Spinal cord injury (SCI) leads to local vascular disruption and progressive ischemia, which contribute to secondary degeneration. Enhancing angiogenesis through the induction of vascular endothelial growth factor (VEGF)-A expression therefore constitutes an attractive therapeutic approach. Moreover, emerging evidence suggests that VEGF-A may also exhibit(More)
Following spinal cord injury (SCI) there are drastic changes that occur in the spinal microvasculature, including ischemia, hemorrhage, endothelial cell death and blood-spinal cord barrier disruption. Vascular endothelial growth factor-A (VEGF-A) is a pleiotropic factor recognized for its pro-angiogenic properties; however, VEGF has recently been shown to(More)
We report the generation and use of pseudotyped adeno-associated viral (AAV) vectors for the liver-specific expression of human blood coagulation factor IX (hFIX). Therefore, an AAV-2 genome encoding the hfIX gene was cross-packaged into capsids of AAV types 1 to 6 using efficient, large-scale technology for particle production and purification. In(More)
OBJECTIVE The objectives of the study were to evaluate retrograde axonal transport of vascular endothelial growth factor A (VEGF-A) protein to sensory neurons after intramuscular administration of an engineered zinc finger protein activator of endogenous VEGF-A (VZ+434) in an experimental model of diabetes, and to characterize the VEGF-A target neurons.

Recent studies have identified anti-apoptotic functions for vascular endothelial growth factor (VEGF) in the central nervous system (CNS). However, VEGF therapy has been hampered by a tendency to promote vascular permeability, edema, and inflammation. Recently, engineered zinc finger proteins (ZFPs) that upregulate multiple forms of VEGF in their natural(More)
Vascular endothelial growth factor (VEGF) plays a role in angiogenesis and has been shown to be neuroprotective following central nervous system trauma. In the present study we evaluated the pro-angiogenic and neuroprotective effects of an engineered zinc-finger protein transcription factor transactivator targeting the vascular endothelial growth factor A(More)
