relate tissue damage to pain. it is becoming more evident that the sensation of pain and suffering could be considered as part of a mechanism that involves not only sizeable areas in the brain but also simultaneous activations of the immune and the endocrine systems as well. A consensus is growing among specialists in the field that pain involves the sharing of molecular mechanisms between the nervous, immune and endocrine systems that can interact at peripheral and, ultimately, central levels. Furthermore, chronic pain could then be looked upon as a corollary of the imbalance in the cross talk between these systems, which could lead to new treatment strategies. The aim of this book is not to deal with acute pain that serves as an alarm signal, but to attempt to explain the molecular mechanisms of chronic pains considered as a multifactorial syndrome or disease.

Neuroimmunology is a rapidly growing emerging field at which two old sciences have converged to integrate two different types of responses into a single coherent response involving the coordinated action of both systems, neural and immune. During long time it was thought that both systems worked separately and in divergent pathways. The brain was considered an immunoprivileged site and the immune organs were deemed as independent of any neural influence and also of nervous innervation. Time has gone and has proven that the borders between both systems were merely artificial. Since the beginning of Neuroimmunology in the 1980s much work has been done to elucidate the gates and fences in neuro-immune interactions. Brain was shown to be under the continuous surveillance of the immune system, even under basal physiological conditions in the absence of any pathology. Likely, it was found a profuse nervous innervation of lymphoid organs and even of single immune cells. Gates for direct neural immune communication were found both centrally and peripherally. Centrally, the gates, but also the fences, were situated at the brain barriers, the blood-brain barrier and the blood-cerebrospinal fluid barrier, and at the circunventricular organs. Peripherally, the fences constituted the apparent diverse nature of molecules involved in neural and immune signaling; however, time proved that both system were capable of producing the same signaling molecules and also systematically responded to the molecules released by the other system. Therefore, the gates were open for direct neural-immune communication at the peripheral level. This Research Topic aimed to include original reports, reviews and technical reports regarding the description of the gates and fences in neural immune interactions. We intended to provide an extensive view of the mechanisms governing central and peripheral neural-immune interactions, and the role of the borders, the blood-neural barriers, in the regulation of the neural-immune communication.

The idea that the brain is an "immune-privileged site" has perhaps served to slow our realization that the intact brain can generate its own inflammatory reactions. These responses can be to peripheral infection, or they can arise from local, internal causes, for instance as a response to stress or to the se vere changes in neuronal activity in seizure or the loss of oxygen in stroke. We are also becoming increasingly aware of the contribution of local inflam matory reactions to certain neurodegenerative diseases such as Alzheimer's In fact, evidence is accumulating that inflammatory processes disease (AD). contribute to the progression of AD, suggesting the possibility of using cur rently available or novel anti-inflammatory agents to interfere with this terri ble disease. Correlations are also being made between inflammatory signs and mental illness, which is a new frontier of research. This book presents the current state of knowledge in a variety of areas relevant to neuro-immune interactions, with particular attention to AD.
