Preface More than 100 years have elapsed since the discovery of the blood-brain barrier (BBB). Evolving technologies starting with tracer studies, and more recently with genomics and proteomics, have provided novel information about the molecular properties of cerebral endothelium and astrocytes. The concept of the neurovascular unit has provided an impetus for in  vitro studies of the interaction of brain endothelial cells with other components of the neurovascular unit such as pericytes, astrocytes, and neurons in steady states. However, such studies have to be done in animal models of neurological diseases and in humans to get a clearer understanding of the pathogenesis of BBB breakdown in nervous system diseases. Determination of the temporal course of BBB breakdown and the parallel molecular alterations remain important goals to identify therapeutic windows and pertinent therapeutic agents which will modify the disease process and prevent irreversible brain damage. There is also the
