Vascular Endothelial Growth Factor Augments the Tolerance Towards Cerebral Stroke by Enhancing Neurovascular Repair Mechanism.

The breakdown of the blood-brain barrier (BBB) is a critical event in the development of secondary brain injury after stroke. Among the cellular hallmarks in the acute phase after stroke are a downregulation of tight-junction molecules and the loss of microvascular pericyte coverage and endothelial sealing. Thus, a rapid repair of blood vessel integrity and re-stabilization of the BBB is considered an important strategy to reduce secondary brain damage.
