Neuroglia Molecular Mechanisms In Psychiatric Disorders

Neuroglia Molecular Mechanisms in Psychiatric Disorders

Neuropsychiatric disorders have long been considered as specific dysfunctions of neuronal functions. Studies of the recent decade, however, have challenged this simplistic view, highlighting the important role played by neuroglial cells in the onset and/or progression of neuropsychiatric diseases. In the central nervous system (CNS) non-excitable neuroglia are represented by cells of ectodermal origin (astrocytes, mainly responsible for CNS homeostasis and oligodendrocytes that provide myelination and support for axons) and mesodermal origin (microglial cells that are scions of foetal macrophages entering the neural tube early in development; these cells provide for CNS defence and contribute to shaping neuronal networks). Pathological changes of neuroglia are complex; these changes are classified into reactive gliosis (astrogliosis, activation of microglia and hypertrophy of oligodendroglial precursors), gliodegeneration with loss of function and glial pathological remodelling. Combination of these processes defines the evolution of neurological diseases in general and neuropsychiatric disorders in particular. In this research topic we addressed the contribution of neuroglia to major neuropsychiatric pathologies including major depression, schizophrenia, and addictive disorders.

Neuroglia in Neurologic and Psychiatric Disorders, Part II

Neuroglia in Neurologic and Psychiatric Disorders, Part II discusses glia relative to neurologic and psychiatric disorders, emphasizing cross-disease-glial cell dysfunctions. Driven by advances in genetics, transcriptomics, electrophysiologic and imaging techniques, as well as by the increase in knowledge on neuropathologic features and underlying disease mechanisms, this book bridges the gap between neuroglia basic science and neuroglia clinical research. - Provides an overview of neuroglia biology - Identifies neuroglia dysfunction in neurologic and psychiatric disorders - Covers ALS, dementia, Alzheimer, Parkinson, Huntington diseases and more - Includes TBI, Stroke, COVID - Encompasses disorders of mood, eating, sleep, anxiety, schizophrenia, autism, and more
