Neurotrophic factors regulate the development and maintenance of the nervous system and protect and repair dopaminergic neurons in animal models of Parkinson's disease (PD). Vascular endothelial growth factors A (VEGF-A) and B have also neurotrophic effects on various types of neurons, including dopaminergic neurons. We examined the ability of the key lymphangiogenic factor VEGF-C to protect dopaminergic cells in vitro and in vivo. The study was initiated by a finding from microarray profiling of Neuro2A-20 cells which revealed up-regulation of VEGF-C by glial cell-line-derived neurotrophic factor (GDNF). Next, we observed that VEGF-C can rescue embryonic dopaminergic neurons and activate the mitogen-activated protein kinase/extracellular signal regulated kinase (MAPK/ERK) pathway in vivo. VEGF receptors 1-2 and co-receptors, neuropilins 1-2, were expressed both in mouse embryonic cultures and adult midbrains. In vivo, VEGF-C had a robust functional effect in the rat unilateral 6-hydroxydopamine (6-OHDA) model of PD and there was a small additive effect on the survival of tyrosine hydroxylase (TH)-positive cells with GDNF. The neuroprotective effect of VEGF-C is most likely due to a combination of direct and indirect neurotrophic effects because, VEGF-C, unlike GDNF, induced also angiogenesis in the striatum following 6-OHDA insult as it did in human umbilical vein endothelial cells (HUVEC). However, we detected activation of astroglia and microglia as well as blood-brain barrier disruption after intracerebral delivery of VEGF-C, raising a concern of its safe usage as a therapeutic molecule. Our results provide evidence of VEGF-C as a neurotrophic factor that influences the dopaminergic system through multiple mechanisms.
