[Neuroprotective mechanisms of vascular endothelial growth factor]

Vascular endothelial growth factor (VEGF), originally discovered in tumor cells, is an angiogenic factor essential for new blood vessel formation during embryogenesis and in many pathological conditions. There is a growing body of evidence that VEGF can act directly on neurons and plays a new role as a neuroprotective factor via multiple mechanisms. Moreover, VEGF modulates neurogenesis in constitutive neurogenic and non-neurogenic regions of adult mammalian brains, which is a promising therapeutic strategy for neuronal replacement in traumatic brain injury and neurodegenerative diseases. Here, we mainly reviewed the neuroprotection of VEGF against ischemic brain injury and its mechanisms.
