Abstract

Blood-Brain Barrier Breakdown and Blood-Brain Communication in Neurological and Psychiatric Diseases

Highlights

  • Transport across the blood-brain barrier (BBB) is tightly regulated by at least four different cells that comprise the brain microvasculature: the endothelial cell and highly specific tight junctions between them, the pericytes which share with the endothelial cells a common capillary basement membrane, the astrocytic foot processes which cover the capillaries, and nerve endings which innervate the vessels

  • Dysfunction of the BBB occurs during numerous common neurological diseases, including stroke, epilepsy, trauma, tumors, and infectious and degenerative diseases

  • While it has been long recognized that BBB dysfunction is associated with brain diseases, only recently it has been suggested to play a role in the pathogenesis of neuronal networks dysfunction and degeneration
