Abstract

This chapter provides a comprehensive overview of the roles of astrocytes, microglia, and the extracellular matrix (ECM) in regulating neuroplasticity and maintaining brain homeostasis. Astrocytes provide essential metabolic support to neurons, regulate synapse development, support neuroplasticity mechanisms, and modulate neurotransmission. Microglia, the resident immune cells of the brain, play a critical role in neuroinflammatory responses and homeostatic brain regulation by modulating synapse formation and pruning. The extracellular space (ECS) mediates intercellular interactions, provides a highly regulated environment for intercellular communication, and is filled with ECM molecules. Proteoglycans and polysaccharides of the ECM play a vital role not only in brain development but also in brain function throughout life. In the injured brain, neuroplasticity and regeneration can be bidirectionally regulated as a result of the interplay between ECM, astrocytes, and microglia. The modulation of synaptic strength, structural remodeling, and modification of intrinsic neuronal properties are among the central mechanisms that contribute to neuronal plasticity in health and disease. We believe that the understanding of ECM-glia interactions and their role in neuroplasticity regulation is key to the development of novel therapeutic strategies in neurologic disorders.

期刊介绍： The Handbook of Clinical Neurology (HCN) was originally conceived and edited by Pierre Vinken and George Bruyn as a prestigious, multivolume reference work that would cover all the disorders encountered by clinicians and researchers engaged in neurology and allied fields. The first series of the Handbook (Volumes 1-44) was published between 1968 and 1982 and was followed by a second series (Volumes 45-78), guided by the same editors, which concluded in 2002. By that time, the Handbook had come to represent one of the largest scientific works ever published. In 2002, Professors Michael J. Aminoff, François Boller, and Dick F. Swaab took on the responsibility of supervising the third (current) series, the first volumes of which published in 2003. They have designed this series to encompass both clinical neurology and also the basic and clinical neurosciences that are its underpinning. Given the enormity and complexity of the accumulating literature, it is almost impossible to keep abreast of developments in the field, thus providing the raison d''être for the series. The series will thus appeal to clinicians and investigators alike, providing to each an added dimension. Now, more than 140 volumes after it began, the Handbook of Clinical Neurology series has an unparalleled reputation for providing the latest information on fundamental research on the operation of the nervous system in health and disease, comprehensive clinical information on neurological and related disorders, and up-to-date treatment protocols.
