The brain vasculature nurtures and regulates basic functions of the central nervous system (CNS), acting as a barrier against pathogens. This book provides in-depth and focused data on the characteristics, function and role of brain blood vessels in health and disease. It addresses topics such as vascular activity, cell-cell communication, and the role of the endothelium in the development of the most prevalent types of cerebrovascular disease, neurodegenerative disorders, cognitive impairment, and vascular abnormalities. It offers an updated view of the current state of microvascular biology and research, and thus supports the discovery of new therapeutic agents and procedures directed at several CNS disorders.
