This unifying theme of this book—with sections on mechanisms of defense and neuropathogenesis, neurological diseases, infections of the nervous system, neuropharmacology, and novel therapies—is interactions of the immune and nervous systems. It also discusses the role of inflammation as a key mediator of different brain disorders. There have been significant scientific advances in the multidisciplinary field of neuroimmunology / neuroinflammation in the past decade, and this book, edited under the guidance of Professor P. N. Tandon, fosters communication between those who share an interest in this exciting area, including neuroscientists, immunologists, cell biologists, clinicians and neuropharmacologists.
