Understanding The Roles Of Glia And Circulating Leukocytes In Neurodegenerative Diseases

Understanding the Roles of Glia and Circulating Leukocytes in Neurodegenerative Diseases

Glia in Health and Disease

The book will highlight the role played by glial cells in the central and peripheral nervous systems in both healthy and unhealthy individuals. Among all processes involved, we will discuss the importance of the enteric nervous system in the control of gut homeostasis, in the interaction with the immune system, and its participation in pathological conditions such as metabolic syndrome. We will also look at the relevance of astrocytes during synaptic transmission and the regulation of plasticity by releasing gliotransmitters. Ultimately, we will highlight the influence of astrocytes during the development of a number of neurodegenerative diseases, such as multiple sclerosis and Alzheimer’s disease, focusing on how the serum levels of the astrocytic protein S100B can be used as a biomarker for clinical decisions.

Glia and Inflammation in Neurodegenerative Disease

The brain has long been considered an immune privileged organ, meaning that inflammatory cells are excluded due to a relatively impenetrable blood brain barrier (BBB). However, this is not to say that the central nervous system is incapable of eliciting immune responses, as resident inflammatory cells exist within the brain parenchyma. Microglia have long been thought to be the brain's resident immune cell with myeloid lineage similar to monocytes and macrophages. In this volume, the authors review the current state of knowledge with regard to immune responses and cell-cell interactions as they pertain to a variety of neurodegenerative diseases. The changing role of inflammation with development is considered. They also present a summary of the various therapeutic strategies employed both in the laboratory and at the clinical level.
