Recent research has revealed the importance of immunological mechanisms and inflammation in delaying damage and/or promoting repair after an acute injury to the central nervous system. This book provides a comprehensive and up-to-date overview of the role of immunological mechanisms and therapies for treating acute neurological injuries such as cerebral ischemia, hemorrhage, and brain and spinal cord trauma. In several sections, the contributing authors provide a review of immunological mechanisms involved in neurological injury and of various translational and clinical research aimed at harnessing those mechanisms for better patient outcomes.​

Mechanisms of brain-immune interactions became a cutting-edge topic in systemic neurosciences over the past years. Acute lesions of the brain parenchyma, particularly, induce a profound and highly complex neuroinflammatory reaction with similar mechanistic properties between differing disease paradigms like ischemic stroke, intracerebral hemorrhage (ICH) and traumatic brain injury (TBI). Resident microglial cells sense tissue damage and initiate inflammation, activation of the endothelial brain-immune interface promotes recruitment of systemic immune cells to the brain and systemic humoral immune mediators (e.g. complements and cytokines) enter the brain through the damaged blood-brain barrier. These cellular and humoral constituents of the neuroinflammatory reaction to brain injury contribute substantially to secondary brain damage and neurodegeneration. Diverse inflammatory cascades such as pro-inflammatory cytokine secretion of invading leukocytes and direct cell-cell-contact cytotoxicity between lymphocytes and neurons have been demonstrated to mediate the inflammatory ‘collateral damage’ in models of acute brain injury. Besides mediating neuronal cell loss and degeneration, secondary inflammatory mechanisms also contribute to functional modulation of neurons and the impact of post-lesional neuroinflammation can even be detected on the behavioral level. The contribution of several specific immune cell subpopulations to the complex orchestration of secondary neuroinflammation has been revealed just recently. However, the differential vulnerability of specific neuronal cell types and the molecular mechanisms of inflammatory neurodegeneration are still elusive. Furthermore, we are only on the verge of characterizing the control of long-term recovery and neuronal plasticity after brain damage by inflammatory pathways. Yet, a more detailed but also comprehensive understanding of the multifaceted interaction of these two supersystems is of direct translational relevance. Immunotherapeutic strategies currently shift to the center of translational research in acute CNS lesion since all clinical trials investigating direct neuroprotective therapies failed. To advance our knowledge on brain-immune communications after brain damage an interdisciplinary approach covered by cellular neuroscience as well as neuroimmunology, brain imaging and behavioral sciences is crucial to thoroughly depict the intricate mechanisms.

The brain is a critical organ with neuro-immune communication. The nervous system and immune system evolved to provide regulation of physiological homeostasis and protect against threats. Neuro-immune communication is correlated with physiological functions of various tissues and organs, and the internal environment balance. In brain trauma, the neural network is destroyed and the neuro-immune communication process is impaired. However, the research on this process is insufficient and limited. A thorough clarification of the cellular and molecular mechanisms of neuro-immune communication in brain injury is an essential necessary endeavor in the search for new therapeutic targets for brain injury. This Research Topic is devoted to the cellular and molecular mechanisms of neuro-immune communication in brain injury and on the meaningful exploration of how the nervous system regulates the immune system to promote neurofunctional recovery after brain injury.

"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.

Brain Edema: From Molecular Mechanisms to Clinical Practice brings together the most widely recognized experts in experimental and clinical brain edema research to review the current knowledge gathered on the molecular and cellular pathophysiology and clinical management of brain edema. This timely book also discusses future directions of research and treatment. Brain edema is an integral and acutely life-threatening part of the pathophysiology of multiple cerebral and non-cerebral disorders, including traumatic brain injury, cerebral ischemia, brain tumors, cardiac arrest, altitude sickness and liver failure. Affecting millions worldwide, research over the past few years has shown that a plethora of complex molecular and cellular mechanisms contribute to this pathological accumulation of water in the brain parenchyma. In parallel, the development of new neuroimaging tools has provided a new way to examine how edema develops longitudinally and in real time, both in pre-clinical models and in patients. Despite intense research over the past few decades, therapeutic options are still limited and sometimes not effective. Presents a comprehensive understanding of the molecular mechanisms involved in edema formation and resolution Discusses the specific role of edema development in several pathologies, including traumatic brain injury, stroke, brain tumors, cardiac arrest, and liver failure Proposes a new classification of edema based on molecular processes Discusses clinical management of new clinical trials coming from pre-clinical studies Addresses the possible link between edema formation, other molecular and cellular processes, including inflammation and neuroinflammation
