The blood-brain barrier (BBB) is one of the most important interfaces that keep the homeostasis of brain. However, it also prevents drugs from entering in morbid state. VEGF is an important growth factor that promotes neovascularization. We think it might be helpful to increase the permeability of the BBB. To test this hypothesis, we used KM mice with the venous injection of Hu-VEGF165 and detect the permeability of the BBB both in MRI and histological methods. We find that VEGF can increase the permeability of the BBB and may be a new direction for the CNS drugs delivery.
