Neural and Glial Regulation of Angiogenesis in CNS in Ischemic Stroke

CNS diseases associated with compromised blood supply and/or vascular integrity are one of the leading causes of mortality and disability in adults worldwide and are also among 10 most common causes of death in children. Angiogenesis is an essential element of regeneration processes upon nervous tissue damage and can play a crucial role in neuroprotection. Here we review the features of cerebral vascular regeneration after ischemic stroke, including the complex interactions between endothelial cells and other brain cell types (neural stem cells, astrocytes, microglia, and oligodendrocytes). The mechanisms of reciprocal influence of angiogenesis and neurogenesis, the role of astrocytes in the formation of the blood-brain barrier, and roles of microglia and oligodendrocytes in vascular regeneration are discussed. Understanding the mechanisms of angiogenesis regulation in CNS is of critical importance for the development of new treatments of neurovascular pathologies.
