Abstract
The vascular endothelial growth factor (VEGFA, VEGF) regulates neurovascular patterning. Alternative splicing of the Vegfa gene gives rise to three major isoforms termed VEGF121, VEGF165 and VEGF189. VEGF165 binds the transmembrane protein neuropilin 1 (NRP1) and promotes the migration, survival and axon guidance of subsets of neurons, whereas VEGF121 cannot activate NRP1-dependent neuronal responses. By contrast, the role of VEGF189 in NRP1-mediated signalling pathways has not yet been examined. Here, we have combined expression studies and in situ ligand-binding assays with the analysis of genetically altered mice and in vitro models to demonstrate that VEGF189 can bind NRP1 and promote NRP1-dependent neuronal responses.File | Dimensione | Formato | |
