Abstract

Perinatal hypoxic-ischemic brain injury is a relevant medical and social problem. Among many pathological processes in the neonatal period perinatal hypoxic-ischemic injury is a major cause of further hemorrhage, necrotic and atrophic changes in the brain. This review presents recent data on the basic mechanisms of the hypoxic-ischemic brain injury along the concept of neurovascular unit (neurons, astrocytes, endothelial cells, pericytes) with the focus on alterations in cell-to-cell communication. Pathological changes caused by ischemia-hypoxia are considered within two phases of injury (ischemic phase and reperfusion phase). The review highlights changes in each individual component of the neurovascular unit and their interactions. Molecular targets for pharmacological improvement of intercellular communication within neurovascular unit as a therapeutic strategy in perinatal brain injury are discussed.
